Pix Firewall Issue

December 1, 2005

Hello Lists,
I am using Cisco pix 525. I have got problem with PIX firewall 525,
Interfaces ( inside, outside)
continuously “up-down” when I use with large traffic ( about 10Mb), but It
works fine when traffic less then 10 mb. Is any one has anyidea.

Any Suggestion are most welcome !!!

* I’ve seen this before…

Make sure all ur interfaces are set to the right speed and duplexity, 100 full duplex including switches and routers..
Also check buffers on the pix may have to increase. Them a litle.

* I would go out and get MRTG (google it). You can use it to monitor
the ram, cpu, traffic passed on the interface. Then you can see what
kind of corolation between the three. You may also want to upgrade to
the latest IOS (assuming you are not on it already).

* If you can afford it , get Solarwinds Suite , www.solarwinds.net.
There’s a utility within called Network Performance Monitor which would
help you on your traffic assessment.
If I am not wrong you can download an evalutation from their site.
