LocalPort Property
The port in the local host where the class is bound to.
Syntax
snmptrapmgr.getLocalPort([callback]) snmptrapmgr.setLocalPort( localPort, [callback])
Default Value
162
Callback
The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).
The callback for the getLocalPort([callback]) method is defined as:
function(err, data){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'data' is the value returned by the method.
The callback for the setLocalPort([callback]) method is defined as:
function(err){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'err' has 2 properties which hold detailed information:
err.code err.message
Remarks
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 162 (standard trap port). If that port is busy, an error will be returned, unless the ForceLocalPort configuration setting is set to False, in which case a random port will be chosen.
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.
