Verifying That Virtual Chassis Ports on an EX Series Switch Are Operational

Purpose

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

Note: The interfaces for VCPs are not displayed when you issue the show interfaces ge- command.

Action

Display the VCPs:

user@switch> show virtual-chassis vc-port all-members

Meaning

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.

Note: This example uses output from an EX4200 Virtual Chassis. The output would be identical on all other types of Virtual Chassis.
