1.1 Impact on System
IPPM is unacted, that will lead that the capability delectability of the IPPATH is out of action
1.2 The solution Clears alarm IPPM Activation Failure
1.2.1 Display on Node B and RNC to make sure about Differentiated Services Code Point
1.2.2 Remove IPPATH on Node B

After LST IPPATH see Node B ON Differentiated Services Code Point = 63.Now the value of DSCP is 63 so we need to change the DSCP from 63 to 46.
This is Node B don’t have alarm IPPM Activation Failure after LST IPPATH, so see Node B ON Differentiated Services Code Point = 46
