Make sure the DLCI is not part of a frame relay DLCI backup group. (See page 7-22.) Also make sure that the DLCI is different than the one configured for the physical port in the frame relay PVC record.

Format

is the RFC1490 encapsulation method used for bridged traffic. Note that specifying 8023_TB will add an Ethernet header to the frame, and 8025_SRB will add a Token Ring header.

Bandwidth Allocation Group

assigns the interface to one of sixteen groups whose parameters regulate bandwidth usage. See "Configuring Frame Relay Backup Groups" on page 7-22.

Host MAC Address

is the MAC address of the LLC2 host in the node.

Session Type

if Originated, means that LLC2 connections from the configured Host MAC Address can use this interface. If Terminated, connections to the configured address can use this interface.

LAN ID

identifies the ring number used by a frame relay-compliant source-route bridge at the other end of this PVC. The value is normally assigned by a system administrator.

LAN IDs can also be configured in LLC2/Bridge Node Defaults. Each LAN ID must be unique within the network on which this node will operate.

1800 specifications

Cabletron Systems, a leading player in network management and telecommunications solutions during the late 20th century, introduced several innovative products that played a crucial role in shaping enterprise networking. Among these were the Cabletron FRX6000, FRX4000, and the FRX1800, which delivered advanced features aimed at enhancing network performance, security, and scalability.

The Cabletron FRX6000 was designed as a robust multi-layer switch, ideal for large-scale enterprise environments. It supported extensive routing capabilities, allowing organizations to manage traffic efficiently even under heavy loads. The FRX6000 boasted high throughput rates and low latency, making it suitable for demanding applications. With support for various network protocols, including IP, IPX, and AppleTalk, its adaptability made it a versatile choice for diverse networking needs. Moreover, security features like VLAN support and Access Control Lists (ACLs) provided enhanced protection against potential threats.

Moving to the FRX4000, this model offered a balance between performance and cost-effectiveness. The FRX4000 maintained many of the essential features of its larger counterpart while catering to medium-sized enterprises. It provided Layer 3 routing and could handle multiple simultaneous connections, ensuring seamless communication across departments. The modular design allowed for easy upgrades, enabling businesses to expand their network infrastructure without significant overhauls. This made the FRX4000 an attractive option for organizations looking to optimize their network investments.

Lastly, the FRX1800, designed for small to medium businesses, focused on simplicity and ease of use while still incorporating powerful network management capabilities. Its user-friendly interface made it accessible for organizations lacking extensive IT resources. The FRX1800 provided essential functionalities such as Integrated Layer 2 switching and routing, network monitoring, and basic security features, ensuring that even smaller companies could maintain efficient, reliable networking without overwhelming complexity.

All three models utilized advanced technologies, including a high bandwidth backbone and state-of-the-art switching architecture, to enable fast and reliable data transfer. They also supported Quality of Service (QoS) mechanisms, allowing businesses to prioritize critical applications and ensure consistent performance across the network.

In summary, the Cabletron FRX6000, FRX4000, and FRX1800 were pivotal in enhancing network capabilities, providing organizations with scalable, secure, and high-performance options tailored to their specific needs.
