Configuration Examples

Use to configure the MRU size for the interface.
Specify a value in the range 4–9996 bytes.
Coordinate this value with the network administrator on the other end of the line.
If you set this value with a different value for another protocol, such as IP, the router
uses the lower value. The lower MRU might cause unexpected results in the network.
Example
host1(config-if)#mru 1500
Use the no version to restore the default, 1600 bytes.
See mru.
Use to configure the MTU size for the interface.
Specify a value in the range 4–9996 bytes.
You should coordinate this value with the network administrator on the other end of
the line.
You can set a different MTU value in higher-level protocols, such as IP. If you do, the
router uses the lower value. The lower MTU might cause unexpected results in the
network.
Example
host1(config-if)#mtu 1500
Use the no version to restore the default, 1600 bytes.
See mtu.
Use to assign a text description or an alias to a serial HDLC interface.
You can use this command to help you identify the interface and keep track of interface
connections.
The description or alias can be a maximum of 80 characters.
Use "show interfaces serial" on page 165 to display the text description.
Example
host1(config-if)#serial description ottawa012 hdlc channel
Use the no version to remove the text description or alias.
See serial description.
This section provides some configuration examples to illustrate how to use the CLI
commands.
