Solution Overview

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.

AutoQoS

Network administrators can assign IP phones to separate IP subnets and VLANs to allow separate

QoS or security policies for IP phones. The administrative task of configuring QoS to establish

end-to-end traffic prioritization is greatly simplified by deploying AutoQoS, which configures QoS

on voice ports automatically.

Cisco IBNS

Cisco IBNS builds on and enhances the capabilities of industry-standard IEEE 802.1X 10 by

providing increased security and greater flexibility for enterprise wired or wireless network access.

Policies are associated with users, not physical ports. This provides users with greater mobility and

freedom, allowing security and service-level policies to travel with them throughout the enterprise.

As a result, network scalability is increased while simplifying network management through

centralized policy enforcement and dynamic provisioning. Centralized policy-based administration

decreases the time, complexity, and effort associated with port security techniques at the MAC

level. Cisco IBNS can help to quickly provision support for cross-functional or new project teams,

enable secure access for trusted partners and vendors, and facilitate secure conference-room

connectivity. For more information, refer to:
