Usage guidelines
This command applies to the incoming direction only. To enable the local end to transmit packets with
short sequence numbers, configure this command on the remote end.
The sequence number format (long or short) of an MP bundle depends on the configuration of the first
channel joining the MP bundle.
To negotiate the use of short sequence numbers on a dialer MP bundle, configure the command on the
dialer interfaces and the ISDN D channels. To negotiate the use of short sequence numbers on a
common MP bundle, use the command on all its channels. The command will cause PPP re-negotiation.
Examples
# Configure the short sequence number header format of MP in the incoming direction of interface Serial
2/1/0.

Use undo ppp mp sort-buffer-size to restore the default.
Syntax
ppp mp sort-buffer-size size
undo ppp mp sort-buffer-size
Default
The MP sort buffer size factor is 1.
