Purpose
Controls the use of switching methods for forwarding IP packets.
• The cef keyword enables Cisco Express Forwarding operation on an
interface after Cisco Express Forwarding operation was disabled.
• The distributed keyword enables distributed switching on the interface.
Removes any specified IP address.
Enables keepalive packets and specifies the number of times that the Cisco
software tries to send keepalive packets without a response before bringing
down the interface or before bringing the tunnel protocol down for a specific
interface.
• The period argument is an integer value, in seconds, greater than 0. The
default is 10.
• The retries argument specifies the number of times that the device
continues to send keepalive packets without a response before bringing
the interface down. Enter an integer value greater than 1 and less than
255. If you do not enter a value, the value that was previously set is
used; if no value was specified previously, the default of 5 is used.
If you are using this command with a tunnel interface, the command specifies
the number of times that the device continues to send keepalive packets
without a response before bringing the tunnel interface protocol down.
Sets the encapsulation method used by the interface.
• The encapsulation-type argument specifies the encapsulation type. The
example specifies PPP encapsulation.
Restricts a physical link to join only one designated multilink group interface.
• The group-number argument is the number of the multilink bundle (a
nonzero number).
Enables MLP on the interface.
