Troubleshooting the Virtual Chassis
To troubleshoot the configuration of a Virtual Chassis, perform these tasks:
Troubleshooting the Assignment of Roles
Problem The master and backup roles are not assigned to the member switches that you want
to function in these roles.
Solution Modify the mastership priority values.
To quickly modify the mastership priority of SWA-1 (member ID 1), copy the following
command and paste it into the switch terminal window:
[edit virtual-chassis]
user@SWA-1#
set member 1 mastership-priority 255
Troubleshooting the VCPs
Problem The VCPs are down.
Solution Check to make sure that you have cabled the appropriate ports.
1.
2.
Check to make sure that the cables are seated properly.
You should generally cable and interconnect both of the VCPs on the member switches,
for redundancy and high availability.
