Example 6 with Mep

use of org.onosproject.incubator.net.l2monitoring.cfm.Mep in project onos by opennetworkinglab.

the class CfmMepManager method processDeviceRemoved.

 * This removes a MEP from the internal list of Meps, and updates remote meps list on other Meps.
 * Note: This does not call the device's CfmMepProgrammable, because there
 * would be no point as the device has already been removed from ONOS.
 * The configuration for this MEP may still be present on the actual device, and
 * any future config would have to be careful to wipe the Mep from the device
 * before applying a Mep again
 * @param removedDevice The device that has been removed
