Configuring the P334T-ML for Multilayer Policy

Chapter 11 Avaya P330 Layer 2 Features

TCP/UDP port ranges can only have sizes of 2n, where the lower port of the range is aligned to the range number.

For example, for a range of 32 ports (25), the lower ports can have the value of 32, 64, 96, etc.

This limitation does not apply when the device is in “Router” policy type.

Only L3 rules (based on Src/Dest IP address) will be enforced on IP fragments. Therefore, if an L4 rule is applicable to an IP fragment, the fragment will be dropped.

The following rules are not supported for TCP/UDP port numbers:

“lower then”

“greater then”

If a packet matches a rule with a “permit” action and subsequently a rule with “fwd…” action, the packet’s priority will be changed to the one specified in the second rule, instead of being forwarded with the original priority as per “permit” action

This limitation is relevant only for Layer 2 policy (i.e., when the policy type is “all”).

Configuring the P334T-ML for Multilayer Policy

This section describes the configuration of the P334T-ML for Multilayer Policy functionality.

Configuration Requirements

The following specific requirements impact on the configuration of Multilayer Policy in an Avaya P334T-ML:

Multilayer Policy must be configured separately on each P334T-ML in the stack. This is done by opening a “session” to the module.

If the device Mode is “Layer 2,” the policy commands will appear in the L2 CLI tree; if the Device Mode is “Router,” the commands will appear in the L3 CLI tree.

Policy List validation will be performed during list activation.

A CLI command for policy simulation is available.

Configuration File Management

The following specific requirements impact on the management of the Multilayer Policy configuration file:

Unlike other Layer 2 settings, the Layer 2 policy is not automatically saved in NVRAM. In order to save the Layer 2 or Layer 3 policy configuration, the user must copy the running configuration to the startup configuration file. To do this, use the command copy running-configstartup-config.
