I am currently working on my company's Data Center LAN. It is designed with all server access switches trunked to the (2) distribution switches. The access switches are a combination of CAT 6500s, WS-C2948G-GE-TX and WS-C2980G-A top-of-the-rack switches. All are running CAT OS.
Currently, vlan 1 is permitted on all uplinks/trunks. However, vlan 1 is only used when we disconnect a host, i.e. we return the port to vlan 1. Also, Vlan 1 does not have an active L3 interface on the distribution MSFC either.
Will it affect anything if I prune or clear vlan 1 off of every trunk/uplink within the server farm access layer??
Does CDP, VTP or other Cisco protocols need vlan 1 to inter-operate??
Thanks for you help,
