Cisco 3750X

Sean McCoy

I have two 3750X stacks at an elementary school. They are linked via 1GB fiber uplink. I have a VLAN that decided to stop working. I moved all access ports to another VLAN and they are fine. One stack is in VTP server mode and the other transparent. Switches can communicate with each other. Problem seems to be isolated to that particular VLAN but I can't figure out what it is.
