Diagnostics

Displaying virtual port statistics through BCU

Use the vlan --query command to display VLAN statistics.

vlan --query <port_id> <vlan_id>

where:

port_id Specifies the Ethernet port associated with the VLAN.

vlan_id Specifies the VLAN identifier. The range for the VLAN ID is 1 to 4094.

Diagnostics

Diagnostics, available through BCU commands and HCM, evaluate the integrity of adapter

hardware and end-to-end connectivity in the fabric. All of these diagnostics can be used while the

system is running.

NOTE

Be sure to disable the port before running any type of port diagnostics.

NOTE

It is advisable to not perform other operations on the adapter while running HCM or BCU diagnostics.

Beaconing

Initiate beaconing on a specific adapter port to flash the port LEDs and make it easier to locate the

adapter in an equipment room.

Initiate link beaconing to flash the LEDs on a specific adapter port and the LEDs on a connected

switch port to verify the connection between adapter and switch. When you initiate link beaconing,

commands are sent to the other side of the link. When the remote port receives these commands,

that port’s LEDs flash. The remote port sends a command back to the originating port. When that

port receives this command, the port’s LEDs flash.

NOTE

To initiate link beaconing, this feature must be available on the connected switch.

Toggle beaconing on and off and set beaconing duration using the BCU or HCM.

Enabling beaconing through BCU

Use the diag --beacon command to enable beaconing for a specific adapter port.

diag --beacon <port_id> <on | off> [<duration>]

where:

port_id ID of the port for which you want to enable beaconing.

duration Length of time between blinks.

Use the fcdiag --linkbeacon command to enable link beaconing.
