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). • You must be running Fabric OS v6.3.0 or later to create QoS zones using D,I notation. • QoS zones using D,I notation are not supported for QoS over FCR. • QoS zones using D,I notation should not be used for loop or NPIV ports.
