interference detect-enable
Function
The interference detect-enable command enables interference detection.
The undo interference detect-enable command disables interference detection.
By default, interference detection is disabled.
Usage Guidelines
WLAN wireless channels are vulnerable to interference in surrounding radio environments, and the service quality is therefore degraded. If interference detection is configured, a monitor AP can know the radio environment in real time and report alarms to the AC in a timely manner.
Interference detection enables an AP to
detect AP co-channel interference, AP adjacent-channel interference,
and STA interference.
- AP co-channel interference: Two APs working on the same frequency band interfere with each other. For example, on a large-scale WLAN (a university campus network), different APs often use the same channel. When there are overlapping areas among these APs, co-channel interference exists, degrading network performance.
- AP adjacent-channel interference: Two APs with different center frequencies have overlapping areas, resulting in adjacent-channel interference. Therefore, if APs are placed too close to each other or they have strong signals, more noise will be produced, degrading network performance.
- STA interference: If there are many STAs that are managed by other APs around an AP, services of the STAs managed by the local AP may be affected.
