hello Expert,

I recently reconfigured all my router from frame-relay to use ip dedicated .
While i was using frame-relay i was using the show pvc  command to gather stats about line status etc.
I would like to know if  there is any command similar to show pvc in ip dedicated that can provide same line status etc.

Regards

If your serial interface loses connection to the telco I would expect it to generate messages in syslog that show it going down and then coming back up again. Here is an example of the messages that were generated on a router when the serial interface lost connection.

021663: *Oct 26 18:36:33 MDT: %CONTROLLER-5-UPDOWN: Controller T1 0/2/3, changed state to down (AIS detected)
021664: *Oct 26 18:36:35 MDT: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/2/3:1, changed state to down
021665: *Oct 26 18:36:35 MDT: %LINK-3-UPDOWN: Interface Serial0/2/3:1, changed state to down
021666: *Oct 26 18:36:37 MDT: %CONTROLLER-5-UPDOWN: Controller T1 0/2/3, changed state to up
021667: *Oct 26 18:36:39 MDT: %LINK-3-UPDOWN: Interface Serial0/2/3:1, changed state to up
021668: *Oct 26 18:36:49 MDT: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/2/3:1, changed state to up

I found these using the show log command. Assuming that logging was correctly configured on your router I would expect that it would generate messages that were somewhat similar.

Using Frame Relay on the serial interface provides a signaling capability and the ability to provide separate logical connections over the serial interface. The show pvc provided information derived from the signaling communication from the Frame Relay switch. If you change the serial interface to use HDLC or PPP then there is no logical subdivision of the line and no signaling to a network switch managing the line, and so no command quite like show pvc. For line statistics you can use the show interface command.
