atmIfVccBandwidthReduction

Module: Nortel-Magellan-Passport-AtmCoreMIB

OID (symbolic): Nortel-Magellan-Passport-AtmCoreMIB::atmIfVccBandwidthReduction

OID (numeric): 1.3.6.1.4.1.562.2.4.1.114.5.130.1.100

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: This attribute is HISTORICAL. Please refer to the attribute of the same name in the group AtmTmOper.

This attribute shows the amount by which the bandwidth has been reduced for this connection. This value is non-zero only for connections which have bandwidthElastic displayed as yes, and which are also operating in a reduced bandwidth mode. This is typically be the case for selected connections running over an IMA link. This attribute takes a value from 0 (no reduction) up to the ECR. All connections which are running at their full allocated bandwidth, bwReduction have the value 0. Connections which have been reduced in allocated bandwidth have a positive number for this attribute. The bwReduction may be subtracted from the ECR (which is displayed as txTrafficDescParm 5) to determine the actual bandwidth allocated to this connection.
