The show ip ospf stats command displays the following information:
Output field |
Description |
---|---|
NumBufAlloc |
Indicates the number of buffers allocated for OSPF. |
NumBufFree |
Indicates the number of buffers that are freed by the OSPF. |
NumBufAllocFail |
Indicates the number of times that OSPF failed to allocate buffers. |
NumBufFreeFail |
Indicates the number of times that OSPF failed to free buffers. |
NumTxPkt |
Indicates the number of packets transmitted by OSPF. |
NumRxPkt |
Indicates the number of packets received by OSPF. |
NumTxDropPkt |
Indicates the number of packets dropped before transmission by OSPF. |
NumRxDropPkt |
Indicates the number of packets dropped before reception by OSPF. |
NumRxBadPkt |
Indicates the number of packets received by OSPF that are bad. |
NumSpfRun |
Indicates the total number of SPF calculations performed by OSPF, which also includes the number of partial route table calculation for incremental updates. |
LastSpfRun |
Indicates the time (SysUpTime) since the last SPF calculated by OSPF. |
LsdbTblSize |
Indicates the number of entries in the link state database table. |
NumAllocBdDDP |
Indicates the number of times buffer descriptors were allocated for OSPF database description packets. |
NumFreeBdDDP |
Indicates the number of times buffer descriptors were freed after use as OSPF database description packets. |
NumBadLsReq |
Indicates the number of bad LSDB requests. |
NumSeqMismatch |
Indicates the number of mismatches for sequence numbers. |
NumOspfRoutes |
The count of OSPF routes. |
NumOspfAreas |
The count of all OSPF areas. |
NumOspfAdjacencies |
The count of adjacencies. |
NumOspfNbrs |
The count of OSPF neighbors. |
NumEnabledOspfAreas |
The count of OSPF areas with at least one enabled OSPF interface. This number counts against the scaling maximum when you add a new area. |
The following example displays the OSPF performance statistics.
