clear alert
The clear alert command removes an alert based on the alert's ID number from the clear alert list. Alerts are cleared based on a single ID, a list of IDs, or all at once. A maximum of 64 alert IDs can be removed at one time.
You may want to clear alerts that have already been acknowledged and resolved while keeping alerts for issues that are still pending.
clear alert <AlertID|AlertList|all>
The ID of the alert you want to clear. For example, 10.
