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:
- Specify a name for an SLA iterator profile—for example,
i1:
[edit protocols oam ethernet connectivity-fault-management performance-monitoring]
user@switch# edit sla-iterator-profiles i1
- (Optional) Configure the cycle time, which is the time
(in milliseconds) between back-to-back transmissions of SLA frames.
[edit protocols oam ethernet connectivity-fault-management performance-monitoring sla-iterator-profiles i1]
user@switch# set cycle-time cycle-time-value
- (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).
[edit protocols oam ethernet connectivity-fault-management performance-monitoring sla-iterator-profiles i1]
user@switch# set iteration-period iteration-period-value
- Configure the measurement type as two-way delay measurement.
[edit protocols oam ethernet connectivity-fault-management performance-monitoring sla-iterator-profiles i1]
user@switch# set measurement-type two-way-delay
- (Optional) Configure the calculation weight for delay.
[edit protocols oam ethernet connectivity-fault-management performance-monitoring sla-iterator-profiles i1]
user@switch# set calculation-weight delay delay-value
- (Optional) Configure the calculation weight for delay
variation.
[edit protocols oam ethernet connectivity-fault-management performance-monitoring sla-iterator-profiles i1]
user@switch# set calculation-weight delay-variation delay-variation-value
- Configure a remote MEP with the iterator profile.
