Configuring the Ethernet SPAs
Command
Router(config-if)# mtu bytes
To return to the default MTU size, use the no form of the command.
Verifying the MTU Size
To verify the MTU size for an interface, use the show interfaces gigabitethernet privileged EXEC command
and observe the value shown in the "MTU" field.
The following example shows an MTU size of 1500 bytes for interface port 1 (the second port) on the Gigabit
Ethernet SPA installed in the top subslot (0) of the SIP that is located in slot 2 of the Cisco ASR 1000 Series
Routers:
Router# show interfaces gigabitethernet 2/0/1
