This appears to be the case. I tested as you did below on a lab 3750ME, and got the same error. Along similar lines, I investigated to see whether it was possible to manually assign a VLAN id to the lo1 interface, but there does not seem to be any switchport or vlan-related commands available on that if: gw.snrtcamn(config)#int loopback 1 gw.snrtcamn(config-if)#?
