ASA syslog problem


My customer have a ASA 5550 in HA. It is the Internet Firewall.

In this moment the firewall have 50.000 connection. Customer review the log in the syslog server and noted wich not all syslog messages the firewall are notify to the syslog server.

The configuration is the follow:

logging enable

logging timestamp

logging standby

logging buffered debugging

logging trap debugging

logging asdm debugging

logging mail warnings

logging from-address

logging recipient-address level errors

logging facility 22

logging host management

All rules have the log keyword and debugging level.

I think, the firewall can't send the all messages because is busy with the conection. Someone have been this problem.

Thank you

Re: ASA syslog problem


For troubleshooting these few messages should be sufficient :for syslog U can remove buffered and trap debugging .

mail notifications stays as it is

logging host inside

logging timestamp

logging trap 5

logging on

Re: ASA syslog problem


Thank you for you comment. But the proble is the login messages not reflect all activities and conections through the firewall.
