Cisco IOS Voice, Video, Fax Command Reference
show vrm vdevices
To display detailed information for a specific digital signal processor (DSP) or a brief summary display
for all voice feature cards (VFCs), use the show vrm vdevices command in privileged EXEC mode.
show vrm vdevices {{vfc-slot-number | voice-device-number} | summary}
Syntax Description
Defaults No default behavior or values.
Command Modes Privileged EXEC
Command History
Usage Guidelines Use the show vrm vdevices command to display detailed information for a specific DSP or a brief
summary display for all VFCs. The display provides information on the number of channels, channels
per DSP, bitmap of DSPMs, version numbers, and so on. This information is useful in monitoring the
current state of your VFCs.
The display for a specific DSP provides information on the codec that each channel is using, if active,
or last used and if the channel is not currently sending cells. It also displays the state of the resource. In
most cases, if there is an active call on that channel, the resource should be marked active. If the resource
is marked as reset or bad, this may be an indication of a response loss for the VFC on a reset request. If
this condition persists, you might experience a problem with the communication link between the router
shelf and the VFC.
Examples The following is sample output from the show vrm vdevices command specifying dial shelf slot number
and DSP number. In this particular example, the call is active so the statistics displayed are for this active
call. If no calls are currently active on the device, the statistics would be for the previous (or last active)
call.
