Enabling/disabling an HDLC link
bundle interface does not enable or
disable any member interface in
the HDLC link bundle but can affect
the selected states of the member
interfaces.
Assigning an interface to an HDLC link bundle
When you assign an interface to an HDLC link bundle, follow these guidelines:
• You cannot assign interfaces configured with the following features to an HDLC link bundle: IPv4
addresses, IPv4 unnumbered, IPv6 addresses, URPF, NetStream, and IPv6 NetStream. After an
interface is assigned to an HDLC link bundle, you cannot configure any of these features on the
interface either.
• An interface can belong to only one HDLC link bundle at any point in time. To assign an HDLC link
bundle 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 can only be HDLC.
After the interface is assigned to the HDLC link bundle, you are not allowed to change its link layer
protocol.
• 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 finished, the device will determine the state of each member interface in the HDLC link bundle
again.
• The peer interface directly connected to an HDLC link bundle member interface must also join the
HDLC link bundle.
• The bundle member-priority command and the bundle max-active links command usually need to
be used in conjunction, so that interconnected interfaces on two different devices can be both
selected at the same time and exchange traffic successfully.
