Dynamic link aggregation

FIGURE 85 Multi-slot aggregate link
By default, the device ports are divided into 4-port groups. The software dynamically assigns a
unique key to each 4-port group. If you need to divide a 4-port group into two 2-port groups, change
the key in one of the groups so that the two 2-port groups have different keys. For example, if you
plan to use ports 1/1 and 1/2 in VLAN 1, and ports 1/3 and 1/4 in VLAN 2, change the key for
ports 1/3 and 1/4.
Viewing keys for tagged ports
To display link aggregation information, including the key for a specific port, enter a command such
as the following at any level of the CLI.
The command in this example shows the key and other link aggregation information for port 1/1.
To display link aggregation information, including the key for all ports on which link aggregation is
enabled, enter the following command at any level of the CLI.
System ID: aaaa.bbbb.cccc
Ports 1/1 - 1/4: Key 0
Ports 3/5 - 3/8: Key 0
All ports in a multi-slot
aggregate link have
the same key.
