Network requirements

l          GigabitEthernet 2/0/1 and GigabitEthernet 2/0/2 of Switch A are each connected to a Cisco IP phone.
l          Configure voice VLAN 2 on Switch A. Enable CDP compatibility of LLDP on Switch A to allow the Cisco IP phones to automatically configure the voice VLAN, thus confining their voice traffic within the voice VLAN to be isolated from other types of traffic.

Prevent OpenDNS From Redirecting Google Searches


Fix for Firefox & IE Address Bar to Prevent OpenDNS From Redirecting Google Search pages

Like everyone else, I search the web from the browser address bar and have set Google as the default search engine in both Firefox and IE. I also use OpenDNS for DNS
Sounds like a perfect combination but a side effect of using OpenDNS is that you can no longer search Google from Firefox location bar or the address bar of Internet Explorer.

Stop OpenDNS From Redirecting Invalid URLs to their Search Pages

 We love OpenDNS but for one annoying feature where OpenDNS automatically redirects typos and invalid URLs to their own ad-filled search pages as in this screenshot.

Let me explain - if you type a non-existent web domain in your web browser (e.g. gmail.coms instead of gmail.com), you'll land up on OpenDNS search page and won't see the default "Address Not Found" error in your browser.
