Configuring An Hdlc Link Bundle Interface - H3C SR6600 Configuration Manual

same bundling priority are sorted in the ascending order of index numbers. The first N
member interfaces enter the selected state, while the remaining (M-N) member
interfaces enter the ready state.
The SR6600 routers allow member interfaces with different transmission rates to be
selected at the same time.
The maximum number of member interfaces that can be selected in a bundle is set by
the bundle max-active links command. If this upper limit is not set, the maximum
number of selected member interfaces that the router supports for a bundle applies.
The SR6600 routers support up to eight selected member interfaces in a bundle.
4) Suppose the number of member interfaces meet the above conditions for being
selected is P. If the number of selected member interfaces required to bring up the
HDLC link bundle is set to Q and P is smaller than Q, none of the P member interfaces
will be selected. Instead, they all stay in the ready state. The same situation occurs
when the sum of bandwidths of the P member interfaces is smaller than the minimum
amount of bandwidth required to bring up the HDLC link bundle.
If an HDLC link bundle does not contain any selected member interfaces, the HDLC link
bundle interface is brought down, and cannot forward traffic. It will not be brought up and
forward traffic until selected member interfaces are detected in the HDLC link bundle. The
bandwidth of an HDLC link bundle is the total bandwidth of all selected member interfaces.
Load balancing modes
An HDLC link bundle forwards traffic through its selected member interfaces. When
multiple selected member interfaces exist in an HDLC link bundle, the router chooses some
of the selected member interfaces to forward traffic according to its load balancing mode.
Two load balancing modes are available:
Per-flow load balancing, where packets of the same flow are forwarded on the same
selected member interface. A flow is identified by an IP quintuple of source IP address,
destination IP address, protocol ID, source port, and destination port.
Per-packet load balancing, where packets are distributed evenly across all selected
member interfaces in a round-robin way.
