I have been implementing a new Cisco 3560 this morning. The switch is setup using OSPF and connectd to a Cisco 3550 over a VLAN interface.
My question is - i have 12 other VLANs and VLAN interfaces on the switch. None of these come 'up' unless there is an active device in the VLAN. Is this correct? I usually configure one VLAN as a management VLAN and assign that an IP address, but i can't even get to that unless i put a device in the VLAN.
The 3560 itself can see all other routes in the network when i do Show Ip Route OSPF, and the OSPF adjacency is fine, but i cannot get back to any of the VLAN interfaces on the switch unless i plug a device into each VLAN...
Any help much appreciated, can post configs if this helps,
