Setting Port Priority Levels
As not all Powered Devices (PDs) connected to the switch have the same priority within a network
setting, the OmniSwitch allows the administrator to specify priority levels on a port-by-port basis.
Priority levels include low, high, and critical.
The default priority level for a port is low.
• Low. This default value is used for port(s) that have low-priority devices attached. In the event of a
power management issue, inline power to low-priority is interrupted first (i.e., before critical and
high priority).
• High. This value is used for port(s) that have important, but not mission-critical, devices attached.
If other ports in the chassis have been configured as critical, inline power to high-priority is given
second priority.
• Critical. This value is used for port(s) that have mission-critical devices attached, and therefore
require top (i.e., critical) priority. In the event of a power management issue, inline power to
critical is maintained as long as possible.
To change the priority level for a particular port, use the lanpower priority command. Since the switch
allows you to set priority levels on a port-by-port basis, be sure to specify chassis/slot/port information
in the command line. For example, the syntax
-> lanpower port 1/1/6 priority critical
changes the priority value of port 6 to the highest priority level of critical. Now that the default value
has been reconfigured, this port should be reserved for those PDs that are mission critical for network
operations.
Setting the Capacitor Detection Method
By default, the capacitor detection method is disabled. To enable it, use the lanpower capacitor-
detection command. For example:
-> lanpower slot 3/1 capacitor-detection enable
Note. The capacitive detection method should only be enabled to support
legacy IP phones. This feature is not compatible with IEEE specifications.
Please contact your Alcatel-Lucent sales engineer or Customer Support
representative to find out which Alcatel-Lucent IP phones models need
capacitive detection enabled.
