Version Description
9.4(0.0) Introduced on the FN I/O Aggregator.
9.3(0.0) Introduced on the M I/O Aggregator.
Usage Information
FCoE storage traffic received from servers on an M I/O Aggregator with the PMUX module NPIV proxy gateway
is de-capsulated into Fibre Channel packets and forwarded over FC links to SAN switches in a specified fabric. You
must configure a separate FCoE VLAN for each fabric to which FCoE traffic is forwarded. Any non-FCoE traffic
sent on a dedicated FCoE VLAN will be dropped.
You configure the association between a dedicated VLAN, which carries FCoE traffic from server CNAs over the
NPIV proxy gateway to a SAN fabric in which destination storage arrays are installed, in an FCoE map by using the
fabric id vlan command.
When you apply an FCoE map to a server-facing Ethernet port, the port is automatically configured as a tagged
member of the FCoE VLAN.
For more information about VLANs and the commands to configure them, refer to the Virtual LAN (VLAN)
Commands section.
Example (Single

Related Commands
fcoe-map — creates an FCoE map which contains the parameters used in the communication between servers
and a SAN fabric.
pfc mode on
Enable the PFC configuration on the port so that the priorities are included in DCBX negotiation with peer PFC devices.
Syntax
pfc mode on
To disable the PFC configuration, use the no pfc mode on command.

Version Description
9.9(0.0) Introduced on the FN IOM.
9.4(0.0) Introduced on the FN I/O Aggregator.
9.2(0.0) Introduced on the M I/O Aggregator.
Usage Information
By applying a DCB input policy with PFC enabled, you enable PFC operation on ingress port traffic. To achieve
complete lossless handling of traffic, also enable PFC on all DCB egress ports or configure the dot1p priority-queue
assignment of PFC priorities to lossless queues (refer to pfc no-drop queues).
