Chapter 7 Establishing Switch Access

Establishing a Modem (PPP) Connection with the P330

Overview

Point-to-Point Protocol (PPP) provides a Layer 2 method for transporting multi- protocol datagrams over modem links.

Connecting a Modem to the Console Port

A PPP connection with a modem can be established only after the Avaya P330 is configured with an IP address and net-mask, and the PPP parameters used in the Avaya P330 are compatible with the modem’s PPP parameters.

1Connect a terminal to the console port of the Avaya P330 switch as described in Connecting a Terminal to the Avaya P330 Serial port.

2When you are prompted for a Login Name, enter the default name root.

3When you are prompted for a password, enter the password root. You are now in Supervisor Level.

4At the prompt, type:

set interface ppp <ip_addr><net-mask>

with an IP address and netmask to be used by the Avaya P330 to connect via its PPP interface.

Note: The PPP interface configured with the set interface ppp command must be on a different subnet from the stack inband interface.

5Set the baud rate, ppp authentication, and ppp time out required to match your modem. These commands are described in the “Command Line Interface” chapter.

6At the prompt, type:

set interface ppp enable

The CLI responds with the following:

Entering the Modem mode within 60 seconds...

Please check that the proprietary modem cable is plugged into the console port

7Use the DB-25 to RJ-45 connector to plug the console cable to the modem’s DB- 25 connector. Plug the other end of the cable RJ-45 connector to the

Avaya P330 console’s RJ-45 port.

8The Avaya P330 enters modem mode.

9You can now dial into the switch from a remote station, and open a Telnet session to the PPP interface IP address.

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.
