Who Should Read this Book? This workbooks primary audience is for those CCIE candidates that are searching for the most comprehensive and error-‐free materials available covering the CCIE Data Center practical lab exam. These students should possess a home rack of equipment for CCIE-‐level command-‐line practice, they should possess an equipment emulator (for certain parts of the topology), or they should rent equipment from a company like www.proctorlabs.com. The authors and technical editors exhaustively tested all of the demonstrations found throughout the technology tasks, troubleshooting-‐ and full-‐scale lab exercises against all practice rack options described earlier. Where issues arise with popular equipment emulators, the text makes note. This book is the most remarkably thorough and technically accurate book written on the CCIE Data Center lab exam to date. How to Use this Book This book breaks all specific CCIE Data Center technologies down on a chapter-‐by-‐chapter basis for a complete and thorough review of this broad set of topics. Each chapter is broken down is various tasks regarding the subject. Following this, the Detailed Solutions Guide provided with this workbook provides an intense examination of the operation of the tasks, including key aspects of troubleshooting for the specific technology. After this, the book presents some of the most common issues that can result with a particular technology-‐set, and most importantly, details the simple troubleshooting tools and steps that succeed for remediation. The final chapters conclude the book with sample lab scenarios that provide a full scale lab exam as you will see it when you take the actual test. The Detailed Solutions Guide then provides a well-‐designed approach for troubleshooting each major task and offers detailed explanations. The text provides reference guides for the most popular and powerful show and debug commands for a specific technology. Each chapter uses specific initial configurations on the specific chapter. Readers may download initial configurations, or install them in a simple Graphical User Interface (GUI) on www.proctorlabs.com. Students are encouraged to follow along on a rack of equipment for every section of every chapter. This really enhances and strengthens the learning process. An Introduction to CCIE Data Center Since the release of the Nexus platform there has been talk about when these platforms were to be introduced in a CCIE track. With the introduction of UCS in 2009 this became an even higher request especially since UCS really took off in sales. Copyright © by IPexpert. All rights reserved.

The scope of the exam is pretty much based on the usual suspects, so in summary you should be aware of the: •
•

•
•
•
•
•
•
UCS B-‐series blade systems UCS C-‐series rackmount systems connected to UCS Manager via FEX Virtual Interface Cards (virtualized NICs and HBAs) in all servers Nexus 7000 with all features like VDC, OTV, FabricPath, etc. Nexus 5500 with all features like FCoE, FEX Nexus 2000 connected to either the 5k or the 7k Nexus 1000V distributed virtual switch in ESX o There is no mention of any VMware product in the blueprint, so expect ESX and vCenter to be pre-‐installed on the UCS blades and FC boot to pre-‐configured disks MDS 9222i for connecting FC storage to UCS ACE appliance DCNM management software Availability The live exam is available from September 1st. Currently there are no dates when the lab is available. Written exam The written exam has an extensive blueprint published to Cisco Learning Network (CLN) including a reading list. The current published reading list: Data Center Fundamentals (ISBN-10: 1-58705-023-4) NX-OS and Cisco Nexus Switching (ISBN-10: 1-58705-892-8) Cisco Unified Computing System (UCS) (ISBN-10: 1-58714-193-0) I/O Consolidation in the Data Center (ISBN-10: 1-58705-888-X) Storage Networking Fundamentals (ISBN-10: 1-58705-162-1) Copyright © by IPexpert.

Please find the extensive blueprint published by Cisco on the bottom of this blog post.
Lab exam There is not much information available regarding the lab exam. Availability is not mentioned. There is however information regarding the hardware list and this is an immense list of expensive hardware you require: Software Versions •

NXOS v6.0(2) on Nexus 7000 Switches NXOS v5.1(3) on Nexus 5000 Switches NXOS v4.2(1) on Nexus 1000V NXOS v5.2(2) on MDS 9222i Switches UCS Software release 2.0(1x) for UCS-‐6248 Fabric Interconnect and all UCS systems Software Release A5(1.0) on ACE4710 Cisco Data Center Manager software v5.2(2) CCIE Storage? There are currently no plans for replacing CCIE Storage for CCIE Datacenter. Because of this, there will not be a large focus on MDS/FC configuration as there is another track for that. What about P and A tracks? A CCNA Data Center and CCNP Data Center will be released soon! Troubleshooting Troubleshooting will be a big part of the exam, which is also pretty clear in the blueprint. There is no confirmation yet how this will be introduced, either using tickets in the CCIE R&S or just by pre-‐
configuration on the lab. I can imagine that they pre-‐configured a broken Nexus 1000V on an ESX installation on one of the JBODs. More information on how this troubleshooting is done will be available during other Q&A sessions. The implication is that it might be trouble tickets like the CCIE R&S. Copyright © by IPexpert.

An Introduction to the Proctor Labs CCIE Data Center hardware rack The IPexpert CCIE Data Center rack will support 100% of the features that are tested on the lab! We have based the topology to be close as possible on the CCIE Data Center rack layout, but have ensured that all features and functionality is there. Our CCIE Data Center rack layout is based on the very limited information that has been made available by Cisco. IPexpert has been in close contact with the people involved in creating this lab exam, and therefore the layout of the rack is based on some early examples and the published components and software version blueprint. As you will see the topology is very much based on a common datacenter design and has more 'static' layout than other CCIE tracks. The blueprint specified the following components to be in the lab: First is the NX-‐OS Networking equipment. •
•
•
Nexus7009 (with licensing) o (1) Sup o (1) 32 Port 10Gb (F1 Module) o (1) 32 Port 10Gb (M1 Module) Nexus5548 Nexus2232 The Nexus 7000 will be configured with VDC's to simulate various different topologies and create multiple 'core switch' layers within the network. Nexus 5548 will be used as a 'distribution' layer within the datacenter network. The Nexus 2k's can be configured as FEX for the Nexus 7000; Nexus 5000 and the Fabric Interconnects of the UCS system to connect the UCS C-‐series rack mount servers. The VDC's are a major component in the network as the number of devices is limited and the connectivity is very much based on a best practice design. The below drawing illustrates an example topology from our new CCIE Data Center lab preparation workbook which is currently under development. All these interconnections and switches are based within a single physical chassis with complete separation of the control and data plane protocols! Copyright © by IPexpert. All rights reserved.

Second is the storage networking (SAN) equipment: •
•
Dual attached JBODs = Fibre Channel disks MDS 9222i (dual fabric) The MDS switches used in the lab are capable of a ton of features. The blueprint however only describes certain fibre-‐channel features which are considered 'basic' features like zoning, VSANs, oversubscription and ISLs. The other major topic on the blueprint is Fibre Channel Expansion over FCIP and iSCSI. These features are the IP features supported by the MDS platform. The 1G Ethernet connections are connected to the Nexus switches for testing the expansion features. Through that connection it's possible to connect the MDS switches across another connection than Fibre Channel. As the CCIE Storage track is not being replaced by the CCIE Data Center the focus on Storage Networking (SAN) features is not that big. The major topics are more in the features that aren't tested in any other CCIE track. The JBODs mentioned in this list represent just plain simple hard-‐disks that are connected via Fibre Channel. They are used later as shared storage for the UCS system. The third major component within the hardware blueprint is the Unified Computing System (UCS). •
•
•
UCS-‐6248 Fabric Interconnects UCS-‐5108 Blade Chassis o B200 M2 Blade Servers o Palo/VIC mezzanine card o Menlo/Emulex mezzanine card UCS C200 Series Server = Connected to Fabric Interconnects o VIC card for C-‐series Copyright © by IPexpert. All rights reserved.

This is based on the C-‐series rackmount servers, connected to the Fabric Interconnects so the C-‐series can also be managed from the central UCS manager the same as the Blade chassis is managed. The blades are equipped with different NICs. This also means a little different configuration. The VIC cards are the most interesting ones as they can virtualize NICs to present to the OS. Ones inside the blades there is a pre-‐installed VMware ESX(i) environment with a Nexus 1000v distributed virtual switch. As this is a Cisco lab exam, you are not required to know anything about VMware. Of course you will need to be able to install this environment in your possible own lab, but when you step into the lab you will face a pre-‐installed VMware and 1000V. After that, the switch is not configured and you are required to configure it. The final topic on the blueprint is called ANS (Application Networking Services). This means an ACE appliance is in your lab that you will need to configure. There is not much very interesting going on there and you will not see a lot of points on that appliance. You will need to know the topics as described on the lab blueprint and our workbook will focus a whole section on these specific topics. The last components are used for management. You will not be configuring these devices, but just using them from your student workstation to access the network. •
•
Cisco Catalyst Switch 3750 = management ethernet connections Cisco 2511 Terminal Server = console lines What is not mentioned on the hardware blueprint list is that you will also need to be able to configure (or set-‐up) the DCNM software as is being given by Cisco when you purchase enough Nexus equipment. Again this is not extremely difficult, but you need to be aware of the basic configuration items related to this software. Software Versions •

Software Release A5(1.0) for ACE 4710 Cisco Data Center Manager software v5.2(2) Above you'll find a reference overview of the used software versions. The exact versions are still unknown where we might be using newer software versions as our IPexpert lab will be using quite new hardware for virtualization purposes. Within the Nexus 7000 we will be using the new Supervisor 2E, meaning that we are able to build 8 VDC's and 1 management VDC meaning we have enough flexibility for some challenging topologies! The next chapter of this workbook, Chapter 2: Data Center Networking Layer 2 Infrastructure (NX-‐OS) begins with the initial topic on the CCIE Data Center Blueprint regarding layer 2 switching, VLANs, Private-‐VLANs, Spanning-‐Tree and other layer 2 features on the NX-‐OS platform.

Chapter 2: Data Center Networking Layer 2 Infrastructure (NX-‐OS) Chapter 2: Data Center Networking Layer 2 Infrastructure (NX-‐OS) is intended to let you be familiar with the NX-‐OS CLI on the Nexus switches and afterwards configure Layer 2 Ethernet features on the physical Nexus switches within the topology as shown at the beginning of this workbook. We highly recommend to create your own diagram at the beginning of each lab so you are able to draw on your own diagram, making it much easier when you step into the real lab. Our devices start with a blank configuration, which will not be the case when you are in the real lab. Then devices are staged with configuration containing usernames/passwords, management IP addressing, core IP addressing and (possible) errors. Copyright © by IPexpert. All rights reserved.

Configuration tasks Task 1: General set-‐up 1. Erase the configuration from all 3 switches and reboot and 2. Configure the default parameters as mentioned in in the Generic Lab Topology 3. Configure the Nexus 7000 switch with a hostname of “SW1-‐1” and the Nexus 5500 switches with hostnames of “SW2” and “SW3” 4. Ensure the switches will not perform any DNS lookups 5. Configure “ipexpert.com” as the DNS domain name 6. Ensure that both encrypted and unencrypted management connections are allowed 7. Save the configuration using the wr command 8. On SW1-‐1 configure a message, containing the hostname and warning unauthorized users, that is shown each time a user logs in 9. Use the serial number of “SW1-‐1” as the ID which is used to advertise the switch using CDP 10. Ensure only CDP version 2 packets are sent from “SW1-‐1” 11. Disable CDP on the management ethernet interface 12. Ensure a log message is generated when more than 999 packets per second are sent or received on the management ethernet interface Task 2: Implement VLANs 1. Configure all inter-‐switch links as described by the topology drawing at the beginning of this chapter to be in layer 2 trunk mode allowing VLANs 100 up to 499 2. After specifying the allowed range, remove VLAN 333 from this range with a single command, without specifying the previous range (or parts of it) again 3. Configure all switches to be in VTP domain “IPexpert” 4. Ensure VLANs are removed from switches that have no active hosts in that VLAN, except for VLAN 101. This VLAN 101 should always be active on the switch not depending on this configuration task 5. Enable the latest version of VTP 6. Store the VTP database configuration with filename ‘ipexpert.dat’ Copyright © by IPexpert. All rights reserved.

Task 3: Implement Private-‐VLANs Note: This lab will be using unused ports in the topology to simulate hosts being connected. For clarification of the tasks it’s advisable to read the entire task before starting your configuration. 1. A firewall is connected to Ethernet3/19 on SW1-‐1 which should receive all traffic from DMZ hosts. This port should be in VLAN 200. You are allowed to change configuration from the previous task to accomplish this. Copyright © by IPexpert. All rights reserved.
22
2. Ensure that hosts in VLAN 201 are not able to communicate with each other, but only to the firewall connected to Ethernet3/19 3. Configure ports Ethernet3/20 and Ethernet3/21 in VLAN 201 4. Hosts in VLAN 202 and 203 are able to communicate to each other in the VLAN and to the firewall, but not to hosts in the other VLAN (202 can’t communicate with 203 and vice versa) 5. Configure ports Ethernet3/22 and Ethernet3/23 in VLAN202. Configure ports Ethernet3/24 and Ethernet3/25 in VLAN203 6. DMZ servers in VLAN 204 need to be secured. They are not allowed to communicate to each other, but they can communicate with the rest of the IP network by reaching a default gateway configured on SW1-‐1 with IP address 10.1.10.254/24
7. Hosts connected in VLAN 204 are connected on SW2. Configure the first trunk connection for this use. Configure Ethernet 1/21, 1/22 and 1/23 in VLAN205 on SW2 and ensure they are able to reach the default gateway to the network. Hosts are not allowed to communicate to each other. 8. Other hosts of VLAN 201 and 202 are also connected to SW2. Use the second trunk connection between SW1 and SW2 for this use. The hosts of VLAN201 are connected to ports Ethernet 1/24 and 1/25. The host of VLAN 202 is connected to Ethernet 1/26 Task 4: Implement Rapid Spanning-‐Tree protocol 1. Ensure non-‐core-‐facing interfaces on SW2 and SW3 are not generating any spanning-‐tree topology changes 2. Configure SW2 to be the root bridge for VLAN 101 and SW3 to be the backup root bridge 3. Ensure all switches are using optimal spanning-‐tree timers for the size of the layer 2 network to optimize network convergence. Do not configure timer values to complete this task. 4. Configure SW1 to be the root bridge for VLAN 102 5. Ensure that new bridges with a default spanning-‐tree configuration will never be elected as a root bridge in VLAN 102 when SW1 fails 6. When traffic steering is necessary, you are required to use values higher than 100,000 7. Configure the network in such a way that SW1 is using SW3 as the best path towards the root bridge of the network in VLAN 101 8. Ensure that the last interface (fourth link) between all switches is used as primary Copyright © by IPexpert. All rights reserved.
23
9. Configure spanning-‐tree of VLAN 103 to converge in the shortest time possible 10. Configure all inter-‐switch-‐links to utilize IEEE 802.1w ‘Rapid Connectivity’ 11.

5. Map VLAN 10 through 99 to instance 1 6. Map VLAN 100 through 199 to instance 2 7. Map VLAN 800 through 1299 to instance 3 8. Ensure MST is functioning properly on all switches 9. Assume Private VLANs are in use. Ensure that all secondary VLANs are in the same MSTI as their associated primary VLAN 10. Configure SW2 to be the root bridge for instance 1 by configuring the lowest possible value 11. Try making SW3 the primary root bridge for instance 1 using the dedicated command for this. What happens? 12. Make SW3 the backup root bridge for instance 1. You are allowed to configure other switches, but not SW3. 13. Ensure all switches are using optimal spanning-‐tree timers for the size of the layer 2 network to optimize network convergence. 14. When traffic steering is necessary, you are required to use values higher than 100,000 15. Configure the network in such a way that SW1 is using SW3 as the best path towards the root bridge of the network in instance 2 16. Ensure that all instances use a different interface between the switches to ensure load balancing between instances. Meaning instance 0 uses interface 1, etc. Copyright © by IPexpert. All rights reserved.
24
17. Ensure BPDUs are discarded when the network is larger than 10 hops 18. Assume a switch with an old version of software is connected to Ethernet 1/16 on SW2. Configure this interface to pro-‐actively send pre-‐standard MST messages Task 6: Spanning-‐Tree and UDLD features 1. Configure SW3 so that all ports, when not configured individually, are seen as network edge ports 2. Configure Ethernet 1/10 on SW3 so the port is put in error-‐disabled state when spanning-‐tree packets are received 3. Configure Ethernet1/11 on SW3 so the port will never process spanning-‐tree protocol data units, but will allow other layer 2 frames 4. Ensure that Ethernet 1/10 on SW2 will also never process spanning-‐tree protocol packets, but you are not allowed to configure the command required for this directly under the interface 5. Ensure Ethernet 1/11 on SW2 will never become a root port on the switch 6. Ethernet1/12 on SW2 should never become the designated port of the LAN segment 7. Assume the network is running MST and Ethernet 1/13 on SW3 is connected to a Rapid-‐PVST+ network. Ensure that this port will fail to interoperate with this other kind spanning-‐tree protocol for security reasons. 8. Use a Cisco-‐proprietary protocol which allows devices that are connected through fiber or copper cables to monitor the physical configuration of the cables and detect when a unidirectional link exists on Ethernet 1/12 on SW3 9. Use a method on Ethernet 1/12 on SW3 which disables one of the ports on the link, which prevents traffic from being discarded. Task 7: Fabric Extenders 1. Use SW2 and FEX1 for these tasks 2. Name the fabric extender as “IPexpert Fabric Extender 1” 3. Ensure the LED on the FEX starts blinking for easier locating the FEX in a rack 4. Ensure the output of the following show command is matched on SW2: Copyright © by IPexpert. All rights reserved.

38
Configuration tasks Task 1: Topology set-‐up 1. Configure the Nexus 5500 switches with hostnames of “SW2” and “SW3”. The Nexus 7000 VDC’s should already have hostnames through the loading of the initial configuration. Use switchto
vdc and switchback to move between different switches on the Nexus 7000. 2. Create the VLANs as are required on the switches as shown in drawing 2 3. Configure IP addressing on SVI and interfaces according to drawing 2
4. Configure all switches to have a Loopback0 interface with an IP address of 198.18.0.Z/32 where Z is the router number / host address as specified in drawing 2
Task 2: Port-‐Channels 1. Configure Ethernet3/1 and Ethernet3/2 on SW1-1 and Ethernet1/1 and Ethernet
1/2 on SW2 to be a single logical connection to carry the VLAN required as stated in drawing
2. Use number 1 for this connection. 2. Configure Ethernet3/5 and Ethernet3/6 on SW1-2 and Ethernet1/1 and Ethernet1/2 on SW3 to be a single logical connection to carry the VLAN required as stated in drawing 2. Use number 2 for this connection. 3. Configure logical interface 1 to negotiate it’s bundling capabilities between the switches 4. SW2 should never actively start negotiating link bundling 5. Logical interface 1 is used for bandwidth reasons and should therefore shutdown when there is less than 20Gbps capacity available in the bundle 6. Logical interface 1 should mark interfaces as hot-‐standby when additional interfaces are added to the bundle 7. Configure Ethernet1/5 and Ethernet1/6 on SW2 and SW3 to negotiate a link bundle. Use number 3 for this interface. 8. Configure logical interface 3 with IP addressing in the 198.18.23.0/24 subnet. Use host IP addresses as previously used for these switches. 9. Ensure that when no dynamic link bundling advertisements are received on an interface on logical interface 3. The physical interface is brought up in an Individual state. Copyright © by IPexpert. All rights reserved.
39
10. There are plans to increase the capacity between SW2 and SW3 to 80Gbps with additional interfaces for resiliency purposes. Ensure that Ethernet1/5 is always chosen to participate in the bundle and Ethernet1/6 should be selected as a hot-‐standby link when additional interfaces are added to the bundle. 11. Logical interface 3 should use a very fast detection mechanism to signal the removal of an interface in the bundle 12. Configure SW2 and SW3 to load-‐balance between the interfaces in link-‐bundles using the most packet header information as possible. 13. Remove any configuration related to interface bundle 1 and 2 from the switches before continuing with the next task Task 3: Virtual Port-‐channels (vPCs) 1. Ensure it’s possible to create Multi-‐Chassis Link Aggregation Groups (link bundles) on SW1-1
and SW1-2. Use ID 100 for this. 2. SW1-2 should be the primary device 3. Ensure it’s possible to create Multi-‐Chassis Link Aggregation Groups (link bundles) on SW2 and SW3. Use ID 200 for this. 4. Send keep alive messages across the mgmt0 interfaces of domain 200 switches 5. Use a dedicated SVI with IP addressing in the subnet of 198.18.5.0/24 to send keep alive messages between switches in domain 100. Ensure that the keep alive messages are not using the global IP routing table. Use Ethernet3/10 on SW1-1 and Ethernet 3/12 on SW1-2 for this. 6. Configure Ethernet3/9 on SW1-1 and Ethernet3/11 on SW1-2 as peer-‐link 7. Bundle Ethernet1/7 and Ethernet1/8 on SW2 and SW3 and configure this as the peer-‐
link 8. Ensure domain 100 brings up its vPCs once a peer fails or reboots. Delay this process for 5
minutes. 9. SW2 and SW3 should be seen as a single Spanning-‐Tree root with a priority of 8192 10. Configure an MC-‐LAG connection between SW1-1, SW1-2 and SW2. Use Ethernet3/1 on SW1-1. Ethernet3/3 on SW1-2 and Ethernet1/1 and Ethernet 1/2 on SW2. Use number 101 for this connection Copyright © by IPexpert. All rights reserved.
40
11. Configure a vPC connection between SW2, SW3 and SW1-2. Use Ethernet3/5 and Ethernet3/7 on SW1-2, Ethernet1/3 on SW2 and Ethernet1/3 on SW3. Use number 102 for this connection. 12. Use the remaining connections between SW1-1, SW1-2, SW2 and SW3 and bundle them in a single logical interface with number 103. 13. Ensure all VLANs required for Drawing 2 are allowed on the vPC links 14. Use 1234.5678.90ab as the single MAC address that is used for the identification of domain 100 LACP packets Task 4: Graceful Restart / Non-‐Stop Forwarding 1. Configure dynamic routing protocols according to drawing 2. Ensure Loopback interfaces of SW2 and SW1-1 can ping each other and SW1-2 and SW3 can ping each other 2. Ensure that the routers running OSPF keep their routing information and keep forwarding traffic to neighbors when they are rebooting 3. An older router that will take a little over 2 minutes to reboot will be connected to SW2. Ensure that your configuration supports this 4. Ensure that SW3 supports ISSU 5. SW3 should keep routes from restarting neighbors for 5 minutes 6. Signal a restart as fast as possible on SW3
Task 5: HSRP 1. Ensure that hosts on VLAN 111 are always able to reach their default gateway, when one of the 2 switches fails 2. Use a Cisco proprietary protocol for this use, which uses a single active default gateway 3. Use the .1 host IP address as the default gateway for this network segment 4. Make the switches primary and backup according to the best practice 5. Use a hashed key of “IPexpertYEAR1” to secure this protocol from now until December 31st the same year. At January 1st one year later the key should change to “IPexpertYEAR2”. Ensure that switches keep accepting the old key for at least 2 more hours Copyright © by IPexpert. All rights reserved.
41
6. When the backup switch is active and the primary switch comes back online after a reboot. Ensure that it will take back the active role after the switch is up for 3 minutes 7. Give this process a name of “IPexpertVLAN111” 8. A switch should declare it’s neighbor down within 1 second 9. When one of the Ethernet uplinks fails the priority should be lowered with 1/10th of the configured priority value 10. When a second Ethernet uplink fails the switch should stop forwarding Layer 3 traffic and send traffic across the vPC peer-‐link 11. The default gateway MAC address should be the MAC address of one of the physical Ethernet interfaces Task 6: VRRP 1. Ensure that hosts on VLAN 121 are always able to reach their default gateway, when one of the 2 switches fails 2. Use a standards based protocol for this use, which uses a single active default gateway 3.

Ensure this host is allowed access. 11. Configure a SVI with IP address 198.18.50.1/24 in VLAN 50 on SW1. 12. Ensure that all traffic entering the VLAN interface is checked against the routing table to ensure that the switch knows the Destination IP address of the packet and it has a routing entry towards this network. A default route would also qualify for this check. Task 3: Access Control Lists 1. Use a protection on VLAN 50 of SW1 to protect it against denied traffic according to the following rules. 2. Be as specific as possible. 3. The 198.18.255.100 host is allowed to access hosts in VLAN 50. Copyright © by IPexpert. All rights reserved.
74
4. Secure Web traffic coming from servers in 198.18.128.0/18 to VLAN 50 is allowed. Clients in VLAN 50 are using non-reserved ports. 5. The Server farm is located in the 198.19.0.0/16 subnet and the
198.18.192.0/24 subnet. Hosts in VLAN 50 want to access Web servers, DNS servers and Mail (to receive mail through POP3 and send mail) servers. You are prohibited to configure these applications in the ACL. Only two entries in the ACL are allowed for this question. 6. You are not allowed to apply the ACL to the VLAN interface 7. A host connected in VLAN 50 through interface Ethernet1/15 on SW2 is not allowed to access the IMAP server with IP address 198.19.0.25. Ensure this is enforced. 8. A rogue device is found that tries to log-‐in to management interfaces. Deny telnet and SSH traffic to the management interface of the switches from the 192.0.2.0/24 subnet. Ensure all other IP address are still able to manage the switches through all management services. Only a single ACL entry is allowed for this task. 9. Ensure all
TCP traffic entering on Ethernet3/22 on SW1 is copied to Ethernet3/23 on SW1 10. In addition to the IP security of VLAN 50 your manager also wants to only allow valid MAC addresses from the Server farm to access hosts in VLAN 50. The servers have MAC addresses in the range of 0bad.c0ff.ee00 up to 0bad.c0ff.eeff. 11. Statistics should be collected per entry in VLAN 50 12. Ensure the control plane of SW2 and SW3 is optimized for Layer 3 routing Task 4: AAA services Always group configurations for AAA servers There is a RADIUS server in the management network with IP address 172.16.100.201 The TACACS+ server in this network is 172.16.100.202 Both AAA servers are using a key of “IPexpertAAA” Declare the RADIUS server dead after 22 minutes. Check if the RADIUS server is working every 2 minutes. Use a username of “ipexpert” and a password of “IPexpert123” for this task Requests to AAA servers should timeout after 2 seconds On SW2 configure default authentication to be done by the RADIUS server Copyright © by IPexpert. All rights reserved.
75
SW2 should perform a fall-back to local user database in case the RADIUS server does not respond. For access to the console port only the local user database should be used On SW3 a Cisco proprietary protocol should be used for authenticating SSH users. When users do not have a role assigned, they should not be able to log-‐in to the switch. Users that try to log-‐in shout be notified when AAA servers are unreachable Use the strongest encryption for the local username/password database available and ensure that existing passwords are converted Ensure accounting is enabled on SW2 The TACACS+ users are configured with IOS-‐style privilege levels. Ensure SW3 honors these. SW2 should require local user entries to use strong passwords. SW3 does not enforce this. Create a user on SW3 with your first name as username which expires on December 31st of this year. Task 5: 802.1X 1. Hosts that want to access SW1 are required to authenticate. Hosts are connected at interfaces Ethernet3/25 up to 3/31 2. Users should be authenticated by the RADIUS server 3. On Ethernet3/26 and Ethernet3/27 it should be possible to have multiple hosts connected 4. After an hour the authentication should be re-‐checked against the RADIUS server for all interfaces participating in the authentication. You are not allowed to use global configuration commands for this task. 5. Interface Ethernet3/31 has a printer connected that has no software to support this authentication. Ensure the interface is still authenticated against the RADIUS server. 6. The switch should allow up to 4 authentication attempts before denying access 7. Ensure all activity on the switch is logged with the RADIUS server Copyright © by IPexpert. All rights reserved.
76
Task 6: Cisco TrustSec 1. Ensure all switches authenticate each other in the network 2. Ensure Cisco TrustSec is using RADIUS for authentication 3. Enable Cisco TrustSec on the 802.1X interfaces from Task 5 4. SW1 should authenticate itself with a password of “SW1p@ssw0rd” 5. SW2 should authenticate itself with a password of “SW2p@ssw0rd” 6. SW3 should authenticate itself with a password of “P@ssw0rdSW3” 7. Ensure switches authenticate each other without using the RADIUS server for exchanging SGT’s. 8. You are allowed to use a SVI on each switch in VLAN 99 with the IP subnet of 198.18.99.0/24 9. Leave all configuration in place on the switches when continuing with the next chapter.
