what if  i choose another facilty  ?


if i put one interface in tap mode  can i  forward the log to syslog server

Yes you can. Make sure the security policy that you will create for the tap mode apply the syslog profile in the security policy.

Hi Sib


are you seeing some logs or none on the syslog server ?

the facility is merely a 'view' option in syslog, you should be able to toggle your syslog server to that view to make sure the logs are being received


to verify logs are being forwarded properly, please take a look at 

> debug log-receiver statistics

at the bottom you will see 

External Forwarding stats:
      Type  Enqueue Count     Send Count     Drop Count    Queue Depth     Send Rate(last 1min)
    syslog              0              0              0              0                        0

which can help determine if syslog is being sent out properly or not

What is the differnces between facility 7 and facilty 6 .

choosing facilty 7 will increase the visibilty of the logs , (mean wil it include all logs )

As I understand syslog facility is used on the syslog server to decide which log goes into which file. Facility will not help to increase or decrease the level of logging on the firewall.


As per RFC: following are the facility codes defined:



Facility code Keyword Description
0 kern kernel messages
1 user user-level messages
2 mail mail system
3 daemon system daemons
4 auth security/authorization messages
5 syslog messages generated internally by syslogd
6 lpr line printer subsystem
7 news network news subsystem
8 uucp UUCP subsystem
9   clock daemon
10 authpriv security/authorization messages
11 ftp FTP daemon
12 - NTP subsystem
13 - log audit
14 - log alert
15 cron scheduling daemon
16 local0 local use 0 (local0)
17 local1 local use 1 (local1)
18 local2 local use 2 (local2)
19 local3 local use 3 (local3)
20 local4 local use 4 (local4)
21 local5 local use 5 (local5)
22 local6 local use 6 (local6)
23 local7 local use 7 (local7)


Whereas the severity under the Log forwarding profile helps to decide what kind of logs you want to send to the syslog server.


You can choose to send different severity logs to the same syslog server with different facility values, so that they can be handled separately by the server. I hope this helps.
