Verifying That Virtual Chassis Ports Are Operational


Display the status of Virtual Chassis ports (VCPs) in a Virtual Chassis or Virtual Chassis Fabric (VCF).


VCPs are not displayed when you issue the show interfaces command.


Display the VCPs:


The dedicated VCPs are displayed as vcp-0 and vcp-1. The uplink interfaces that have been set as uplink VCPs are displayed as 1/0, 1/1, 1/2, and 1/3. The network interfaces that have been set as VCPs are displayed as 0/20 and 0/21. The neighbor interface names of uplink and network VCPs are of the form vcp-255/pic/port—for example, vcp-255/1/0. In that name, vcp-255 indicates that the interface is a VCP, 1 is the uplink PIC number, and 0 is the port number. The fpc number is the same as the member ID. The trunk ID is a positive number ID assigned to the link aggregation group (LAG) formed by the Virtual Chassis. If no LAG is formed, the value is –1.


This example uses output from an EX4200 Virtual Chassis. The output is similar on all other types of Virtual Chassis or for a VCF.
