I will soon have a trunk configured with a metro provider so they can pass vlans from my customers to my network. I will be using a 3560E switch and want to know if I could enable a vlan interface without having to actually utilze a physical port to that vlan.
Right now if I do not assign a physical port to a vlan, the vlan interface show up but protocol is down. For some clients I do not need to use any physical ports as I am just routing traffic received on the trunk link to a different vlan on the same switch. So those vlans don't need to really use a physical port.
This should be possible to do right??
Thanks in advance.
the vlan interface will be in a up/up state automatically or is there more to configure then that?
As long as you don't prune that Vlan on the trunk, it should work as I described.
