The ac protect link-switch packet-loss echo-probe-time command specifies the number of Echo packets sent within a statistics collection interval.
The undo ac protect link-switch packet-loss echo-probe-time command restores the default number of Echo packets sent within a statistics collection interval.
By default, the number of Echo packets sent within a statistics collection interval is 20.

Usage Scenario
When the active/standby link switchover mode is set to the network stabilization mode, ACs periodically check whether the network stabilization of active and standby links meets the condition for triggering an active/standby link switchover and collect statistics about the specified number of Echo packets at each interval to calculate the network stabilization.
In N+1 backup scenarios, only one of the primary and backup ACs sets up a CAPWAP link with an AP at the same time. The network stabilization of this link can be calculated through Echo packets. The network stabilization of the link between the AP and another AC can be calculated through Primary Discovery packets. Statistics about Primary Discovery packets can also be collected by setting the parameter echo-probe-time.
Prerequisites
The ac protect link-switch mode network-stabilization command has been run to set the active/standby link switchover mode to the network stabilization mode.
