I have a Cisco 2960-CX switch mounted in a Mobile CT (hospital owned). This "trailer" moves between my 7 campuses as needed. Is there a way for the switch to obtain an IP address dynamically, over a trunk link, connecting to a different management network/vlan# at each campus?
I can only seem to get it to work if I preconfigure the switch with the proper vlan #. I'd like for the local vlan # not to matter. I've tried using the "native vlan" option on the trunk, but I believe this only affects inbound packets.
My backup plan would be to preconfigure the switch with a local vlan # for EACH campus, and add all of them to the trunk ahead of time, using the "ip address dhcp" in each.
The reason I need the "trunk" is I need to pass 3 vlans out to this switch. One for a PC/Printer/access point, another for VoIP and a third for the CT (Layer 2 extended from the firewall).
