I can't use vlan port assignment. When I try to change a port, I've the folling error:
There were some erros during operation.
Error occured moving port... into vlan index ...
Cause: Timeout occured while performing SNMP operation.
Action Verify the following:
Device is reachable using ping
Verify that DCR is configured with correct SNMP credentials for the device
I'm sure both are OK.
