DETAILED STEPS
Command
Step 1
configure terminal
Example:
switch# config terminal
switch(config)#
Step 2
interface ethernet slot/port
Example:
switch(config)# interface ethernet 3/1
switch(config-if)#
Step 3
flowcontrol {send | receive} {desired | on | off}
Example:
switch(config-if)# flowcontrol send on
switch(config)-if#
Step 4
show interface ethernet slot/port
Example:
switch(config)# show interface ethernet 3/1
switch(config)
Step 5
show interface flowcontrol
Example:
switch(config)# show interface flowcontrol
switch(config)
Step 6
exit
Example:
switch(config-if)# exit
switch(config)#
Step 7
copy running-config startup-config
Example:
switch(config)# copy running-config startup-config
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).

Configuring the Basic Interface Parameters
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.
