I have installed a Catalyst 2960-S and a 3750-X-12S and I am trying to setup a VLAN 51 for some VoIP phones. I have added the VLAN as an interface on both switches, but the 3750 is not showing VLAN 51 as active when i do a show vlan. Also, it omitts showing Gi1/0/1 & Gi1/0/3 which are uplinks to 2960-S switches plugged in and working on VLAN1.
