Well, I downgraded to the latest 12.4 (c7200-is-mz.124-25c.bin). Same symptoms. Any ideas? I tried removing the port-channel and re-adding too, no luck.

Greetings,

I just upgraded a Cisco 7206 NPE-400 to: c7200-advipservicesk9-mz.151-1.XB.bin from the latest 12.4. I've got a port channel and it removed the 'channel-group 1' line from the two ethernet interfaces. When I try to add them back I get:

router(config-if)#channel-group 1
Error: This interface does not allow user-settable mtu.
 Remove the mtu command from the port channel configuration
 to be able to add this interfaceto the port channel

I don't have any mtu commands on any interfaces except the defaults, which can't be removed. Here's the relevant config:

interface Port-channel1
 description << TO GI9/5 10/5 >>
 no ip address
 no ip redirects
 random-detect
!
interface Port-channel1.11
 encapsulation dot1Q 11
 ip address IP 255.255.255.0
 no ip redirects
 ip ospf authentication-key 7
 ip ospf cost 1
 ip ospf dead-interval minimal hello-multiplier 4
!
interface FastEthernet0/0
 description << TO 9/5 >>
 no ip address
 no ip redirects
 no ip unreachables
 duplex full
 random-detect
 no cdp enable
!
interface FastEthernet2/0
 description << TO 10/5 >>
 no ip address
 no ip redirects
 no ip unreachables
 duplex full
 no cdp enable
!

Any tips/help would be greatly appreciated.

Thanks,
Jason
