Chapter 11 Avaya P330 Layer 2 Features

MAC Security

The MAC security function is intended to filter incoming frames (from the line) with an unauthorized source MAC address (SA).

MAC Security Implementation in P330

When a frame is received on a secured port, its SA is checked against the MAC Address Table. If either the SA is not found there, or it is found but with a different port location, then the frame is rejected without being learned. A message is then sent to the CPU.

The Agent reports the attempted intrusion via an SNMP security violation trap containing the intruder's MAC address. To prevent the flooding of the Console's trap log / network, the Agent sends an intruder alert every 5 seconds for the first 3 times a specific intruder is detected on a port, and then every 15 minutes if the intrusion continues.

User should first enable the MAC security global mode (set security mode) and then configure the ports which should be secured (set port security). When setting a port to secured, the MAC addresses that a currently learnt on this port are preserved and considered as secure MAC, unless they are removed using clear secure mac command. Individual secure MACs can also be added.

Note: If the secure MAC editing command are to be implemented on a switch other than the stack master, a session should be opened to the relevant switch.

Note: Ports that are members of a port redundency scheme should not be also configured as secure ports.

MAC Security CLI Commands

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.
