atmSuPortAtmCnfgShapingMode
Module: ACE20-MIB
OID (symbolic): ACE20-MIB::atmSuPortAtmCnfgShapingMode
OID (numeric): 1.3.6.1.4.1.164.12.4.2.3.1.1.9
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: ATM Shaping mode. Three possible values: SW Shaping. HW Shaping - APC with NCITS = 1. HW Shaping - APC with NCITS = 2 The difference between the two hardware modes is in the connection cell granularity and maximum bandwidth (BW): * For NCITS=1, the granularity is of one cell and the max. BW is the uplink BW, * For NCITS=2, the granularity is of every two cells and the max. BW is half of the uplink BW.
What is atmSuPortAtmCnfgShapingMode?
This OID selects between software traffic shaping and hardware shaping (with either 1-cell or 2-cell granularity) to control ATM bandwidth allocation. Network engineers choose based on their line rate and precision requirements: software is flexible but slower, while 2-cell granularity trades bit-level precision for higher efficiency. For example, choosing 'HW Shaping with 2-cell granularity' on a high-speed OC-3 line achieves near-line-rate throughput with acceptable bandwidth accuracy.
