R3303-HP HSR6800 Routers Interface Command Reference

226
• ETSI uses the AU-4 multiplexing scheme, where the lower-order payload is aggregated into the
VC-4 higher-order path. VC-4 plus an AU pointer forms an AU-4. This AU-4 can be synchronized
and multiplexed to form one AUG.
When the CPOS interface is operating in SDH mode, you can choose to multiplex AUG to AU-4 or AU-3
by using the multiplex mode command. When the CPOS interface is operating in SONET mode, AUG
can be multiplexed only to AU-3 and the multiplex mode command is invalid.
Examples
# In SDH mode, multiplex AUG to AU-3.

ppp mp soft-binding
Use the ppp mp soft-binding command to configure the serial interface to use the software bundling
mode.
Use the undo ppp mp soft-binding command to restore the default.

Usage guidelines
In software bundling mode, because packets are all fragmented and reassembled by the CPU, the serial
interface cannot be bundled with a large number of links.
In hardware bundling mode, because packets are fragmented and reassembled through hardware,
which frees the CPU from these tasks, the serial interface can be bundled with a large number of links.
The HIM-CL1P and HIM-CL2P interface modules do not support cross-port hardware MP bundling. On
these interface modules, you can use software bundling to meet cross-port MP requirements.
Examples
# Set the bundling mode of Serial 1/0/0/1:1 formed by bundles on CPOS 1/0/0 to software bundling.
