DETAILED STEPS
Command Purpose
Step 1
enable
Example:
Router> enable
Enables the privileged EXEC mode.
Enter your password when prompted.
Step 2
configure terminal
Example:
Router# configure terminal
Enters the global configuration mode.
Step 3
ip sla operation number
Example:
Router(config)# ip sla 1101
Enables the IP SLA configuration.
operation-number—The IP SLA operation you want to
configure.
Step 4
ethernet y1731 delay DMM domain value
vlan vlan-id mpid value cos value
source mpid value
or
ethernet y1731 delay DMM domain value
vlan vlan-id inner-vlan inner vlan-id
mpid value cos value source mpid
value
Example:
Router(config-ip-sla)# ethernet y1731
delay DMM domain customer vlan 100
mpid 3101 cos 1 source mpid 4101
or
Router(config-ip-sla)# ethernet y1731
delay DMM domain customer vlan 100
inner-vlan 1101 mpid 3101 cos 1
source mpid 4101
Configures a two-way delay measurement.
Note Both single tagging and double tagging are
supported.
The following are the parameters:
• delay—Specifies the delay distribution parameter.
Note DMM is the only supported delay distribution
parameter.
• vlan—Specifies the VLAN.
• inner-vlan—The inner-vlan keyword and the inner
vlan-id argument specify the VLAN tag for
double-tagged packets.
• cos—Specifies the CoS. The value can be any
number between 0 and 7.
Note For double-tagged packets, the cos value
corresponds to the value specified for the
outer tag.
• mpid—Specifies the destination MPID.
• source—Specifies the source MPID.
Step 5
aggregate interval seconds
Example:
Router(config-sla-y1731-delay)#
aggregate interval 30
Configures the Y.1731 aggregation parameter, where
aggregate interval refers to the interval at which the
packets are sent.
seconds—Specifies the length of time, in seconds.
