BFD Down & BFD Link Failure Alarms

---on 3G Sites---MethodologyThe alarm analysis is based on alarm history taken from 24th to 28th of March. The analysis is done per RNC sorting out the count of BFD alarms in descending order.For internal use only# Nokia Siemens NetworksR 255 G 211 B 8R 255 G 175 B 0R 127 G 16 B 162R 163 G 166 B 173R 137 G 146 B 155R 175 G 0 B 51R 52 G 195 B 51R 0 G 0 B 0R 255 G 255 B 255Primary colours:Supporting colours:IntroductionFault reasonRemote node transmission error. (i.e. RNC=Local WBTS=Remote)

DescriptionThe alarm is raised if the BFD service is not available anymore on the BTS. In case only 1 BFD session is configured and activated, the alarm is raised if BFD on this session fails in either ingress or egress direction

InstructionsCheck if the far end has BFD switched on.Check cabling and network connections to the far end.
