The port in the local host where the SNMP Manager is bound to.
property LocalPort: Integer read get_LocalPort write set_LocalPort;
The LocalPort property must be set before the component is activated (Active is set to True). It instructs the component to bind to a specific port (or communication endpoint) in the local machine. The default port is 0 (random port). If you would like to receive traps, set LocalPort to 162 (standard trap port). However, it is recommended that the SNMPTrapMgr component be used for listening to traps, because SNMPMgr is limited to receiving SNMPv3 traps from a single agent only. SNMPTrapMgr does not have this limitation.
Note: on macOS and iOS, root permissions are required to set LocalPort to any value below 1024.
