Setting Port Priority Levels - Alcatel-Lucent OmniSwitch 6600 Family Hardware User's Manual

Installing and Managing Power over Ethernet (PoE)
To increase or decrease the total power allocated to a slot, use the
Because 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 OmniSwitch 6600-P24 slot 3 to 80 watts. This value is now the maxi-
mum amount of power the slot can use to power all attached devices (until the value is modified by the
user).

Setting Port Priority Levels

Because not all Powered Devices (PDs) connected to the switch have the same priority within a customer
network setting, OmniSwitch 6600-P24 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 ports is interrupted first (i.e., before critical and
high-priority ports).
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 ports 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 ports is
maintained 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 OmniSwitch 6600-P24 slot 8 to the highest priority level of criti-
cal. Now that the default value has been reconfigured, this port should be reserved for those PDs that are
mission critical for network operations.
