Use statistics to help you monitor Open Shortest Path First (OSPF) performance.

Syntax

show ip ospf stats
show ip ospf stats [vrf WORD<1-16>] [vrfids WORD<0-512>]
show ip ospf stats vrf WORD<1-16>
show ip ospf stats vrfids WORD<0-512>

Command Parameters

vrf WORD<1-16>: Specifies a VRF instance by VRF name.
vrfids WORD<0-512>: Specifies a VRF or range of VRFs by ID.

Default

None

Command Mode

User EXEC

Command Output

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.
