Verifying the Member ID, Role, and Neighbor Member Connections of a Virtual Chassis Member
Purpose
You can designate the role that a member performs within a Virtual Chassis or you can allow the role to be assigned by default. You can designate the member ID that is assigned to a specific switch by creating a permanent association between the switch’s serial number and a member ID, using a preprovisioned configuration. Or you can let the member ID be assigned by the primary, based on the sequence in which the member switch is powered on and on which member IDs are currently available.
The role and member ID of the member switch are displayed on
the front-panel LCD (for switches that have an LCD) or in the output
from the show virtual-chassis CLI command.
Each member switch can be cabled to one or two other member switches, using either the dedicated Virtual Chassis ports (VCPs) on the rear panel, an uplink port that has been configured as a VCP, or an optical port that has been configured as a VCP. The members that are cabled together are considered neighbor members.
Action
To display the role and member ID assignments using the CLI:
user@switch> show virtual-chassis
Virtual Chassis ID: 0000.e255.00e0
Mastership Neighbor List
Member ID Status Serial No Model Priority Role ID, Interface
0 (FPC 0) Prsnt abc123 ex4200-48p 255 Master* 1 vcp-0
2 vcp-1
1 (FPC 1) Prsnt def456 ex4200-24t 255 Backup 2 vcp-0
0 vcp-1
2 (FPC 2) Prsnt abd231 ex4200-24p 128 Linecard 0 vcp-0
1 vcp-1
Meaning
This output verifies that three EX4200 switches have been interconnected as a Virtual Chassis configuration through their dedicated VCPs to create an EX4200 Virtual Chassis. The display shows which of the VCPs is connected to which neighbor. The first port (vcp-0) of member 0 is connected to member 1 and the second port of member 0 (vcp-1) is connected to member 2. The FPC slots for the switches are the same as the member IDs.
The Mastership Priority values indicate that the primary and backup members have been explicitly configured, because they are not using the default value (128).
This example uses output from an EX4200 Virtual Chassis. The output, with the exception of the Model column, would be identical on all other Virtual Chassis.
