OID (symbolic): Nortel-MsCarrier-MscPassport-AtmCoreMIB::mscAtmIfCAAbrRateDecreaseFactor

OID (numeric): 1.3.6.1.4.1.562.36.2.1.114.3.5.100.1.24

Node type: OBJECT-TYPE

Access: read-write

Description: This attribute specifies the default Rate Decrease Factor (RDF) for ABR connections. An override to this default may be specified for a provisioned connection under the Vcd Tm Abr or Vpd Tm Abr component, or signalled in the ABR Setup Parameters Information Element.

The RDF value is computed by using the provisioned value of this attribute, n, as 2 to the inverse power n. For example, if the value of this attribute is 8, RDF is 2E-8 = 1/256.

RDF controls the amount by which the cell transmission rate may decrease upon receipt of a backward Resource Management (B- RM) cell. For example, if a backward RM cell is received with the Congestion Indication (CI) field set to 1, the Allowed Cell Rate (ACR) value would be reduced by the amount (RDF*ACR). The ACR is not allowed to fall below the Minimum Cell Rate (MCR), in which case the ACR is set to MCR.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.562.36.2.1.114.3.5.100.1.24
snmpwalk -v2c -c public <target> Nortel-MsCarrier-MscPassport-AtmCoreMIB::mscAtmIfCAAbrRateDecreaseFactor

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.562.36.2.1.114.3.5.100.1.24.1
snmpget -v2c -c public <target> Nortel-MsCarrier-MscPassport-AtmCoreMIB::mscAtmIfCAAbrRateDecreaseFactor.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.562.36.2.1.114.3.5.100.1.24.1 i <value>
