show interfaces tokenring
show interfaces tokenring
When troubleshooting Token Ring media in a Cisco router environment, you can use the show
interfaces tokenring command to provide several key fields of information that can assist in
isolating problems. This section provides a detailed description of the show interfaces tokenring
command and the information it provides in Table 6-2.
Use the show interfaces tokenring privileged exec command to display information about the Token
Ring interface and the state of source route bridging:
show interfaces tokenring unit [accounting]
show interfaces tokenring slot | port [accounting] (for the Cisco 7500 series and Cisco 7200
series)
show interfaces tokenring [slot | port-adapter | port] (for ports on VIP cards in the Cisco 7500
series routers)
Syntax Description
• unit—Must match the interface port line number.
• accounting—(Optional) Displays the number of packets of each protocol type that have been
sent through the interface.
• slot—Refers to the appropriate hardware manual for slot and port information.
• port—Refers to the appropriate hardware manual for slot and port information.
• port-adapter—Refers to the appropriate hardware manual for information about port adapter
compatibility.
Command Mode
Privileged exec
Usage Guidelines
This command first appeared in Cisco IOS Release 10.0.
The command description was modified in Cisco IOS Release 11.3 to account for support on new
full-duplex Token Ring port adapters.
If you do not provide values for the parameters slot and port, the command will display statistics for
all the network interfaces. The optional keyword accounting displays the number of packets of each
protocol type that have been sent through the interface.

conflict Step 1 Use the no lnm rps interface configuration command to disable the RPS function on
the router that you are trying to insert into the ring.
Step 2 Try to insert the router into the ring.
Step 3 If you can insert the router with RPS disabled, there is a conflict between RPS
implementations. Contact your technical support representative for more information.
