If the VLAN name is longer than 15 characters, traffic originating from the debug-sidecar will not work correctly and can cause issues with troubleshooting.
Traffic that originates from the debug sidecar will not work correctly. For example, if an internal VLAN is configured with a long name, the name in the output from 'ip addr' and 'ip route' on the debug sidecar will show a truncated name. Additionally, if a ping is attempted to a destination that is connected using this VLAN, the ping packets will be dropped and ping will fail.
The user creates an L1 network with a VLAN that has a name longer than 15 characters.
Use VLAN names less than 16 characters long.
