What is cmIpFlushARPCacheAction?
This read-write action object triggers a flush of the device's ARP cache when set to the appropriate action value. Admins use this to force stale or incorrect IP-to-MAC mappings to be cleared, which is useful after a network change when devices' MAC addresses have moved. For example, after re-IPing a subnet, an admin would set this object to initiate the flush so the device relearns fresh ARP entries instead of using outdated cached mappings.
