Beaconing

The Ethernet Test options are described in Table 17 .
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.
Configuring beaconing using the GUI
You can configure beaconing from an HBA port, an FCoE port, or an Ethernet port.
1. Select an HBA port, an FCoE port, or an Ethernet port from the device tree.
2. Select Configure > Beacon from the Host Connectivity Manager.
3. Click either the Beacon Port check box or the Beacon 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.
Refer to “diag” on page 165 for details about this command.
Enter the following command to blink the appropriate link for physical identification.
bcu fcdiag - -linkbeacon <port_id> {on|off}
Refer to “fcdiag” on page 175 for details about this command.
