Excluded VLAN on Trunk

Saman Shamim

looking  at the picture, If I do the pruning and exclude VLAN 30 from allowed  VLAN list but allow every other vlans on Trunk port (g1) on switch B  because I don’t have any other VLAN 30 members anywhere in my network,  does this affect VLAN 30’s inter-vlan routing and/or internet  connection?

In other word, what does the switch do in terms of tagging frames when

1. receives an inter-vlan frame

2. receives internet frame

By the way am I following a correct logic ine the following? :

There is not any other VLAN 30 members in my network except these access ports on my switch B. So I would allow every VLANs on its g1 trunk port except VLAN 30 by using the following command:

switchport trunk allowed vlan 10,20,40

Hey Saman,

I believe you are asking about vlan autostate. Take a look at this:

It may answer your question... otherwise please get back to the forum with more information about vlan 30.

Cheers,

Fabio
