System Configuration and Setup

System Configuration and Setup

This chapter describes procedures to start the Cisco 3800 system, configure interfaces, and set parameters. It contains the following sections:

Starting Your System for the First Time

When you have successfully installed your Cisco 3800 series system, take the following steps to start it:

Step 1 Connect a diagnostic and maintenance terminal to the Combo card's RJ-45 SRV port.

Step 2 Set the power switch of the Cisco 3800 system to the ON position, starting the system for the first time. Each time you start the system, it performs a sequence of diagnostic routines. The green status LED flashes to indicate the following:

As the system starts, a series of self-diagnostic routines executes and the Combo card's main status LED displays as follows:


Step 3 See the following section, "ROM Monitor," if your terminal boots with the following prompt:

Step 4 If diagnostics pass and your system boots the Cisco IOS software successfully, the following screen displays:

Step 5 Press Return to access the System Configuration Dialog.

Step 6 Enter y and press Return to proceed.

Now you are ready to set up your system's ports and trunks. Proceed to the section "Configuring Ports."

ROM Monitor

Note ROM monitor mode is for testing only. If you have questions about ROM monitor mode and its use, contact customer service.

Your system may boot in ROM monitor mode, characterized by the following prompt:

rommon 1 >

Exit ROM monitor mode to configure your system by following these steps:

Step 1 At the ROM monitor prompt, enter the following command:

A series of boot-up messages display the length of time remaining for your system to start.


Step 2 Wait 20 minutes or so as the system starts. You should now have Cisco IOS software loaded.

Step 3 If you are brought back to the ROM monitor prompt instead of the Cisco IOS software prompt, your system has been specifically configured to boot the ROM monitor software. You must reconfigure your system to boot the software image loaded in Flash memory by entering the command to configure a register:

Step 4 You now see a script that changes the configuration. This script displays the current configuration summary:

Step 5 At the prompt, indicate that you want to change the configuration:

Step 6 At the prompt, indicate that you want to disable diagnostics mode:

Step 7 Press Return to select the default responses until you are asked whether you would like to change the boot characteristics, then respond yes:

Step 8 Enter the number 2, indicating that the Cisco IOS software image should boot:

The configuration summary displays the changes you have made.


Step 9 Enter the boot command again and wait for the system to bring you to the Cisco IOS prompt.

Configuring Ports

When you define your network's configuration scheme, refer to Figure 2-1, which illustrates which device types attach to which ports.


Figure 2-1: System Software Ports and Connections



Note All port definitions require a slot and a port number. For example, the port serial 0/0 is the first serial port in the first slot. In the three-slot chassis, slots are numbered from bottom to top.

Now you are ready to set up your system's ports and trunks by entering the initial configuration dialog. The tasks for configuration are:

View the Interface Summary

Step 1 Press Return or enter yes at the initial configuration dialog prompt. The system responds:

Step 2 Press Return or enter yes. The system responds with a list of known ports:

Step 3 Set global parameters and configure your serial and Ethernet ports. If one of the Cisco IOS software interfaces you expect to see does not display in the list of known ports, shut down your Cisco 3800 series system and double-check connections and backplane seating.

Set Up Global Parameters

To set up global parameters, which include host name, password, SNMP management, and IP information, follow these steps:

Step 1 Configure the global parameters. A typical configuration follows:

Step 2 As prompted, enter an enable password and press Return.

Caution  For maximum security, be sure the enable and enable secret passwords are different. If you enter the same password for both, the system accepts your entry, but warns you to enter a different password.

Step 3 In response to the following prompt, enter a virtual terminal password:

Step 4 Press Return. The following message displays:

Step 5 Enter no to refuse the Simple Network Management Protocol. You will configure SNMP later. You can use your own pre-configured SNMP dialog.

Step 6 In the following example, the system is configured for AppleTalk, IP and IPX. Configure the appropriate protocols for your device:

Proceed to the next section to set up Ethernet interfaces to LANs.

Set Up Ethernet Interfaces to LANs

Ethernet interfaces allow you to connect to LANs. To configure the Ethernet interface parameters, you need to know your network addresses. Take the following steps to set up your Ethernet interface configuration:

Step 1 Press Return or enter y to configure an Ethernet interface:

Step 2 Determine which protocols you want to support on the Ethernet interface and enter the appropriate responses. The following example configures for AppleTalk, IP, and IPX:

Step 3 To configure additional Ethernet interfaces, repeat this procedure.

Step 4 To display the interfaces you have configured, enter the show interface command:

Step 5 When you press Return, you see the current configuration:

Proceed to the next section to set up serial interfaces to WANs.

Set Up Serial Interfaces to WANs

Serial interfaces allow you to connect to WAN). Follow these steps to configure your serial interfaces:

Step 1 Press Return or enter yes to configure the first serial interface:

Step 2 Determine which protocols you want to support on the serial interface and respond as appropriate. In the following example, the system is being configured for AppleTalk, IP, and IPX:

Step 3 Configure additional serial interfaces, as follows:

Step 4 The configuration you entered displays and you are asked if you want to use it. Enter yes to save the configuration in the startup file:

Step 5 Refer to the section "Cisco IOS Software Basics" in the chapter "About the Cisco 3800 and Cisco IOS Software" for more information about Cisco IOS software.

Step 6 To display the interface you have configured, use the show interfaces command:

Step 7 Press Return to display a list of existing interfaces and their configurations:

Step 8 Check to make sure your specified settings are completed accurately.

You are now ready to set up voice ports.


Set Individual Characteristics for a Voice Port

You must properly configure DIP switches SW1, SW2, and SW3 on the Combo card as described in the chapter "Installing Cisco 3800 Cards" in the publication Cisco 3800 Series Hardware Installation for line impedance, 2/4 wire E&M, E&M type configuration, FXS ground start/loop start, and/or FXO ground start/loop start before you set the characteristics as described in this section.

Depending on your DIP switch configuration, Cisco IOS software prompts you to set different characteristics. This example has both voice ports set as E&M.

The individual characteristics that can be set up for a voice port are as follows:

Voice ports do not display in the show interface listing described for serial and Ethernet ports. Take the following steps to display and configure voice ports:

Step 1 Display the currently defined voice port states using the show command:

Step 2 When you press Return, the current settings of the voice ports are displayed--for example, as follows:

Step 3 To change a voice port's attributes--for example, to enable pulse dialing instead of DTMF--enter configuration mode:

Step 4 Press Return. Note how the prompt changes to indicate configuration mode:

Step 5 Specify that you want to configure a specific voice port by putting a slash between slot and port number (port and slot numbering begins with 0):

Step 6 When you press Return, note how the prompt changes to indicate that you are configuring a voice port:

Step 7 Although default settings are in place and will generally work without you changing anything, you can modify the following characteristics:

Step 8 Specify the attribute of the selected voice port you want to configure by entering the appropriate syntax. Depending on whether your interface type is FXS, FXO (connecting two Cisco 3800 systems) or E&M (a Cisco 3800 connected to an IGX or IPX switch), configurable parameters will change.

Step 9 If your system is set up as a switched virtual circuit, set the SVC parameter for the voice port as follows:

dial-peer-tag is the numeric identifier for this peer. Choose a value between 1 and 10,000.


This gives your voice port dial tone. You won't need this for a direct connection between two Cisco 3800 systems.


Set Up a Dial Peer

Step 1 Associate your voice port with a dial peer by entering the following syntax at the global configuration mode prompt:

tag is a local value only between 1 and 10,000.


Step 2 Press Return and, at the conf-dial prompt, select the specific voice port:

Step 3 Press Return. You can now set the following attributes of the dial peer using the specified syntax:

or


Step 4 Assign the dial peer to a hunt group. This is a reference number between 1 and 1000 for a hunt group:

Step 5 Assign a destination pattern, the E.164 number or prefix to associate with this dial peer. All peers in the same peer group ID must use the same destination pattern:

You have now set up the voice port and voice peer. The following sections provided detailed command line information for configuring other parameters.

Set the Input/Output Gain

Set the selected voice interface's input or output gain to alternate from its 0 dB default setting using the following syntax:

gain in gain-level
gain out gain-level

gain-level is measured in decibels, from -14 to +6.

Set the Dial Type

Set the selected interface's dial type to alternate from its DTMF default setting using the following syntax:

dial-type { pulse | dtmf }

pulse--Pulse dialing. Dial digits are transmitted using a series of pulses.

dtmf--Dual tone multifrequency dialing, also known as touch-tone.

Set the Voice Compression Encoding Algorithm

Configure the interface with the appropriate voice compression encoding algorithm using the following syntax:

coder { adpcm32k | adpcm24k | ldcelp16k | csacelp8k }
Note The actual encoder being used for a call may be different as a result of call negotiations.

adpcm32k--ITU G.726 standard, 32k rate

adpcm24k--ITU G.726 standard, 24k rate

ldcelp16k--ITU G.728 standard, 16k rate (default)

csacelp8k--ITU G.729 standard, 8k rate

Set the Fax Rate

Configure the fax transmit rate with the following syntax. All choices are bit rates, except for voice, which uses the currently configured voice rate:

fax-rate { voice | r2400 | r4800 | r7200 | r9600 | r14400 }

Set Timing

You can require a voice interface to connect to a variety of voice products with different timing to detect digits--for example, pulses and winks--using the following syntax:

timing { digit | inter-digit | pulse | pulse-inter-digit | clear-wait | wink-wait | wink-duration | delay-start | delay-duration } amount_of_time

digit--DTMF digit duration in milliseconds (50-500, default 100).

inter-digit--DTMF interdigit duration in milliseconds (50-500, default 100).

pulse--Pulse dialing rate in pulses per second (pps) (10-20, default 20).

pulse-inter-digit--Pulse dialing interdigit timing in microseconds (100-1000, default 500).

clear-wait--Time of inactive seizure signal to declare a call cleared (200-2000, default 500).

wink-wait--Maximum wink wait duration for wink start signaling (10-100, default 50).

wink-duration--Maximum wink duration for wink start signaling (10-100, default 50).

delay-start--Timing of the generation of a delay start signal from detection of incoming seizure (10-100, default 50).

delay-duration--Maximum delay signal duration for delay dial signaling (10-100, default 50).

amount_of_time--The value in seconds.

Set Speed Dial with Number Expansion

Set a translation between an abbreviated speed dial number and a full E.164 (telephone) number:

[ no ] number-expansion dialed_number translation

dialed_number--A simple regular expression uses digits, periods (.) to indicate placeholders, and asterisks (*) to indicate wildcards.

translation--An E.164 number or prefix is used to translate the dialed number. If this translation is a prefix, it will be prepended to all nonspecified digits in the dialed number pattern. For example, for the number expansion 7.... +1408527, and the dialed number is 74321, the resulting translation would be +14085274321.

Note You can use the clear voice-port { number } command to reset all voice interface parameters to default values.

Set Voice PVCs for Switched Voice

Use the following global configuration command to set up a voice PVC:

connect { v0 | v1 } dst-addr switch-group { active | passive }

A maximum of 100 connections can be made using the connect command. For example:

connect s0/1 dlci 100 s0/3 conn 52

Two examples of setting up a voice PVC for switched voice are as follows:


  1. To set up a PVC between two voice ports on the same Cisco 3800 system: 
connect voice 10 voice 11


  1. To set up a PVC between a voice port and a connection ID on an FTC trunk: 
connect voice 10 s0/3 connection-id 24
Note Use even connection ID numbers when setting up voice PVCs. Using an odd connection ID number results in the error message INVALID_DEST_VC.

Set Up FTC Trunks to the Backbone or Switch

The FTC trunk connects the Cisco 3800 to the FTC or FTM card on the IGX or IPX switch, or it connects two Cisco 3800 systems back to back. The FTC trunk also offers additional functionality for IGX or IPX systems that don't support Cisco 3800 access devices. Limited functionality on a public Frame Relay network is also offered.

Before you begin to set up an FTC trunk, you need the following information:

There are two ways to set up an FTC trunk from a Cisco 3800 system:

Methodologies for both types of configurations vary.

Cisco 3800 to an IGX or IPX FTC or FTM Card through a Frame Relay Cloud

Figure 2-2 illustrates a connection from a Cisco 3800 to an IGX or IPX FTC or FTM card through a Frame Relay cloud.


Figure 2-2: Connection through a Frame Relay Cloud



When connecting a Cisco 3800 to an FTC or FTM card, make sure the following are set:

Back-to-Back Configuration


Figure 2-3: Connection Back to Back



When connecting a Cisco 3800 to another Cisco 3800, make sure the following are set:

Set FTC Encapsulation

To set a serial port as an FTC trunk, in interface configuration mode, enter the following command:

encapsulation ftc-trunk

Set FTC Management Protocol to Normal

Setting the FTC management protocol to normal sets up the trunk to run a standard FTC trunk protocol.

ftc-trunk management-protocol { normal | inverted }

Select FTC Management DLCIs

The management DLCI specifies the DLCI to be used to carry the management protocol frames. In addition, if Frame Relay DLCI and voice DLCI parameters are not set, management DLCI will also be used for those types of traffic.

Set the back-to-back FTC trunk's Management DLCI as follows:

Use the following syntax:

ftc-trunk management-dlci dlci

dlci can be a value in the range of 16-991.

Set Clock Rate

To set the back-to-back FTC trunk's clock rate, follow these guidelines:

The following clock rates are displayed when you invoke the command clock rate:

robot1 (config-if)# clock rate
speed (bits per second)
1200     256000
2400     384000
4800     500000
9600     512000
14400    600000
19200    700000
28800    768000
32000    800000
38400    1000000
56000    1200000
57600    1300000
64000    1400000
72000    1600000
115200   1800000
125000   2000000
128000   3000000
148000   4000000
250000
<300-8000000> Choose clock rate from list above

Select the clock rate you want, as follows:

robot1 (config-if)# clock rate speed

Speed is set in bits per second. To set no clock rate, enter the following:

robot1 (config-if)# no clock rate

Bandwidth

To set the back-to-back FTC trunk's bandwidth, follow these guidelines:

To set bandwidth, enter the following command:

robot1 (config-if)# bandwidth speed

speed is set in kilobits per second.

Note Use the bandwidth command to properly manage traffic only when the clockrate is set to no clockrate.

Example FTC trunk setup

Step 1 Specify a serial interface that has an encapsulation of ftc-trunk--for example, as follows:

Step 2 Specify the media type:

Step 3 Specify which FTC trunk DLCI will carry management traffic using the following command:

dlci-number is a DLCI with a value ranging from 16 to 1007.


Step 4 Specify which FTC trunk DLCI will carry voice traffic using the following syntax:

dlci-number is a DLCI with a value ranging from 16 to 1007.


Step 5 Specify which FTC trunk DLCI will carry Frame Relay traffic using the following command:

dlci-number is a DLCI with a value ranging from 16 to 1007.


Step 6 Specify the management protocol, as follows:

This example sets up two serial ports as FTC trunks:


Step 7 Specify any session trunks on the FTC trunk using the following command:

cid can be 1-252.


Step 8 The FTC trunk is initialized in the shutdown state. At initial setup you must specify the FTC trunk to be in the no shutdown state by entering the following command:

Configure Connection to a Cisco 3800 ERM

See the publication Cisco 3800 Expansion Router Module Installation and Configuration Guide for an explanation of how to connect a Cisco 3800 ERM.

Configure SNMP

See the Cisco IOS configuration guide and command reference publications for guidelines to configure SNMP. The Cisco IOS Software Command Summary is a good reference.

Configure T1/E1 ports

The Cisco 3800 system supports T1 and E1 in two ways:

If either of these conditions is not met, the following error message is displayed:

%Insufficient resources to create channel group

See the Cisco IOS configuration guide and command reference publications to configure T1/E1 ports. The Cisco IOS Software Command Summary is a good reference.

Saving Configuration Changes

Whenever you make changes to the Cisco 3800 system's configuration, you must save the changes to memory or they will be lost when the system is reset or the power goes down:

Europa> enable
Europa# write memory

Two types of configuration files exist: the running or current operations configuration file and the startup configuration file. The running configuration file is stored in RAM; the startup configuration file is stored in NVRAM. To display the current running configuration, enter the show running-config command. Enter the copy running-config startup-config command to make your startup configuration the running configuration.

To save configuration changes to NVRAM, enter the following commands at the privileged EXEC prompt (#):

Europa# copy running-config startup-config

Verifying the Network's Connectivity

When you have installed and configured a Cisco 3800 system, use the following commands to verify network connectivity from user EXEC mode:

Example Configuration

The configuration illustrated in Figure 2-4 connects two Cisco 3800 systems named Europa and Ganymede through an IGX switch named Socks using encapsulated FTC trunks. The IPTV client server sends live or prerecorded digital and audio streams simultaneously to an unlimited number of users over any IP-based LANs or WANs.
