Application Examples Configuring Dynamic Link Aggregation
page 13-36 OmniSwitch 6600 Family Network Configuration Guide April 2006
Link Aggregation and QoS Example
As shown in the figure on page 13-34, VLAN 12, which uses 802.1Q frame tagging and 802.1p prioritiza-
tion, 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 (a stack of four OmniSwitch 6648
switches). Follow the steps below to configure this network:
Note. Only the steps to configure the local (i.e., Switch A) are provided here since the steps to configure
the remote (i.e., Switch C) would not be significantly different.
1Configure dynamic aggregate group 7 by entering:
-> lacp linkagg 7 size 4
2Configure ports 4/1, 4/2, 4/3, and 4/4 the same actor administrative key (7) by entering:
-> lacp agg 4/1 actor admin key 7
-> lacp agg 4/2 actor admin key 7
-> lacp agg 4/3 actor admin key 7
-> lacp agg 4/4 actor admin key 7
3Create VLAN 12 by entering:
-> vlan 12
4Configure 802.1Q tagging with a tagging ID (i.e., VLAN ID) of 12 on dynamic aggregate group 7 by
entering:
-> vlan 12 802.1q 7
5If 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.
6Configure a policy condition for VLAN 12 called “vlan12_condition” by entering:
-> policy condition vlan12_condition destination vlan 12
7Configure an 802.1p policy action with the highest priority possible (i.e., 7) for VLAN 12 called
“vlan12_action” by entering:
-> policy action vlan12_action 802.1P 7
8Configure a QoS rule called “vlan12_rule” 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
9Enable your 802.1p QoS settings by entering qos apply as shown below:
-> qos apply
