Chapter 2 Configuring Basic Interface Parameters Configuring the Basic Interface Parameters Send document comments to [email protected] Step 3 Command {switchport | no switchport} Purpose Specifies to use Layer 2 or Layer 3. Step 4 Example: switch(config-if)# no switchport switch(config-if)# mtu size Example: switch(config-if)# mtu 9216 switch(config-if)# Step 5 show interface ethernet slot/port Step 6 Example: switch(config)# show interface ethernet 2/1 exit For a Layer 2 interface, specifies either the default MTU size (1500) or the system jumbo MTU size (9216 unless you have changed the system jumbo MTU size). For a Layer 3 interface, specifies any even number between 576 and 9216. Displays the interface status, which includes the MTU size. Exits the interface mode. Step 7 Example: switch(config-if)# exit switch(config)# copy running-config startup-config (Optional) Copies the running Example: configuration to the startup configuration. switch(config)# copy running-config startup-config This example shows how to configure the Layer 2 Ethernet port 3/1 with the default MTU size (1500): switch# configure terminal switch(config)# interface ethernet 3/1 switch(config-if)# switchport switch(config-if)# mtu 1500 switch(config-if)# Configuring the System Jumbo MTU Size You can configure the system jumbo MTU size, which can be used to specify the MTU size for Layer 2 interfaces. You can specify an even number between 1500 and 9216. If you do not configure the system jumbo MTU size, it defaults to 9216 bytes.
