Configuring Ethernet CFM
Use the no form of each command to remove a configuration or to return to the default settings.
Configuring IP SLAs CFM Operation
You can manually configure an individual IP SLAs Ethernet ping or jitter echo operation or you can
configure IP SLAs 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.

feature module at this URL:

• For level level-id, enter a single level ID (0 to 7), a
range of level IDs separated by a hyphen, or a series of
level IDs separated by commas.
• For vlan vlan-id, enter the provider VLAN ID or IDs
as a VLAN-ID (1 to 4095), a range of VLAN-IDs
separated by a hyphen, or a series of VLAN IDs
separated by commas, or enter any for any VLAN.
Step 7

Verify the configuration.
Step 9
show ethernet cfm errors Enter this command after you enable CFM crosscheck to
display the results of the crosscheck operation.
Step 10
