Policy Configuration
Policy Configuration Overview
The P330 supports QoS (Quality of Service) by using multiple priority levels and 
IEEE 802.1p priority tagging to ensure that data and voice receive the necessary 
levels of service.
The Avaya P330 can enforce QoS policy on routed packets and change their 802.1p 
priority, according to the following criteria:
The packet protocol 
Matching the packet's source or destination IP address to the configured 
priority policy.
Whether the packet source or destination TCP/UDP port number falls within a 
pre-defined range.
In addition, the 802.1p priority of a packet can be modified according to the DSCP 
value in the IP header based on the DSCP-802.1p mapping configured by the user. 
The P330 supports Access Control policy. Access Control rules define how the P330 
should handle routed packets. There are three possible ways to handle such packets:
Forward the packet (Permit operation)
Discard the packet (Deny operation)
Discard the packet and notify the management station (Deny and Notify)
The Avaya P330 can enforce Access Control policy on each routed packet, according 
to the following criteria:
Matching the packet's source or destination IP address to the configured Access 
Control policy.
Determine if the packet protocol and source or destination TCP/UDP port 
number falls within a pre-defined range.
Using the ACK bit of the TCP header.
The P330 uses policy lists containing both Access Control rules and QoS rules. The 
policy lists are ordered by rule indexing. 
The Avaya P330 access control rules are set-up using the Command Line Interface 
and Avaya EZ2Rule central policy management application under Avaya™ MSNM 
(MultiService Network Manager).
