What is jnxMacAddressesRemoved?
This is a running count of MAC addresses that have been removed, typically aged out, from the device's forwarding database. Admins compare this against jnxMacAddressesLearnt to understand address-table churn, which helps distinguish normal aging behavior from unusual instability in the network. If jnxMacAddressesRemoved climbs in lockstep with jnxMacAddressesLearnt, it suggests devices are rapidly moving between ports or link-flapping rather than the table simply growing.
