Chapter 11 Configuring Interface Characteristics
Monitoring and Maintaining the Interfaces
If you enter a value that is outside the allowed range for the specific type of interface, the value is not
accepted.
Once the switch reloads, you can verify your settings by entering the show system mtu privileged EXEC
command.
This example shows how to set the maximum packet size for a Gigabit Ethernet port to 1800 bytes:
Switch(config)#
system jumbo mtu 1800
Switch(config)# exit
Switch# reload
This example shows the response when you try to set Gigabit Ethernet interfaces to an out-of-range
number:
Switch(config)# system mtu jumbo 25000

Monitoring and Maintaining the Interfaces
These sections contain interface monitoring and maintenance information:
• Monitoring Interface Status, page 11-29
•
Clearing and Resetting Interfaces and Counters, page 11-30
• Shutting Down and Restarting the Interface, page 11-30
Step 3
system mtu jumbo bytes (Optional) Change the MTU size for all Gigabit
Ethernet interfaces on the switch stack. The range is
1500 to 9000 bytes; the default is 1500 bytes.
Step 4
system mtu routing bytes (Optional) Change the system MTU for routed ports.
The range is 1500 to the system MTU value, the
maximum MTU that can be routed for all ports.
Although larger packets can be accepted, they cannot be
routed.
Step 5 end Return to privileged EXEC mode.
Step 6
copy running-config startup-config Save your entries in the configuration file.
Step 7 reload Reload the operating system.
