LLC2 Interface Parameters

The following table lists parameters for all interface types. Explanations of some parameters follow the table.

Table 9-5 Bridge Port/LLC2 Interface Parameters

Parameter	Valid Values	Default Value


Interface Type	Ethernet, TokenRing, FRL	FRL (frame relay)

Blocked Port Flag	Y/N	N

Port Priority:Native LLC2 format:	n/a
8025_SRB/8023_TB format:	0–255	128

Path Cost: Native LLC2 format:	n/a
8025_SRB/8023_TB format:	1/1000 FR port line speed	15625

Pr iority	0–9	0

LAN Card	n/a	0

RLP	n/a	0

Port	0–7 1	0
DLCI	16–991 2	16
Format	Native LLC2,8025_SRB,
	8023_TB 3	Native LLC2
Bandwidth Allocation Group	1–16	1

Host MAC Address	valid host address 4	400000000001
Session Type	Originated, Terminated	Originated

LAN ID	000–fff (hex) 5	fff

1Make sure the port is not configured for backup use only. (See page 7-18.)

2Make sure the DLCI is not part of a frame relay DLCI backup group or part of a frame relay PVC (both described in Chapter 7).

3See caution at explanation.

4Configured in LLC2 Host file (described on page 9-18). If the address was bit-swapped in the Host record, it must also be bit-swapped here.

5The LAN ID on an originated LLC2 interface must match the LAN ID on the corre- sponding terminated interface. Also, (other than the exception of originated/terminated pairs) each LAN ID must be unique among all LAN IDs throughout the network on which this node will operate.

Interface Type

identifies whether the interface is on a LAN or a frame relay network.

Blocked Port Flag

will cause the port to be enabled (N) or disabled (Y) at node IPL. The interface will remain in that state until this parameter is changed or (frame relay interface only) an on-line enable ([B], [B], [C] from the Main Menu) or disable ([B], [B], [A] from the Main Menu) is performed.

Port Priority

will become the first octet of the Port ID field in Spanning Tree Protocol messages. The lower the number, the higher the priority that the interface will be given among other interfaces in the spanning tree.

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.
