No switchport allowed on cisco 7609

[shimulshah1]

hi Guys,

I am trying to do a "no switchport" on cisco 7609 router but it keeps rejecting the command.

lab01(config-if)#no switchport 
Command rejected: not allowed on this interface.

Interface config -

sh run int te2/0/1
Building configuration...

Current configuration : 81 bytes
!
interface TenGigabitEthernet2/0/1
 switchport
 shutdown
 no mls qos trust
end

This was a routed port before but during troubleshooting I configured it to switchport and now I can't seem to take that off

Any help?

Try doing this:

conf t

default interface tengig2/0/1

(wait for a few seconds)

interface tengig2/0/1

no switchport

run the command in global configuration mode

Yeap! Just what francis said as well, ip routing needs to be enabled :D

[shimulshah1]

Yeah it was. All the interfaces are routed :)

[francis08]

sorry, before you run that command you have to run ip routing command at global congig mode. then on interface mode run no switchport command.

thanks guys for you replies. 

There is cisco bug CSCsk22554 related to this issue. 

I reloaded the router which fixed it as recommended by cisco TAC

should have tried default interface first! 

thanks
