What is mnMacAddressesRemoved?

This read-only counter tracks the total number of MAC addresses removed from the device's forwarding database. An admin compares this counter against mnMacAddressesLearnt over time to understand MAC table churn, which can indicate aging timeouts, link flaps, or unstable end-station connectivity. For example, a steadily climbing mnMacAddressesRemoved count alongside frequent learns on the same ports may point to a flapping uplink or a misbehaving host.
