[c-nsp] NATIVE_VLAN_MISMATCH

[Yuri Bank]

Well, you said the 3550 has had its nvram erased and is running a default
config, so all of its switch ports are in  vlan 1. I am guessing the other
switch has its port in a different vlan. Even if both ports are in access
mode, CDP will generate native vlan mismatches if their configured access
vlans are different.
