Product Overview
The 4-port Cisco® Gigabit Ethernet LAN Switch Network Interface Modules (NIMs) can reduce your company's total cost of ownership (TCO) by integrating Gigabit Ethernet switch ports within Cisco 4000 Series Integrated Services Routers (ISRs). These low-density Gigabit Ethernet switches offer small to medium-sized businesses and enterprise branch offices a combination of switching and routing integrated into a single device.
Integration of these switches with Cisco IOS-XE Software allows network administrators to manage a single device using Cisco management tools or the router command-line interface (CLI) for LAN and WAN management needs. This approach reduces network complexity, lowers maintenance contract costs, and lessens staff training needs. It also simplifies software qualification efforts and delivers a consistent user experience at branch offices. Additionally, these low-density Gigabit Ethernet switching modules enable Cisco's industry-leading power initiatives, power monitoring, which enhances the ability of the branch office to scale to higher performance requirements and still meet environmental initiatives for IT teams to operate a power-efficient network.
The 4-port Gigabit Ethernet LAN Switch NIMs provide line-rate Layer 2 switching across onboard Gigabit Ethernet ports. The 4-port NIM has 4 10/100/1000 switched Gigabit Ethernet ports. The NIMs furthermore enable direct module-to-module communication through the use of the multigigabit fabric (MGF).
The new features for the Gigabit Ethernet LAN Switch NIMs include four quality-of-service (QoS) queues per port, Shaped Deficit Weighted Round Robin (SDWRR), dynamic secure port, intra chassis cascading.
Business Benefits
Customer Needs | How Addressed by Cisco NIMs |
Total Cost of Ownership | |
● Scaled network infrastructure across multiple sites ● Decreased costs of operating multiple devices at the branch office ● Optimized IT resources | ● An integrated switch solution lowers operating costs, simplifies troubleshooting, and enables businesses to scale. ● One vendor also means one support center, eliminating blaming among vendors, thereby reducing troubleshooting time. ● Cisco Smart Net Total Care™ support covers both ISRs and Cisco EtherSwitch® devices. |
Ease of Management | |
● Reduced network complexity and simplified branch-office router management ● Single administration and configuration of LAN and WAN policies | ● Integrated switches allow simplified configuration and management. ● CiscoWorks LAN Management Solution (LMS), Remote Monitoring (RMON1 and RMON2), and standards-based MIBs support provides configuration as well as detailed reporting and troubleshooting capabilities. ● Simple Network Management Protocol Versions 1, 2, and 3 (SNMPv1, v2, and v3) offer comprehensive in-band management, and a CLI management console provides detailed out-of-band management. ● The management interface uses standard SNMP or Secure Sockets Layer (SSL) to integrate Cisco and third-party management systems. |
Green IT | |
● Single power supply for Cisco EtherSwitch device and router | ● These switches provide two to eight times lower power consumption than standalone switches. ● Because no additional rack space or power supply is needed, there is less to rack, stack, and cool. |
Architecture, Features, and Benefits
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-Dependent 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 NIM. ● 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 LAN switch NIMs together is called cascading. The NIMs are capable of cascading on all Cisco 4000 Series ISRs using the internal MGF. ● Cascading of multiple LAN switch NIMs over the MGF allows multiple NIMs to behave as a single switch. ● Layer 2 switching of packets can be internal to each LAN switch NIM, or they can go through the MGF when multiple LAN switch NIMs 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 four 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 helps ensure a loop-free topology between Layer 2 devices regardless of vendor. IEEE 802.1D Spanning Tree Protocol is turned off by default. |
Voice VLAN (VVLAN) | ● VVLANs enable Cisco IP phones to place voice and data in their own separate VLANs. The NIM 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 | ● Support for 802.1X port-based authentication, single/multiple host mode, guest VLAN, MAC Authentication Bypass (MAB), restricted VLAN, critical VLAN, and dynamic VLAN. |
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 management 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 | ● 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. |
