Switch trunk ports
Posted on 2010-11-10
I have a couple of Cisco 3750's in a cross stack configuration. I have a couple of VLAN on these switches. Most ports are going to storage in a LACP config. I have older Foundry 4802-POE's that run to the IP phones and the client machines connect through the back of the IP phones.
What I want to do is connect 2 ports (g1/0/12, g2/0/12) to the gig uplink port on two of the 4802's. The uplink I want to share with VLAN 16 on the CISCO side. That way if I lose one 3750, I still have access.
From a L2 perspective, how do I do this?
