show ip ospf statistics

Display OSPF statistics.

Syntax
show ip ospf [process-id | vrf vrf-name] statistics global | [interface name {neighbor router-id}]
Parameters
process-id
Enter the OSPF Process ID to show a specific process. If no Process ID is entered, command applies only to the first OSPF process.
vrf vrf-name
Enter the keyword vrf followed by the name of the VRF to display statistics corresponding to the OSPF process that is tied to a specific VRF.
global
Enter the keyword global to display the packet counts received on all running OSPF interfaces and packet counts OSPF neighbors receive and transmit.
interface name
(OPTIONAL) Enter the keyword interface then one of the following interface keywords and slot/port or number information:
  • For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port[/subport] information.
  • For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information.
  • For a port channel interface, enter the keywords port-channel then a number.
  • For a VLAN interface, enter the keyword vlan then a number from 1 to 4094.
neighbor router-id
(OPTIONAL) Enter the keyword neighbor then the neighbor’s router-id in dotted decimal format (A.B.C.D.).
Defaults
None

The following describes the error definitions for the show ip ospf statistics process-id global command.

Error Type
Description
Intf_Down
Received packets on an interface that is either down or OSPF is not enabled.
Non-Dr
Received packets with a destination address of ALL_DRS even though SELF is not a designated router.
Self-Org
Receive the self originated packet.
Wrong_Len
The received packet length is different to what was indicated in the OSPF header.
Invld-Nbr
LSA, LSR, LSU, and DDB are received from a peer which is not a neighbor peer.
Nbr-State
LSA, LSR, and LSU are received from a neighbor with stats less than the loading state.
Auth-Error
Simple authentication error.
MD5-Error
MD5 error
Cksum-Err
Checksum Error
Version
Version mismatch
AreaMismatch

No-Buffer
Buffer allocation failure.
Seq-no
A sequence no errors occurred during the database exchange process.
Socket
Socket Read/Write operation error.
Q-overflow
