[c-nsp] 7200 - G1 PortChan MTU

[CiscoNSP List]

Hi,

Have a G1, with one active Gig port in a portchan (Second member is currently disconnected, but is also a Gig port on the G1) - No other ports are configured as member ports.

Gi0/1 (Active member) has an mtu of 1998 - Portchan doesnt have an mtu configured (So is defaulting to 1500)

Attempting to change the mtu on the portchan, I get the following:

(config)#interface Port-channel1(config-if)#mtu 1998               % At least one member of the channel group 1 is not a 2FE port adapter

Any suggestions why this is happening? 

And I assume the only way to resolve this is to default the member ints, re-add them to the portchan and then change the mtu on the portchan?

Cheers.
