Policy Configuration
Policy Configuration Overview
The C360 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 C360 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 C360 supports Access Control policy. Access Control rules define how the C360 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 C360 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 C360 uses policy lists containing both Access Control rules and QoS rules. The policy lists
are ordered by rule indexing.

Tip:
Use the Command Line Interface and the Avaya central policy management
application under Avaya Integrated Management to set up the C360 access
control rules
