On the Barracuda NextGen Firewall F-Series, you can activate debugging for OSPF. This can be useful when a higher verbosity for OSPF logging is required.
In the directory that contains the OSPF configuration files, create a new file named
cd /opt/phion/config/active/servers/<servername>/services/ospf/ vi ospf.debug
ospf.debugfile, enter the cipher 9 as the initial and only value. Then save the file.
The following entry is generated in the OSPF log file after the file has been saved, indicating a changed log level:
INFO Debug file changed: reloading (9 -> verb: 9, exact: -1)
