5. Troubleshooting5-10 May 2003 9000-A2-GB33-20LMI Down, frame relaylink 2 The Local ManagementInterface is down for thespecified frame relay link.For the network interface: If LMI was never up, verify thatthe LMI Protocol settingreflects the LMI type beingused. If LMI was never up:– Verify that the proper timeslots have been configured.– Verify that the LMI Protocolsetting reflects the LMI typebeing used. Verify that Frame RelayPerformance Statistics showLMI frames being transmitted.If all of the above have beenverified and the physical link is notin Alarm, contact your networkprovider.For user data port: Check that the DTE cable issecurely attached at both ends. Verify that Transmit ClockSource and Invert TransmitClock options are properlyconfigured. Verify that Frame RelayPerformance Statistics showLMI frames being received. Ifno frames are being received:– Check the attached device.– Verify that the LMI Protocolsetting reflects the LMI typebeing used.LOF at Network 1LOF at T3 User,Port-1 (9520-ILM)Loss Of Frame occurred onthe specified interface. AnOut Of Frame (OOF)condition has persisted for2.5 seconds.The condition is cleared whenthere are no OOF errors over a10-second period. If the problempersists, contact your networkprovider.Table 5-1. Alarm Conditions (4 of 8)Alarm Condition What It Indicates What To Do1 nnnn indicates a DLCI number of 16 through 1007.2 frame relay link is one of the following:– Net1-FR1. The frame relay link specified for the network interface, Network 1.– Port-n. The frame relay link associated with a user data port.– ISDN Link Name on a non-network ISDN DBM interface.3 Does not apply to a TS Access Management Link DLCI. PreviousNext |
