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 buffered debugging
logging trap debugging
logging asdm debugging
logging mail warnings
logging from-address [email protected]
logging recipient-address [email protected] level errors
logging facility 22
logging host management 192.168.120.222.
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.
