Chapter 2 Configuring Basic Interface Parameters Configuring the Basic Interface Parameters Send document comments to [email protected] DETAILED STEPS Step 1 Command configure terminal Step 2 Example: switch# config terminal switch(config)# interface ethernet slot/port Step 3 Example: switch(config)# interface ethernet 3/1 switch(config-if)# flowcontrol {send | receive} {desired | on | off} Example: switch(config-if)# flowcontrol send on switch(config)-if# Step 4 show interface ethernet slot/port Step 5 Example: switch(config)# show interface ethernet 3/1 switch(config) show interface flowcontrol Step 6 Example: switch(config)# show interface flowcontrol switch(config) exit Step 7 Example: switch(config-if)# exit switch(config)# copy running-config startup-config Example: switch(config)# copy running-config startup-config Purpose Enters configuration mode. Specifies an Ethernet interface to configure by its slot number and port number, and enters the interface configuration mode. Specifies the flow-control setting for ports. You can set the send setting for only the ports running at 1000 Mb/s or faster. You can set the receive setting for ports running at any speed. Displays the interface status, which include the flow control parameters. Displays the flow control status for all Ethernet ports. Exits the interface mode. (Optional) Copies the running configuration to the startup configuration. This example shows how to set Ethernet port 3/1 to send flow control pause frames: switch# configure terminal switch(config)# interface ethernet 3/1 switch(config-if)# flowcontrol send on switch(config-if)# Configuring the MTU Size You can configure the maximum transmission unit (MTU) size for Layer 2 and Layer 3 Ethernet interfaces. For Layer 3 interfaces, you can configure the MTU to be between 576 and 9216 bytes (even values are required). For Layer 2 interfaces, you can configure the MTU to be either the system default MTU (1500 bytes) or the system jumbo MTU size (which has the default size of 9216 bytes).
