Introduction to the Cisco 3200MARC

The Cisco 3200 Series Mobile Access Routers deliver always on IP connectivity for networks in motion. These routers are intended to be mounted on a vehicle. They support Cisco IOS Mobile Networks, and allows them to hide the IP roaming from the local IP nodes. This allows IP hosts on a mobile network to connect transparently to the parent network while a router is in motion.

For example, an airplane equipped with Cisco 3200 Series Mobile Access Router can fly around the world while passengers stay connected to the Internet. The client computers do not need any specialized software to maintain the connections. This transparent communication is accomplished by Mobile IP devices that tunnel packets to the mobile access router.

The Cisco 3200 Series Mobile Access Router includes a third-party power source, cables, and an enclosure, that are assembled and installed by your system integrator. This document provides the information that you need to configure a completed Cisco 3200 Series Mobile Access Router.

Caveats

Fast Ethernet Support

The FastEthernet 0/0 port on the MARC is a 10/100 Fast Ethernet router port. The FastEthernet 1/0 through 1/3 or 2/0 through 2/3 or 3/0 through 3/3 ports (as determined by the position of the rotary switch) on the 4-port FESMIC and the FastEthernet 1/0 and 1/1 or 2/0 and 2/1 or 3/0 and 3/1 ports on the 2-port FESMIC are 10/100 Fast Ethernet switch ports. The switch ports support all layer 2 features. The routing features supported on the MARC cannot be configured on the FESMIC ports.

Secure MAC Address

Network security is implemented by providing the user with option to make a port secure by allowing only well known MAC addresses to send in data traffic. Secure MAC addresses can be provisioned to allow forwarding of only secure addresses on a FESMIC 10/100 Fast Ethernet port.

IOS Switching Features that are Not Supported

The switching features described in this section are not supported on the Cisco 3200 Series router.

Fast Ether Channel

Fast Ether Channel (FEC), which allows multiple physical Fast Ethernet links to be combined into one logical channel.

SPAN

The Switched Port Analyzer (SPAN), sometimes called port mirroring or port monitoring, selects network traffic for analysis by a network analyzer such as a SwitchProbe device or other Remote Monitoring (RMON) probe.

Voice VLAN

Voice VLAN allows a switch access port to receive an 802.1Q tagged voice packet and native data packet from IP phones with a local switch port that connects to data network. VLAN-capable IP phones are powered directly from the switch port. The FESMIC does not provide in-line power.

Hardware Flow Control

Flow control is not available on the 10/100 Fast Ethernet interfaces of the FESMIC.

CGMP

Cisco Group Management Protocol (CGMP) was implemented by Cisco to restrain multicast traffic in a Layer 2 network. CGMP is not supported due to the lack of common code support.

Sub-interface Support

The sub-interface command is not supported for the virtual layer 3 interface and layer 2 interface on the FESMIC.

Switch Virtual Interface (SVI) is a virtual interface, and Cisco Discovery Protocol (CDP) cannot be enabled on the SVI interface. The IP address can only be configured on the virtual layer 3 interface on the FESMIC.

The class-map command is used to define a traffic class. The match cos traffic command is not available for the SVI interface. Use the mls qos map global configuration command to define the class of service (CoS)-to-Differentiated Services Code Point (DSCP) map.

We recommend that you use a different VLAN identifier for the interface vlan xx and vlan dot1q encap commands when configuring the MARC 10/100 Fast Ethernet port.

Currently, the bridge-group functionality for the IP traffic on the SVI interface is not supported.

IOS Support

Cisco IOS software is packaged in feature sets consisting of software images that support specific platforms. The feature sets available for a specific platform depend on which Cisco IOS software images are included in a release. To identify the set of software images available in a specific release or to find out whether a feature is available in a given Cisco IOS software image, use Feature Navigator or the IOS Software Release Notes.

Feature Navigator

Feature Navigator is a web-based tool that enables you to quickly determine which version of the IOS software images support a particular set of features and which features are supported in a particular IOS image.

Feature Navigator is available 24 hours a day, 7 days a week. To access Feature Navigator, you must have an account on Cisco.com. If you have forgotten or lost your account information, e-mail the Contact Database Administration group at cdbadmin@cisco.com. If you do not have an account on Cisco.com, go to http://www.cisco.com/register and follow the directions to establish an account.

To use Feature Navigator, you must have a JavaScript-enabled web browser such as Netscape 3.0 or later, or Internet Explorer 4.0 or later. Internet Explorer 4.0 always has JavaScript enabled. To enable JavaScript for Netscape 3.x or Netscape 4.x, follow the instructions provided with the web browser. For JavaScript support and enabling instructions for other browsers, check with the browser vendor.

Feature Navigator is updated when major Cisco IOS software releases and technology releases occur. You can access Feature Navigator at http://www.cisco.com/go/fn.

IOS Software Release Notes

Cisco IOS software releases include release notes that provide the following information:

Mobile IOS Features

Network Management Support (Cisco View)

CiscoView is a web-based, graphical device management application that provides monitoring and configuration features for Cisco internetworking products (switches, routers, hubs, concentrators, and access servers). CiscoView aides network management by displaying a physical view of a Cisco device, allowing users to easily interact with device components to change configuration parameters or monitor statistics.

Instead, you can create remote site profiles that contain outgoing call attributes (telephone number, service type, and so forth) on the AAA server. The profile is downloaded by the network access server (NAS) when packet traffic requires a call to be placed to a remote site.

Frame Relay Fragmentation with Hardware Compression	No	IP, IP+
Frame Relay FRF.9 Payload Compression	I	IP, IP+	A stream-oriented, multi-vendor-compatible compression scheme.
Frame Relay IP RTP Priority	No	IP, IP+	The Frame Relay IP RTP Priority feature provides a strict priority queueing scheme on a Frame Relay permanent virtual circuits (PVCs) for delay-sensitive data, such as voice. Voice traffic can be identified by the Real-Time Transport Protocol (RTP) port numbers and classified into a priority queue configured by the frame-relay ip rtp priority command. As a result, voice is serviced as strict priority in preference to other nonvoice traffic.
Frame Relay PVC Interface Priority Queueing	I	IP, IP+	Provides an interface-level priority queueing scheme where prioritization is based on destination PVC rather than packet contents. For example, Frame Relay PIPQ allows you to configure a PVC transporting voice traffic to have priority over a PVC transporting signalling traffic, and a PVC transporting signalling traffic to have priority over a PVC transporting data.

IP Summary Address for RIPv2	Yes	IP, IP+
IP Precedence for GRE Tunnels	Yes	IP, IP+	Copies the Type of Service (TOS) bits to the tunnel header and is used in Mobile IP tunnels. Even with static nodes, with the advent of virtual private network (VPN) and QoS applications, it is also desirable to copy the TOS bits when the router encapsulates the packets using GRE. Routers between tunnel endpoints can take advantage of the QoS features such as weighted fair queuing (WFQ) and weighted random early detection (WRED). Prior to this feature, at generic route encapsulation-based tunnel endpoints the TOS bits (including the precedence bits) were not copied to the tunnel or GRE IP header that encapsulates the inner packet. Instead, those bits were set to zero.
Next Hop Resolution Protocol	I	IP, IP+	Routers, access servers, and hosts can use Next Hop Resolution Protocol (NHRP) to discover the addresses of other routers and hosts connected to a non-broadcast, multi-access (NBMA) network. With NHRP, systems attached to an NBMA network dynamically learn the NBMA address of the other systems that are part of that network, allowing these systems to directly communicate without requiring traffic to use an intermediate hop.

On Demand Routing (ODR)	SB	IP, IP+	On-Demand Routing (ODR) uses Cisco Discovery Protocol (CDP) to propagate the IP prefix.
OSPF	Yes	IP, IP+
