Alarm ID Severity level Alarm type0500 Critical Fault

III. Parameters

Name MeaningBoard type and slot No. or CPU No. Specifies the type of the board and the No. of

the slot or the CPU where the alarm occurs.

Impact on Systeml If the active SRU is removed, the active and standby SRUs are switched over when the

standby SRU is available. During switchover, the interworking with the LMT isdiSRUpted. This alarm is not reported in real time; however, it can be displayed in thealarm history record after the network element (NE) and the LMT can interwork.

l The NE is unavailable if the active SRU is removed when the standby SRU is unavailable.In addition, the alarm is not reported.

l If the active SPU is removed, the active and standby SPUs are switched over when thestandby SPU is available. If the standby SPU has all information of the active SPU beforethe switchover, the services of online users are not affected by the switchover; however,users cannot be activated on this pair of SPUs during the interval of the switchover. If thestandby SPU does not have all information of the active SPU before the switchover, some

21 ALM-0610 Interface-Probe Fault AlarmDescription

I. DescriptionIf the Eth-trunk interfaces work in active/standby mode, the active Eth-trunk interface sendsARP packets to probe the peer device. The alarm occurs if the number of probe failure timesreaches the configured threshold of link failure. In such a case, the active link is consideredfaulty, and the active and standby Eth-trunk interfaces are switched.After the active and standby Eth-trunk interfaces are switched, the fault alarm about the originalactive Eth-trunk interface persists if the new active link works normally. This is because theoriginal Eth-trunk interface used for sending ARP packets becomes the standby Eth-trunkinterface. The original active Eth-trunk interface reverts to the active state only if the new activelink is faulty and the Eth-trunk interfaces are switched again. The alarm is cleared when the peerdevice is probed with ARP packets.After this alarm occurs, manually clear this alarm after the fault of the original active link isrectified and it reverts to the normal state.II.

32 ALM-0638 IKE negotiating tunnelabnormal

DescriptionI. DescriptionThis alarm is generated when the GGSN considers the negotiated tunnel abnormal. Thenegotiated tunnel is abnormal if the IKE negotiation fails, if the renegotiation fails after SAexpiration, or if the detection of the IPSec tunnel through the KeepAlive packet fails. This alarmis cleared after the fault in the tunnel is rectified, the GGSN receives the IKE negotiation packetfrom the peer of the IPSec tunnel, and the IKE negotiation succeeds.II. Attribute

Alarm ID Severity Level Alarm Type638 Major Fault

III. Parameters

Name MeaningIKE peer name IKE peer name for identifying the device at

the peer end of the abnormal IPSec tunnel

Impact on SystemIf the alarm is generated, the communication link is broken between the GGSN and the peer ofthe IPSec tunnel corresponding to the IKE peer generating the alarm. If only one peer isconfigured for the IPSec tunnel, data transmission over the tunnel is interrupted. If multiple peersare configured, the GGSN uses another peer for data transmission.
