Irregular connectivity issue from a HTTP in DMZ through a PIX through Cisco 5509 to an application server
Posted on 2004-04-03
What kind of issue am I potentially dealing with here? Cisco wizzards please assist.
Here is the setup: DMZ with a webserver application configured to access an internal application server / database, routed through a PIX firewall and 5509 switch to access the application on a specific port. That port is open on the firewall. Firewall only allows 443 & 80 for the webserver.
This is the interesting part - accessibility of web apps via webserver works great at certain times of the day for an hour or so then it slows down to a halt, no timeouts of the webserver just takes a really long time and eventually opens up the page by fetching app server data as opposed to lightning fast in other times. Maybe some tasks kick off that take up much of the network bandwith at these particular times...
Is the bottleneck in the firewall or the switch? How can I isolate the issue (as a newby to Cisco)?
