This read-write value, from 1 to 50, caps the number of entries the LLDP-MIB's remTable will hold for this specific port, defaulting to 10. Admins tune it to bound memory use on ports connected to shared-media segments or hubs where many neighbors could otherwise be discovered. For example, an admin might raise this limit on a port connected to an unmanaged hub with numerous attached devices, so all of them can be tracked in the neighbor table instead of being capped at the default of 10.
