Token-Ring Interface Monitoring Commands

This section summarizes the Token-Ring monitoring commands. Enter commands at the TKR> monitoring prompt. Table 30 lists the monitoring commands.

Table 30. Token-Ring Monitoring Command Summary

CommandFunction

? (Help)

Displays all the commands available for this command level or lists

 

the options for speci®c commands (if available). See ªGetting Helpº

 

on page 10.

Dump

Displays a dump of the RIF cache.

0000C90B1A57

ON_RING

Yes

0220

MAC address

Displays the MAC address of the Token-Ring interface.

State Displays one of the interface states:

On_ring - indicates that a RIF was found for a node on the ring.

Have_route - indicates that a RIF was found for a node on a remote ring.

No_route - is displayed for a brief period of time as an explorer frame is sent out and the router is waiting for a return.

Discovering - indicates that the router sent an explorer frame to rediscover the RIF.

St_route - indicates that a route obtained from a Spanning tree explorer.

Usage Indicates that a RIF was used in a packet. The number is arbitrary and has no functional signi®cance.

RIF Displays a code that indicates the RIF in hexadecimal.

Note: The RIF is displayed only if Source Route Bridging is enabled on the

Token-Ring interface.

vNetBIOS RIF data can be displayed using the following sequence of commands: talk 5, protocol ASRT, name-caching, list cache rifs.

vData Link Switching RIF data can be displayed using the following sequence of commands: talk 5, protocol dlsw, list llc2 session all.
