Assigning an interface to an HDLC link bundle

Configuration restrictions and guidelines

When you assign an interface to an HDLC link bundle, follow these restrictions and guidelines:
POS interfaces and serial interfaces support HDLC link bundling, and can be assigned to one HDLC
•
link bundle.
• An interface can belong to only one HDLC link bundle at any point in time. To assign a member
interface to another HDLC link bundle, remove the interface from the current HDLC link bundle first.
The link layer protocol of an interface to be assigned to an HDLC link bundle must be HDLC. After
•
the interface is assigned to the HDLC link bundle, its link layer protocol cannot be changed.
You can assign interfaces to a nonexistent HDLC link bundle as members.
•
You can assign interfaces on different cards to the same HDLC link bundle.
•
Changing the bundling priority of a member interface might cause the device to determine the state
•
of each member interface.
• The peer interface directly connected to a local HDLC link bundle member interface must also join
the same HDLC link bundle. A HDLC link bundle ID is locally significant. The ID on the peer device
can be different from the local one.
HP recommends that you use the bundle member-priority command and the bundle max-active
•
links command together to make sure that:
Interconnected interfaces at both ends can be Selected.
They can exchange traffic correctly.

Configuration procedure

Step
1. Enter system view.
2. Enter POS interface view or
serial interface view.
3. Enable HDLC encapsulation
on the interface.

Remarks
By default, an HDLC link bundle
interface is up.
When an HDLC link bundle
interface is brought up, the state of
each member interface is
re-determined.
When an HDLC link bundle
interface is shut down, the state of
each Selected interface is placed
into the Negotiated state.
Remarks

By default, PPP encapsulation is
enabled on an interface.
