On a campus-area switched LAN with multiple 2950's connected to a Cat4K at the core via media converters/fiber, several of the 2950's are accumulating errors (> 100 per min) on the VLAN virtual interface (used for switch management and monitoring). None of the physical ports (at the 2950s or the 4K) show any errors. Trunking protocol is 802.1q.

Hi Mike, I might have missed seeing it in the configs but.....If you are not using a vlan 1 and have shut it down, you stil need to define a 'native vlan'. This may be vlan103. On the trunk port try this "switchport trunk native vlan 103".
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
