Description

This article provides information on how to view the diagnostic detail (DOM) for the transceiver on the 10G/1G VC port.

Symptoms

You can configure the virtual chassis with the 10G/1G VC ports on certain EX switches that support the virtual chassis. At times, you may need to view the diagnostic detail for troubleshooting purposes.

If the virtual chassis is configured with xe-0/1/0 and xe-1/1/0 , as shown below, you will not check the diagnostics via the show interfaces diagnostics optics xe-0/1/0 command: 

lab@EX3300# run show virtual-chassis vc-port
fpc0:
--------------------------------------------------------------------------
Interface Type Trunk Status Speed Neighbor
or ID (mbps) ID Interface
PIC / Port
1/0 Configured -1 Up 10000 1 vcp-255/1/0

fpc1:
--------------------------------------------------------------------------
Interface Type Trunk Status Speed Neighbor
or ID (mbps) ID Interface
PIC / Port
1/0 Configured -1 Up 10000 0 vcp-255/1/0


lab@EX3300# run show interfaces diagnostics optics xe-0/1/0
Note : The above command does not show anything.

Solution

 

EX3300, EX4200 and EX4500 devices, which are running on 12.2 or later, support the viewing of the diagnostics detail for the 10G/1G VC ports via the following command: 

lab@EX3300> show virtual-chassis vc-port diagnostics optics
