Cisco Systems MGX 8230 manual Cnfchanmap channum chanType FECN/EFCI DE to CLP CLP to DE

Chapter 6 Card and Service Configuration

Configuring Frame Relay Service

–NodeName.SlotNo.PortNo.VPI.VCI for ATM end point. Where ControllerId can be 1 (PAR), 2 (PNNI), or 3 (TAG)

Step 2 Modify a connection as needed by executing cnfcon. See the command line Help or the command reference for the parameters for individual card types.

Step 3 If necessary, modify the CLP and congestion indicator fields by using cnfchanmap. Use dspchanmap to check this configuration for a connection.

cnfchanmap <chan_num> <chanType> <FECN/EFCI> <DE to CLP> <CLP to DE>

•chan_num is the channel (connection) number. The ranges are:

–2CT3, 16–4015

–2T3, 2E3, HS2, 16–2015

–HS1, 16–215

–T1, E1, 16–1015

•chanType is a number in the range 1–5 indicating the service type for the connection.

–1=NIW

–2=SIW in transparent mode

–3=SIW in translation mode

–4=FUNI

–5=frame forwarding

•FECN/EFCI is a number in the range 1–2 that specifies the mapping between FECN and EFCI fields.

–1=map EFCI (SIW only)

–2=set EFCI to 0

•DE to CLP is a number in the range 1–3 that specifies the DE to CLP mapping.

–1=map DE to CLP

–2=set CLP to 0

–3=set CLP to 1

•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)

Step 4 To check statistics for a connection, use dspchstats as needed.

Step 5 Use cnfchanstdabr to configure the parameters for standard ABR (TM 4.0), if necessary:
