Hierarchical QoS (HQoS) for 8x10G modules

HQoS towards the customers
HQoS can shape the traffic towards the downstream 1GE links using the “Logical” port level of
HQoS on Brocade devices.
In Figure 9 on page 174, two logical ports would be defined and shaped to 1Gb/s.
The HQoS policy is configured with Customer traffic connected to the appropriate “Logical” port on
the HQoS hierarchy.
