ASA 5520 Logging Help

[Eddie.brown1986]

Hello Folks,

I am running two ASA 5520 routers synched up with eachother. I had a massive connectivity issue this weekend that I am investigating. Now I have figured out how to get the live logging but I need to know how to get the old logs from my router.

Also I am looking to set up a log dump that could happen daily or perhaps weekly. Does anyone have any experience with this?

Thanks,

Eddie

Basically you need to setup logging server for firewall/router. If you want to store logs daily/weekly/monthly basis.

Devices logs will be genrated based on configuration level.

Level	System	Description
Emergency	0	System unusable messages
Alert	1	Immediate action required messages
Critical	2	Critical condition messages
Error	3	Error condition messages
Warning	4	Warning condition messages
Notification	5	Normal but significant messages
Information	6	Informational messages
Debugging	7	Debugging messages
