Customizing AccessPath-VS3 System Configurations

This chapter describes how to use the Cisco IOS software command-line interface (CLI) to change the host name, password, and the IP addresses used in the Cisco AccessPath-VS3 Packet Telephony Concentrator, in order to alter the standard configurations for your network. The following procedures are described:

Changing the host name and password.
Understanding and assigning IP addresses to each AccessPath-VS3 component
Interface configuration for the following interfaces:
- Ethernet
- Fast Ethernet
- Loopback
- Sc0 interface of the Switch Shelf
Configuring the Open Shortest Path First Protocol (OSPF) Autonomous System.

Follow the procedures in this chapter to configure the components in the AccessPath-VS3 system manually. Many of these configurations can also be created automatically using the Configurator software. For more information, see the Cisco AcessPath-VS3 Packet Telephony Concentrator Software Configuration Quick Start Guide document.

This chapter describes only a small portion of the most commonly used configuration procedures. For advanced configuration topics, see the Cisco IOS configuration and command reference publications. These publications are available on the Documentation CD-ROM that shipped with your AccessPath-VS3 system, on the World Wide Web from Cisco's home page, or you can order printed copies separately.

If you are experienced using the Cisco IOS software, you might find Appendix A, "Sample Configurations," a useful reference.

Note If you did not read Chapter 1, "Cisco IOS Software and the EXEC Facility Fundamentals," and you are not experienced with Cisco router configuration, go to that chapter and read it now. This chapter provides important information you will need to succeed with the configuration.

Configuring the Host Name and Passwords

One of the first configuration tasks you might want to do is configure the host name and set an encrypted password. Configuring a host name allows you to distinguish multiple Cisco devices from each other. Setting an encrypted password allows you to prevent unauthorized configuration changes. Configuring line passwords allows you to prevent unauthorized access to a device.

Table 3-1: Changing the Host Name and Passwords
Step Command Purpose

1
Router> enable

Password: <password>

Router#

Enter enable mode.

Enter the password.

You have entered enable mode when the prompt changes to Router#.

2
Router# config term

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#

Enter global configuration mode. You have entered global configuration mode when the prompt changes to Router(config)#.

3
Router(config)# hostname CMS01

CMS01(config)#

Change the name of the device to a meaningful name. Substitute your host name for CMS01.

4
CMS01(config)# enable secret secret123

Enter an enable secret password. This password provides access to privileged EXEC mode. When a user types enable at the EXEC prompt (CMS01>), that user must enter the enable secret password to gain access to configuration mode. Substitute your enable secret for secret123.

5
CMS01(config)# line vty 0 4

CMS01(config-line)# password cisco

CMS01(config-line)# login

CMS01(config-line)# exit

CMS01(config)#

Enter line configuration mode to configure the virtual terminal ports. The parameter pair 0 4 refers to the range of virtual terminals from vty 0 to vty 63. (There might be a different number of vty lines configured.) When you enter line configuration mode, the prompt changes to CMS01(config-line)#.

Enter a vty password. This password is required to allow Telnet access to a Cisco router. When a user Telnets to the router, that user must enter the vty password to gain access to the EXEC prompt. Substitute your vty password for cisco.

Configure the specified range of vty lines to permit a login with the line password.

Exit back to global configuration mode.

**Table 3-1: Changing the Host Name and Passwords**
Step	Command	Purpose
1	`Router>` enable `Password:` <password> `Router#`	Enter enable mode. Enter the password. You have entered enable mode when the prompt changes to `Router#`.
2	`Router#` config term `Enter configuration commands, one per line. End with CNTL/Z.` `Router(config)#`	Enter global configuration mode. You have entered global configuration mode when the prompt changes to `Router(config)#`.
3	`Router(config)#` hostname CMS01 `CMS01(config)#`	Change the name of the device to a meaningful name. Substitute your host name for CMS01.
4	`CMS01(config)#` enable secret secret123	Enter an enable secret password. This password provides access to privileged EXEC mode. When a user types enable at the EXEC prompt (`CMS01>`), that user must enter the enable secret password to gain access to configuration mode. Substitute your enable secret for secret123.
5	`CMS01(config)#` line vty 0 4 `CMS01(config-line)#` password cisco `CMS01(config-line)#` login `CMS01(config-line)#` exit `CMS01(config)#`	Enter line configuration mode to configure the virtual terminal ports. The parameter pair 0 4 refers to the range of virtual terminals from vty 0 to vty 63. (There might be a different number of vty lines configured.) When you enter line configuration mode, the prompt changes to `CMS01(config-line)#`. Enter a vty password. This password is required to allow Telnet access to a Cisco router. When a user Telnets to the router, that user must enter the vty password to gain access to the EXEC prompt. Substitute your vty password for cisco. Configure the specified range of vty lines to permit a login with the line password. Exit back to global configuration mode.

Verifying the Host Name and Passwords

To verify that you configured the right host name and passwords:

Step 1 Enter the show config command:

CMS01(config)# show config

Using 1888 out of 126968 bytes
!
version XX.X
.
.
.
!
hostname CMS01
!
enable secret 5 $1$60L4$X2JYOwoDc0.kqa1loO/w8/
.
.
.
line vty 0 4
 password cisco
login

: Check the host name and encrypted password displayed near the top of the command output.

Step 2 Exit global configuration mode and attempt to reenter it using the new enable password:

CMS01# exit

.
.
.
CMS01 con0 is now available
Press RETURN to get started.
CMS01> enable

Password: secret123

CMS01#

Step 3 If an interface is configured on the router, open a Telnet session to the router and attempt to enter using the new vty password:

CMS01#  telnet CMS01

Translating "CMS01"...domain server (172.22.5.253) [OK] 
Trying CMS01.yourdomain.com (192.168.1.56)... Open
User Access Verification
Password: cisco

CMS01> 



   

Tips

	Tips

If you are having trouble:

Make sure that the whole range of vty lines are configured with the correct passwords.
Make sure Caps Lock is off.
Make sure you entered the correct passwords. Passwords are case sensitive.

3	`SW01> (enable)`set port enable 2/1-24	Enable all ports connected to Fast Ethernet. In the example, the command is followed by a slot specification and the ports to enable.
4	`SW01> (enable)` disable `SW01>`	Return to unprivileged mode.

Verify the IP Address

To verify you have assigned the correct IP address:

Enter the show interface command:

SW01> show interface

sl0: flags=51<UP,POINTOPOINT,RUNNING>
        slip 0.0.0.0 dest 0.0.0.0
sc0: flags=63<UP,BROADCAST,RUNNING>
        vlan 1 inet 172.16.1.30 netmask 255.255.255.224 broadcast 172.22.16.31
