LLDP Operating Notes
Neighbor Maximum. The neighbors table in the switch supports as many
neighbors as there are ports on the switch. The switch can support multiple
neighbors connected through a hub on a given port, but if the switch neighbor
maximum is reached, advertisements from additional neighbors on the same
or other ports will not be stored in the neighbors table unless some existing
neighbors time-out or are removed.
