dot11TwentyMHzFrameReceivedCount
Module: IEEE802dot11-MIB
OID (symbolic): IEEE802dot11-MIB::dot11TwentyMHzFrameReceivedCount
OID (numeric): 1.2.840.10036.2.2.1.41
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: This counter shall be incremented when a Frame is received only on the primary channel.
What is dot11TwentyMHzFrameReceivedCount?
A counter incremented when a frame is received only on the primary 20 MHz channel, even though the station supports 40 MHz operation. A high ratio of this counter to total received frames suggests the link is frequently falling back to narrowband operation.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.2.840.10036.2.2.1.41 snmpwalk -v2c -c public <target> IEEE802dot11-MIB::dot11TwentyMHzFrameReceivedCount
Get a specific instance (index 1):
