Configuring Dynamic Link Aggregation Application Examples
OmniSwitch AOS Release 7 Network Configuration Guide June 2013 page 8-29
Link Aggregation and QoS Example
As shown in the figure on page 8-27, VLAN 12, which uses 802.1Q frame tagging and 802.1p
prioritization, has been configured to use dynamic aggregate group 7. The actual physical links connect
ports 4/1, 4/2, 4/3, and 4/4 on Switch A to ports 1/1, 1/2, 1/3, and 1/4 on Switch C. Follow the steps below
to configure this network:
Note. Only the steps to configure the local ( Switch A) switch are provided here since the steps to config-
ure the remote ( Switch C) switch would not be significantly different.
1 Configure dynamic aggregate group 7 by entering:
-> linkagg lacp agg 7 size 4
2 Configure ports 4/1, 4/2, 4/3, and 4/4 the same actor administrative key (7) by entering:
-> lacp agg 4/1-4 actor admin-key 7
3 Create VLAN 12 by entering:
-> vlan 12
4 Configure 802.1Q tagging with a tagging ID ( VLAN ID) of 12 on dynamic aggregate group 7 by
entering:
-> vlan 12 members 7
5 If the QoS Manager has been disabled (it is enabled by default) enable it by entering:
-> qos enable
Note. Optional. Use the show qos config command to determine if the QoS Manager is enabled or
disabled.
6 Configure a policy condition for VLAN 12 called “vlan12_condition” by entering:
-> policy condition vlan12_condition destination vlan 12
7 Configure an 802.1p policy action with the highest priority possible ( 7) for VLAN 12 called
“vlan12_action” by entering:
-> policy action vlan12_action 802.1P 7
8 Configure a QoS rule called “vlan12_rule” by using the policy condition and policy rules you
configured in steps 8 and 9 above by entering:
-> policy rule vlan12_rule enable condition vlan12_condition action
vlan12_action
9 Enable your 802.1p QoS settings by entering qos apply as shown below:
-> qos apply
10 Repeat steps 1 through 9 on Switch C. Use the same commands as mentioned in the previous steps.
Substitute the port numbers of the commands with the appropriate port numbers of Switch C.
