Avaya P130 manual Policy Networking, Policy Rules and Filters

Chapter 6 Avaya P130 CLI

Policy Networking

The P130 is a policy workgroup switch which provides advanced policy-based networking at the edge of your network. The P130 implements Policy rules based on Layer 3 and Layer 4 header information. The policies are used to modify the Class of Service (CoS) of IP packets, which are sent by locally attached stations.

Policy Rules and Filters

Policy rules allow the user to define filtering rules which modify packet priority. Each packet is evaluated against a set of rules. The following criteria are used to develop rules:

•Source IP address

•Source IP address host mask

•Destination IP address

•Destination IP address host mask

•Protocol type

•Layer 4 source port range

•Layer 4 destination port range

•DSCP word

•TCP Ack Bit

There are 3 ways to define Policy rules:

•Locally using CLI commands

•Via the MultiService Network Manager EZ2Rule Policy Manager

•Via the Avaya policy application.

Using Policy Lists

•The P130 supports up to 128 policy rules from up to 8 policy rule types (i.e. Filters).

•You can configure up to 2 Policy Lists in a P130 module. Only one of them can be used as the Active List, while the other one is dormant.

•You can edit only the dormant rules list.

Note: Multilayer Policy support, beyond the basic P130 Layer 2 switch features requires a license key for activation. If no Multilayer Policy License Key was entered to the P130 switch, the Policy commands will not be activated.
