Disabling Lan Traffic On An Fcoe Link; Configuring The Fc-Map - Cisco AP775A - Nexus Converged Network Switch 5010 Configuration Manual

Configuring FCoE

Disabling LAN Traffic on an FCoE Link

You can disable LAN traffic on an FCoE link.
DCBX allows the switch to send a LAN Logical Link Status (LLS) message to a directly-connected CNA.
Enter the shutdown lan command to send an LLS-Down message to the CNA. This command causes all
VLANs on the interface that are not enabled for FCoE to be brought down. If a VLAN on the interface is
enabled for FCoE, it continues to carry SAN traffic without any interruption.

Configuring the FC-Map

You can prevent data corruption due to cross-fabric talk by configuring an FC-Map which identifies the Fibre
Channel fabric for this Cisco Nexus 5000 Series switch. When the FC-Map is configured, the switch discards
the MAC addresses that are not part of the current fabric.

Step 3
This example shows how to configure the global FC-Map:
switch# configure terminal
switch(config)# fcoe fcmap 0e.fc.2a
OL-16597-01
Command or Action
switch# configure terminal
switch(config)# interface ethernet
slot/port
switch(config-if)# shutdown lan
switch(config-if)# no shutdown lan
Command or Action
switch# configure terminal
switch(config)# fcoe fcmap fabric-map
switch(config)# no fcoe fcmap

Disabling LAN Traffic on an FCoE Link
Purpose
Enters configuration mode.
Specifies an interface to configure, and enters interface
configuration mode.
Shuts down Ethernet traffic on the interface. If the
interface is part of an FCoE VLAN, the shutdown has
no impact on the FCoE traffic.
(Optional)
Reenables Ethernet traffic on the interface.
Purpose
Enters configuration mode.
Configures the global FC-Map. The default value
is 0E.FC.00. The range is from 0E.FC.00 to
0E.FC.FF.
(Optional)
Resets the global FC-Map to the default value of
0E.FC.00.
