Configure MEP Interfaces on Switches to Support Ethernet Frame Delay Measurements (CLI Procedure)

Ethernet frame delay measurement is a useful tool for providing performance statistics or supporting or challenging service-level agreements (SLAs). By default, Ethernet frame delay measurement uses software for timestamping and delay calculations. You can configure a switch to perform and display Ethernet frame delay measurements on Ethernet interfaces. The switches support software-assisted timestamping.

Before you can begin configuring MEP interfaces to support Ethernet frame delay measurements on switches, ensure that you have:

  • Configured Operation, Administration, and Maintenance (OAM) connectivity fault management (CFM) correctly

  • Enabled distributed periodic packet management (PPM) (distributed PPM is enabled by default)

To configure MEP interfaces on switches to support Ethernet frame delay measurements:

Enable the Ethernet frame delay measurement by issuing the monitor ethernet delay-measurement operational mode command. In this command, you must specify one measurement type (either one-way or two-way measurement), and you must specify either the unicast MAC address of the peer MEP or its numeric identifier.

Optionally, you can also specify the following parameters:

  • Number of frames to send to the peer MEP (count count)

  • Number of seconds to wait between sending frames (wait time)

  • Priority value of the delay measurement request frame (priority value)

  • Size of the data in the data TLV of the request packet (size value)

  • Suppression of the insertion of the session ID TLV in the request packet (no-session-id-tlv)
