dot11ChannelWidthSwitchCount
Module: IEEE802dot11-MIB
OID (symbolic): IEEE802dot11-MIB::dot11ChannelWidthSwitchCount
OID (numeric): 1.2.840.10036.2.2.1.38
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: This counter shall be increment when the bandwidth used is switched from 20 to 40 or vice-versa.
What is dot11ChannelWidthSwitchCount?
A counter incremented each time the station's operating bandwidth switches between 20 MHz and 40 MHz. Frequent switching flagged by a fast-rising counter can indicate channel contention or interference forcing the radio to fall back to a narrower channel repeatedly.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.2.840.10036.2.2.1.38 snmpwalk -v2c -c public <target> IEEE802dot11-MIB::dot11ChannelWidthSwitchCount
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.2.840.10036.2.2.1.38.1 snmpget -v2c -c public <target> IEEE802dot11-MIB::dot11ChannelWidthSwitchCount.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> dot11ChannelWidthSwitchCount.1
