4.4.2 Frame Distribution Methods in Link Aggregation

How frames are distributed to physical ports that make up an aggregation group is determined by contents of a frame (source
and destination MAC addresses).
There are three ways to specify how frames are distributed:
Frame distribution based on destination MAC address (dst-mac)
The destination port is determined based on the destination MAC address of the frames.
Frame distribution based on source MAC address (src-mac)
The destination port is determined based on the source MAC address of the frames.
Frame distribution based on destination and source MAC addresses (dst-src-mac)
The destination port is determined based on the destination and source MAC addresses of the frames.
To set a distribution method, carry out the following procedure in the administrator EXEC mode.
xg# configure terminal
xg(config)# link-aggregation agg-port <1-6>
protocol {none | lacp}
load-balance dst-mac|src-mac|dst-src-mac}
port <1-12> <1-12>
xg(config)# exit

4.4.3 The Number of Ports That Require Linkup

It is possible to specify the number of ports in a linkup state as conditions for enabling linkup for an aggregation group. If the
number of ports that make up an aggregation group in a linkup state is less than the specified number of ports, the aggregation
group changes to a linkdown state.
For static link aggregation
If the number of ports that make up an aggregation group in a linkup state no longer satisfies the specified number of
ports, the aggregation group changes to a linkdown state.
For LACP link aggregation
If the number of ports that make up an aggregation group for LACP has been established no longer satisfied the
specified number of ports, the aggregation group changes to a linkdown state.
To set the number of ports in the aggregation group, carry out the following procedure in the administrator EXEC mode.
xg# configure terminal
xg(config)# link-aggregation agg-port <1-6>
protocol {none | lacp} minimum-port <1-12>
port <1-12> <1-12>
xg(config)# exit
If there are not many MAC addresses to be distributed on an aggregation group, the distribution
among the destination ports tends to become biased. To reduce such bias, use a distribution method
that uses more MAC addresses.
For example, if a server is connected to an aggregation group and a client is connected to a different
port, it is recommended that you use either "src-mac" or "dst-src-mac".
