This read-write enum, when set to reset(3), clears every address table entry learned on this specific port in addition to zeroing its traffic counters and reset timer, a more thorough reset than ciscoTsPortCfgResetStats alone. An admin would use this after physically moving which stations connect to a port, forcing the switch to relearn from scratch rather than carrying stale MAC-to-port mappings that could misdirect traffic. This is the right tool when a port's forwarding behavior seems wrong specifically because of outdated learned addresses, not just to reset counters.
