I'm getting this error message when tryingto configure a port as a trunk:
Command rejected: Conflict with port based features
The interface I am trying to configure is 6/24 it had been defaulted out and the configuration is blank. When I try and make it a trunk port I get the above error.
My other ports hare configured as below:
interface GigabitEthernet6/23

Apparently this is a known bug with Cisco CSCul08799
IPDT: nmsp prevents converting the port from access to trunk
CSCul08799
Description
Symptom:
"nmsp enable" doesn't allow the port to be converted from access to trunk. Even when "nmsp attachment suppress" is configured on the interface, nmsp is not ignored on the interface
Conditions:
"nmsp enable" or "nmsp attachment suppress" under the interface
Workaround:
disable nmsp and default the interface to configure the port as trunk
This required a reboot as well after I executed the commands and rebooted things worked great...
