ArubaOS-Switch – How to Enable Debugging for OSPF Neighbor Adjacency

MVP
MVP
Requirement:

Aruba 2930F Switch running firmware version WC.16.10.0003 



Solution:

While forming adjacency with each other, OSPF speaking neighbors go through several states before the routers are fully adjacent with each other. The state transitions can be displayed used OSPF debugging.



Configuration:

Rack2sw1# debug ip ospf event
Rack2sw1# debug destination session

Rack2sw1# show debug

 Debug Logging

  Source IP Selection: Outgoing Interface
  Origin identifier: Outgoing Interface IP
  Destination:
   Session

  Time-stamp: System-Uptime

  Enabled debug types:
   ip ospf event
