ALM-3276800115 Adjacent Channel Interference Between APs Was Detected

Description

WLAN/4/AP_ADJACENT_CHANNEL_INTERFERENCE: OID [OID] The adjacent-channel interference exceeds the alarm threshold.(APMAC=[OPAQUE], RadioID=[INTEGER],APName=[OCTET], APChannel=[INTEGER], APID=[INTEGER], IntfBssId=[OPAQUE], IntfChnl=[INTEGER], RSSI threshold percent=[INTEGER]%)

Adjacent-channel interference between APs was detected.

Attribute

Alarm ID	Alarm Severity	Alarm Type
3276800115	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.
APChannel	Indicates the channel of a monitoring AP.
APID	Indicates the AP ID.
IntfBssId	Indicates the BSSID of the interfering AP.
IntfChnl	Indicates the channel of the interfering AP.
RSSI threshold percent	Indicates the RSSI threshold value on an interface, in percentage.

Impact on the System

The packet loss rate increases, the data rate decreases, and even the services may be interrupted.

Possible Causes

The alarm threshold for adjacent-channel interference was exceeded.

Procedure

Run the display radio-2g-profile { all | name profile-name } and display radio-5g-profile { all | name profile-name } commands to view the value of Adjacent-channel frequency interference threshold(%) and check whether the alarm threshold for adjacent-channel interference is configured properly. It is recommended that you set the alarm threshold for adjacent-channel interference to 50.
- If so, go to Step 3.
- If not, go to Step 2.
Run the interference adjacent-channel threshold threshold-value command to configure a proper alarm threshold for adjacent-channel interference. Then, check whether the alarm persists.
- If so, go to Step 3.
- If not, go to Step 5.
If severe interference triggers local radio calibration, the channel and power are adjusted automatically. Then, check whether the alarm persists.
- If so, go to Step 4.
- If not, go to Step 5.
Collect alarm messages, log messages, and configurations, and then contact the technical support personnel.
