ALM-3276800114 Co-Channel Interference Between APs Was Detected

Description

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

Co-channel interference between APs was detected.

Attribute

Alarm ID	Alarm Severity	Alarm Type
3276800114	Warning	Equipment alarm

Parameters

Name	Meaning
oid	Indicates the MIB object ID of the alarm.
APMAC	Indicates the MAC address of an AP.
APName	Indicates the AP name.
RadioID	Indicates the radio ID.
APChannel	Indicates the channel of a monitoring AP.
APID	Indicates the AP ID.
BssId	Indicates the BSSID 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 co-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 Co-channel frequency interference threshold(%) and check whether the alarm threshold for co-channel interference is configured properly. It is recommended that you set the alarm threshold for co-channel interference to 50.
- If so, go to Step 3.
- If not, go to Step 2.
Run the interference co-channel threshold threshold-value command to configure a proper alarm threshold for co-channel interference. Then, check whether the alarm persists.
- If the alarm persists, go to Step 3.
- If the alarm is cleared, 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 the alarm persists, go to Step 4.
- If the alarm is cleared, go to Step 5.
Collect alarm messages, log messages, and configurations, and then contact the technical support personnel.
