What is smtCWMin?
This sets the 802.11 CWMin (minimum contention window) value, which must be a power of two minus one. Admins tune this to adjust how aggressively the radio starts its backoff timer before transmitting, affecting collision behavior on a busy wireless channel.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.232.145.1.2.1.20 snmpwalk -v2c -c public <target> WL400-DOT11EXT-MIB::smtCWMin
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.232.145.1.2.1.20.1 snmpget -v2c -c public <target> WL400-DOT11EXT-MIB::smtCWMin.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.232.145.1.2.1.20.1 i <value>
