L2 transparency – Ethernet control protocols

../../_images/trsp-eth-ctrl.png

This task checks transparency for Ethernet control protocols:

  • LACP, Link Aggregation Control Protocol

  • EAPoL, Extensible Authorization Protocol over LAN

  • MVRP, Multiple VLAN Registration Protocol

Test procedure

For each protocol to be tested, five frames are generated and sent.

Fail criteria

When the expected outcome for a protocol is set to Pass, the test fails for that protocol if less than four frames are received.

When the expected outcome for a protocol is set to Drop, the test fails for that protocol if at least one frame is received.

Limitations

This test can only run on physical or VLAN interfaces (not bridges).

Regarding use of the Test Agent management interface for this test, see here.

Parameters

General

  • Sender: The sender Test Agent interface.

  • Receiver: The receiver Test Agent interface.

  • Wait for ready: Time to wait before starting this test step. The purpose of inserting a wait is to allow all Test Agents time to come online and acquire good time sync. Min: 1 min. Max: 24 hours. Default: “Don’t wait”, i.e. zero wait time.

Advanced

  • Expected outcome for LACP: Expected outcome for Link Aggregation Control Protocol. Default: Pass.

  • Expected outcome for EAPoL: Expected outcome for Extensible Authorization Protocol over LAN. Default: Pass.

  • Expected outcome for MVRP: Expected outcome for Multiple VLAN Registration Protocol. Default: Pass.

Result metrics

  • Pass/fail for each tested protocol
