Policy-Enabled Networking; Power Over Ethernet - Avaya 4524GT Configuration Manual

System configuration fundamentals

Policy-enabled networking

With the policy-enabled networking, you can implement classes of services and assign priority
levels to different types of traffic. You can also configure policies to monitor the characteristics
of traffic.
For example, in policy-enabled networking, you can determine the sources, destinations, and
protocols used by the traffic. You can also perform a controlling action on the traffic when certain
user-defined characteristics match.
The policy-enabled networking; supports Differentiated Services (DiffServ). DiffServ is a
network architecture through which service providers and enterprise network environments
can offer various levels of services for different types of data traffic.
You can use DiffServ Quality of Service (QoS) to designate a specific level of performance on
a packet-by-packet basis. If you have applications that require high performance and reliable
service, such as voice and video over IP, you can use DiffServ to give preferential treatment
to this data over other traffic.

Power over Ethernet

The Power over Ethernet; POE45GT; and the 4526GTX-PWR (PoE switches) provide IEEE
802.3af-compliant power or PoE on all 10/100/1000 RJ-45 ports.
The Power over Ethernet; 4526T-PWR and the 4550T-PWR (PoE switches) provide IEEE
802.3af-compliant power or PoE on all 10/100 RJ-45 ports.
PoE refers to the ability of the switch to power network devices over an Ethernet cable. Some
of these devices include IP Phones, Wireless LAN Access Points, security cameras, and
access control points.
The PoE switches automatically detect the network device requirements and dynamically
supply the required DC voltage at a set current to each appliance.
To configure and manage the PoE features, you must use either ACLI or EDM.
Important:
You must use a four-pair Category 5 UTP cable for PoE. A standard two-pair UTP Cable
does not support PoE.
