Cisco: Native VLANs

[Badgerpoo]

Probably not a suitable place to ask, but thought I'd give it a shot!

Can anyone think of why when two ends of a link have a native vlan mismatch (halfway through changing the native vlan) the connection should drop? I would have thought only the management interface would go down but the entire switch loses it's connection in this case. I have already configured 400 switches this way until this one, whose configuration is not abnormal.

Any ideas?

Yeah the allowed vlan is a range excluding the new native vlan but including the old, is that a problem?

I thought the Native VLAN only related to management, the access vlans used on the switch where allowed anyway so that shouldn't change. I'll paste the relevan lines of config tomorrow to give you a better idea but it fits in with your bizarre scenario
