Disabling Lan Traffic On An Fcoe Link - Cisco Nexus 7000 series Configuration Manual

Disabling LAN Traffic on an FCoE Link

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.
SUMMARY STEPS
1. configure terminal
2. interface ethernet slot/port

Purpose
Enters configuration mode.
Specifies an interface to configure, and enters interface
configuration mode. Use ? to view a list of supported interfaces.
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. Use no shutdown lan to reenable Ethernet traffic
on this interface.
(Optional)
Displays information about the interface.
