Command Remarks
12. (Optional.) Bring up the HDLC
link bundle interface
undo shutdown
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.
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:
• 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.
• If you change the bundling priority of a member interface after the HDLC link bundle configuration
is complete, the device will determine the state of each member interface in the HDLC link bundle
again.
• The peer interface directly connected to a local HDLC link bundle member interface must also join
the same HDLC link bundle. The ID of the HDLC link bundle on the peer device can be different from
the local one. A HDLC link bundle ID is of only local significance.
• HP recommends that you use the bundle member-priority command and the bundle max-active
links command together to make sure:
{ Interconnected interfaces at both ends can be Selected at the same time.
{ They can exchange traffic correctly.
