Using Authorized IP Managers
Operating Notes
12-14
• Even if you need proxy server access enabled in order to use
other applications, you can still eliminate proxy service for web
access to the switch. To do so, add the IP address or DNS name
of the switch to the non-proxy, or "Exceptions" list in the web
browser interface you are using on the authorized station.
• If you don't need proxy server access at all on the authorized
station, then just disable the proxy server feature in the station's
web browser interface.
