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 trac 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 specied fabric. You
must congure a separate FCoE VLAN for each fabric to which FCoE trac is forwarded. Any non-FCoE trac
sent on a dedicated FCoE VLAN will be dropped.
You congure the association between a dedicated VLAN, which carries FCoE trac 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 congured as a tagged
member of the FCoE VLAN.
For more information about VLANs and the commands to congure them, refer to the Virtual LAN (VLAN)
Commands section.
Example (Single
Range)
Dell(conf)#interface vlan 10
Dell(conf-if-vl-3)#
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 conguration on the port so that the priorities are included in DCBX negotiation with peer PFC devices.
Syntax
pfc mode on
To disable the PFC conguration, use the no pfc mode on command.
Defaults PFC mode is on.
Command Modes DCB MAP
Supported Modes Programmable-Mux (PMUX)

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 trac. To achieve
complete lossless handling of trac, also enable PFC on all DCB egress ports or congure the dot1p priority-queue
assignment of PFC priorities to lossless queues (refer to pfc no-drop queues).
