Chapter 12 Avaya P330 Layer 3 Features

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).

P333R-LB specifications

The Avaya P333R-LB is a robust and versatile switch that is part of Avaya's portfolio aimed at enterprise networking solutions. This switch is designed to enhance the performance and scalability of network infrastructure while ensuring high availability and reliability.

One of the main features of the P333R-LB is its Layer 3 switching capability, which allows for efficient routing within an organization's network. This capability is particularly beneficial for organizations with multiple VLANs, as it simplifies the routing process and ensures that data packets are transmitted in the most efficient manner possible.

The P333R-LB is equipped with advanced Quality of Service (QoS) features to prioritize traffic based on the type of application being used. This ensures that critical applications, such as VoIP and video conferencing, receive the necessary bandwidth and low latency required for optimal performance. Additionally, it supports both IPv4 and IPv6 protocols, making it adaptable to a variety of networking environments.

Another important feature of the Avaya P333R-LB is its stackable design. This allows multiple switches to be interconnected, creating a single logical unit. This stacking capability not only simplifies management but also increases overall network capacity and redundancy. In case of a hardware failure, the stack can continue operating without interruption, maintaining network integrity and service continuity.

The switch also integrates advanced security features, including support for MAC filtering, access control lists, and port security. These features help to safeguard network resources from unauthorized access and potential threats. Moreover, the P333R-LB supports 802.1X port-based authentication, which adds an additional layer of security during user access to the network.

The Avaya P333R-LB comes with multiple Gigabit Ethernet ports, allowing for high-speed connectivity to devices such as servers, workstations, and IP phones. This ensures that all devices on the network can communicate effectively, supporting the demands of modern enterprise environments.

For management and monitoring, the P333R-LB offers a user-friendly web interface along with SNMP support, enabling network administrators to easily configure settings and monitor network performance. This simplicity in management is crucial for IT teams that need to ensure optimal network performance while minimizing downtime.

In summary, the Avaya P333R-LB is a feature-rich, scalable, and reliable switch that meets the needs of demanding enterprise networks. With its advanced technologies, QoS support, stackable design, robust security features, and high-speed connectivity options, the P333R-LB is positioned to support a wide range of applications and enhance overall network performance.
