P333R-LB supports both bridging and two types of routing firewalls: transparent and non-transparent.

Transparent Routing Firewall Load Balancing

This section explains how the P333R-LB supports Transparent Routing FWLB, and includes configuration examples.

Implementation

For Transparent Routing FWLB, the load balancer receives a packet, makes a load balancing decision, and forwards the packet to a firewall. The firewall does not perform Network Address Translation (NAT) on the packets; the source and destination IP addresses are not changed.

Two P333R-LBs are required for Transparent Routing FWLB, one on each side of the firewalls. One device intercepts traffic between the protected zone and the firewall, and the second device intercepts traffic between the unprotected zone and the firewall.

Transparent Routing firewalls act as "next hop" devices from the perspective of the P333R-LB. After one of the firewalls in a group is selected, normal routing to that firewall takes place.

The P333R-LB performs an “intelligent routing” decision, based on the Load Balancing criteria, and replaces the MAC address in the packets by the MAC address of the selected firewall.

P333R-LB enables you to route packets destined to a Demilitarized Zone (DMZ). A DMZ is a portion of the client’s network, apart from the client’s LAN, where remote access is allowed. After creating a DMZ, a third load balancer is installed, which routes packets to the DMZ.

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.
