Monitoring PPP WAN Ports
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
processing by MLP. If compression is enabled on a link, the packets will be compressed
after the MLP processing.
In general, choose bundle compression over link compression whenever possible.
Compressing packets before they are “split” by MLP is much more efficient for both the
compression algorithm and the WAN card. Link compression is supported to provide the
widest range of compatibility with other vendors’ equipment.
Monitoring PPP WAN Ports
Once you have configured your PPP WAN interface(s), you can use the CLI to monitor
status and statistics for your WAN ports. The following table describes the monitoring
commands for WAN interfaces, designed to be used in Enable mode:
Set the size of frames that
fragmented for transmission on an
MLP bundle.
ppp set mlp-frag-size ports <port list> size <size >
Set the depth of the queue used to
hold MLP packets for preserving
the packet order.
ppp set mlp-orderq-depth ports <port list> qdepth
<number-of-packets>
Set the depth of the queue used to
hold packet fragments for
reassembly.
ppp set mlp-fragq-depth ports <port list> qdepth
<number-of-packets>
Display a particular PPP service
profile.
ppp show service <service name>
Display all available PPP service
profiles.
ppp show service all
Display bridge NCP statistics for
specified PPP WAN port.
ppp show stats port <port name> bridge-ncp
Display IP NCP statistics for
specified PPP WAN port.
ppp show stats port <port name> ip-ncp
Display link-status statistics for a
specified PPP WAN port.
ppp show stats port <port name> link-status
Displays information for PPP ports
that are added to MLP bundles.
ppp show mlp <mlp list>|all-ports
