If there is an error code you can’t fix, let us assist you in our monthly FixIT column. This month, we’re focusing on troubleshooting network interfaces on Juniper EX-Series Virtual Chassis.
Problem:
Gigabit Ethernet interfaces retain their previous slot numbers when a member switch is disconnected from the Virtual Chassis.
Solution:
If a switch had been previously connected as a member of a Virtual Chassis configuration, it retains the member ID that it was assigned by being a member of that configuration even after it got disconnected and started operating as a standalone switch. The interfaces that were configured while the switch was a member of the Virtual Chassis configuration retain the old member ID as the first digit of the interface name.
For example, if the switch was previously member 1, its interfaces are named ge-1/0/0 and so on.
To change the switch member ID so that its member ID is 0, and to rename the switch interfaces, follow the steps below:
1. To change the member ID to “0”:
user@switch> request virtual-chassis renumber member-id 1 new-member-id 0
2. To rename the interfaces to match the new member ID:
user@switch# replace pattern ge-1/ with ge-0/
