Configuring Short Sequence Number Header Format Negotiation - HP MSR Router Series Wan Access Configuration Manual

Step
6. (Optional.) Start the timer for
waiting for the expected
fragment.
7. (Optional.) Disable MP
fragmentation.
8. (Optional.) Set the interface
description.
9. Set the keepalive interval.
10. Set the keepalive retry limit.
11. Set the MTU size of the
interface.
12. Set the expected bandwidth
of the interface.
13. (Optional.) Restore the default
settings for the interface.
14. Bring up the interface.
15. Return to system view.
16. Enter interface view.
17. Assign the interface to a
specified MP-group interface,
and enable MP for the
interface.

Configuring short sequence number header format negotiation

By default, an MP bundle receives and transmits fragments with long sequence numbers.
• To receive fragments with short sequence numbers, the local end should request the peer to transmit
short sequence numbers during LCP negotiation. After the negotiation succeeds, the peer transmits
fragments with short sequence numbers.
To transmit fragments with short sequence numbers, the local end should ask the peer to send a
•
request for receiving short sequence numbers during LCP negotiation. After the negotiation
succeeds, the local end transmits fragments with short sequence numbers.
The sequence number format (long or short) of an MP bundle depends on the configuration of the first
channel joining the MP bundle.

Remarks
By default, the timer is not started.
By default, MP fragmentation is
enabled.
After you configure this command
on an interface, the settings
configured with the ppp mp lfi
enable and ppp mp min-fragment
commands do not take effect on
the interface.
Optional.
The default setting is interface
name Interface, for example,
MP-group3 Interface.
The default setting is 10 seconds.
The default setting is 5.
The default setting is 1500 bytes.
By default, the expected
bandwidth (in kbps) is the interface
baud rate divided by 1000.
N/A
By default, an interface is up.

N/A
By default, an interface is enabled
with PPP.
