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.
