One thing that left me a a little perplexed is that the manual says select the ports that will be enabled 1. Select the check boxes for the ports for which you want to enable the voice VLAN. 2. From the Voice VLAN Mode menu, select Enable. 3. Click the Apply button. The voice VLAN is now activated for the selected ports. in this case its easy enough to identify which ports as it is a new installation, but lets say its an existing infrastructure, and all the ports get enabled , would there be any adverse affects if the port doesnt have a phone connected?
