Link Aggregation and QoS Example
As shown in the figure on
page 11-32
, 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.
1
Configure dynamic aggregate group 7 by entering:
-> lacp linkagg 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 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
3
Create VLAN 12 by entering:
-> vlan 12
4
Configure 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
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 (i.e., 7) for VLAN 12 called
“vlan12_action” by entering:
-> policy action vlan12_action 802.1P 7
8
Configure 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
9
Enable your 802.1p QoS settings by entering
qos apply
as shown below:
-> qos apply
