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>
