Hello and happy new year for all,
we have more than hundred 2950 cisco switch and some 3550, in the plan, without vtp prunning.
On trunk, i have allowed only some vlan. My question is : Can the command "switchport trunk allow vlan except 7,15" be make on distribution switch only (and then, the access switch become root for vlan 7 and 15 because the trunk is configured to pass all vlan in his configuration) ?
Is it a good situation for the network ?
I ask the question because of the working to configure all distribution switch AND access switch with the same command.
