Initial Cisco IOS Software Release: 11.1

Example: Viewing and Clearing OSPF Neighbor State Transition Counters

The show ip ospf neighbor detail command is used to display the neighbor state transition counter.

 r4#  show ip ospf neighbor detail  Neighbor 2.2.2.2, interface address 172.16.2.1     In the area 0 via interface Ethernet1/0     Neighbor priority is 1, State is FULL,  6 state changes  DR is 172.16.2.2 BDR is 172.16.2.1     Options is 0x42     Dead timer due in 00:00:38     Neighbor is up for 01:06:06     Index 2/2, retransmission queue length 0, number of retransmission 1     First 0x0(0)/0x0(0) Next 0x0(0)/0x0(0)     Last retransmission scan length is 1, maximum is 1     Last retransmission scan time is 0 msec, maximum is 0 msec 

The clear ip ospf counters command will reset the state transition counter to 0.
