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>
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:
• 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)
