Usage Information The show ip ospf process-id statistics command displays the error packet count received on each interface as:
  • The hello-timer remaining value for each interface
  • The wait-timer remaining value for each interface
  • The grace-timer remaining value for each interface
  • The packet count received and transmitted for each neighbor
  • Dead timer remaining value for each neighbor
  • Transmit timer remaining value for each neighbor
  • The LSU Q length and its highest mark for each neighbor
