Chapter 18 Configuring MLPPP Backhaul
Configuring Additional MLPPP Settings
You can perform a variety of other configurations on an MLPPP bundle, including the following:
• Modifying the maximum fragment size
• Modifying fragmentation settings
• Enabling or disabling fragmentation
• Enabling or disabling interleaving
• Configuring distributed MLPPP (dMLPPP)
• Configuring multiclass MLPPP
For more information about configuring MLPPP, see the Dial Configuration Guide, Cisco IOS Release
15.0S.
MLPPP Offload
By default, the Cisco MWR 2941 offloads processing for distributed MLPPP (dMLPPP) to the network
processor for improved performance. However, the Cisco MWR 2941 does not support some dMLPPP
settings on offloaded bundles. The Cisco MWR 2941 does not support the following options on
offloaded dMLPPP bundles:
• ppp multilink idle-link
• ppp multilink queue depth
• ppp multilink fragment maximum
• ppp multilink slippage
• ppp timeout multilink lost-fragment
Note If you have a bundle that requires the use of these options, contact Cisco support for assistance.
Step 5
Router(config-if)# keepalive
[period [retries]]
Example:
Router(config-if)# keepalive 1 5
Enables keepalive packets on the interface and specifies the number of
times the keepalive packets are sent without a response before the router
disables the interface. The syntax is as follows:
• period—(Optional) Integer value in seconds greater than 0. The
default is 10.
• retries—(Optional) Specifies the number of times that the device will
continue to send keepalive packets without response before bringing
the interface down. Integer value greater than 1 and less than 255. If
omitted, the value that was previously set is used; if no value was
specified previously, the default of 5 is used.
Step 6
exit
Example:
Router(config)# exit
Router#
Exits configuration mode.
