CHAPTER
1
Overview of the MWR 1900
The MWR 1900 Mobile Wireless Edge Router is a networking platform optimized for use in mobile
wireless networks. It extends IP connectivity to the cell site and Base Transceiver Station (BTS), and
through a Fast Ethernet interface to the BTS, provides bandwidth-efficient IP transport of voice and data
bearer traffic, as well as maintenance, control, and signalling traffic, over the leased line backhaul
network between the BTS and leased line termination and aggregation node via compression
(cRTP/cUDP) and packet multiplexing (PPPmux and MLPPP). It supports a limited set of interfaces and
protocols, but offers high performance at a low cost while meeting the critical requirements for
deployment in cell sites, including small size, extended operating temperature range, high availability,
and DC input power flexibility.
The MWR 1900 router is designed to be used at a cell site as part of an IP-RAN solution. Figure 1-1
shows the placement of and connections for the MWR 1900 for this application.

100BaseT
pBTS
MWR 1900 IP BTS router pair
In the IP-RAN solution, the BTS site consists of a pair of MWR 1900 routers. The pair of MWR 1900s
provides for an active and standby router for redundancy. A failure of the active MWR 1900 causes the
standby router to take over as the active router for the BTS site.
Each pair of MWR 1900 routers at the BTS site is identical in hardware configuration. They connect to
each other through the BTS via the Fast Ethernet interfaces. The individual backhaul links to an MWR
1900 router are cabled from a single T1/E1 termination block in the BTS, connecting to both the active
and standby routers utilizing a “Y” cable. The redundancy design to control the active/standby

Software Features
transitions of the router pair leverages HSRP to control the relays on the VWIC-2MFT-T1-DIR (or
VWIC-2MFT-E1-DIR) in each router to ensure that the relays on the active router are closed and the
relays on the standby router are open to avoid double termination of the T1 (or E1).
Software Features
The software running on the MWR 1900 platform consists of two components: Cisco IOS software
running on the MIPs-based route processor portion of the MWR 1900 hardware, and microcode running
on the Cisco network processor, also known as “Parallel eXpress Forwarding (PXF).” Because the
MWR 1900 is designed specifically for deployment in an IP-RAN at the BTS, it is customized for
performance, high availability, quality of service, and link efficiency.
Cisco IOS Software
Cisco IOS software functions added to the MWR 1900 router for the IP-RAN application include:
• Redundancy logic—For monitoring Hot Standby Routing Protocol (HSRP) information to
determine the active and standby router and control T1 termination.
Chapter 1Overview of the MWR 1900
• Failover logic—To force a switchover for hardware failures or an over-temperature condition.
• Relay control—To open and close the T1/E1 interfaces on the active and standby routers.
• Diagnostic functions—To monitor the “health” of the standby MWR 1900 router.
Standard Cisco IOS software features supported in the MWR 1900 for the IP-RAN application include:
• IP Fragmentation
• IP Multicast
• IGMP
• MLP, PPP Control Path (IPCP, NCP, LCP, CLNS)
• HSRP
• OSPF
• DHCP
• CDP
• NTP
• SNMP
Network Processor Software
To achieve the required efficiency, the MWR 1900 router has microcode running on the network
processor to offload the fast-path processing of packets. This allows the MWR 1900 router to support
the traffic of up to 4 T1s or E1s (up to 60,000 packets per second) at a targeted 80% processor utilization
while performing UDP/RTP header compression/decompression (cUDP/cRTP) and PPPmux.

Chapter 1Overview of the MWR 1900
The following features are supported in the network processor:
• MAC Classify
• ICMP
• FIB (CEF)
• Load-balancing
• MAC Rewrite
• QoS Matching, including IP Access Lists (Input/Output Security ACLs are not supported), QoS
Group, IP Precedence, IP DSCP, and Input Interface
• QoS Actions, including Set IP Precedence, Set IP DSCP, Set QoS Group, Traffic Shaping, Class
Based WFQ (CB-WFQ), and Low Latency Queuing (LLQ)
• Maintenance of statistics, such as Forwarding, Drop, and Interface
• IPv4
• MLPPP
• MLP, PPP Data Path (MLP LFI is not supported)
• PPPmux
• cRTP/cUDP
Software Features
PPP Multiplexing/Demultiplexing
Encapsulated PPP frames contain several bytes of header information, which adds overhead to a network
that is used to transport PPP frames.
RFC 3153 describes a way to overcome this overhead. On the sending end, a multiplexor concatenates
multiple PPP frames (subframes) into a single, multiplexed frame (superframe). One header is included
in the superframe and the individual PPP subframes are separated by delimiters. On the receiving end,
a demultiplexor uses the delimiters to separate the individual PPP subframes.
The MWR 1900 network processor software conforms to this specification and acts as both a multiplexor
and a demultiplexor.
RTP/UDP Header Compression
RTP is a protocol used for carrying packetized audio and video traffic over an IP network. RTP,
described in RFC 1889, is not intended for data traffic, which uses TCP or UDP. Instead, RTP provides
end-to-end network transport functions intended for applications with real-time requirements (such as
audio, video, or simulation data) over multicast or unicast network services.
In an RTP frame, there is a minimum 12 bytes of the RTP header, combined with 20 bytes of IP header,
and 8 bytes of UDP header. This creates a 40-byte IP/UDP/RTP header. By comparison, the RTP packet
has a payload of approximately 20 to 160 bytes for audio applications that use compressed payloads.
Given this ratio, it is very inefficient to transmit the IP/UDP/RTP header without compressing it.

RFCs 2508 and 2509 describe a method for compressing not only the RTP header, but also the associated
UDP and IP headers. Using this method, the 40 bytes of header information is compressed into
approximately 2 to 4 bytes, as shown in Figure 1-2. Because the frames are compressed on a link-by-link
basis, the delay and loss rate are lower, resulting in improved performance.
The MWR 1900 network processor offloads both the compression and decompression of RTP frames
from the Cisco IOS software.
NoteThe MWR 1900 router can be configured to perform only IP/UDP compression, in which case the
header is reduced from 28 bytes to 2 to 4 bytes.
Redundancy Support
To ensure availability, the backhaul links to an MWR 1900 router are redundantly cabled to the
VWIC-2MFT-T1-DIR/ VWIC-2MFT-E1-DIR cards. This card, designed specifically for the MWR 1900
router, is a modified 2-port T1/E1 Multiflex VWIC with Drop and Insert.The modifications include the
addition of relays to activate the T1/E1 ports. The relays allow “Y” cabling for router redundancy where
the T1/E1 link is not redundant and default to open. The relays are controlled by HSRP/redundancy
protocol between the two routers connected to the same T1/E1.
NoteIf you choose to use the MWR 1900 router in a non-redundant configuration, you must close the
relays on the card using the standalone subcommand. Also, redundancy parameters are processed
when the router is booted up. These parameters cannot be changed “on the fly.”

Chapter 1Overview of the MWR 1900
HSRP
Cisco’s Hot Standby Router Protocol (HSRP) is used to control which router is active and which is
standby. HSRP uses a priority scheme to determine which HSRP-configured router is to be the default
active router. Priority is determined first by the configured priority value, and then by the IP address. In
each case a higher value is of greater priority.
MIB Support
The MWR 1900 supports the following MIBs:

First-Time Configuration
This chapter describes how to use the setup command facility to configure your router. The setup
command facility prompts you to enter information needed to start a router functioning quickly. The
facility steps you through a basic configuration, including local-area network (LAN) and wide-area
network (WAN) interfaces. The following sections are included:
• Before You Begin, page 2-1
• Using the Setup Command Facility, page 2-3
• Configuring Global Parameters, page 2-3
• Completing the Configuration, page 2-5
• Where to Go Next, page 2-6
If you prefer to configure the router manually or you wish to configure a module or interface that is not
included in the setup command facility, proceed to “Chapter 3, “Cisco IOS Software Basics” to
familiarize yourself with the command-line interface (CLI) and then proceed to “Chapter 4,
“Configuring with the Command-Line Interface” for step-by-step instructions.
Before You Begin
This section contains information with which you should be familiar before you begin to configure your
router for the first time, including understanding boot images, understanding interface numbering, and
knowing what you should do before starting your router.
Understanding Boot Images
The first file on the compact flash device in slot0: must be the Cisco IOS software image that you want
to use. If it is not, the MWR 1900 will not be able to boot.
If you need to upgrade or replace the compact flash, be sure to follow the procedures in the Cisco MWR 1900 Mobile Wireless Router Hardware Installation Guide.
Understanding Interface Numbering
Each individual interface (port) on a Cisco MWR 1900 router is identified by number. Figure 2-1 shows
the front of the MWR 1900 with the Fast Ethernet ports and the Voice/WAN Interface Card (VWIC)

The Cisco MWR 1900 router chassis contains the following LAN and WAN interface types:
• Two built-in Fast Ethernet LAN interfaces
• Two slots in which you can install Voice/WAN interface cards (VWICs)
The slot numbers are as follows:
• 0 for all built-in interfaces
• 0 for all VWIC interfaces
The numbering format is:
Interface typeSlot number/Interface number
Interface (port) numbers begin at 0 for each interface type, and continue from right to left.
The two built-in Ethernet 10/100 interfaces are Fast Ethernet 0/0 and Fast Ethernet 0/1.
The slot number for all VWIC interfaces is always 0. (The W0 and W1 slot designations are for physical
slot identification only.) Interfaces in the VWICs are numbered from right to left, starting with 0/0 for
each interface type, regardless of the physical slot in which the VWICs are installed.
For example, if you have a VWIC in each VWIC slot, then the interfaces are Serial 0/0 and Serial 0/1 in
physical slot W0 and Serial 0/2 and Serial 0/3 in physical slot W1. However, if you install a VWIC in
physical slot W1 (leaving slot W0 empty), the interfaces in slot W1 are Serial 0/0 and Serial 0/1. If you
then add a VWIC to slot W0, the interface numbering will shift. The configuration that you created for
interfaces Serial 0/0 and Serial 0/1 will now be applied to the VWIC in slot W0 and you will need to
create a new configuration for the interfaces that you previously configured on W1 (which will now be
Serial 0/2 and Serial 0/3).

Chapter 2First-Time Configuration
Before Starting Your Router
Before you power ON your router and begin to use the setup command facility, make sure you follow
these steps:
Step 1Set up the hardware and connect the console and network cables as described in the Cisco MWR 1900
Router Hardware Installation Guide.
Step 2Configure your PC terminal emulation program for 9600 baud, 8 data bits, no parity, and 1 stop bit.
Using the Setup Command Facility
The setup command facility displays from your PC terminal emulation program window.
To create a basic configuration for your router, do the following:
• Complete the steps in the “Configuring Global Parameters” section on page 2-3.
• Complete the steps in the “Completing the Configuration” section on page 2-5.
Using the Setup Command Facility
NoteIf you make a mistake while using the setup command facility, you can exit and run the facility again.
Press Ctrl-c, and type setup at the enable mode prompt (1900#).
Configuring Global Parameters
Step 1Power ON the router, see the Cisco MWR 1900 Router Hardware Installation Guide.
Messages will begin to appear in your terminal emulation program window.
CautionDo not press any keys on the keyboard until the messages stop. Any keys pressed during this time
are interpreted as the first command typed when the messages stop, which might cause the router to
power off and start over. It takes a few minutes for the messages to stop.

--- System Configuration Dialog ---
At any point you may enter a question mark '?' for help.
Use ctrl-c to abort configuration dialog at any prompt.
Default settings are in square brackets '[]'.
Step 2When the following message appears, enter yes to begin the initial configuration dialog:
Basic management setup configures only enough connectivity
for management of the system, extended setup will ask you
to configure each interface on the system
Would you like to enter basic management setup? [yes/no]:y
Configuring global parameters:
Step 3Enter a host name for the router (this example uses 1900-1):
Configuring global parameters:
Enter host name [Router]: 1900-1
Step 4Enter an enable secret password. This password is encrypted (more secure) and cannot be seen when
viewing the configuration:
The enable secret is a password used to protect access to
privileged EXEC and configuration modes. This password, after
entered, becomes encrypted in the configuration.
Enter enable secret: xxxx
Step 5Enter an enable password that is different from the enable secret password. This password is not
encrypted (less secure) and can be seen when viewing the configuration:
The enable password is used when you do not specify an
enable secret password, with some older software versions, and
some boot images.
Enter enable password: guessme

At this point you can proceed to the following:
• Chapter 3, “Cisco IOS Software Basics” to learn how to use the CLI to configure additional
features.
• Chapter 4, “Configuring with the Command-Line Interface” to complete the configuration of the
interfaces, routing protocols, and other features.
• The Cisco IOS software configuration guide and command reference publications for more
advanced configuration topics.The Cisco 10000 ESR Quality of Service Documents for more
information on configuring QoS. These publications are available on the Documentation CD-ROM
that came with your router, on the World Wide Web from Cisco’s home page, or you can order
printed copies.
