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:
