test_0001()¶: disable IPFIX after first packets

class test_flowprobe.Flowprobe(methodName='runTest')¶

Bases: test_flowprobe.MethodHolder

Template verification, timer tests

test_0001()¶: timer less than template timeout

test_0002()¶: timer greater than template timeout

test_cflow_packet()¶: verify cflow packet fields

class test_flowprobe.MethodHolder(methodName='runTest')¶

Bases: framework.VppTestCase

Flow-per-packet plugin: test L2, IP4, IP6 reporting

create_stream(src_if=None, dst_if=None, packets=None, size=None, ip_ver='v4')¶

Create a packet stream to tickle the plugin

Parameters:	src_if (VppInterface) – Source interface for packet stream src_if – Dst interface for packet stream

debug_print = False¶

max_number_of_packets = 10¶

pkts = []¶

send_packets(src_if=None, dst_if=None)¶

classmethod setUpClass()¶: Perform standard class setup (defined by class method setUpClass in class VppTestCase) before running the test case, set test case related variables and configure VPP.

verify_cflow_data(decoder, capture, cflow)¶

verify_cflow_data_detail(decoder, capture, cflow, data_set={1: 'octets', 2: 'packets'}, ip_ver='v4')¶

verify_cflow_data_notimer(decoder, capture, cflows)¶

wait_for_cflow_packet(collector_intf, set_id=2, timeout=1, expected=True)¶

wait for CFLOW packet and verify its correctness

Parameters:	timeout – how long to wait
Returns:	tuple (packet, time spent waiting for packet)
