Описание товара

Подробности

8-port Cisco ® Gigabit Ethernet Enhanced High-Speed WAN interface cards (EHWICs) can reduce your company's total cost of ownership (TCO) by integrating Gigabit Ethernet (GE) switch ports within Cisco 3900, 2900, and 1900 Series Integrated Services Routers (ISRs). These low-density Gigabit Ethernet switches offer small to medium-sized business (SMB) and enterprise branch-office customers a combination of switching and routing integrated into a single device

Feature

Benefit

4 or 8 10/100/1000BASE-TX ports

• The switches offer line-rate forwarding for Layer 2 traffic on each port.

Autosensing, autonegotiation, and Automatic Media-Dependant Interface Crossed Over (Auto-MDIX)

• Autosensing allows the switch to detect the speed of the attached device and automatically configure the port for 10-,100-, or 1000-Mbps operation.
• Autonegotiation allows the switch to automatically select half- or full-duplex transmission mode to optimize bandwidth on all the ports of the EHWIC.
• Auto-MDIX allows the switch to automatically detect cable type (straight-through vs. crossover) between an attached device and the switch port.

Integrated switching

• Integrated switching provides fewer points of management for remote and small branch offices.

Intrachassis stacking or cascading

• Grouping EHWIC switch modules together is called cascading. The EHWIC switch modules are capable of cascading on all Cisco Integrated Services Routers Generation 2 (ISR G2) platforms using the internal MGF.
• Cascading of multiple EHWIC switches over the MGF allows multiple EHWICs to behave as a single switch.
• Layer 2 switching of packets can be internal to each EHWIC switch or they can go through the MGF when multiple EHWIC switch modules in the system are acting as a unified switch. The router CPU is not involved in this operation.

IEEE 802.1P QoS (Traffic Prioritization)

• This feature supports QoS based on the IEEE 802.1P class of service (CoS) and port-based prioritization, allowing the switch to change the CoS settings of tagged packets on a per-port basis.
• Each port has eight QoS queues. Strict priority is enforced by default. The routers support SDWRR with configurable weight on each queue

802.1Q Trunking

• This feature provides an industry wide VLAN tagging standard, allowing for trunks also to be set up to third-party devices.

802.1D Spanning Tree Protocol

• This industry-standard link layer network protocol ensures a loop-free topology between Layer 2 devices regardless of vendor. IEEE 802.1D Spanning Tree Protocol is turned on by default.

Voice VLAN (VVLAN)

• VVLANs enable Cisco IP phones to place voice and data in their own separate VLANs. The EHWIC 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 Protocol to dynamically configure the Cisco IP phones

IEEE 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 Gigabit Ethernet technology with the appropriate PoE module and internal power supply can power Cisco IP phones and wireless access points. Support is provided for both IEEE 802.3af and enhanced PoE (ePoE).

IP Multicast management support

• The routers provide Internet Group Management Protocol (IGMP) snooping in hardware for management support.

SNMP management

• SNMP allows management of the MIB through a MIB browser.

Cisco IOS Software 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 enables 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 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.

Cisco VLAN Trunking Protocol (VTP; client, server, and transparent modes)

• Cisco VTP supports dynamic VLAN configuration across Cisco switches.

Cisco Configuration Professional -based configuration and device management

• This feature simplifies initial configuration of a switch through a web-based GUI, eliminating the need for more complex terminal emulation programs and CLI knowledge.
• Cisco Discovery Protocol reduces the cost of deployment by helping less-skilled personnel set up switches quickly and simply.

Status-indicator LEDs

• Two LEDs per port provide visual indication of the switch-port status and PoE status.
