### Corrupted LSPs (ciiSysStatCorrLSPs)

Number of corrupted in-memory LSP frames detected:

> LSPs received from the wire with a bad checksum are silently dropped and not counted.

> LSPs received from the wire with parse errors are counted by ciiSysStatLSPErrors.

### Authentication Type Fails (ciiSysStatAuthTypeFails)

Number of frames with authentication type mismatches recognized by this Intermediate System (IS).

### Authentication Fails (ciiSysStatAuthFails)

Number of frames with authentication failures recognized by this IS.

### LSP Dbase Overloads (ciiSysStatLSPDbaseOloads)

Number of times the LSP database became overloaded.

### Manual Addr Dropped (ciiSysStatManAddrDropFromAreas)

Number of times a manual address has been dropped from the area.

### Exceed Max Attempts (ciiSysStatAttmptToExMaxSeqNums)

Number of times the IS has attempted to exceed the maximum sequence number.

### Sequence Number Skips (ciiSysStatSeqNumSkips)

Number of times a sequence number skip has occurred.

### Own LSP Purges (ciiSysStatOwnLSPPurges)

Number of times a brand new copy of the system's own LSP was received from some other node.

### ID Field Len Mismatches (ciiSysStatIDFieldLenMismatches)

Number of times a PDU with an ID field length value that is different than the one configured for the receiving system was received.

### Partition Changes (ciiSysStatPartChanges)

Number of partition changes that have taken place.

### SPF Runs (ciiSysStatSPFRuns)
