Product Overview

The 4- and 9-port Cisco^® EtherSwitch^® 10/100 high-speed WAN interface cards (HWICs) supported onthe Cisco 1800 (modular)/1941, Cisco 2800/2900, and Cisco 3800/3900 series integrated services routers offer small-to-large-size businesses and enterprise branch office customers the option to integrate switching and routing in one device. This combination offers ease of configuration, deployment, and management while using the powerful characteristics of Cisco routing and Cisco Catalyst^® switching features.

The modular 4- and 9-port Cisco EtherSwitch HWICs provide line-rate Layer 2 switching across Ethernet ports using Cisco IOS^® Catalyst Software. The 4-port Cisco EtherSwitch HWIC has four 10/100 switched Ethernet ports, with options for inline power support on all four ports. The 9-port Cisco EtherSwitch HWIC has nine 10/100 switched Ethernet ports, with options for inline power support on 8 of the 9 ports. The ninth port does not support inline power but can be used as a regular switch port for trunking and other normal data applications. Features such as port autosensing, quality of service (QoS), VLAN support from 802.1P and 802.1Q standards, and 802.1D spanning tree protocols are standard on the Cisco EtherSwitch HWIC. The Cisco EtherSwitch HWICs are available in standard 4- or 9-port 10/100BASE-TX switch HWIC and Power-over-Ethernet (PoE) configurations. The PoE configurations consist of a 4- or 9-port 10/100BASE-TX switch and a 4- or 8-port inline power module daughter card. The power module daughter card houses a power controller for detecting, classifying, and enabling power on 802.3af-compliant powered devices attached to the HWICs. The inline powered version of the Cisco EtherSwitch HWIC can power Cisco IP phones, Cisco wireless access points, or any other IEEE 802.3af-compliant device. The optional inline power support on the 4- and 9-port HWICs on the Cisco 2800/2900 and Cisco 3800/3900 series of integrated services routers requires the use of a field-replaceable inline power supply. (Refer to Figure 1.)

Applications

Small Branch Data Only

Figure 2 shows an example of a deployment for a small-to-large enterprise branch office.

Figure 2. Typical Data-Only Deployment for a Small-to-Large Enterprise Branch Office

A Cisco EtherSwitch HWIC in an enterprise branch data deployment scenario provides the flexibility of integrated routing and switching functions in one unit for low port densities. This deployment provides high-speed connections between individual desktops, servers, and other network resources in a single unit for Layer 2 and allows WAN connection at Layer 3 through the router.

Figure 3 shows an example of a typical converged deployment for a small-to-large enterprise branch office with IPphones.

Figure 3. Typical Converged Deployment for a Small-to-Large Enterprise Branch Office with IP Phones

The 4- or 9-port Cisco EtherSwitch HWICs when combined with analog or digital voice modules for the Cisco Integrated Services Routers provide a small-to-large enterprise branch office infrastructure for IP telephony deployments. This solution can be combined with Cisco CallManager Express IP Telephony or the Cisco IOS Software Survivable Remote Site Telephony (SRST) solution. SRST runs on the local branch office router, allowing it to automatically detect a failure in the network, and initiates a process to intelligently autoconfigure the router to provide call-processing backup redundancy for the IP phones in that office. In the case of a Cisco CallManager Express deployment, call-processing features are offered on the branch router without a centralized call manager.

The Cisco EtherSwitch HWIC with the optional internal chassis provides IP phone power and phone discovery for IP phones. In addition, the Cisco EtherSwitch HWIC supports separate VLAN configuration for IP phones. The auxiliary VLAN feature allows network administrators to segment phones into separate logical networks, even though the data and voice infrastructures are physically the same. The phone discovery feature allows the Cisco 4- and 9-port EtherSwitch HWICs (product numbers HWIC-4ESW-POE or HWIC-D-9ESW-POE) to automatically detect the presence of an IP phone and supply inline power.

Features and Benefits

Table 4 gives the architecture, features, and benefits of the Cisco 4- and 9-port HWICs.

Table 4. Architecture, Features, and Benefits of 4- and 9-Port Cisco EtherSwitch HWICs

Feature	Benefit
4 or 9 10BASE-T/100BASE-TX Ports	● These ports deliver up to 200 Mbps of aggregate bandwidth (full duplex) for forwarding Layer 2 traffic on each port.
Autosensing, Autonegotiation, and Auto-MDIX (Automatic Media-Dependant Interface Crossed Over)	● The Autosensing feature allows the switch to detect the speed of the attached device and automatically configure the port for 10- or 100-Mbps operation. ● The Autonegotiation feature allows the switch to automatically select half- or full-duplex transmission mode to optimize bandwidth on all the ports of the HWIC ● The Auto-MDIX feature allows the switch to automatically detect cable type (straight through vs. crossover) between the attached Ethernet device and switch line pairs.
Integrated Switching	● Integrated switching provides fewer points of management for remote and small branch offices.
802.1P QoS (Traffic Prioritization)	● This feature provides support for QoS based on the IEEE class of service (CoS) and port-based prioritization, allowing the switch to change the CoS settings of tagged packets on a per-port basis.
802.1Q Trunking	● This feature allows the setup of separate VLANs with tagged and untagged framing; trunking is used to save ports when creating a link between two devices implementing VLANs; VLANs allow segmentation of the LAN.
802.1D Spanning Tree Protocol	● This Layer 2 link-management protocol provides path redundancy while preventing undesirable loops in the network; it simplifies network configuration and improves fault tolerance.
Voice VLAN (VVLAN)	● VVLANs help enable Cisco IP phones to place voice and data in their own separate VLANs. The HWIC switch port is manually configured as a trunk port to support voice and data VLANs on the same port. The switch then uses Cisco Discovery to dynamically configure the Cisco IP phones.
802.1x Authentication	● This client-server-based access control and authentication protocol restricts unauthorized devices from connecting to a LAN through publicly accessible ports.
PoE (Option)	● Cisco EtherSwitch technology with the appropriate inline power module and internal power supply can power Cisco IP phones and wireless access points. Support is provided for both IEEE 802.3af PoE and Cisco prestandard inline powered devices. The ninth port of the 9-port HWIC (part number HWIC-D-9ESW-POE) cannot be used for PoE applications. The PoE option is not available on the Cisco 1841 router.
Multicast Management Support	● This feature offers Internet Group Management Protocol (IGMP) snooping in hardware for management support.
Simple Network Management Protocol (SNMP) Management	● SNMP allows management of the MIB through a MIB browser.
Cisco IOS Software Command-Line Interface (CLI)	● This feature provides configuration through the Cisco IOS Software CLI and provides a common user interface for all the router functions.
CiscoWorks Support	● CiscoWorks network management software helps enable manageability on a per-port and per-switch basis, providing a common management interface for Cisco routers, switches, and hubs. ● SNMPv1, v2, and v3 (noncryptographic) and Telnet interface support delivers comprehensive in-band management, and a CLI management console provides detailed out-of-band management. ● Cisco Discovery Protocol Versions 1 and 2 help enable a CiscoWorks network management station to automatically discover the switch in a network topology. ● Support is provided by the CiscoWorks LAN Management Solution.
Cisco Discovery Protocol Versions 1 and 2	● This protocol enables a CiscoWorks network management station to automatically discover the switch in a network topology.
VLAN Trunking Protocols (Client, Server, and Transparent Modes)	● The Cisco Virtual Lan Trunking Protocol (VTP) supports dynamic VLAN configuration across Cisco switches.
Cisco Secure Router and Device Manager (SDM)-Based Configuration and Device Management	● This feature simplifies initial configuration of a switch through a Web browser, eliminating the need for more complex terminal emulation programs and CLI knowledge. ● Cisco SDM reduces the cost of deployment by helping less-skilled personnel set up switches quickly and simply.
Status LEDs	● Two LEDs per port provide convenient visual indication of the switch port and inline power status.
