no efc last-update-within
 

• interval--number of units of time

Must be in active-measurement group configuration mode (config-engine-active), which requires privileged-level access.

Use once per active-measurement group.

Interval units in seconds

Use the efc last-update-within command to specify an interval of time in which IP addresses received from the optional EFC module must have sent or received data in order to be used as probe targets.

The efc last-update-within command is one of several commands which place restrictions on which endpoints obtained from the EFC module will be probed. See also:

• efc bytes minimum
• efc bytes top
• efc exclude-prefix
• efc source

You can use them together in the same active measurement group.

Use the no form of the command to remove the time restriction from the active-measurement group.
