How to Configure ITU-T Y.1731 Performance Monitoring
Step 5
ethernet y1731 loss SLM domain
domain-name
{evc
evc-id
| vlan
vlan-id
} {mpid
target-mp-id
|
mac-address
target-address
} cos
cos
{source {mpid
source-mp-id
| mac-address
source-address
}}
Example:
Router(config-ip-sla)# ethernet y1731 loss SLM
domain xxx evc yyy mpid 101 cos 4 source mpid 100
Configures a single-ended synthetic loss
measurement and enters IP SLA Y.1731 loss
configuration mode.
• SLM—Specifies that the frames sent are
Synthetic Loss Measurement (SLM) frames.
• domain domain-name—Specifies the name of
the Ethernet Connectivity Fault Management
(CFM) maintenance domain.
• evc evc-id—Specifies the EVC identification
name.
• vlan vlan-id—Specifies the VLAN identification
number. The range is from 1 to 4096.
• mpid target-mp-id—Specifies the maintenance
endpoint identification numbers of the MEP at
the destination. The range is from 1 to 8191.
• mac-address target-address—Specifies the
MAC address of the MEP at the destination.
• cos cos—Specifies, for this MEP, the class of
service (CoS) that will be sent in the Ethernet
message. The range is from 0 to 7.
• source—Specifies the source MP ID or MAC
address.
• mpid source-mp-id—Specifies the maintenance
endpoint identification numbers of the MEP
being configured. The range is from 1 to 8191.
• mac-address source-address—Specifies the
MAC address of the MEP being configured.
Step 6
aggregate interval
seconds
Example:
Router(config-sla-y1731-loss)# aggregate interval
900
(Optional) Configures the length of time during
which the performance measurements are conducted
and the results stored.
• seconds—Specifies the length of time in seconds.
The range is from 1 to 65535. The default is 900.
Step 7
availability algorithm {sliding-window |
static-window}
Example:
Router(config-sla-y1731-loss)# availability
algorithm static-window
(Optional) Specifies availability algorithm used.
• sliding-window—Specifies a sliding-window
control algorithm.
• static-window—Specifies static-window control
algorithm.
Step 8
frame consecutive
value
Example:
Router(config-sla-y1731-loss)# frame consecutive 10
(Optional) Specifies number of consecutive
measurements to be used to determine availability or
unavailability status.
• value—Specifies the number of consecutive
measurements. The range is from 1 to 10. The
default is 10.
