Name Meaning
OID Indicates the ID of the MIB object.
APMAC Indicates the MAC address of an AP.
RadioID Indicates the radio ID.
ApName Indicates the AP name.
APID Indicates the AP ID.

Impact on the System

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

Possible Causes

Devices, except for the co-channel APs, adjacent-channel APs, and STAs, worked on the AP channel and interfered with the AP.


  1. No action is required.

    If severe interference deteriorates the environment, it will trigger local radio calibration, and the APs will automatically adjust the channel and power. Then, check whether the alarm persists.

    • If so, go to Step 2.
    • If not, go to Step 3.

  2. Collect alarm messages, log messages, and configurations, and then contact the technical support personnel.
  3. End.
