Guidelines for VSAN Interface Configuration

Guidelines for VSAN Interface Configuration
• Create a VSAN before creating the interface for that VSAN. If a VSAN does not exist, the interface
• Create the interface VSAN; it is not created automatically.
• If you delete the VSAN, the attached interface is automatically deleted.
• Configure each interface only in one VSAN.
Tip
After configuring the VSAN interface, you can configure an IP address or Virtual Router Redundancy Protocol
(VRRP) feature. See the

Guidelines and Limitations for Port Beaconing

• The port beacon LED on directly attached peers can only be controlled when the link to the peer is up
• If you enable port beacon mode on a port using the beacon interface command and then enable beacon
• If you send a port beaconing request from Switch A to Switch B using the beacon interface command
• If you enable port beacon mode on a port using the beacon interface command and then perform a
• If you send a port beaconing request with the duration set to 0 from Switch A that is running Cisco MDS
• This feature is not supported on Cisco MDS switches that are operating in the Cisco NPV mode.
• This feature is not supported on port-channel interfaces. It is supported only on individual Fibre Channel

mode using the switchport beacon command, the beacon mode takes precedence and the port beacon
mode will be disabled. If you disable the beacon mode, the port beacon mode will continue to be disabled
until you enable the port beacon mode again.
and then if you enable switchport beacon locally on Switch B, the switchport beacon command takes
precedence over the port beaconing request and stops the LED activity on Switch B. However, if you
run the show interface command on Switch A, the output will continue to show the port beaconing status
for the port on Switch B until the specified duration is reached.
system switchover using the system switchover command, the show interface command on the switch
does not show the port beaconing status as on. However, the port LED to which the port beaconing
request was sent continues to beacon with the specified parameters until the specified duration is reached
or when you run the switchport beacon command to override the port beaconing request for the port.
