VLAN statistics for a port (CNA and NIC)
Use the BCU ethport command to display VLAN statistics for a specific port, such as transmit and
receive bytes, duration, and status.
ethport --vlanquery <pcifn> <vlan_id>
where:
pcifn
Specifies the PCIFN function number related to the port.
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 (stand-up adapters)
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>
where:
port_id
ID of the port for which you want to enable beaconing. This could be the
PWWN, port hardware path, or user-specified port name. This could also be
the adapter-index/port-index. For example, to specify adapter 1, port 1, you
would use 1/1 as the port identification.
