Hierarchy Level


Configure the IEEE 802.1p code point value to which all traffic received from the Fibre Channel (FC) network on the specified FC interface is rewritten. After the code point value is rewritten, the interface forwards the traffic to the Ethernet (FCoE) network. This works in conjunction with configuring a fixed classifier on the FC interface. The fixed classifier maps all traffic from the FC network into one lossless forwarding class (the lossless forwarding class must be mapped to the code point specified in the rewrite value). Traffic mapped to the lossless forwarding class uses the IEEE 802.1p priority specified by the code point bits in the rewrite value.

FCoE networks typically use priority 3 (IEEE code point 011) for FCoE traffic. The QFX Series default configuration uses IEEE 802.1p priority 3 for FCoE traffic. Rewriting the code point value enables you to change the IEEE 802.1p priority of the FCoE traffic if the Ethernet network uses a different priority than priority 3 (code point 011).

The system supports only one IEEE 802.1p code point value per FC interface. You cannot configure more than one IEEE 802.1p rewrite value per FC interface. In addition, you can specify only one rewrite value per local FCoE-FC gateway fabric; all interfaces in the local fabric must use the same rewrite value. Attempting to configure FC interfaces in the same local fabric with different rewrite values generates a commit error. You can specify different rewrite values for interfaces that belong to different local FCoE-FC gateway fabrics.
