CHAP T E R

Overview of the Router

The Cisco 1900 Series Integrated Services Routers (ISRs) are modular routers with LAN and WAN connections that can be configured by means of interchangeable interface cards and internal service modules (ISMs). The series currently consists of the 1905, 1921, 1941, and 1941W (wireless) models. The 1941W is Wi-Fi CERTIFIED™ and 802.11a/b/g/n-compliant. The modular design of the routers provides flexibility, allowing you to configure your router according to your needs.

This ISR series has new slots that support next generation Enhanced High-Speed WAN Interface Cards (EHWICs), Internal Services Modules (ISMs, 1941 only), and 2 CompactFlash cards (1941 only). Universal serial bus (USB) ports are available for USB devices, and a USB mini Type-B serial console port is available in addition to the RJ-45 console connector.

Interface Numbering

Each individual interface (port) on a Cisco 1900 series router is identified by a number. The Cisco 1900 series routers contains the following wide-area network (WAN) and local-area network (LAN) interface types:

• Two onboard Gigabit Ethernet (GE) LAN interfaces.

• Two slots in which you can install WICs, VWICs (data only), and HWICs. The Cisco 1905 comes

with a factory installed EHWIC in the right slot.

The numbering format for the slots is interface-type 0/slot-number/interface-number. Tab le 1-6 summarizes the interface numbering. See Figure 1-5 to identify the slot numbers.

Safety Recommendations

Chapter 2 Preparing for Router Installation

Warning

Read the installation instructions before connecting the system to the power source.

Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.

1029

Warning

To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the handles on modules (such as power supplies, fans, or cards); these types of handles are not designed to support the weight of the unit.

Chapter 2 Preparing for Router Installation

• If an electrical accident occurs, proceed as follows:

–

Use caution; do not become a victim yourself.

–

Turn off power to the device.

–

If possible, send another person to get medical aid. Otherwise, assess the victim’s condition and then call for help.

–

Determine whether the person needs rescue breathing or external cardiac compressions; then take appropriate action.

In addition, use the following guidelines when working with any equipment that is disconnected from a power source, but is still connected to telephone wiring or other network cabling:

• Never install telephone wiring during a lightning storm.

• Never install telephone jacks in wet locations unless the jack is specifically designed for it.

• Never touch uninsulated telephone wires or terminals unless the telephone line is disconnected at

the network interface.

• Use caution when installing or modifying telephone lines.

General Site Requirements

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD can occur if electronic printed circuit cards are improperly handled and can cause complete or intermittent failures. Always follow ESD prevention procedures when removing and replacing modules:

• Ensure that the router chassis is electrically connected to earth ground.

• Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to

an unpainted surface of the chassis frame to channel unwanted ESD voltages safely to ground. To guard against ESD damage and shocks, the wrist strap and cord must operate effectively.

• If no wrist strap is available, ground yourself by touching a metal part of the chassis.

Caution For the safety of your equipment, periodically check the resistance value of the antistatic strap. It should

be between 1 and 10 megohms (Mohm).

General Site Requirements

This section describes the requirements that your site must meet for safe installation and operation of your router. Ensure that the site is properly prepared before beginning installation. If you are experiencing shutdowns or unusually high errors with your existing equipment, this section can also help you isolate the cause of failures and prevent future problems.

Site Environment

The Cisco 1900 series router is designed for placement on a desktop, rack-mounted or wall mounted.

The location of your router is an extremely important consideration for proper operation. Equipment placed too close together, inadequate ventilation, and inaccessible panels can cause malfunctions and shutdowns, and can also make maintenance difficult. Plan for access to both front and back panels of the router.

When planning your site layout and equipment locations, remember the precautions described in the

“Site Configuration” section on page 2-4 to help avoid equipment failures and reduce the possibility of

environmentally caused shutdowns. If you are currently experiencing shutdowns or an unusually high number of errors with your existing equipment, these precautions may help you isolate the cause of the failures and prevent future problems.

Statement 1007

the correct voltage, frequency, current draw, and power dissipation for the unit.)

Site Configuration

The following precautions will help you plan an acceptable operating environment for your router and will help you avoid environmentally caused equipment failures:

• Make sure that the room where your router operates has adequate circulation. Electrical equipment

generates heat. Without adequate circulation, ambient air temperature may not cool equipment to acceptable operating temperatures. See the

• Always follow the ESD-prevention procedures described in the “Preventing Electrostatic Discharge

Damage” section on page 2-3 to avoid damage to equipment. Damage from static discharge can

cause immediate or intermittent equipment failure.

• Make sure that the chassis cover and module back panels are secure. All empty interface card slots

must have filler panels installed. The chassis is designed to allow cooling air to flow within it, through specially designed cooling slots. A chassis with uncovered openings creates air leaks, which may interrupt and reduce the flow of air across internal components.

Wireless LAN Considerations

Wireless communication depends upon the propagation of radio waves. Many environmental factors influence radio waves. The factors affecting this. We recommend that you review these factors before you determine a location for the router.

The type of antenna used with your wireless router and its location greatly impact the quality of wireless connections to the router. Cisco 1900 series wireless routers are compatible with three different antenna types—swivel-mount dipole antennas that mounts on the back panel of the router, a wall-mount antenna, and a ceiling-mount antenna.

For more information about antenna coverage and optimal usage, see the following documents:

• Cisco Multiband Swivel-Mount Dipole Antenna

• Cisco Multiband Diversity Omnidirectional Ceiling-Mount Antenna

Inspecting the Router

Cisco Multiband Swivel-Mount Dipole Antenna Installation Notes describes

Do not unpack the router until you are ready to install it. If the final installation site will not be ready for some time, keep the chassis in its shipping container to prevent accidental damage. When you are ready to install the router, proceed with unpacking it.

The router, cables, publications, and any optional equipment that you ordered may be shipped in more than one container.

Inspect all items for shipping damage. If anything appears to be damaged, or if you encounter problems installing or configuring your router, contact customer service. Warranty, service, and support information is in the quick start guide that shipped with your router.

Cable Information and Specifications for Cisco 1900 Series Routers

This document gives cable information and specifications for the console port, auxiliary port, and network ports on your Cisco 1900 series integrated services router.

• Console and Auxiliary Port Considerations, page 3-1

• Preparing to Connect to a Network, page 3-3

Console and Auxiliary Port Considerations

• About Console and Auxiliary Ports, page 3-1

• Console Port Connections, page 3-1

• Auxiliary Port Connections, page 3-3

About Console and Auxiliary Ports

The router includes USB, asynchronous serial and auxiliary ports. The console and auxiliary ports provide access to the router either locally using a console terminal connected to the console port, or remotely, using a modem connected to the auxiliary port. This section provides important cabling information to consider before connecting the router to a console terminal or modem.

The main difference between the console and auxiliary ports is that the auxiliary port supports flow control, whereas the console port does not. Flow control paces the transmission of data between a sending device and a receiving device. Flow control ensures that the receiving device can absorb the data sent to it before the sending device sends more. When the buffers on the receiving device are full, a message is sent to the sending device to suspend transmission until the data in the buffers has been processed. Because the auxiliary port supports flow control, it is ideally suited for use with the high-speed transmissions of a modem. Console terminals send data at slower speeds than modems; therefore, the console port is ideally suited for use with console terminals.

Console Port Connections

The router has an EIA/TIA-232 asynchronous serial console port (RJ-45) and at least one USB Type-A

2.0 compliant ports. See

• EIA/TIA-232 Port, page 3-2

OL-19084-01

Tabl e 1-1 on page 1-8 for a list of ports.

Cisco 1900 Series Hardware Installation

Console and Auxiliary Port Considerations

• USB Serial Console, page 3-2

EIA/TIA-232 Port

Depending on the cable and the adapter used, this port will appear as a data terminal equipment (DTE) or data communications equipment (DCE) device at the end of the cable.

For connection to a PC running terminal emulation software, your router is provided with an RJ-45-to-DB-9 cable.

To connect the router to an ASCII terminal, use the RJ-45-to-DB-9 cable and a DB-9-to-DB-25 adapter (provided).

The default parameters for the console port are 9600 baud, 8 data bits, no parity, and 1 stop bit. The console port does not support mode control. For detailed information about installing a console terminal, see the

For cable and port pinouts, refer to Cisco Modular Access Router Cable Specifications.

USB Serial Console

Chapter 3 Cable Information and Specifications for Cisco 1900 Series Routers

“Connecting to the Console Port with Microsoft Windows” section on page 4-14.

The USB serial console port connects directly to the USB connector of a PC using a USB Type A to 5-pin mini Type-B cable. The USB Console supports full speed (12Mb/s) operation. The console port does not support hardware flow control.

“Connecting to the Console Port with Microsoft Windows” section on page 4-14.

For operation with Microsoft Windows, the Cisco Windows USB Console Driver must be installed on any PC connected to the Console port. If it is not installed, prompts guide you through a simple installation process.

The Cisco Windows USB Console Driver allows plugging and unplugging the USB cable from the console port without affecting Windows HyperTerminal operations. No special drivers are needed for Mac OS X or Linux.

Only one console port can be active at a time. When a cable is plugged into the USB console port the RJ

45 port becomes inactive. Conversely, when the USB cable is removed from the USB port the RJ 45

port becomes active.

Baud rates for the USB console port are 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200 bps.

Note 4-pin mini Type-B connectors are easily confused with 5-pin mini Type-B connectors. They are not

compatible Only the 5-pin mini Type-B can be used.

Auxiliary Port Connections

The router has an EIA/TIA-232 asynchronous serial auxiliary port (RJ-45) that supports flow control. Depending on the cable and the adapter used, this port will appear as a DTE or DCE device at the end of the cable.

For connection to a modem, your router is provided with an RJ-45-to-DB-9 cable and a DB-9-to-DB-25 adapter.

For detailed information about connecting devices to the auxiliary port, see the “Connecting to the

Auxiliary Port” section on page 4-20.

For cable and port pinouts, refer to Cisco Modular Access Router Cable Specifications.

Preparing to Connect to a Network

When setting up your router, consider distance limitations and potential electromagnetic interference (EMI) as defined by the applicable local and international regulations.

The following sections describe network connection considerations for several types of network interfaces:

• Ethernet Connections, page 3-3

Preparing to Connect to a Network

• Serial Connections, page 3-3

• ISDN BRI Connections, page 3-6

• CSU/DSU Connections, page 3-6

Refer to Cisco Modular Access Router Cable Specifications for more information about network connections and interfaces.

Ethernet Connections

The IEEE has established Ethernet as standard IEEE 802.3. The Cisco 1941 Ethernet implementations are as follows:

• 1000BASE-T—1000 Mb/s full-duplex transmission over a Category 5 or better unshielded

twisted-pair (UTP) cable. Supports the Ethernet maximum length of 328 feet (100 meters).

• 100BASE-T—100 Mb/s full-duplex transmission over a Category 5 or better unshielded

About Serial Connections

Serial connections are provided by serial WAN interface cards (WICs). For more information on WICs, refer to

Cisco.com. This document can be accessed online.

Before you connect a device to a serial port, you need to know the following:

• Type of device—data terminal equipment (DTE) or data communications equipment (DCE)—that

you are connecting to the synchronous serial interface

• Type of connector—male or female—that is required for connecting to the device

• Signaling standard that is required by the device

Configuring Serial Connections

Chapter 3 Cable Information and Specifications for Cisco 1900 Series Routers

The serial ports on the serial WICs use DB-60 connectors. Serial ports can be configured as DTEs or DCEs, depending on the serial cable used.

Serial DTE or DCE Devices

A device that communicates over a synchronous serial interface is either a DTE or DCE device. A DCE device provides a clock signal that paces the communications between the device and the router. A DTE device does not provide a clock signal. DTE devices usually connect to DCE devices. The documentation for the device should indicate whether it is a DTE or DCE device. (Some devices have a jumper that allows you to select either DTE mode or DCE mode.)

Ta b l e 3-1 Typical DTE and DCE Devices

Device Type Gender Typical Devices

DTE Male

DCE Female

1. If pins protrude from the base of the connector, the connector is male.

2. If the connector has holes to accept pins, the connector is female.

Table 3-1 lists typical DTE and DCE devices.

• Ter m i n a l

• PC

• Modem

• CSU/DSU

• Multiplexer

Signaling Standards Supported

The synchronous serial ports available for the router support the following signaling standards: EIA/TIA-232, EIA/TIA-449, V.35, X.21, and EIA-530. You can order a Cisco DB-60 shielded serial transition cable that has the appropriate connector for the standard you specify. The documentation for the device that you want to connect should indicate the standard used for that device. The router end of

Cisco 1900 Series Hardware Installation

3-4

OL-19084-01

Chapter 3 Cable Information and Specifications for Cisco 1900 Series Routers

the shielded serial transition cable has a DB-60 connector, which connects to the DB-60 port on a serial WIC. The other end of the serial transition cable is available with a connector appropriate for the standard that you specify.

The synchronous serial port can be configured as DTE or DCE, depending on the attached cable (except EIA-530, which is DTE only). To order a shielded cable, contact customer service. See the

Documentation and Submitting a Service Request” section on page xvi.

Note All serial ports configured as DTE require external clocking from a channel service unit/data service unit

(CSU/DSU) or other DCE device.

Although we do not recommend manufacturing your own serial cables (because of the small size of the pins on the DB-60 serial connector), cable pinouts are provided in the

Cable Specifications.

Transmission Speeds and Distance Limitations

Serial signals can travel a limited distance at any given bit rate; generally, the slower the data rate, the greater the distance. All serial signals are subject to distance limits, beyond which a signal is significantly degraded or is completely lost.

Performing the Initial Configuration on the Router

Verifying the Front Panel LED Indications

The front-panel indicator LEDs described in Tabl e 1-4 provide power, activity, and status information useful during power up.

Performing the Initial Configuration on the Router

Use any of the following tools to perform the initial configuration on the router:

• Using the Cisco Setup Command Facility, page 5-3

• Using Cisco Configuration Professional Express, page 5-6

• Using the Cisco CLI—Manual Configuration, page 5-6

Note Cisco recommends using Cisco Configuration Professional Express to perform the initial configuration

on the router because it provides a web-based graphical-user interface (GUI).

Using the Cisco Setup Command Facility

Cisco Setup Command Facility lets you configure the initial router settings through a configuration dialog. If you see the following messages, the router has booted and is ready for initial configuration using the setup command facility.

--- 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 '[]'.

Would you like to enter the initial configuration dialog? [yes/no]:

If the system configuration dialog message does not appear, a default configuration file was installed on the router prior to shipping. See the

page 5-6 to configure the router.

The setup command facility prompts you to enter the information that is needed to configure a router quickly. The facility steps you through a initial configuration, including LAN and WAN interfaces. For more general information about the setup command facility, see

Configuration Guide, Release 12.4.

Note • The messages that are displayed will vary based on your router model, the installed interface

modules, and the software image. The following example and the user entries (in as examples only.

“Using Cisco Configuration Professional Express” section on

Cisco IOS Configuration Fundamentals

bold) are shown

OL-19084-02

• If you make a mistake while using the setup command facility, you can exit and run the setup

command facility again. Press Ctrl-C, and enter the setup command in privileged EXEC mode (Router#).

Performing the Initial Configuration on the Router

Procedure

Step 1 Enter the setup command facility. From the Cisco IOS CLI, enter the setup command in privileged

EXEC mode, enter the following:

Router> enable Password: <password> Router# setup

--- System Configuration Dialog --Continue with configuration dialog? [yes/no]:

Step 2 To proceed using the setup command facility, enter yes.

Continue with configuration dialog? [yes/no]:

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 3 Proceed using basic management setup, which configures only enough connectivity:

Would you like to enter basic management setup? [yes/no]: yes

Chapter 5 Configuring the Router

Step 4 Enter a hostname for the router:

Configuring global parameters: Enter host name [Router]: myrouter

Step 5 Enter an enable secret password. This password is encrypted (for more security) 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: cisco

Step 6 Enter an enable password that is different from the enable secret password. This password is not

encrypted (and is 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: cisco123

Step 7 Enter the virtual terminal password, which prevents unauthenticated access to the router through ports

other than the console port:

The virtual terminal password is used to protect access to the router over a network interface. Enter virtual terminal password: cisco

Step 8 Respond to the following prompts as appropriate for your network:

Configure SNMP Network Management? [no]: yes Community string [public]:

Configuring the Router Hostname

The hostname is used in CLI prompts and default configuration filenames. If you do not configure the router hostname, the router uses the factory-assigned default hostname “Router.”

Do not expect capitalization and lower casing to be preserved in the hostname. Uppercase and lowercase characters are treated as identical by many Internet software applications. It may seem appropriate to capitalize a name as you would ordinarily do, but conventions dictate that computer names appear in all lowercase characters. For more information, see the RFC 1178, Choosing a Name for Your Computer.

The name must also follow the rules for Advanced Research Projects Agency Network (ARPANET) hostnames. They must start with a letter, end with a letter or digit, and have as interior characters only letters, digits, and hyphens. Names must be 63 characters or fewer. For more information, see the RFC 1035, Domain Names—Implementation and Specification.

Configuring the Enable and Enable Secret Passwords

To provide an additional layer of security, particularly for passwords that cross the network or are stored on a TFTP server, you can use either the enable password command or enable secret command. Both commands accomplish the same thing—they allow you to establish an encrypted password that users must enter to access privileged EXEC (enable) mode.

Restrictions

SUMMARY STEPS

We recommend that you use the enable secret command because it uses an improved encryption algorithm. Use the enable password command only if you boot an older image of the Cisco IOS software or if you boot older boot ROMs that do not recognize the enable secret command.

For more information, see the “Configuring Passwords and Privileges” chapter in the Cisco IOS Security

Configuration Guide. Also see the

Cisco IOS Password Encryption Facts tech note and the Improving

Security on Cisco Routers tech note.

If you configure the enable secret command, it takes precedence over the enable password command; the two commands cannot be in effect simultaneously.

Specifying a Default Route or Gateway of Last Resort

This section describes how to specify a default route with IP routing enabled. For alternative methods of specifying a default route, see the

Configuring a Gateway of Last Resort Using IP Commands tech note.

The Cisco IOS software uses the gateway (router) of last resort if it does not have a better route for a packet and if the destination is not a connected network. This section describes how to select a network as a default route (a candidate route for computing the gateway of last resort). The way in which routing protocols propagate the default route information varies for each protocol.

Configuring IP Routing and IP Protocols

For comprehensive configuration information about IP routing and IP routing protocols, see Cisco IOS

IP Routing Protocols Configuration Guide, Release 12.4T.

You can configure integrated routing and bridging (IRB) so the router can route and bridge simultaneously. The router will act as an IP host on the network whether routing is enabled or not. To read more about IRB see the following URL on Cisco.com,

is disabled, refer to the Configuring a Gateway of Last Resort Using IP Commands tech note.

A router might not be able to determine the routes to all other networks. To provide complete routing capability, the common practice is to use some routers as smart routers and give the remaining routers default routes to the smart router. (Smart routers have routing table information for the entire internetwork.) These default routes can be passed along dynamically, or can be configured into the individual routers.

Most dynamic interior routing protocols include a mechanism for causing a smart router to generate dynamic default information that is then passed along to other routers.

5-14

If a router has an interface that is directly connected to the specified default network, the dynamic routing protocols running on the router will generate or source a default route. In the case of RIP, the router will advertise the pseudonetwork 0.0.0.0. In the case of IGRP, the network itself is advertised and flagged as an exterior route.

A router that is generating the default for a network also may need a default of its own. One way a router can generate its own default is to specify a static route to the network 0.0.0.0 through the appropriate device.

Cisco 1900 Series Hardware Installation

OL-19084-02

Chapter 5 Configuring the Router

Gateway of Last Resort

When default information is being passed along through a dynamic routing protocol, no further configuration is required. The system periodically scans its routing table to choose the optimal default network as its default route. In the case of RIP, there is only one choice, network 0.0.0.0. In the case of IGRP, there might be several networks that can be candidates for the system default. The Cisco IOS software uses both administrative distance and metric information to determine the default route (gateway of last resort). The selected default route appears in the gateway of last resort display of the show ip route EXEC command.

If dynamic default information is not being passed to the software, candidates for the default route are specified with the ip default-network global configuration command. In this usage, the ip default-network command takes an unconnected network as an argument. If this network appears in the routing table from any source (dynamic or static), it is flagged as a candidate default route and is a possible choice as the default route.

If the router has no interface on the default network, but does have a route to it, it considers this network as a candidate default path. The route candidates are examined and the best one is chosen, based on administrative distance and metric. The gateway to the best default path becomes the gateway of last resort.

Examples

Copying the Startup Configuration to a TFTP Server: Example

The following example shows the startup configuration being copied to a TFTP server:

Router# copy nvram:startup-config tftp:

Remote host[]? 172.16.101.101

Name of configuration file to write [rtr2-confg]? <cr> Write file rtr2-confg on host 172.16.101.101?[confirm] <cr> ![OK]

Copying from Flash Memory to a TFTP Server: Example

The following example shows the use of the show {flash0|flash1}: command in privileged EXEC to learn the name of the system image file and the use of the copy {flash0|flash1}: tftp: privileged EXEC command to copy the system image (c3900-2is-mz) to a TFTP server. The router uses the default username and password.

Note To avoid losing work you have completed, be sure to save your configuration occasionally as you

proceed. Use the copy

running-config startup-config command to save the configuration to

NVRAM.

Verifying the Initial Configuration

To verify the initial configuration on the router, enter the following commands in the Cisco IOS:

• show version—Displays the system hardware version; the installed software version; the names and

sources of configuration files; the boot images; and the amount of installed DRAM, NVRAM, and flash memory.

• show diag—Lists and displays diagnostic information about the installed controllers, interface

processors, and port adapters.

• show interfaces— Shows interfaces are operating correctly and that the interfaces and line protocol

are in the correct state—up or down

• show ip interface brief— Displays a summary status of the interfaces configured for IP protocol.

• show configuration— Verify that you have configured the correct hostname and password.

When you have completed and verified the initial configuration, the specific features and functions are ready to be configured. See the

Cisco 1900 Series, 2900 Series, and 3900 Series Software Configuration

Guide.

CHAP T E R

Getting Software Licenses for the Router

The Integrated Services Router Generation 2 (ISR G2) platforms offer a new Universal Cisco

Internet Operating System (IOS) software image. The Universal image and its licensing provisions provide greater flexibility to deploy new features while also improving visibility and management of existing licenses on routers in the network.

When you order a new ISR G2, it is shipped with the software image and the corresponding permanent licenses for the packages and features that you specified, preinstalled. The software does not need to be activated or registered prior to use.

Use the Cisco management application such as Cisco License Manager (CLM), or use the Cisco IOS command show license feature to determine the licenses activated on your system.

The router comes with an evaluation license, also known as a temporary license, for most packages and features supported on the router. To try a new software package or feature, activate the evaluation license for that package or feature.

This chapter contains the following sections:

• Activating a New Software Package or Feature, page 6-1

• RMA License Transfer, page 6-2

• Additional Information, page 6-3
