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)
