apWMMBssParamCWmin
Module: CTRON-AP3000-MIB
OID (symbolic): CTRON-AP3000-MIB::apWMMBssParamCWmin
OID (numeric): 1.3.6.1.4.1.52.4.13.23.2.1.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This attribute shall specify the value of the minimum size of the window in the exponent form that shall be used by a QSTA for a particular AC for generating a random number for the backoff.
What is apWMMBssParamCWmin?
This read-write integer (1-15) is the exponent form of the minimum contention window that non-AP QSTAs use, for a given Access Category, when computing their backoff random number. A smaller CWmin gives that traffic class faster, more aggressive channel access at the cost of more collisions under load. An admin tuning voice quality might lower this value for the voice AC's BSS parameter so client phones win channel access more often.
