Hi, All.
I am trying to change the regular MTU value on a vlan interface. This is how the setup looks like. RSM running IOS ver 12.2(6a) in slot 4 on a catalyst 5500 switch. There is a vlan interface on RSM where I can sucessfully increase the tag-switching mtu , while changing the regular MTU size from 1522 to 1544 I get the following message
(config-if)#mtu 1544
% Interface Vlanxx does not support user settable mtu.
(config-if)#ip mtu 1544
% Invalid IP MTU specified; minimum 68, maximum 1500
(config-if)#ip mtu ?
<68-1000000> MTU (bytes).
I am having no luck in changing the MTU size with above commands. Can anyone help or shed some more light on chainging the regular MTU size.
Thanks,
Adnan

Try changing or setting the mtu for a particular vlan using the command,
set vlan

Thanks for you reply, the regular MTU vlaue that I am trying to change is for an interface that is on an RSM ( Route switch module )sitting on 5500.
