Configure an Iterator Profile on a Switch (CLI Procedure)

date_range 28-Nov-23

Ethernet frame delay measurement provides fine control to operators for triggering delay measurement on a given service and can be used to monitor service-level agreements (SLAs). You can create an iterator profile with its parameters to periodically transmit SLA measurement packets in the form of ITU-Y.1731-compliant frames for two-way delay measurement.

To create an iterator profile:

  1. Specify a name for an SLA iterator profile—for example, i1:
    content_copy zoom_out_map
    [edit protocols oam ethernet connectivity-fault-management performance-monitoring]
user@switch# edit sla-iterator-profiles i1
  2. (Optional) Configure the cycle time, which is the time (in milliseconds) between back-to-back transmissions of SLA frames.
    content_copy zoom_out_map
    [edit protocols oam ethernet connectivity-fault-management performance-monitoring sla-iterator-profiles i1]
user@switch# set cycle-time cycle-time-value
  3. (Optional) Configure the iteration period, which indicates the maximum number of cycles per iteration (the number of connections registered to an iterator cannot exceed this value).
    content_copy zoom_out_map
    [edit protocols oam ethernet connectivity-fault-management performance-monitoring sla-iterator-profiles i1]
user@switch# set iteration-period iteration-period-value
  4. Configure the measurement type as two-way delay measurement.
    content_copy zoom_out_map
    [edit protocols oam ethernet connectivity-fault-management performance-monitoring sla-iterator-profiles i1]
user@switch# set measurement-type two-way-delay
  5. (Optional) Configure the calculation weight for delay.
    content_copy zoom_out_map
    [edit protocols oam ethernet connectivity-fault-management performance-monitoring sla-iterator-profiles i1]
user@switch# set calculation-weight delay delay-value
  6. (Optional) Configure the calculation weight for delay variation.
    content_copy zoom_out_map
    [edit protocols oam ethernet connectivity-fault-management performance-monitoring sla-iterator-profiles i1]
user@switch# set calculation-weight delay-variation delay-variation-value
  7. Configure a remote MEP with the iterator profile.
    content_copy zoom_out_map
    [edit protocols oam ethernet connectivity-fault-management maintenance-domain md-name maintenance-association ma-name mep mep-id remote-mep remote-mep-id]
user@switch# set sla-iterator-profiles i1
