Cisco AS5300 - Universal Access Server Configuration Manual

CHAPTER

Configuring the Cisco AS5300 Network Access Server

This chapter describes how to configure the Cisco AS5300 network access server (NAS) to receive calls from the Cisco 1604, Cisco 766, and remote modem users as presented in Chapter 1, “Dial Case Study Overview”.

Network Topology, Hardware, and Software Parameters

In the network topology shown in Figure 2-1, the PRI telephone number assigned to the Cisco AS5300 at the central headquarters site (hq-sanjose) is 4085551234. This number is often called the hunt group number, which distributes calls among the available B channels. All four PRI trunks on the Cisco AS5300 are assigned to this number by the PRI provider. The directory numbers for the remote devices are configured on the Cisco AS5300 and then, subsequently configured on the remote devices themselves.

The subnet 10.1.2.0 255.255.255.0 is configured on the Cisco AS5300 and is used for the loopback interface and the local IP address pools as described in Chapter 1, “Dial Case Study Overview”.

Router>

In this case study, the Cisco AS5300 is manually configured by using the Cisco IOS software. The automatic setup script is not used.

Note Enter the show version command to see if the access server is recognizing all its modem

cards. For example, the output field “96 terminal line(s)” indicates that the chassis can find all 96 integrated modems.

Step 2—Configuring the Host Name, Password, and Time Stamps

Assign a host name to the Cisco AS5300, enable basic security, and turn on timestamping.

• Assigning a host name helps you to distinguish between different network devices.

• Enabling passwords helps you to prevent unauthorized configuration changes.

• Setting time stamps helps you to trace debug output for testing connections. Not knowing exactly

when an event occurs hinders you from examining background processes.

To configure the host name, enable password, and time stamps, use the following steps beginning in user EXEC mode:

Step 1 Enter privileged EXEC mode.

Router> enable

Chapter 2 Configuring the Cisco AS5300 Network Access Server

Step 2 Enter global configuration mode. If the logging output generated by the access server interferes with

your terminal screen, redisplay your current command line by using the Tab key.

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z.

Step 3 Assign a host name to the access server. The router prompt changes from Router(config)# to

hq-sanjose(config)#. This host name is typically used during authentication with PPP peers.

Router(config)# hostname hq-sanjose

Step 4 Enter a secret enable password that secures privileged EXEC mode. Make sure to change “letmein” to

your own secret password.

hq-sanjose(config)# enable secret letmein

Step 5 Encrypt passwords in the configuration file for greater security.

hq-sanjose(config)# service password-encryption

Step 6 Enable millisecond time stamping on debug and logging output. Time stamps are useful for detailed

access troubleshooting.

hq-sanjose(config)# service timestamps debug datetime msec hq-sanjose(config)# service timestamps log datetime msec

Task 1—Setting Up Basic Configuration Parameters

Verifying the Host Name, Password, and Time Stamp Configuration

Step 1 Exit out of privileged EXEC mode by using the disable command. The prompt changes from

hq-sanjose# to hq-sanjose>.

Step 2 Enter the enable command followed by your password.

Step 3 Enter the show privilege command to show the current security privilege level:

hq-sanjose# disable hq-sanjose> enable Password: letmein hq-sanjose# show privilege Current privilege level is 15 hq-sanjose#

Tips

If you have trouble:

• Make sure the Caps Lock key is off.

• Make sure you have entered the correct passwords. Passwords are case sensitive.

• Password protection is very important. Enter the show tech-support command to report system

configuration information to Cisco TAC:

hq-sanjose# show tech-support ? ipmulticast IP multicast related information page Page through output password Include passwords rsvp IP RSVP related information <cr>

Chapter 2 Configuring the Cisco AS5300 Network Access Server

Step 3—Configuring Local AAA Security

The Cisco IOS security model to use on all Cisco devices is authentication, authorization, and accounting (AAA). AAA provides the primary framework through which you set up access control on the access server.

• Authentication—Who are you?

• Authorization—What can you do?

• Accounting—What did you do?

In this case study, the same authentication method is used on all interfaces. AAA is set up to use the local database configured on the Cisco AS5300. This local database is created with the username configuration commands.

Note Although configuring your local AAA is not required here, it is considered “best

practices” to do so when first setting up your router. Setting up this local AAA prevents unauthorized access and configuration changes.

Cisco IOS Dial Services Quick Configuration Guide

2-6

Chapter 2 Configuring the Cisco AS5300 Network Access Server

To configure local AAA security, enter the following commands beginning in global configuration mode:

Note Make sure to change “joe-admin” to your own username and “joe-password” to your own

password.

Step 1 Create a local login database and username for yourself. This step also prevents you from getting locked

out of the access server.

hq-sanjose(config)# username joe-admin password joe-password

Step 2 Initiate the AAA access control system. This step immediately locks down login and PPP

authentication.

hq-sanjose(config)# aaa new-model

Step 3 Configure AAA to perform login authentication by using the local username database. The login

keyword authenticates shell/EXEC users.

hq-sanjose(config)# aaa authentication login default local

Task 1—Setting Up Basic Configuration Parameters

Step 4 Configure PPP authentication to use the local database if the session was not already authenticated by

hq-sanjose(config)# aaa authentication ppp default if-needed local

Note After you finish setting up basic security, you can enhance the security solution by

extending it to an external TACACS+ or RADIUS server. This case study describes only local AAA security.

Verifying Local AAA Security Configuration

Step 1 Log in with your username:password.

Step 2 Enter the login command at the EXEC shell prompt. If you get in, the login authentication is working

with your local username. Do not disconnect your access server session until you can log in successfully. (If you get locked out, recover your password by rebooting the access server.)

hq-sanjose# login

Chapter 2 Configuring the Cisco AS5300 Network Access Server

Task 2—Setting Up Asynchronous Shell Services

When you have configured the preliminary parameters such as your host name, password, timestamps and local AAA security on the Cisco AS5300, you can then move on to setting up the asynchronous shell services, which provide access through the Cisco IOS CLI EXEC shell to terminal services (no PPP) for the following tasks:

• Changing passwords

• Accessing menus

• Troubleshooting modem connections

• Accessing other network resources with Telnet

Step 1—Configuring the Fast Ethernet 100BaseT Interface

Assign an IP address, line speed, and duplex mode to the Cisco AS5300’s Fast Ethernet interface, which supports 10- and 100-Mbps speeds.

The default priority search order for autonegotiating the line speed is as follows:

1. 100Base-TX full duplex

2. 100Base-TX half duplex

3. 10Base-T full duplex

4. 10Base-T half duplex

To configure the Fast Ethernet 100Base-TX interface, enter the following commands beginning in global configuration mode:

Cisco IOS Dial Services Quick Configuration Guide

2-8

Chapter 2 Configuring the Cisco AS5300 Network Access Server

Step 1 Configure the IP address and subnet mask on the Fast Ethernet interface.

hq-sanjose(config)# interface fastethernet 0 hq-sanjose(config-if)# ip address 10.1.1.10 255.255.255.0

Step 2 Set autonegotiation for the line speed based on the peer routers, hubs, and switch media.

hq-sanjose(config-if)# speed auto

Step 3 Set autonegotiation for duplex mode.

hq-sanjose(config-if)# duplex auto

Step 4 Bring up the interface. This command changes the state of the interface from administratively down to

up.

hq-sanjose(config-if)# no shutdown %LINK-3-UPDOWN: Interface FastEthernet0, changed state to up

Verifying the Fast Ethernet 100BaseT Interface

Task 2—Setting Up Asynchronous Shell Services

Step 1 Enter the show ip interface brief command to view the interface’s status. The “up” field appears under

the Status and Protocol columns in the displayed output. The fields “

down” or “administratively down”

indicate a connection problem:

hq-sanjose# show ip interface brief fastethernet 0 Interface IP-Address OK? Method Status Protocol FastEthernet0 10.1.1.10 YES manual up up

Step 2 Ping a device in your network, such as a default gateway (backhaul router) or the backbone gateway:

hq-sanjose# ping 10.1.1.1

Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 10.1.1.1, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 4/5/8 ms

Step 3 Enter the show interface fastethernet 0 command to see detailed interface information. Look for the

display field “

FastEthernet 0 is up, line protocol is up.” This means that the access server sees

its own sent and received keepalives.

hq-sanjose# show interface fastethernet 0 FastEthernet0 is up, line protocol is up

Chapter 2 Configuring the Cisco AS5300 Network Access Server

Tips

If you have trouble:

• Make sure the cable connections are not loose or disconnected.

• Make sure you are using the correct IP address.

• An auto-configuration of the Fast Ethernet interface may not work as expected if the Cisco device

is connected to a third-party switch. Using the step-by-step configuration described above may be a good work-around if you have problems getting the interface to work.

Step 2—Configuring the T1 Controllers

Configure the Cisco AS5300’s T1 controllers to allow calls to come into the NAS from the public switched telephone network (PSTN) cloud. You must specify the following information for each controller:

• Framing type

• Line code type

• Clock source

• Timeslot assignments

To configure the controllers, enter the following commands beginning in global configuration mode:

Step 1 Enter your telephone company’s switch type. This example uses primary national ISDN 1.

hq-sanjose(config)# isdn switch-type primary-ni

Cisco IOS Dial Services Quick Configuration Guide

2-10

Chapter 2 Configuring the Cisco AS5300 Network Access Server

Step 2 Enter controller configuration mode for the first T1 controller, which is 0. The controller ports are

labeled 0 through 3 on the quad T1/PRI card.

hq-sanjose(config)# controller t1 0

Step 3 Enter the T1 framing type. This example uses extended super frame.

hq-sanjose(config-controller)# framing esf

Step 4 Enter the T1 line code type. This example uses B8ZS.

hq-sanjose(config-controller)# linecode b8zs

Step 5 Configure the access server to get its primary clock (timing signal) from the T1 line assigned to

controller 0. Line clocking comes from the remote switch.

hq-sanjose(config-controller)# clock source line primary

Step 6 Assign all 24 T1 timeslots as ISDN PRI channels. After you enter this command, a D-channel serial

interface is instantly created (for example S0:23, S1:23, and so on) in the configuration file and the individual B-channel serial interfaces (for example S0:0, S0:1, ...). The D-channel interface functions like a dialer for all the 23 B channels using the controller.

hq-sanjose(config-controller)# pri-group timeslots 1-24

Task 2—Setting Up Asynchronous Shell Services

Step 7 Exit back to global configuration mode.

hq-sanjose(config-controller)# exit

Step 8 Configure the second controller, controller T1 1. Set the clocking to secondary 1. If the line clocking

from controller T1 0 fails, the Cisco AS5300 will receive its clocking from controller T1 1.

hq-sanjose(config#) controller t1 1 hq-sanjose(config-controller)# framing esf hq-sanjose(config-controller)# linecode b8zs hq-sanjose(config-controller)# clock source line secondary 1 hq-sanjose(config-controller)# pri-group timeslots 1-24 hq-sanjose(config-controller)# exit

Step 9 Configure the remaining two controllers. Cisco IOS Release 12.0 and later releases support use of the

clock source line secondary x command. This enables the Cisco AS5300 to continue to receive clock (timing signal) from the telephone company or the next remaining controller if a previous controller goes down. This would not be possible if the remaining T1 controllers were set to internal.

hq-sanjose(config#) controller t1 2 hq-sanjose(config-controller)# framing esf hq-sanjose(config-controller)# linecode b8zs hq-sanjose(config-controller)# clock source line secondary 2 hq-sanjose(config-controller)# pri-group timeslots 1-24 hq-sanjose(config-controller)# exit hq-sanjose(config#) controller t1 3 hq-sanjose(config-controller)# framing esf hq-sanjose(config-controller)# linecode b8zs hq-sanjose(config-controller)# clock source line secondary 3 hq-sanjose(config-controller)# pri-group timeslots 1-24 hq-sanjose(config-controller)# exit hq-sanjose(config#)

If counters are increasing on a specific T1 controller, see the error statistics. Error counters are recorded for a 24-hour period in 15-minute intervals. You must specify a specific controller number to see this detailed information. Focus on the current interval.

In the following example, note that the frame loss and line errors present in data intervals 1 through 4 cleared in the current data interval.

Task 2—Setting Up Asynchronous Shell Services

Note Errors are reported to the controller’s counters each time there is an error.

Therefore, clear the counters by using the clear controller t1 number command before you look for current error statistics. Error counters stop increasing when the controller is configured correctly.

Tips

If you have trouble:

• Make sure the controller reports “up.”

• Check if errors are reported in the current interval.

Step 3—Configuring the Serial Channels to Let Modem Calls Come In

Configure the D channels to allow incoming voice calls to be routed to the Cisco AS5300’s integrated modems. The D channel is the signalling channel that controls the calls coming in on the ISDN B channels.

Later, in the section “Step 1—Configuring Dial-on-Demand Routing” in Task 4, the D-channel configuration can be expanded to also accept ISDN synchronous PPP calls from the remote offices. However, Cisco recommends getting only modem users configured and running at this stage in the process.
