Chapter 2
Configuring Basic Interface Parameters
Configuring the Basic Interface Parameters
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.
SUMMARY STEPS
1.
configure terminal
2.
system jumbomtu
size
3.
show running-config all
4.
interface
type slot/port
5.
mtu
size
6.
exit
7.
copy running-config startup-config
Step 3
{
switchport
|
no switchport
}
Example:
switch(config-if)# no switchport
switch(config-if)#
Specifies to use Layer 2 or Layer 3.
Step 4
mtu
size
Example:
switch(config-if)# mtu 9216
switch(config-if)#
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.
Step 5
show interface ethernet
slot/port
Example:
switch(config)# show interface ethernet 2/1
Displays the interface status, which
includes the MTU size.
Step 6
exit
Example:
switch(config-if)# exit
switch(config)#
Exits the interface mode.
Step 7
copy running-config startup-config
Example:
switch(config)# copy running-config startup-config
(Optional) Copies the running
configuration to the startup configuration.
