Cabletron Systems SmartSwitch manual Applying a Service Profile to an Active PPP Port

Chapter 22: WAN Configuration Guide

Note: If it is necessary to specify a value for Bridging, IP, and/or IPX, you must specify all three of these values at the same time. You cannot specify just one or two of them in the command line without the other(s).

Applying a Service Profile to an Active PPP Port

Once you have created one or more PPP service profiles, you can specify their use on one or more active PPP ports on the SSR. The following command line displays a simplified example of this process:

Apply a service profile to an active WAN port.

ppp apply service <service name> ports <port list>

Configuring Multilink PPP Bundles

The Multilink PPP (MLP) standard defines a method for grouping multiple physical PPP links into a logical pipe, called an “MLP bundle”. Large packets are fragmented and transmitted over each physical link in an MLP bundle. At the destination, MLP reassembles the packets and places them in their correct sequence.

The following table describes the commands for configuring MLP:

Add PPP port(s) to an MLP bundle.	ppp add-to-mlp <mlp > port <port list>
Create MLP bundle(s).	ppp create-mlp <mlp > slot <mlp >
Set MLP encapsulation format.	ppp set mlp-encaps-format ports <mlp >
	[format short-format]
Set the size of frames that	ppp set mlp-frag-size ports <port list>
fragmented for transmission on an	size <size >
MLP bundle.
Set the depth of the queue used to	ppp set mlp-orderq-depth ports <port list>
hold MLP packets for preserving	qdepth <number-of-packets>
the packet order.
Set the depth of the queue used to	ppp set mlp-fragq-depth ports <port list>
hold packet fragments for	qdepth <number-of-packets>
reassembly.

Compression on MLP Bundles or Links

Compression can be applied on either a bundle or link basis if MLP is enabled on PPP links. If compression is enabled on a bundle, the packets will be compressed before
