Re: Cisco switch into non-cisco switch, unknown initial lag

Thanks everyone, from the Wireshark capture I have determined that it was not the cameras nor the POE switch.

Rather, the webserver that serves the pages (which has, what basically equates to, embedded iframes to the camera streams) is timing out when nobody looks at it for awhile.

Apparently, I forgot how IIS running an ASP site likes to "fall asleep" if there is no site activity. It takes IIS a few seconds to start up the AppPool for that site if it hasn't served any content recently.

You can configure the app pool on IIS to not timeout and shutdown after 20 minutes (the default) if you want. Just make sure and set the configuration option to recycle it in the middle of the night. App pools running classic ASP are known to lock up if they don't recycle once in a while.
