Configuring Frame Relay Service

CLP to DE is a number in the range 1–4 that specifies the CLP to DE mapping.

1=map CLP to DE 2=set DE to 0 3=set DE to 1 4=ignore CLP (NIW only)

Establishing the BPX 8600-to-BPX 8600-Series Segment

For a three-segment connection, establish a BPX 8600-to-BPX 8600-series (middle) segment. Execute addcon at one of the BPX 8600-series nodes, as follows.

•For slot and port number, specify slot and port of the BXM connected to MGX 8850 node.

•For VPI and VCI, specify the VPI and VCI at the endpoint on the PXM.

•For Nodename, use the name of the BPX 8600-series switch at the far end of the connection.

•For Remote Channel, specify the slot and port number of the BXM port attached to the MGX 8850 node at the far end. Specify the VPI as the slot number of the remote MGX 8850 FRSM connected to the BPX 8600-series switch, and specify VCI as the LCN of the Frame Relay connection at the remote MGX 8850 node.

•Specify the type of connection. Enter ATFST if the ForeSight feature is operating and ATFR if this feature is not operating.

Specify the other addcon bandwidth parameters such as MCR, PCR, %Util, and so on.

•

Minimum Cell Rate (MCR) is only used with the ForeSight feature (ATFST connections).

MCR and Peak Cell Rated (PCR) should be specified according to the following formulae.

MCR=CIR *3/800 cells per second.

•PCR=AR * 3/800 cells per second but less than or equal to 6000. AR=Frame Relay port speed in bps. For example,

For example:

AR equals 64K, PCR=237, or

 

AR speed equals 256K, PCR=950, or

 

AR speed equals 1536K, PCR=5703

The preceding MCR and PCR formulae are predicated on a relatively small frame size of 100 octets, and even smaller frame sizes can result in worse-case scenarios. For example:

For a frame size of 64 octects the PCR formula becomes: PCR=AR * 2/512 cells per sec

For a frame size of 43 octects the PCR formula becomes: PCR=AR * 2/344 cells per sec

% Util should be set to the same value as that used for the Frame Relay segments of the connection.

Test Commands for the FRSMs

Use the display commands (dsp...) for checking the state of cards, lines, ports, queues, and connections. The following commands are available for testing the FRSMs (see the Cisco MGX 8850 Wide Area Edge Switch Command Reference for descriptions):

•addlnloop, cnflnloop, and dellnloop are line-level, diagnostic commands that require the service level user privilege.

MGX-FRSM-HS2, MGX-FRSM-2T3E3, MGX-FRSM-2CT3 specifications

Cisco Systems is a leader in networking technology and infrastructure, providing solutions that drive innovation and efficiency for businesses worldwide. Among its diverse range of products, the MGX series stands out as a pivotal component for the network-centric era, especially with models like MGX-FRSM-2CT3, MGX-FRSM-2T3E3, and MGX-FRSM-HS2. These modules are primarily designed for the MGX 8800 series routers, facilitating efficient traffic management and service delivery.

The MGX-FRSM-2CT3 is a versatile module that supports two T3 connections. It allows network operators to seamlessly integrate high-capacity circuit-switched and packet-switched data on a unified platform. This versatility is crucial for service providers looking to enhance their bandwidth offerings while ensuring reliable performance across voice, video, and data applications.

In contrast, the MGX-FRSM-2T3E3 module caters to operators needing E3 support. This feature allows for efficient data transport over a broader bandwidth, catering to European standards. The E3 configuration is vital for service providers operating in Europe or regions that utilize E3 technology prominently.

The MGX-FRSM-HS2 module is another significant offering, designed to accommodate the increasing demand for high speed and high capacity. It supports higher-order TDM and packet technologies, enabling operators to implement advanced services such as VoIP, video conferencing, and other data-intensive applications. This module provides scalability and reliability, making it ideal for next-generation networks.

All three modules leverage Cisco’s advanced switching and routing technology, ensuring optimal performance and minimal latency. The integration of Quality of Service (QoS) features allows network administrators to prioritize traffic types effectively, ensuring mission-critical applications receive the necessary bandwidth.

Additionally, these MGX modules support various signaling protocols, enabling interoperability with existing network infrastructure while also facilitating the migration to newer technologies. They play an essential role in modernizing telecom networks, allowing service providers to adapt to changing market demands and technology landscapes.

In summary, the Cisco MGX-FRSM-2CT3, MGX-FRSM-2T3E3, and MGX-FRSM-HS2 modules are key components for businesses looking to enhance their networking capabilities. With their robust support for T3 and E3 technologies, high scalability, and advanced QoS features, these modules empower service providers to deliver a wide range of services, drive innovation, and meet the growing demands of users in an increasingly connected world.
