This object sets the maximum number of LLDP neighbors the device will store information for, system-wide, with the default determined by the performance profile of the specific hardware project. Admins on chassis with many ports and dense neighbor tables use this to cap memory consumption by LLDP, especially in large deployments where neighbor churn could otherwise exhaust resources. For example, setting this to 128 limits the switch to remembering at most 128 discovered LLDP neighbors across all ports before older entries are dropped.
