FEATURES AND BENEFITS
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 1and 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. |
