WLAN/4/RADIO_ENV_DETERIORATE:OID [OID] Radio signal environment deteriorates. (APMAC=[OPAQUE],RadioID=[INTEGER], APName=[OCTET], PER=[INTEGER]%, ConflictRate=[INTEGER]%, APID=[INTEGER], NoiseFloor=[INTEGER]dBm, Reason=[OCTET], BadChannel=[INTEGER])

The radio signal environment deteriorated.

Attribute

Alarm ID	Alarm Severity	Alarm Type
3276800073	Warning	Equipment alarm

Parameters

Name	Meaning
OID	Indicates the MIB object ID of the alarm.
APMAC	Indicates the MAC address of an AP.
RadioID	Indicates the radio ID.
APName	Indicates the AP name.
PER	Indicates the packet error rate on the wireless-side interface.
ConflictRate	Indicates the collision rate of a radio.
APID	Indicates the AP ID.
NoiseFloor	Indicates the noise floor value detected in the current environment.
Reason	Indicates the noise floor generation reason.
BadChannel	Indicates the bad channel.

Impact on the System

The deterioration of the radio signal environment will increase the packet loss rate, reduce the transmission rate, or even interrupt services.

Possible Causes

The radio signal environment deteriorated.

Procedure

Run the display ap neighbor command to view the neighboring radio, and check whether there are APs using the same or neighboring radio.
- If so, run the channel command to reconfigure a channel or power for this radio to avoid the signal interference. Then go to Step 2.
- If not, go to Step 3.
Check whether a radio signal environment restoration alarm is generated.
- If so, go to Step 6.
- If not, go to Step 3.
Check whether there are devices that interfere with the radio signal or make noises.
- If so, remove these devices and then go to Step 4.
- If not, go to Step 5.
Check whether a radio signal environment restoration alarm is generated.
- If so, go to Step 6.
- If not, go to Step 5.
Collect the alarm information, log information, and configuration information, and then contact technical support personnel.
End.
