Configuring IP SLA CFM Operation
You can manually configure an individual IP SLA ethernet ping, or jitter echo operation, or you can
configure IP SLA ethernet operation with endpoint discovery. You can also configure multiple operation
scheduling. For accurate one-way delay statistics, the clocks on the endpoint switches must be
synchronized. You can configure the endpoint switches with Network Time Protocol (NTP) so that the
switches are synchronized to the same clock source.
For more information about configuring IP SLA ethernet operations, see the IP SLAs Configuration
Guide, Cisco IOS Release 15.0S. For detailed information about commands for IP SLAs, see the Cisco
IOS IP SLAs Command Reference.
Note The Cisco ASR 901 does not necessarily support all of the commands listed in the Cisco IOS IP SLA
documentation.
This section includes these procedures:
• Manually Configuring an IP SLA CFM Probe or Jitter Operation, page 10-16
• Configuring an IP SLA Operation with Endpoint Discovery, page 10-18
Manually Configuring an IP SLA CFM Probe or Jitter Operation
To manually configure an IP SLA ethernet echo (ping) or jitter operation, complete the following steps:
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
ip sla operation-number Create an IP SLA operation, and enter IP SLA
configuration mode.
Step 3
ethernet echo mpid identifier domain domain-name
vlan vlan-id
or
ethernet jitter mpid identifier domain domain-name
vlan vlan-id [interval interpacket-interval]
[num-frames number-of frames transmitted]
Configure the IP SLA operation as an echo (ping) or jitter
operation, and enter IP SLA ethernet echo configuration
mode.
• Enter echo for a ping operation or jitter for a jitter
operation.
• For mpid identifier, enter a maintenance endpoint
identifier. The identifier must be unique for each
VLAN (service instance). The range is 1 to 8191.
• For domain domain-name, enter the CFM domain
name.
• For vlan vlan-id, the VLAN range is from 1 to 4095.
• (Optional—for jitter only) Enter the interval between
sending of jitter packets.
• (Optional—for jitter only) Enter the num-frames and
the number of frames to be sent.
