Beaconing 5
Beaconing
Beaconing is a continuous signaling of error conditions on a LAN. Beaconing can occur either on
the port or on one or both sides of the link (known as end-to-end beaconing). Link end-to-end
beaconing provides a mechanism to start beaconing on both the adapter side and the switch side.
NOTE
Port beaconing is not supported on the Brocade 804 mezzanine card.

Configuring beaconing using HCM

You can configure beaconing from an HBA port.
1. Select an HBA port from the device tree.
2. Select Configure > Beacon from the Host Connectivity Manager.
3. Click either the Port check box or the Link check box to enable the feature.

Configuring beaconing using the BCU

Enter the following command to blink the appropriate port LED for physical identification.
bcu diag --beacon <port_id> {on | off} [-t <secs>]
where:
duration Blinks the local port for the specified number of seconds. The default is 0,
which means infinite blinking.
