Cabletron Systems CSX1000 IPX Isolated Mode Background Information, Displaying WAN Peer List

USER’S GUIDE

IPX ISOLATED MODE BACKGROUND INFORMATION

When operating with isolated mode enabled, the CyberSWITCH does not relay IPX datagrams received from the WAN to other IPX routers/hosts located on the WAN. IPX datagrams received from the WAN will be discarded if they need to be forwarded over the WAN. IPX datagrams received on the LAN interface are forwarded to the proper interface.

IPX TRIGGERED RIP/SAP

IPX Triggered RIP/SAP is a type of broadcast protocol used over WAN circuits for router-to-router exchange of route and service information. Its broadcasts are “triggered” by events such as updates or changes to route and service tables. Triggered RIP/SAP offers an alternative to running periodic broadcasts over the WAN, and is especially useful when you consider the costs of periodic broadcasts over WAN links.

Triggered RIP and triggered SAP are user-configurable items which you enable in the on-node device database (page 293). Under the Options Menu, IPX Routing, Triggered RIP/SAP, you can display the devices already configured for these features (i.e., the WAN peer list), as well as configure global timers (applicable to the RIP or SAP update packets).

DISPLAYING WAN PEER LIST

1.Select Triggered RIP/SAP from IPX Routing Menu. A menu similar to the following will be displayed:

IPX Triggered RIP/SAP Configuration

1)WAN Peer List

2)Global Triggered RIP/SAP Timers

Select function from above or <RET> for previous menu:

2.Select WAN Peer List. The system displays the configured devices for which the triggered RIP/ SAP feature enabled. It also displays the WAN peer type as active or passive (page 296).

Keep in mind that you cannot make changes from this menu; you can only display information. To make changes to the WAN peer list, go to the Device Table Menu (page 292).
