Setting MTU on a 2851 serial I/F

[mitchell.smith]

Using WIC-1DSU-T1V2, is the MTU fixed or configurable? I cant find commands regarding this. Thanks, Mitchell

To set the maximum transmission unit (MTU) size of IP packets sent on an interface, use the ip mtu interface configuration command. To restore the default MTU size, use the no form of this command.

ip mtu bytes

no ip mtu

you can go into interface config mode under the interface whose MTU you want to configure and try above commands. If it allows you to configure, it means you can set MTU otherwise not.

hope it helps ... rate if it does ...

Hi,

What is the difference of the MTU value under

"sh int fa 0/0" and "sh ip int fa0/0"?
