can let the member ID be assigned by the master, 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.
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 module port that
has been configured as a VCP, or an SFP network port on an EX4200-24F switch that
has been configured as a VCP. The members that are cabled together are considered
neighbor members.
To display the role and member ID assignments using the CLI, use the
status command:
user@SWA-0> show virtual-chassis status
Virtual Chassis ID: 0000.e255.00e0
Member ID Status Serial No
0 (FPC 0) Prsnt abc123
1 (FPC 1) Prsnt def456
2 (FPC 2) Prsnt abd231
This output verifies that three EX4200 switches have been interconnected as a Virtual
Chassis configuration using their dedicated VCPs . The display shows which of the VCPs
is connected to which neighbor. The first port (
member and the second port of member

slots for EX Series switches are the same as the member IDs.
