POWERED DEVICE DISCOVERY
The Powered Device Discovery feature eases network-management burdens by automating the PoE feature. With Powered Device Discovery, the
Cisco Catalyst switch detects the presence of a powered device and supplies inline power automatically, eliminating the need to manually enable
ports for inline power. The Powered Device Discovery mechanism is intelligent enough to differentiate between an IP phone and a NIC, and does not
supply inline power to NICs or other devices not designed to use inline power. With this feature, network administrators can depend on automatic
and centralized control of inline power that is safe to deploy and maintain.
In addition to the standard Powered Device Discovery feature, the Cisco Catalyst 6500 Series PoE module also provides intelligent power
management such that it negotiates power requirements with Cisco powered devices using Cisco Discovery Protocol so that the switch supplies only
the required amount of power instead of the maximum possible for a specific device class, thereby optimizing the overall power consumption in the
system.
AUXILIARY VLAN
The unique Auxiliary VLAN feature offered by Cisco Systems
®
provides automatic VLAN configuration for IP phones. It places phones into their
own VLANs automatically, simplifying the task of overlaying a voice topology onto a data network. It allows network administrators to easily
segment phones into separate, logical networks, even though the data and voice infrastructure is physically the same—greatly simplifying the tasks of
managing a multiservice network and identifying and troubleshooting network problems.
The Auxiliary VLAN feature maintains VLAN assignments, even when phones are moved to new locations. When a user plugs a phone into the
switch, the switch provides the phone with the necessary VLAN information.
