Keep this in mind when using a Distributed Analyzer on the other side of a WAN link. (Avoid slow WAN link) • Communication between DPI/GPI with PI uses RSP (Remote Service Protocol) over IP - can be encrypted 24 Presentation Presenter Date Company Confidential Setting up DPI/GPI or 69X • HELP for a list of the command • Remember to reboot to use the setting: set syshwreset warm 69X only Command list found in Quick Start Guide 25 Presentation Presenter Date Company Confidential PI directly link to DPI VT-100 Terminal Emulator > PCMCIA Adapter Crossover Cable Management Port …. ….. …… .…… .…… .…… ……. ….… .…… ….… ……. …….
