byteblowerll.byteblower.TriggerBasic

class byteblowerll.byteblower.TriggerBasic(*args, **kwargs)

Receive-side packet processor which counts the incoming frames, matching a filter.

This trigger is always active and starts counting frames as soon as it is created. Counting continues until the trigger is destructed.

Note

The initial (empty) filter string accepts all incoming frames. See meth``FilterSet for filtering information.

A basic trigger object can be created via a ByteBlowerPort, using ByteBlowerPort.RxTriggerBasicAdd()

This trigger processes frames received on the ByteBlower interface where its parent ByteBlowerPort is located.

Example

Receive all frames on “trunk-1-2” of some server, matching UDP source or destination port 67.

port = bbServer.PortCreate('trunk-1-2')
trigger = port.RxTriggerBasicAdd()
bpf_filter = 'udp port 67'
trigger.FilterSet(bpf_filter)

__init__(*args, **kwargs)

Initialize self. See help(type(self)) for accurate signature.
