Configuring Static Link Aggregation

Application Example

Static link aggregation groups are treated by the switch's software the same way it treats individual physi-
cal ports. This section demonstrates this by providing a sample network configuration that uses static link
aggregation along with other software features. In addition, a tutorial is provided that shows how to
configure this sample network using Command Line Interface (CLI) commands.
The figure below shows VLAN 8, which has been configured on static aggregate 1 and uses 802.1Q
tagging. The actual physical links connect ports 4/1, 4/2, 4/3, and 4/4 on Switch A to port 2/41, 2/42, 2/43,
and 2/44 on Switch B.
Follow the steps below to configure this network:
Note. Only the steps to configure the local (i.e., Switch A) switch are provided here since the steps to
configure the remote (i.e., Switch B) switch would not be significantly different.
1
Configure static aggregate group 1 by entering static linkagg 1 size 4 as shown below:
-> static linkagg 1 size 4
2
Assign ports 4/1, 4/2, 4/3, and 4/4 to static aggregate group 1 by entering:
-> static agg 4/1 agg num 1
-> static agg 4/2 agg num 1
-> static agg 4/3 agg num 1
-> static agg 4/4 agg num 1
3
Create VLAN 8 by entering:
-> vlan 8
4
Configure 802.1Q tagging with a tagging ID of 8 on static aggregate group 1 (on VLAN 8) by enter-
ing:
-> vlan 8 802.1q 1
5
Repeat steps 1 through 4 on Switch B. All the commands would be the same except you would substi-
tute the appropriate port numbers.
Note. Optional. Use the
