Setting Port Priority Levels - Alcatel-Lucent OmniSwitch 6850 Series Hardware User's Manual

Installing and Managing Power over Ethernet (PoE)
To increase or decrease the total power allocated to a slot, use the
you are setting the power allowance for an individual slot, you must specify a slot number in the command
line. For example, the syntax
-> lanpower 3 maxpower 80
reduces the power allowance of the OmniSwitch 6850 Series slot 3 to 80 watts. This value is now the
maximum amount of power the slot can use to power all attached devices (until the value is modified by
the user).

Setting Port Priority Levels

As not all Powered Devices (PDs) connected to the switch have the same priority within a customer
network setting, the OmniSwitch 6850 Series switches allow the user 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 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 main-
tained as long as possible.
To change the priority level for a particular port, use the
allows you to set priority levels on a port-by-port basis, be sure to specify slot/port information in the
command line. For example, the syntax
-> lanpower 8/22 priority critical
changes the priority value of port 22 of the OmniSwitch 6850 Series slot 8 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.
