Chapter 35 Configuring Layer 3 Interfaces
Configuring VLANs as Layer 3 Interfaces
This example shows how to apply SVI Autostate Exclude on interface g3/1:
Switch# conf terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# interface g3/1
Switch(config-if)# switchport autostate exclude
Switch(config-if)# end
Switch# show run int g3/4

Configuring IP MTU Sizes
You can set the protocol-specific maximum transmission unit (MTU) size of IPv4 or IPv6 packets that
are sent on an interface.
For information on MTU limitations, refer to “Maximum Transmission Units” on page 35.
Step 5
Switch# show run interface
Displays the running configuration.
Step 6
Switch# show interface switchport
Verifies the configuration.
