Configuring Ethernet CFM
Use the no form of each command to remove a configuration or to return to the default settings.
EXAMPLE
The following example shows how to set up notification for all defects:
Switch(config)# ethernet cfm alarm notification all
The following example shows how to set the time during which one or more defects must be present
before a fault alarm is issued to 5000 ms:
Switch(config)# ethernet cfm alarm delay 5000
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.
For more information about configuring IP SLAs, see Chapter 16, “Configuring Cisco IOS IP SLAs
Operations.”
This section includes the following topics:
• Manually Configuring an IP SLAs CFM Probe or Jitter Operation, page 17-19
