Business Benefits
Customer Needs
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
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.

Per-port power consumption control allows you to specify a maximum power setting on an individual port.
Per-port PoE power sensing measures the actual power being drawn, enabling more intelligent control of
powered devices.
The Cisco PoE MIBs provide proactive visibility into power usage and allow you to set different power-level
thresholds.
Cisco Discovery Protocol Version 2 allows the NIMs to negotiate a more granular power setting than the
IEEE classification provides when connecting to Cisco devices such as IP phones or access points.
Multigigabit Fabric
The LAN switch NIMs have a gigabit connection to the MGF and transparently integrate into the system.
Connecting over the MGF enables the NIM to directly communicate with other MGF-enabled modules in the
system without involving the routers forwarding architecture (Figure 2). Throughput for direct module-to-module
traffic using the MGF will thereby not be limited by the platforms performance license levels. Layer 2 switching of
packets is thus done at the full Gigabit Ethernet line rate, either local to each LAN switch NIM or when transferring
the MGF with multiple MGF-enabled modules installed in the system; module-to-module MGF traffic throughput is
limited to 1 Gbps.
Figure 2.
Applications
Small and Medium-Sized Branch Offices
The Cisco Gigabit Ethernet LAN Switch NIMs in a small to medium-sized enterprise branch-office data deployment
scenario provide the flexibility of integrated routing and switching functions in one device. This scenario allows the
deployment of high-speed connections between individual network resources such as client desktops, servers, IP
phones, wireless access points, and video devices from a single device and at the same time allows for WAN
connectivity at Layer 3 through the router.
When deployed in a unified communications environment, the 4- or 8-port NIMs transparently interoperate with
analog or digital time-division multiplexing (TDM) voice gateway modules and Cisco Unified Communications
Manager Express IP Telephony, Cisco Survivable Remote Site Telephony (SRST), or Cisco Unified Border
Element solutions.

The 8-port NIM with optional PoE/PoE+ provides power and phone discovery for IP phones. In addition, the NIMs
support 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 4-port and 8-port NIMs to automatically detect the presence of an IP
phone; the 8-port NIM with PoE/PoE+ will supply power to it.
Feature
Benefit
4 or 8 10/100/1000BASE-TX ports
The switches offer line-rate forwarding for Layer 2 traffic on each port.
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.
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.
This feature supports QoS based on the IEEE 802.1P class of service (CoS) and portbased 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.
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.
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.
Support for 802.1X port-based authentication, single/multiple host mode, guest VLAN, MAC
Authentication Bypass (MAB), restricted VLAN, critical VLAN, and dynamic VLAN.
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 (PoE) and IEEE802.3at (POE+).
The routers provide Internet Group Management Protocol (IGMP) Snooping in hardware for
management support.
SNMP management
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 perswitch 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.
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.
