Limitations and restrictions for traffic prioritization
Note the following configuration rules for traffic prioritization:
• If a host and target are included in two or more QoS zones with different priorities, the zone
with the lowest priority takes precedence. For example, if an effective zone configuration has
QOSH_z1 (H,T) and QOSL_z2 (H,T), the traffic flow between H and T will be of low QoS priority.
Additionally, if QOSH_z1 (H,T) overlaps with a “domain,port” zone at the H port, the traffic flow
between H and T is dropped to medium priority and the H port is marked as a session-based
zoning port.
• Traffic prioritization is enforced on the egress ports only, not on the ingress ports.
• Traffic prioritization is not supported on 10 Gbps ISLs.
• Traffic prioritization is not supported on mirrored ports.
• Traffic prioritization is not supported over LSAN zones. The traffic is always medium priority in
the ingress edge fabric, the backbone fabric, and the egress edge fabric.
• Traffic prioritization is not supported on a CryptoTarget container (redirection zone). See the
Fabric OS Encryption Administrator’s Guide for information about redirection zones.
• Traffic prioritization is not supported in McDATA Fabric Mode (interopmode 2) or Open Fabric
Mode (interopmode 3).
