(Optional) Configuring CAPWAP Heartbeat Detection
Context
As defined by CAPWAP, an AP and AC periodically exchange packets to maintain connectivity of the data channel and management channel. If the AP or AC does not receive any response from each other after CAPWAP heartbeat packets are sent for the specified number of times, the AP and AC consider the link between them disconnected.
Perform the following configurations on the active and standby ACs:
Procedure
- Run system-view
The system view is displayed.
- Run capwap echo { interval interval-value | times times-value } *
The CAPWAP heartbeat detection interval and number of heartbeat packet transmissions are configured.
By default, the CAPWAP heartbeat detection interval is 25s and the number of CAPWAP heartbeat detections is 6.
By default, If dual-link backup is enabled, the CAPWAP heartbeat detection interval is 25s and the number of CAPWAP heartbeat detections is 3.
If you set the CAPWAP heartbeat detection interval and the number of CAPWAP heartbeat detections smaller than the default values, the CAPWAP link reliability is degraded. Exercise caution when you set the values. The default values are recommended.
