Chapter Configuring Multi-Gigabit Fabric Communication
Supported Slots, Modules, and Interface Cards
The following modules and interface cards support communication through the MGF:
• Wireless LAN Module in the Cisco 1941W ISR, page 212
• Cisco Etherswitch Service Modules, page 212
Cisco 3900 Series, Cisco 2900 Series, and Cisco 1900 Series Integrated Services Routers support legacy
interface cards and modules. Some modules will require an adapter. See your router’s hardware
installation guide at Cisco.com for adapter installation information.
See the routers’s Product page at Cisco.com for a complete list of supported new and legacy modules.
Wireless LAN Module in the Cisco 1941W ISR
When configured as an autonomous access point, the wireless LAN (WLAN) device serves as the
connection point between wireless and wired networks or as the center point of a stand-alone wireless
network. In large installations, wireless users within radio range of a device can roam throughout a
facility while maintaining seamless and uninterrupted access to the network.
Cisco 1941W supports ISM-to-EHWIC communication with an integrated switch communicating
through the MGF. In this scenario traffic goes from the WLAN, through the Multi-Gigabit Fabric’s CPU
port, and out through a port on the front panel.
Cisco Etherswitch Service Modules
The following Cisco EtherSwitch service modules provide Cisco modular access routers the ability to
stack Cisco EtherSwitch service modules as Layer 2 switches using Cisco StackWise technology.
• NME-16ES-1G
• NME-16ES-1G-P
• NME-X-23ES-1G
• NME-X-23ES-1G-P
• NME-XD-48ES-2S-P
• NME-XD-24ES-1S-P
The Cisco EtherSwitch service modules are supported by either the IP base image (formerly known as
standard multilayer image [SMI]) or the IP services image (formerly known as the enhanced multilayer
image [EMI]).
The IP base image provides Layer 2+ features, including access control lists, quality of service (QoS),
static routing, and the Routing Information Protocol (RIP). The IP services image provides a richer set
of enterprise-class features, including Layer 2+ features and full Layer 3 routing (IP unicast routing, IP
multicast routing, and fallback bridging). To distinguish it from the Layer 2+ static routing and RIP, the
IP services image includes protocols such as the Enhanced Interior Gateway Routing Protocol (EIGRP)
and the Open Shortest Path First (OSPF) Protocol.
Cisco 3900 Series, Cisco 2900 Series, and Cisco 1900 Series Integrated Services Routers support the
following Cisco EtherSwitch service modules for SM-to-SM or SM-to-ISM communication.
• NME-16ES-1G
• NME-16ES-1G-P
• NME-X-23ES-1G
• NME-X-23ES-1G-P
