This read-only DisplayString records the last time an operator or process explicitly cleared the counters in the most recently completed 24-hour bin, frozen once the day rolled over in this IGMP snooping/proxy PM table. Admins check it before trusting a low counter value on this instance — a recent clear explains a suspiciously small reading, versus a long-uncleared bin where a low value means genuinely quiet traffic, since it is the metadata field for the most recently completed 24-hour bin, frozen once the day rolled over in this IGMP snooping/proxy PM table. For the most recently completed 24-hour bin, frozen once the day rolled over in this IGMP snooping/proxy PM table, this might read a value like "2026-07-09,10:36:00", which an admin lines up against a customer-reported outage window to see if it falls inside or outside this bin.
