LocalPort Property

The port in the local host where the SNMP Manager is bound to.

Object Oriented Interface

public function getLocalPort();
public function setLocalPort($value);

Procedural Interface

ipworkssnmp_snmptcpmgr_get($res, 13 );
ipworkssnmp_snmptcpmgr_set($res, 13, $value );

Default Value



The LocalPort property must be set before the class is activated (Active is set to True). It instructs the class 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 class 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.

LocalPort cannot be changed once the class is Active. Any attempt to set the LocalPort property when the class is Active will generate an error.

Note: on macOS and iOS, root permissions are required to set LocalPort to any value below 1024.
