Qos On E_Ports; Figure 61 Qos Traffic Prioritization - Brocade Communications Systems 53-1001763-02 Administrator's Manual

For example,
traffic prioritization is as follows:

For this fabric, you could set up the following QoS zones:

QOSL_Zone3

QoS on E_Ports

In addition to configuring the hosts and targets in a zone, you must also enable QoS on individual
E_Ports that might carry traffic between the host and target pairs. Path selection between the
"host,target" pairs is governed by FSPF rules and is not affected by QoS priorities. For example, in
Figure
NOTE
By default, QoS is enabled on 8 Gbps ports, except for long-distance 8 Gbps ports. QoS is disabled
by default on all 4 Gbps ports and long-distance 8 Gbps ports.

Figure 61 shows a fabric with two hosts (H1, H2) and three targets (S1, S2, S3). The
Traffic between H1 and S1 is high priority.
Traffic between H1 and S3 and between H2 and S3 is low priority.
All other traffic is medium priority, which is the default.
