Frame Relay Port Parameters

Table 7-3 Frame Relay Port Parameters

Parameter	Valid Values		Default Value


Port Type	Fram e Relay		not valid here

Physical Port Interface	see explanation		see explanation

Blocked Port Flag	Y/N 1		N
Line Speed (bits per sec)	see explanation		9600 2
Maximum Bytes per Frame	16–4096		1600

Logical DCE	Y/N 3		Y
Generate Clock 4	Y/N		Y
Rcv Clock (TT) from DTE 4,5	Y/N		N
CSU/DSU Operating Mode 6	Normal/LDM		Norm al

RTS Control 6	Constant/External		Constant
Link Layer Management	None, LMI, ANNEXD		None

N1 Polling Count 7	1–6		6
N2 Error Threshold 7	1–10	8	2 if LMI 9
N2 Error Threshold 7	1–10	8	3 if Annex D 9
			3 if Annex D 9
N3 Monitored Events Count 7	1–10	8	4
T1 Link Integr ity Timer (sec) 7	5–30	10	10
T2 Polling Verification Tim er (sec) 11	5–30	10	15
Enable Outgoing Rate Control	Y/N		N

Enable Bandwidth Allocation	Y/N		N

For Backup Use Only?	Y/N		N

Automatic DCE	Y/N		N

1If set to Y, no backup DLCIs on this port will be used (even if the port is enabled via on-line port enable).

2If one physical frame relay port will connect to several remote sites, be sure the line speed is adequately higher that the speeds configured on the remote sites.

3If this port will connect to a frame relay network, set Logical DCE to N. Also note that one end of a frame relay backup connection must be configured as logical DCE.

4Not applicable to CSU/DSU ports.

5This parameter is relevant only if Physical Port Interface is something other than RS- 232 and Generate Clockis Y.

6Applicable only to CSU/DSU ports.

7These parameters are relevant only if Link Layer Management is LMI or ANNEXD and

Logical DCE is N.

8N3 should be greater than or equal to N2.

9If Link Layer Management is none, this parameter is irrelevant. (If Link Layer Man- agement is changed to none from some other value, the default for N2 will be left as it was before the change.)

10T2 should be greater than or equal to T1.

11This parameter is relevant only if Logical DCE is Y.

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.
