Hierarchical QoS (HQoS) for 8x10G modules

HQoS queue policy
HQoS hierarchy is achieved by creating a set of queues.
• A queue is rate shaped and the resulting traffic is referenced as a scheduler flow.
• The scheduler flow out of a queue is referenced by a scheduler policy.
• A queue stores packets based on a selected matching criteria.
FIGURE 18 H-QoS Queue Policy
Figure 16 on page 182 defines queue policies named "Q-7-6", "Q-5-4", "Q-3-2", and "Q-1-0". A
queue policy defines a queue for traffic of a given set of priority levels. Traffic out of a queue is
shaped to a desired rate.
To configure the queue policies, enter commands such as the following.
Brocade(config)# hqos queue-policy Q-7-6
Brocade(config)# shaper-rate 2000
Brocade(config)# shaper-burst-size 10
Brocade(config)# hqos queue-policy Q-5-4
Brocade(config)# shaper-rate 10000000; default shaper rate (10G)
Brocade(config)# shaper-burst-size 10; default burst size (10KB)
Brocade(config)# hqos queue-policy Q-3-2
Brocade(config)# shaper-rate 10000000
Brocade(config)# shaper-burst-size 10
Brocade(config)# hqos queue-policy Q-1-0
Brocade(config)# shaper-rate 10000000
Brocade(config)# shaper-burst-size 10
Syntax: [no] hqos queue-policy queue-name
Syntax: [no] [shaper-rate shaper-rate]
Syntax: [no] [shaper-burst-size shaper-burst-size]
The queue-name is a string up to 128 characters.
