Configuring an Iterator Profile
Copyright © 2012, Juniper Networks, Inc.
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 delay measurement
or loss measurement.
To create an iterator profile:
1. In configuration mode, go to the following hierarchy level:
[edit]
user@host# edit protocols oam ethernet connectivity-fault-management
performance-monitoring
2. Configure the SLA measurement monitoring iterator:
[edit protocols oam ethernet connectivity-fault-management performance-monitoring]
user@host# edit sla-iterator-profiles
3. Configure an iterator profile—for example, i1:
[edit protocols oam ethernet connectivity-fault-management performance-monitoring
sla-iterator-profiles]
user@host# set i1
4. (Optional) Configure the cycle time, which is the amount of time (in milliseconds)
between back-to-back transmission of SLA frames for one connection, with values
from 10 through 3,600,000. The default value is 1000 ms.
[edit protocols oam ethernet connectivity-fault-management performance-monitoring
sla-iterator-profiles i1]
user@host# set cycle-time cycle-time-value
5. (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), with values from 1 through 2000. The default value is 2000.
[edit protocols oam ethernet connectivity-fault-management performance-monitoring
sla-iterator-profiles i1]
user@host# set iteration-period iteration-period-value
6. Configure the measurement type as loss measurement, statistical frame-loss
measurment, or two-way delay measurement.
[edit protocols oam ethernet connectivity-fault-management performance-monitoring
sla-iterator-profiles i1]
user@host# set measurement-type (loss | statistical-frame-loss | two-way-delay)
7. (Optional) Configure the calculation weight for delay with values from 1 through
65,535. The default value is 1 (applicable only for two-way delay measurement).
[edit protocols oam ethernet connectivity-fault-management performance-monitoring
sla-iterator-profiles i1]
user@host# set calculation-weight delay delay-value
8. (Optional) Configure the calculation weight for delay variation with values from 1
through 65,535. The default value is 1 (applicable only for two-way delay
measurement).
