I am in the process of setting up a trunk port for a client. I want to allow only 4 production vlan to traverse the trunk. The rest of the vlans I want to prune off.
I am shipping this trunk port to an IPS unit to inspect the traffic for mal content. The IPS interface is supposed to act as a trunk port as well and then ship traffic from one vlan pair back to another Vlan Pair. I am configuring two vlan pairs on the interface of the IPS unit.
Yesterday i used the command " swi trunk pruning vlan 4,6,7,8,10,14,15,20"
Should this command keep these vlan's from propogating down the trunk link?
As Brandon indicated, switchport trunk pruning vlan command works in conjunction with having VTP Pruning enabled in the VTP domain. VTP Pruning must be enabled in the VTP server and this change will be propagated throughout all switches in the same domain.
If you want to go with manual pruning on a inter-switch link, then I recommend using the command switchport trunk allowed vlan instead.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
