Hello
I’ve spotted a funny behaviour on cisco ios when doing vtp pruning with except keyword.
If you don’t want to prune e.g vlan 5, you think it’d suffice to say:
SW1(config)# int fa0/19
SW1(config-if-range)#switchport trunk pruning vlan except 5
% Range command terminated because it failed on FastEthernet0/19
Solution: you need to hardcode not pruning vlans 1 and 1002-1005…
SW1(config-if-range)#switchport trunk pruning vlan except 1,5,1002-1005
SW1(config-if-range)# !!! SUCCESS!!!
