I read that the PA-GE module on the 7200 supports an mtu of >1500.  I'm trying to set mine to 1546, but cannot.  What command do I enter to enable support for this size?


EDR01#config t

Enter configuration commands, one per line.  End with CNTL/Z.

EDR01(config)#int gig 5/0

EDR01(config-if)#ip mtu 1546

                                 ^

% Invalid input detected at '^' marker.

EDR01 (config-if)#ip mtu ?

  <68-1500>  MTU (bytes)

Hello David,

it is also a question of IOS image


also you need first to increase mtu with mtu command then you may be able to increase ip mtu


Hope to help
