Modifying MTU Size on Port-Channel

Complete the following steps to modify MTU size on the port-channel interface:

Restrictions

If the MTU size of a port-channel member link is different from the MTU size of the port-channel interface, the member link is not bundled.

SUMMARY STEPS

1.enable

2.configure terminal

3.interface port-channel number

4.mtu bytes

DETAILED STEPS

	Command	Purpose
Step 1
	enable	Enables privileged EXEC mode.
		• Enter your password if prompted.
	Example:
	Router> enable
Step 2
	configure terminal	Enters global configuration mode.
	Example:
	Router# configure terminal
Step 3
	interface port-channel number	Selects a port-channel interface and enters interface
		configuration mode.
	Example:	• number—Specifies the port-channel interface
	Router(config)# interface port-channel 1	number. The range is from 1 to 8.
Step 4
	mtu bytes	Configures the MTU size for port-channel interface.
		• bytes—The range is from 1500 to 9216. The
	Example:	default is 9216.
	Router(config-if)# mtu 4000	Note To set the MTU size to its default value, use
		the no mtu or default mtu command.

Verifying the MTU Size on Port-Channel

To verify the MTU size on port-channel interface, use the show interface port-channelcommand.

Router# show interface port-channel 1

Port-channel1 is up, line protocol is up (connected)
