DETAILED STEPS
PurposeCommand or Action
Enters global configuration mode.configure terminal
Example:
Switch# configure terminal
Step 1
(Optional) Changes the MTU size for all Fast Ethernet interfaces on
the switch.
system mtu bytes
Example:
Switch(config)# system mtu 2500
Step 2
The range is 1500 to 1998 bytes; the default is 1500 bytes.
(Optional) Changes the MTU size for all Gigabit Ethernet and
10-Gigabit Ethernet interfaces on the switch or the switch stack.
system mtu jumbo bytes
Example:
Switch(config)# system mtu jumbo 7500
Step 3
The range is 1500 to 9198 bytes; the default is 1500 bytes.
(Optional) Changes the system MTU for routed ports. You can also
set the maximum MTU to be advertised by the routing protocols that
system mtu routing bytes
Example:
Switch(config)# system mtu routing 2000
Step 4
support the configured MTU size. The system routing MTU is the
maximum MTU for routed packets and is also the maximum MTU
that the switch advertises in routing updates for protocols such as
OSPF.
This command is not supported on switches running the
LAN base feature set.
Note
Returns to privileged EXEC mode.end
Example:
Switch(config)# end
Step 5
Saves your entries in the configuration file.copy running-config startup-config
