Deployment and Operation Strategy


The Cisco AS5800 universal access server is the latest entry into Cisco's award-winning AS5x00 series of universal access servers, and provides the highest concentration of modem and integrated services digital network (ISDN) terminations available in a single remote access concentrator product. The Cisco AS5800 is specifically designed to meet the demands of large service providers such as post, telephone, and telegraphs (PTTs), regional Bell operating companies (RBOCs), interexchange carriers (IXCs), and large Internet service providers (ISPs). The Cisco AS5800 complies with Network Equipment-Building System (NEBS) Level 3 requirements as defined by Telcordia Technologies SR-3580, and European requirements are defined by the European Telecommunication Standards Institute (ETSI). Cisco offers a full spectrum of lifecycle-focused support solutions that are complementary to the Cisco AS5800. Further, the Cisco AS5800 voice gateway enables highly scalable deployment of toll-quality voice and fax service over packet networks.

This introductory chapter provides a brief profile and review of the Cisco AS5800 hardware components and functionality, signal and data throughput logic, access server management flow, and Cisco IOS software, as well as an information map to this guide.

Cisco AS5800 Functional Profile

The Cisco AS5800 is a high-density, ISDN and modem WAN aggregation system that provides both digital and analog call termination. It is intended to be used in service-provider dial point-of-presence (PoP) or centralized-enterprise dial environments. The dial-shelf feature cards and the host router shelf communicate over a nonblocking interconnect that supports 100-Mbps full-duplex service.

The Cisco AS5800 supports high density dial aggregation and integrates with Cisco AS5200 and Cisco AS5300 access servers for scaling your service provider network. The Cisco AS5800 also supports high availability of service through online insertion and removal (OIR) capabilities, and redundant power supplies that are hot swappable. All active components within the dial-shelf chassis support OIR, which allows components to be removed or replaced while the system is powered on. Feature cards can be busied-out through the software to avoid loss of calls.

The Cisco AS5800 includes a Cisco 5814 dial shelf and a Cisco 7206 router shelf. If you are installing multiple access servers, a system controller is available, which provides a "single system" view of multiple POPs.

The system controller for the Cisco AS5800 includes the Cisco 3640 router running Cisco IOS software. The system controller can be installed at a remote facility so that you can access multiple systems through a console port or Web interface. It is also possible to download software configurations to any Cisco AS5800 using Simple Network Management Protocol (SNMP) or a Telnet connection using the TFTP protocols. The system controller also provides performance monitoring and accounting data collection and logging.

In addition to the system controller, a network management system (CiscoWorks) with a graphical user interface (GUI) runs on a UNIX SPARC station and includes a database management system, polling engine, trap management, and map integration.

The dial shelf contains ingress interfaces (CT1/CE1/PRI) that terminate ISDN and modem calls, and break out individual calls (DS0s) from the appropriate telco services. Digital or ISDN calls are terminated onboard the trunk card HDLC controllers, and analog calls are sent to modem resources on the modem cards. As a result, any DS0 can be mapped to any HDLC controller or modem module.You can install multiple ingress interface cards of similar or different types. This enables you to configure your systems as fully operative, port redundant, or card redundant, depending on your needs.

Trunk cards and modem cards are tied together across a time division multiplexing (TDM) bus on the dial-shelf backplane. The backplane TDM bus transmits and receives PCM-encoded analog data to and from the modem cards. Then the dial shelf and the router shelf exchange framed packets via a proprietary interconnect cable for further processing.

The dial shelf also contains a DSC card that provides clock and power control to the dial-shelf feature cards. Each dial-shelf controller card contains a block of logic referred to as the common logic and system clocks. This block generates the backplane Stratum-4 compliant 4-MHz and 8-KHz clocks used for interface timing and for the TDM bus data movement. The common logic can use a variety of sources to generate the system timing, including an E1 or T1 input signal from the BNC connector on the dial-shelf controller card front panel. The clock source can also be telco office timing units (BITS clocking) extracted from the network ingress interfaces.

On the DSC card, only one common logic is active at any one time, which is identified by the CLK (clock) LED on the DSC card front panel. The active common logic is user selectable and is independent from each dial-shelf controller card. This ensures that, if a DSC card needs replacing or if the slave DSC card becomes master, clocking remains stable. The selected common logic should not be changed during normal operation, unless related hardware failure is suspected or diagnosed.

Note Software support for redundant DSC cards will be available soon.

The Cisco 7206 router shelf supports call signaling for PRI interfaces; packet processing, and routing; and all commonly used high-speed LAN and WAN interfaces including Fast Ethernet (FE), Asynchronous Transfer Mode (ATM), High-Speed Serial Interface (HSSI), and Fiber Distributed Data Interface (FDDI). These interfaces are supported by common port adapters that are configured on the Cisco 7206 router shelf.

You can install and upgrade software remotely, without affecting current system operation. You can also upload and download configuration files remotely, without affecting current system operation. Remote access is enabled by using SNMP, a Telnet session to a console port on the router shelf, the World Wide Web (WWW) interface, or the optional system controller network management system.

The Cisco AS5800 can dynamically adjust any port to support any user configuration. Individual users can be authenticated as they connect to the system by use of one or more authentication servers using RADIUS and TACACS+ authentication protocols. Primary and backup authentication servers can define user authentication parameters via user domain and the number called. User profile information can also be configured to include time of day, number of simultaneous sessions, and number of B channels used.

A remote LAN user can connect to the Cisco AS5800 via an ISDN line or asynchronous serial connection, be authenticated, and establish a session. In addition to dynamic or static address assignments, this connection requires the traditional Cisco IOS software support for different routing protocols on different ports simultaneously, with virtually no impact on service provider routing tables.

A dial wholesale customer can connect to a Cisco AS5800, and tunnel PPP packet information to a retail service provider using dial virtual private network (dial VPN).

Cisco AS5800 Hardware Review

The Cisco AS5800 consists of two primary system components, the Cisco 5814 dial shelf (DS) and the Cisco 7206 router shelf (RS).

For detailed Cisco 7206 router-shelf hardware specifications and functionality, refer to the following documents:

Cisco 7200 VXR Installation and Configuration Guide, available online at

Cisco AS5800 Access Server Hardware Installation Guide, available online at

For detailed Cisco 5814 dial-shelf hardware specifications and functionality, refer to the following documents:

Cisco AS5800 Access Server Hardware Installation Guide, available online at

Cisco AS5800 Universal Access Server Dial Shelf Card Guide, available online at

Dial Shelf

The Cisco 5814 dial shelf (DS) houses three primary types of circuit cards or boards. Two of these circuit cards, commonly referred to as Feature Module (FM) are trunk cards and modems. They support online insertion and removal (OIR), a feature that permits dynamic replacement without interrupting system activity. These CE1/T1/T3 trunk cards and DMM modem carriers provide the ingress (signal input) interfaces for the Cisco AS5800. The third circuit card type is the dial-shelf controller (DSC) card that provides dial-shelf chassis control and management interfaces.

Dial-Shelf Controller

The Cisco AS5800 dial-shelf controller (DSC) card is located in slots 13 or 14 on the dial-shelf backplane interconnect bus (BIC). It manages all interfaces through the dial shelf, serves as the dial shelf's direct interface to the router shelf, and facilitates the TDM Bus Clock. The DSC card contains two PC card slots that hold the internal flash (bootflash).

Router Shelf

The Cisco 7206 serves as the host router for the Cisco AS5800 and conducts all route/packet route processing functionality of carrying data between the dial shelf and an external network. Full Cisco IOS software functionality is provided on the router shelf. Major components of the Cisco 7206 router shelf are the network processing engine (NPE), dial-shelf interconnect port adaptor (DSI-PA), and the egress interfaces (PAs).

The Cisco 7206 router shelf resides in a standard C7206 chassis, holds the Cisco AS5800's system configuration, performs all Cisco AS5800 routing functions, supports NPE-400, and provides the Cisco AS5800's egress (signal output) interfaces.

Note A virtual console can be opened from the RS to any feature card (including the DSC).

System Architecture

The Cisco AS5800 system architecture consists of backplane bus connections that provide communications between the dial shelf and the host router shelf, monitor system environment conditions, and transmit clock/frame pulses to feature/DS controller cards.

For detailed Cisco 7206 router-shelf functionality and hardware specifications refer to the following documents:

Cisco 7200 VXR Installation and Configuration Guide, available online at

Cisco AS5800 Access Server Hardware Installation Guide, available online at

ROM Monitor

This section describes the Cisco AS5800 ROM monitors on the Cisco 7206 router shelf and the Cisco 5814 dial shelf. ROM monitor is the first software to run when the Cisco AS5800 is powered-up or reset.

The router-shelf ROM monitor operates like a regular Cisco 7206 router ROM monitor. For more information on basic router usage, refer to the Cisco 7206 Installation and Configuration Guide, available online at

The dial-shelf ROM monitor is located on dial-shelf controller cards installed in dial-shelf chassis slots 12 and 13. The dial-shelf ROM monitor is configured to autoboot during system power-up or reset. It always attempts to boot from the first image on Flash memory devices in the following sequence:

PCMCIA slot 0

PCMCIA slot 1

Boot Flash memory

Note During a normal system boot, PCMCIA slots 0 and 1 should remain empty to allow the default image on the boot Flash memory to boot the system.

To boot the system from an image other than the default image, copy the image used to boot as the first file on a PCMCIA Flash memory card and insert the Flash memory card into PCMCIA slot 0 or 1. Reload the dial-shelf controller, which will cause the system to override the default image and reboot the system from the PCMCIA Flash memory card.

Network Topology and Equipment Selection

Figure 1-1 shows the topology devices used to build dialup access environments.

Figure 1-1 Network Topology Elements

Corporate users and ISPs may have identical network topologies:

Remote clients use analog modems to access the IP backbone through the PSTN.

A Cisco AS5800 NAS is used as a point-of-presence (POP) to terminate modem calls and Point-to-Point Protocol (PPP) sessions.

PRI lines are used to provide high throughput (64K) for digital and analog calls. In general, T1 lines can be ISDN PRIs or channelized T1s.

A network element management server maintains and monitors the Cisco AS5800 by using the Network Time Protocol (NTP), system logs (syslog), and the Simple Network Management Protocol (SNMP).

A remote AAA server performs basic user authentication. Corporate users and ISPs can use TACACS+ or RADIUS.

A default gateway forwards packets to the IP intranet and Internet.

An Internet firewall is used to protect the IP intranet from intruders and hackers.

A router provides connectivity between the access subnet and the IP backbone.

For the latest Cisco IOS features and bug fixes, the Cisco AS5800 is upgraded to Cisco AS5800 12.0(4) XL or 12.0(5)T releases.

Note Use a mature Cisco IOS release whenever possible.

Configuration Design Parameters

Before Cisco AS5800 equipment is deployed at your site, define the following configuration design parameters:

IP subnetting and address strategy

Device parameters

Network dial plan

Figure 1-2 IP Subnetting Diagram

Note Uses private RFC 1918 IP addresses. For more information, refer to the Best Current Practice memo available online at

IP Subnetting Plan

The following list describes IP subnetting plan considerations. Identify network names, assigned subnets, and descriptions.

1. Headquarters block (

The headquarters portion of the class-B IP address block for the corporate user or ISP.

The top half of is the IP address pool for the incoming remote-node modem users. The lower half of is reserved for the devices inside the corporate or ISP network.

2. Remotes block (

The upper half of is reserved for remote networks.

3. Headquarters-access (

The headquarters access Ethernet subnet. All access devices are directly connected to this subnet.

If additional access servers and POP-management devices are needed, they are assigned to this IP subnet. This approach simplifies network design.

4. NAS loopback 0 (

Identifies with a unique and stable IP address. One unique IP address from a common block of addresses is assigned to each device in the IP network. This technique facilitates security-filtering easy for the network operations center (NOC).

One class C subnet used for device identification can support 254 distinct devices with unique loopback addresses.

5. NAS loopback 1 (

Hosts a pool of IP addresses for the remote nodes. In this way, one route instead of 254 routes is summarized and propagated to the backbone.

Note Setting up Interior Gateway Protocols (IGP) such as OSPF and EIGRP is outside the scope of this document.

Device Parameters

The following list describes device parameter considerations.

1. Router host names


2. Interface Ethernet 0

3. Interface loopback 0

4. Interface loopback 1

5. IP local address pool

8. IP domain names

Corporate or ISP

9. Network element management server (NTP, SNMP, syslog)

10. SNMP community strings

Read only (RO) = poptarts

Read write (RW) = pixysticks

Dial Plan

The following list describes dial plan setup considerations.

1. PRI telephone numbers assigned to the T1 trunks. One number is used for testing new modem firmware and the other for isolating debugs for specific users.



2. ISDN PRI switch type

Cisco IOS Software Fundamentals

Cisco IOS software provides the capability to configure a Cisco AS5800 using command-line interface (CLI) commands.

Use the following helpful reminders when configuring your Cisco IOS software:

Use the question mark (?) and arrow keys to help enter commands.

Note that each command mode restricts you to a set of commands.

Enter the keyword no before a command to disable a feature; for example, no ip routing.

Save configuration changes to NVRAM so they are not lost in a system reload or power outage.

Use the forward slash (/) command syntax to identify shelf components, interfaces, and port locations (shelf/slot/port). The shelf identification number is the first number identified in the two-bar command syntax.

Note Cisco IOS software is feature specific and licensed on an "as is" basis without warranty of any kind, either expressed or implied. The version of Cisco IOS software used in this manual varies depending on configuration requisites for presentation purposes, and should not be construed as the Cisco IOS software version of choice for your system or internetwork environment. Consult your Cisco sales representative regarding your Cisco IOS requirements.

User Interface Command Modes

Cisco routers are configured from user interfaces, known as ports, which provide hardware connectivity. They are accessed from the console port on a router or Telnet into a router interface from another host. Typical interfaces are Serial 0 (S0), Serial 1 (S1), and Ethernet 0 (E0). Token Ring interfaces are referenced as (T0) and FDDI interfaces use (F0).

Command Modes

When using the CLI, a command interpreter, called EXEC, is employed by the operating system to translate any command and execute its operation. This command interpreter has two access modes, user and privileged, which provide security to the respective command levels. Each command mode restricts you to a subset of mode-specific commands.

User mode provides restricted access and limits router configuration or troubleshooting. At this level, miscellaneous functionality is performed, such as viewing system information, obtaining basic router status, changing terminal settings, or establishing remote device connectivity.

Privileged mode includes user mode functionality and provides unrestricted access. It is used exclusively for router configuration, debugging, setting operating system (OS) parameters, and retrieving detailed router status information.

There are many modes of configuration within privileged mode that determine the type of configuration desired, such as interface configuration (5800-1(config-if)#), line configuration (5800-1(config-line)#), and controller configuration (5800-1(config-controller)#). Each configuration command mode restricts you to a subset of mode specific commands.

In the following command sequence, command prompts are automatically modified to reflect command mode changes. A manual carriage return is implied at the end of each line item.

5800-1> enable
5800-1# configure terminal
5800-1(config)# interface ethernet 0/0/0
5800-1(config-if)# line 0/0/0
5800-1(config-line)# controller t1 0/0/0
5800-1(config-controller)# exit
5800-1(config)# exit
%SYS-5-CONFIG_I: Configured from console by console

The last message is an example of a system response. Press Enter to get the 5800-1# prompt.

Table 1-1 lists common configuration modes. Configure global parameters in global configuration mode, interface parameters in interface configuration mode, and line parameters in line configuration mode.

The following message and prompt appears after a successful configuration copy.


Undoing a Command

To undo a command or disable a feature, enter the keyword no before the command; for example, no ip routing.

Basic Cisco AS5800 Start Up

This section describes how to start up your Cisco AS5800 and configure it using the prompt-driven setup script.

All Cisco AS5800 interfaces are configured by connecting a terminal station or PC to the Cisco 7206 router-shelf console port. This console port is located on the I/O controller front panel, as shown in Figure 1-3.

Figure 1-3 Cisco 7206 Router-Shelf Console Port

To customize your Cisco AS5800 software configuration, you should be familiar with Cisco IOS software. Review the "Cisco IOS Software Fundamentals" section to familiarize yourself with the command-line interface (CLI) commands, then continue with the "Commissioning"chapter for initial step-by-step configuration instructions.

Your Cisco AS5800 requires multiple Cisco IOS software images.

1. Router-shelf image—Cisco IOS software image (c5800-p4-mz) supporting Cisco AS5800 router-shelf functionality, and bundled trunk card and modem card images

2. Router-shelf boot image—Boot helper image (c7200-boot-mz) for Cisco 7206 router shelf

3. Dial-shelf controller image—With boot helper image (dsc-c5800-mz) for Cisco 5814 dial-shelf feature cards

4. Dial-shelf feature board image—Cisco 5814 dial-shelf feature card image (das-c5800-m.ucode) bundled into the router-shelf image

Although four Cisco IOS software images are required, only three software images (Items 1-3) require part numbers for ordering.

The dial-shelf controller image can be upgraded by copying the new image onto a Personal Computer Memory Card International Association (PCMCIA) Flash memory card on the dial-shelf controller card; however, you will soon be able to upgrade the dial-shelf controller image from the network.

Figure 1-4 and Figure 1-5 show a rack-mounted Cisco AS5800 hardware components that require configuration or software monitoring.

Figure 1-5 Cisco AS5800 Universal Access Server—Rear View

Cisco AS5800 First-Time Boot

When you power ON your Cisco AS5800, it goes through the following boot sequence:

1. A power-on self-test diagnostics program verifies basic operation of the CPU, memory, and interfaces.

2. The system bootstrap software executes and searches for a valid Cisco IOS software image. The Cisco IOS software source image is determined by the configuration register setting. The factory-default setting for the configuration register is 0x2102, which indicates that the router should attempt to load a Cisco IOS software image from Flash memory or over the network (depending on boot configuration commands).

3. If, after five attempts (if netbooting) or one attempt (for a Flash memory boot), a valid Cisco IOS software image is not found in Flash memory, the router reverts to boot the ROM mode, which is used to install or upgrade a Cisco IOS software image.

4. If a valid Cisco IOS software image is found, the router searches for a valid configuration file.

5. If a valid configuration file is not found in nonvolatile random-access memory (NVRAM), the router runs the setup script (also called the system configuration dialog), which enables you to configure your software manually. For normal router operation, you must have a valid Cisco IOS software image in Flash memory and a configuration file in NVRAM.

Cisco AS5800 Boot Process

The system boot process consists of two-stages. When the system is first powered on, the trunk cards and modem cards must receive a small image from the dial-shelf controller card, which is then launched by the ROM monitor. This allows the feature cards the ability to "talk" to the dial-shelf controller card and download the bootloader program. Communication is then made on the backplane, that allows each feature cards to talk with the router shelf the Cisco IOS software image. All cards download the bootloader image simultaneously, which then allows them to "talk" across the proprietary Fast Ethernet connection and request the image needed for each card. A hello message is exchanged between the router shelf and the dial shelf.

Because of this two-step boot process, when you first power ON your system, you might not see the feature card LEDs light immediately.

Dial-Shelf Booting

The dial shelf boots up independently from the router shelf. The dial-shelf controller card (DSC) is the first component to boot up. It is set for autobooting from internal Flash memory. If, however, a PCMCIA Flash memory card is present, the DSC tries to first boot from the card, beginning with slot 0.

Using the Setup Script

The setup script is designed to provide you with the minimum requirements needed to get your router running. The setup script enables your system controller to "talk" to the network. You can then configure your system using command-line interface (CLI) commands, or by downloading a predetermined site configuration file.

Before you power ON your Cisco AS5800 and begin using the setup script, verify that you have:

Connected the console cable to the Cisco 7206 router-shelf console port, which is located on the I/O controller front panel

Configured your PC terminal emulation program for 9600 baud, 8 data bits, no parity, and 2 stop bits

Noted the IP address of your Ethernet interface

Noted the set of available IP addresses to be assigned to dial-in IP clients

Noted the host name

Noted the ISDN switch types, framing types, and T1 or E1 line codes

Noted passwords (see the "Passwords" section)

After you verify the information noted above, perform the configuration steps. Continue with the "Setup-Script Initial Configuration" section.

Running the Setup Script

You can run the setup script from the command line at any time using the setup command. The following commands help enable the setup command from the privileged EXEC mode.

Step 1 Enter the enable command.

5800> enable

Step 2 Enter your password. You are in privileged EXEC mode when the prompt changes to 5800#.

Password: password

Step 3 Enter the setup command and press Return. This will initialize the system configuration dialog as described in the previous section "Setup-Script Initial Configuration."

5800# setup


Several passwords are used when configuring your Cisco IOS software. Passwords are used to identify user authorization and permission rights, virtual terminal configuration, and network management software initialization. Most passwords can use the same notation.

You need the following types of passwords when configuring Cisco IOS software:

Enable password—A nonencrypted and, therefore, less secure password.

Enable secret password—A very secure, encrypted password that is used in place of the enable password. Because many privileged-level EXEC commands are used to set operating parameters, we recommend that you use the enable secret password to prevent unauthorized use.

Note The enable password and enable secret password should be different. In both cases, you cannot use a number as the first character. Spaces are valid characters, but only when following valid characters; lead spaces are ignored.

Virtual console password—Enables terminal emulation.

Setup-Script Initial Configuration

When the system is booted for the first time, NVRAM is blank. Because of this, the system software will automatically ask if you want to enter the setup script (system configuration dialog). After you have a configuration, run the setup script again to change it.

The first step is to power ON your Cisco AS5800. The power switch is located on the Cisco 7206 router-shelf rear panel. Be sure to power on the power entry modules (PEMs), which can be accessed from the Cisco 5814 dial-shelf rear panel. If you are using the optional AC-input power shelf, you also need to power on the AC-input power supplies.

Note The messages vary, depending on the Cisco IOS software release and feature set you selected. The screen displays in this section are for reference only and might not exactly reflect the messages on your console.

Step 1 Enter yes at the following prompt if you are ready to continue with the system configuration dialog. If you enter no at this prompt, the system software will return you to the router prompt.

Continue with configuration dialog? [yes/no]: yes

Step 2 Enter the router-shelf identification number, followed by a dial-shelf identification number. Substitute the default values shown with any numeric value between 0 and 9999.

Basic management setup configures only enough connectivity for management of the system, extended setup will ask you to configure each interface on the system

Router Shelf-ID [0]:
Dial Shelf-ID   [1]:

Note The Cisco AS5800 uses a "two-bar" (/) command syntax to identify component (also known as "shelf"), interface, and port locations (shelf/slot/port). The shelf identification number will be the first number to be identified in the two-bar command syntax.

Step 3 Determine whether you want to enter basic management setup configuration and respond to the prompt.

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

Note This example assumes you want to enter the basic management setup configuration. Extended configuration information is explained in Chapter 2 "Operations".

Step 4 Enter the router host name. Substitute your own router host name for the one shown.

Enter host name: 5800-1

Step 5 Enter the enable secret password. The enable secret password is a one-way coded secret used instead of the enable password when it exists. Substitute your own enable secret password for the one shown.

Enter enable secret [<Use current secret>]: shhhh

Step 6 Enter the enable password. The enable password is used when there is no enable secret and when using older software and some boot images.

Enter enable password [public]: guesswho

Step 7 Enter the virtual terminal password. Substitute your own virtual terminal password for the one shown.

Enter virtual terminal password: shhhh1

Step 8 If you plan to use a system controller network management system through which you can administer your Cisco AS5800, enter yes to the following prompt, then enter substitute your own IP address and system controller password when prompted.

Configure System Management? [yes/no]: yes
System Controller IP address:
System Controller password: cisco

Step 9 The system controller supports the Simple Network Management Protocol (SNMP); enter yes at the prompt. The community string is used by the system controller to communicate with its managed shelves. You need to determine a password for this function; the default password is public.

Configure SNMP Network Management? [yes]:
Community string [public]:

Step 10 Enter the interface information used to connect to the system controller at the prompt.

Enter interface name used to connect to the management network from the above interface 
summary: Ethernet0/1/0

Step 11 The system then displays current interface summary information, as shown in Table 1-1, that will help you configure your available egress interfaces.

Configuring interface Ethernet0/1/0:
Configure IP on this interface? [no]:

Table 1-2 Current Interface Summary































1 Any interface listed with OK? value "NO" does not have a valid configuration.

2 The IP address shown requires configuration by the user; it is not a default configuration.

Note If you change a shelf-ID number, you must perform a reload before the new shelf-ID is saved in NVRAM. Use the show version command after you have changed a shelf-ID and performed a reload.

After you enter the interface used to connect to the management network, the system software will automatically display the command script that was just created.

The following configuration command script was created:
hostname 5800-1
enable secret 5 $1$g74v$J87e3eDZdh0wWIR7m4ELy/
enable password shhhh
line vty 0 4
password alwaysup
syscon address cisco
snmp-server community public
no ip routing

interface FastEthernet0/0/0
no ip address
interface Ethernet0/1/0
no shutdown
no ip address 
interface Ethernet0/1/1
no ip address
interface Ethernet0/1/2
no ip address
interface Ethernet0/1/3
no ip address

Verify that the command script just created is correct and enter yes at the prompt if you want to save the configuration. If you enter no at the prompt, you will need to repeat the steps described in Table 1-1 until the desired configuration file is achieved.

[0] Go back to the IOS command prompt without saving configuration
[1] Return back to setup without saving this configuration
[2] Save this configuration to NVRAM and exit.

Selecting choice number [2] builds the configuration into NVRAM as follows:

Building configuration...
Use the enabled mode 'configure' command to modify this configuration.

*Dec 23 12:48:58: %LINK-3-UPDOWN: Interface Ethernet0/1/0, changed state to up

Press Return to display the privileged EXEC router prompt.


You have just completed a basic Cisco AS5800 startup configuration; however, you will probably need to customize this configuration to further meet your site's requirements.
