This object sets, for a specific interface and protocol, how often the device checks whether that interface is still under DoS attack, removing it from the blacklist if the attack has stopped, overriding the global setting for that interface. Admins use it to customize the recheck interval for a particular interface known to need different handling than the global default. For example, an admin might shorten this on a critical interface to restore it from the blacklist more quickly once an attack subsides.
