Description: This object is used to facilitate modification of IGMP Filter Editor Group in the CISCO-IGMP-FILTER-MIB module by multiple managers. In particular, it is useful when modifying the value of the cIgmpFilterEditor object.

The procedure for modifying the cIgmpFilterEditor object is as follows:

1. Retrieve the value of cIgmpFilterEditSpinLock and of object within cIgmpFilterEditor group.

2. Generate new values for 'writeable' objects in the cIgmpFilterEditor group except for cIgmpFilterEditSpinLock object.

3. Set the value of cIgmpFilterEditSpinLock to the retrieved value, and the value of objects in cIgmpFilterEditor to the new value. If the set fails for the cIgmpFilterEditSpinLock object, go back to step 1.

The cIgmpFilterApplyStatus and cIgmpFilterEditSpinLock should be read together by NMS to make sure that the result is associated with its configuration request.

To add/delete or modify a profile ( through cIgmpFilterEditor objects ) following procedure may be followed as an example.:

1. GET(cIgmpFilterEditSpinLock.0) and save in sValue. 2. SET(cIgmpFilterEditSpinLock.0 = sValue, cIgmpFilterEditProfileIndex.0 = validProfileNumber, cIgmpFilterEditStartAddress.0 = validStartAddress, cIgmpFilterEditEndAddress.0 = validEndAddress, cIgmpFilterEditOperation.0 = validOperation) 3. If the SET in step 2 is not successful go back to step 1. 4. If the SET in step 2 is successful, user should GET(cIgmpFilterEditSpinLock.0) and GET(cIgmpFilterApplyStatus.0) simultaneously.

5. The cIgmpFilterApplyStatus.0 reflects the outcome of step 2 only if cIgmpFilterEditSpinLock.0 = sValue + 1 or cIgmpFilterEditSpinLock.0 = 0 if sValue reaches value at which cIgmpFilterEditSpinLock wraps around.
