Engineering Guidelines

Shutting down a port is a good way to restrict access, but it will also affect the operation of the
phone, or any other device, attached to this port.
The MiVoice IP Phones will obtain the VLAN information via CDP, if available. In this case, the
phone will not need to use the double fetch method via DHCP; the first DHCP request will be
on the voice VLAN with tagged frames.

CAUTION: Shutting down a port could be considered a form of denial of service.
Simply plugging a rogue PC into a number of network ports could disable
access to legitimate users. Be careful to select the appropriate settings.
