dot11TwentyMHzFrameTransmittedCount
Module: IEEE802dot11-MIB
OID (symbolic): IEEE802dot11-MIB::dot11TwentyMHzFrameTransmittedCount
OID (numeric): 1.2.840.10036.2.2.1.39
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description:
This counter shall be incremented when a Frame is transmitted only on the primary channel.
What is dot11TwentyMHzFrameTransmittedCount?
This OID holds a counter that increments each time a wireless frame is transmitted using only the primary 20 MHz channel (without channel bonding), tracking narrowband transmissions. It measures how often the wireless radio transmits in 'normal' single-channel mode versus wider bonded channels. A WiFi engineer would examine this counter to understand whether their 802.11n/ac network is using channel bonding efficiently or mostly sending data on single channels.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.2.840.10036.2.2.1.39 snmpwalk -v2c -c public <target> IEEE802dot11-MIB::dot11TwentyMHzFrameTransmittedCount
Get a specific instance (index 1):

SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> dot11TwentyMHzFrameTransmittedCount.1
