IP Telephony and User-Mobility Support with Cisco Catalyst 6500 Series 10/100 and 10/100/1000 Ethernet Interface Modules

The Cisco Catalyst 6500 Series is a lead element in Cisco AVVID, providing numerous IP telephony and network security features for the enterprise.

The Cisco Catalyst 6500 Series delivered the industry's first Ethernet switching modules that provided PoE for converged data and voice traffic as well as other powered devices, such as wireless access points. Several Cisco Catalyst 6500 Series interface modules support PoE on each interface port, allowing customers to build campus multiservice data and voice networks for wiring closets with the following features:

• PoE: Provides power for Cisco Prestandard Inline Power and IEEE 802.3af standard PoE over standard Category 5 UTP cable up to 100 meters for such as IP phones and wireless access points

• Powered Device Discovery: Detects the presence of a powered device such as an IP phone and supplies inline power automatically

• Auxiliary VLAN using 802.1Q: Segments IP phones and data endpoints into separate, logical networks automatically

• Automatic quality of service (AutoQoS): Simplifies the task of configuring QoS mechanisms for IP telephony and more

• Cisco Identity Based Networking Services (IBNS): Enables greater security while simultaneously offering cost-effective management of changes throughout the organization

Cisco Catalyst Prestandard Inline Power and IEEE 802.3AF POE

Using existing Category 5 UTP installations, the PoE feature helps enable network administrators to control power distribution from a central location. Configuring Cisco Catalyst 6500 Series switches with uninterruptible-power-supply (UPS) systems helps ensure that building power outages will not affect network telephony connections, providing greater network availability.

Enabled by a daughter card for "pay-as-you-grow" flexibility, several Cisco Catalyst 6500 Series 10/100 and 10/100/1000 Ethernet interface modules support PoE. Some of these interface modules support the IEEE 802.3af standard as an additional upgrade option. The Cisco Catalyst PoE feature implementation passes the required domestic and international safety regulations and compliance measures.

All Cisco Catalyst 6500 Series 802.3af PoE modules support all three classes of powered devices, delivering a maximum of 15.4W per port as defined in the standard:

• Class 1: Up to 4W per port

• Class 2: Up to 7W per port

• Class 3: Up to 15.4W per port

All 802.3af PoE modules are capable of supporting up to 48 Class 3 devices per module (that is, 15.4W per port for 48 ports simultaneously). The maximum number of powered devices supported in a system for each class depends on the specific system configuration such as chassis type, supervisor engine, and power supply used. (Refer to Table 1.)

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.

Enhanced Operational Control for Enhanced Manageability

The Cisco Catalyst 6500 Series offers advanced network-management features to make it easy to manage fast-growing networks. This includes TDR supported on the new 48-port 10- and 100-Mbps and all the 48-port 10-, 100-, and 1000-Mbps Ethernet modules (part numbers WS-X6148A-RJ-45, WS-X6148A-45AF, WS-X6148A-GE-TX, WS-X6148A-GE-45AF, WS-X6148-GE-TX, WS-X6548-GE-TX, and WS-X6748-GE-TX, respectively). TDR tests cabling by sending a signal down the cable, reporting cable breaks, cable crimps, and improperly wired cable.

All Ethernet modules support extensive interface-level statistics, including four RMON groups: alarms, events, history, and statistics. Additional RMON groups (all nine groups) can be monitored using the integrated Cisco Catalyst 6500 Series Network analysis Module (NAM) or switch probes.

For in-depth network analysis, the Switched Port Analyzer (SPAN) feature helps network managers redirect traffic from each switched port to a specific VLAN, allowing them to add, move, and easily change group access to network resources from centralized locations using CiscoWorks network-management software.

Support for local, out-of-band management is delivered through a terminal or modem attached to the console or auxiliary interface of the supervisor engine. Remote in-band management is available with SNMP Versions 1, 2, and 3.

Cisco Catalyst 6500 Series PoE, Classic 10/100, and 10/100/1000 Interface Modules

Designed for deployment in wiring closets, high-density Cisco Catalyst 6500 Series Classic 10/100 and 10/100/1000 interface modules provide line-rate 10/100 Ethernet forwarding and gigabit bandwidth to the desktop capabilities. These interface modules feature PoE field-installable daughter cards for pay-as-you-grow investment protection and flexibility.

The 96 port 10/100 module (part number WS-X6196-21AF) is the industry's first 96-port 10/100 RJ-21 module with IEEE 802.3af support for all 96 ports, helping enable the Cisco Catalyst 6500 Series to deliver the industry's highest port densities ranging from 192 10/100 ports in a Cisco Catalyst 6503 chassis to 1152 10/100 ports in a Cisco Catalyst 6513 chassis for a very cost-effective solution in the wiring closet.

The WS-X6196-RJ-21 module doubles the port density in the system in the same footprint, using the stacked standard RJ-21 connectors. Port-density improvement can be achieved with no incremental investment in the cable infrastructure. With the 802.3af PoE daughter card, this module can support up to 96 Class 2 devices or 62 Class 3 devices per module (960W of PoE per module).

The 96-port 10/100 module (part number WS-X6148X2-RJ-45) is the industry's first 96-port 10/100 RJ-45 module that helps enable the Cisco Catalyst 6500 Series to deliver industry's highest port densities, ranging from 192 10/100 ports in a Cisco Catalyst 6503 chassis to 1152 10/100 ports in a Cisco Catalyst 6513 chassis for a very cost-effective solution in the wiring closet.

The 96-port 10/100 module (part number WS-X6148X2-RJ-45) doubles the port density in the system by allowing it to expand from 48 ports to 96 ports per slot with the addition of a splitter (included), typically mounted at the patch panel. The splitting also can occur at the wall jack, providing another option for doubling the port density of the switch without costly rewiring. This module also can function as a regular 48-port 10/100 module for maximum flexibility and scalability in the future. With the 802.3af PoE daughter card, this module can support up to 48 Class 3 devices per module when operating as a 48-port module, or up to 96 Class 2 devices per module when operating as a 96-port module (960W of PoE per module).

Using RJ-21 or RJ-45 connectors, the Cisco Catalyst 6500 Series classic 10/100 and 10/100/1000 modules are ready to be deployed in virtually all wiring-closet environments (Table 5) with the following operational advantages and characteristics:
