vcp-1 Dedicated Up
Meaning
The
show virtual-chassis vc-port all-members
command lists all the interfaces for the
Virtual Chassis configuration. In this case, no VCP uplinks have been configured. However,
the VCP interfaces are automatically configured and enabled when you interconnect
member switches using the dedicated Virtual Chassis ports. There are two dedicated
VCPs on the rear panel of each EX4200 switch. It is recommended that you interconnect
the member switches using both VCPs for redundancy. The VCP interfaces are identified
simply as
vcp-0
and
vcp-1
. The
fpc
number is the same as the member ID.
Troubleshooting
To troubleshoot the configuration of an expanded Virtual Chassis, perform these tasks:
Troubleshooting Mastership Priority
Problem
You want to designate a different member as the master.
Solution
Change the mastership priority value or values of the switches, designating the highest
mastership priority value for the switch that you want to be master.
1.
Lower the mastership priority of the existing master (member 0).
[edit virtual-chassis]
user@SWA-0#
set member 0 mastership-priority 1
2.
Set the mastership priority of the member that you want to be the master to the
highest possible value (255):
[edit virtual-chassis]
user@SWA-2#
set member 2 mastership-priority 255
Troubleshooting Nonoperational VCPs
Problem
The VCP interface shows a status of
down
.
Solution
Check the cable to make sure that it is properly and securely connected to the VCPs.

Example: Setting Up a Multimember Virtual Chassis Access Switch with a Default
Configuration
You can configure a multimember Virtual Chassis access switch in a single wiring closet
without setting any parameters—by simply cabling the switches together, using the
dedicated Virtual Chassis ports (VCPs). You do not need to modify the default
