Configuring Short Sequence Number Header Format Negotiation; Configuring The Mp Endpoint Descriptor - HPE FlexNetwork MSR series Configuration Manual

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.
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. Note that the command will cause PPP
re-negotiation.
To configure short sequence number header format negotiation for MP:
Step
1. Enter system view
2. Enter interface view.
3. Trigger MP short sequence number
header negotiation, specifying that
the interface receive fragments with
short sequence numbers after the
negotiation succeeds.

Configuring the MP endpoint descriptor

When MP is configured by using a VT interface, an MP endpoint makes link binding decisions based
on the remote endpoint descriptors. It assigns the links that receive the same endpoint descriptor to
the same bundle. To avoid incorrect link binding on a VT interface, make sure the link descriptors
used by different devices are unique. You must re-configure an endpoint descriptor for a device if the
default endpoint descriptor (device name) cannot uniquely identify the MP bundle at the remote end.
When MP is configured by using an MP-group interface, the negotiating endpoints do not base their
binding decisions on the endpoint descriptor. By default, the endpoint descriptor of an interface in an
MP-group is the MP-group interface name. When you configure an endpoint descriptor for the
interface, the configured MP endpoint descriptor takes effect.
If the endpoint descriptor exceeds 20 bytes, the first 20 bytes are taken as the endpoint descriptor.
To configure the MP endpoint descriptor of an interface for LCP negotiation:
Step
1. Enter system view.
2. Enter interface view.
3. Configure the MP endpoint
descriptor.
