Identifying vlan usage on a trunk

ciscoprolin

Level 1

Dear All,

we have 2 Switches where (because of a bad documentation) we're not sure if we can delete vlans xxx and yyy. No port on these Switches has

these vlans assigned but they are still on the trunk and NOT pruned and jt could well be that these Switches serve as a link of these vlans xxx and yyy from A to B. 

Therefore, we wonder if and how it is possible to identify if traffic is still propagated accross certain vlans on a trunk ?

 

Thanks very much for your help,

Thorsten
