• High - Logs everything with maximum detail.
Example 4.14. Enabling OSPF Debug Log Events
In this example, the DebugHello and DebugRoute log events will be enabled for the OSPFProcess called
my_ospf_proc.
Command-Line Interface
gw-world:/> set OSPFProcess my_ospf_proc DebugHello=Low DebugRoute=High
Web Interface
1. Go to: Routing > OSPF > my_ospf_proc
2. Select the Debug tab
3. Now enter:
• Hello Packets: Low
• Routing Table Manipulation: High
4. Click OK
The OSPF CLI command
The CLI command ospf provides various options for examining the behaviour of OSPF in real-time
on a particular.
In order to see general OSPF activity on a CLI console, the -snoop option can be used:
gw-world:/> ospf -snoop=on
Usually, there is only one OSPFProcess defined for a firewall and there is therefore no need to
specify this explicitly in the command. The snooping processes is turned off with:
gw-world:/> ospf -snoop=off
A snapshot of the state of any of the different OSPF components can be displayed. For example, if
an OSPFInterface object has the name ospf_if1, details about this can be shown with the command:
gw-world:/> ospf -interface ospf_if1
A similar snapshot can be displayed for areas, neighbors, routes and LSAs.
OSPF interface operation can also be selectively halted and restarted. For example, to stop the
OSPFInterface called ospf_if1, the CLI command would be:
gw-world:/> ospf -ifacedown ospf_if1
Note: The high setting generates large amounts of data
When using the High setting, the firewall will log a large amount of information, even
when just connected to a small AS. Changing the advanced setting Log Send Per Sec
Limit may be required.
