Procedure Steps - Avaya 8300 Configuration

PoE configuration example reference using the ACLI
Prerequisites
You must log on to the Global Configuration and Interface Configuration modes in the
ACLI.

Procedure steps

1. Set power limits for ports.
2. Set the device type.
3. Set the priority for port power allocation.
68 Configuration — Power over Ethernet
To improve power management at the PSE, you can limit the amount of power
supplied on each port. In this example, you install two Ethernet Routing Switch
8301AC power supplies at 110 V in the Avaya Ethernet Routing Switch 8300. This
provides enough power for two 8348TX-PWR or 8348GTX-PWR modules with 200
watts for each module.
To manage the total power requirement, this example limits the power for all the
webcam interfaces to 5 watts if they are all Class 1 PDs.
The following commands assign a power level to webcam ports:
ERS-8310:5(config)#
interface fastEthernet 7/15-7/20
ERS-8310:5(config-if)#
poe limit slot 5
The Avaya Ethernet Routing Switch 8300 software automatically adds one
additional watt to the power limit to cover possible additional power loss between
the PD and the PSE. Therefore, you may notice that the run-time port power
consumption is higher than the configured power limit (the run-time port power
consumption should always be less than the configured power limit + 1 W).
The following command identifies the type of device that is connected to this port:
ERS-8310:5(config-if)#
poe type webcam
You can set the priority for power allocation for PoE card slots and ports. The priority
choices are low, high, or critical. The default priority setting for slots or ports is low.
During a power cycle, the power allocation is determined by the slot priority and port
priority.
Because the default priority setting for ports is low, in this configuration example
you need not configure the Wireless AP ports 8/1 to 8/18.
The following commands set the PoE priority as critical for the VoIP PD interfaces
and high for the webcam interfaces:
