Figure 5.8 Multi-slot aggregate link
All ports in a multi-slot
aggregate link have
the same key.
Port 3/5
Port 3/6
Port 3/7
Port 3/8
System ID: aaaa.bbbb.cccc
Ports 1/1 - 1/4: Key 0
Ports 3/5 - 3/8: Key 0
By default, the device's 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.
NOTE: If you change the key for a port group, HP recommends that you use the value 10000 or higher, to avoid
potential conflicts with dynamically created keys.
To change link aggregation parameters, use the following CLI method.
USING THE CLI
You can configure one or more parameters on the same command line, and you can enter the parameters in any
order. For example, to change a port group's key from the one assigned by the software to another value, enter
commands such as the following:
HP9300(config)# interface ethernet 1/1 to 1/4
HP9300(config-mif-1/1-1/4)# link-aggregate configure key 10000
HP9300(config-mif-1/1-1/4)# interface ethernet 3/5 to 3/8
HP9300(config-mif-3/5-3/8)# link-aggregate configure key 10000
This command changes the key for ports 1/1 – 1/4 and 3/5 – 3/8 to 10000. Since all ports in an aggregate link
must have the same key, the command in this example enables ports 1/1 – 1/4 and 3/5 – 3/8 to form a multi-slot
aggregate link.
Syntax: [no] link-aggregate configure [system-priority <num>] | [port-priority <num>] | [key <num>] |
[type server | switch]
The system-priority <num> parameter specifies the HP device's link aggregation priority. A higher value
indicates a lower priority. You can specify a priority from 0 – 65535. The default is 1.
The port-priority <num> parameter specifies an individual port's priority within the port group. A higher value
indicates a lower priority. You can specify a priority from 0 – 65535. The default is 1.
The key <num> parameter identifies the group of ports that are eligible to be aggregated into a trunk group. The
software automatically assigns a key to each group of ports. The software assigns the keys in ascending
numerical order, beginning with 0. You can change a port group's key to a value from 0 – 65535.
NOTE: If you change the key for a port group, HP recommends that you use the value 10000 or higher, to avoid
potential conflicts with dynamically created keys.
The type server | switch parameter specifies whether the port group is connected to a server (server) or to
another networking device (switch). The default is switch.
