WRED support for HQoS
1
Configuring steps
HQoS over LAG is configured under the primary port of the LAG.
1. Use this command to set up a LAG and Primary port
Brocade # lag “testLag” dynamic id 1
ports ethernet 4/3 to 4/5
primary-port 4/3
deploy
2. Use the following commands to configure HQoS on the primary port of the LAG
Brocade (config)# interface ethernet 4/3
Brocade (config-if-eth-4/3) # hqos service-policy output policy-1
Brocade (config-if-eth-4/3) # hqos-map flow-1-1.flow-2-1.flow-3-1 match vlan 200
(Existing VPLS End-point)
Brocade (config-if-eth-4/3) # hqos-map flow-1-1.flow-2-1.flow-3-0 match vpls 501
peer 1.1.1.2 (VPLS MPLS Uplink)
Brocade (config-if-eth-4/3)# enable
The HQoS configuration will be replicated on both the secondary ports (4/4, 4/5) of the
LAG.Depending on the traffic patterns and the hash function used, lag hashing may result in
non-uniform distribution of traffic to member ports. Each member port is individually capable of
forwarding the traffic which is configured as part of the corresponding HQoS-policy and HQoS-map
rule. The HQoS over LAG is supported both for the VPLS End-point & VPLS MPLS Uplink.
Limitations
• All member ports need to have the same HQoS configuration before the LAG can be deployed.
This condition covers the following cases.
• No HQoS configuration exists on any member ports
• HQoS configuration on all member ports is the same
• If no HQoS configuration exists on any member ports, member ports with different
capabilities (HQoS capable and non-HQoS capable) will be allowed.
WRED support for HQoS
This feature allows you to support WRED for HQoS customer and other queue types.
Feature highlights
This feature is implemented using enhancements to existing CLI commands for QoS on regular port
queue types.
Configuring steps
1. Use the following commands to set up WRED on a 10G module and a customer-queue type.
Brocade # hqos customer-queue-type 0 wred enable module-type 8x10g
Brocade # hqos customer-queue-type 0 wred averaging-weight 1 module-type 8x10g
