Configuring Fragmentation and Reassembly for MLPPP Bundles
If you issue the ppp fragmentation command or the ppp reassembly command in
the context of an MLPPP bundle, the command affects all the current member links
in the bundle. This enables you to issue a single command for the entire bundle
instead of having to issue individual commands for each member link in the bundle.
For example, the following commands configure MLPPP fragmentation and
reassembly for all member links in the bundle group1.
host1(config)# interface mlppp group1
host1(config-if)# ppp fragmentation 128
host1(config-if)# ppp reassembly 1590
host1(config-if)# exit
host1(config)#
Any member links added to the bundle after you issue an MLPPP configuration
command in the bundle context are not affected by the command. For example, if
you add a member link to the group1 bundle after you issue the
ppp fragmentation
or ppp reassembly command, MLPPP fragmentation and reassembly for this link
and any member links subsequently added to the bundle is not enabled.
Configuring Multiclass MLPPP
Multiclass MLPPP enables you to fragment data packets of different priorities into
multiple classes in an MLPPP bundle. It also enables you to send high-priority packets
between fragments of larger, lower priority packets. Multiclass MLPPP ensures that
high-priority, delay-sensitive traffic, such as voice and video, are received in the
proper sequence.
For information about multiclass MLPPP, see “Configuring Multiclass Multilink PPP”
on page 349.
Monitoring MLPPP
Use the commands in this section to display information about MLPPP interfaces.
You can set a statistics baseline for MLPPP serial (member link) or bundle (multilink)
interfaces using the
baseline ppp command. Use the delta keyword with the show
commands described below to display statistics with the baseline values subtracted.
After you configure multilink PPP, you can use the show ppp interface commands
to display configuration and statistics information about MLPPP and MLPPP
fragmentation and reassembly.
