I have a question concerning a Cat 3750.
Presently, I have a couple VLAN's configured on this LAN switch. We only have 1 user on the switch (planned for many more). I have the following VLAN's configured:
VLAN 200 managment
VLAN 201 User VLAN
I have an up link to an aggregation switch via a layer 3 PO (PO3)
My problem is this.
If the single user removes his desktop from the switch, the VLAN Interface goes into an Up / Down state until such time as a host is plugged back into the switch.
any thought on why this would be?
