Chapter 6 Card and Service Configuration

Configuring Frame Relay Service

cnfchanstdabr <Port.DLCI/CHAN_NUM> <mcr> <pcr> <icr> <rif> <rdf> <nrm> <trm> <tbe> <frtt> <adtf> <cdf>

Please note the following:

Standard ABR is a connection-level feature that requires the Rate Control Feature to be enabled on the card.

Standard ABR does not support Explicit Rate (ER) marking of RM cells.

cnfconabrrates can be used to modify the rates:

Usage: cnfconabrrates <Port.Vpi.Vci/Chan_Num> <mcr> <pcr> <icr>

cnfconabrparams can be used to modify the parameters.

Usage: cnfconabrparams <Port.Vpi.Vci/Chan_num> <ABRType> <rif> <rdf> <nrm> <trm> <tbe> <rtt> <adtf>
