This example shows how to configure the advertisement interval for the fabric on a Cisco MDS 9500 switch:
switch#
configure terminal
switch(config)#
fcoe fka-adv-period 42
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.

DETAILED STEPS
Purpose
Command or Action
Enters configuration mode.
configure terminal
Example:

switch(config)#
Step 1
Specifies an interface to configure, and enters interface
configuration mode. Use

interface ethernet slot
/
port
Example:
switch(config)# interface e 2/1
switch(config-if)#
Step 2
Shuts down Ethernet traffic on the interface. If the interface is
part of an FCoE VLAN, the shutdown has no impact on the
shutdown lan
Example:
switch(config-if)# shutdown lan
Step 3
FCoE traffic. Use
no shutdown lan
to reenable Ethernet traffic
on this interface.
(Optional)
Displays information about the interface.
show interface
Example:
switch(config-if)# show interface
