I need help for some weird pb.
When trying to configure a port of 6500 as a layer 2 port (on 6148A-GE-TX module) by entering the "switchport" command, the switch rejects the command with "not a switching port" as error message !
About half of the card ports are already configured as switching ports, the others are not used (so shutdown and routed by default)
I have tried on another 6500 (same card, same ios version) without any problem.
IOS version : 12.2(33)SXH3A modular (IPbaseK9)
Thanks for your help
