Getting Started

This chapter describes basic software configuration of the ATM switch router, and includes the following sections:

Note For more software configuration information, refer to the ATM Switch Router Software Configuration Guide. Refer to the ATM Switch Router Command Reference publication for command syntax.

You can name the ATM switch router to distinguish it from other Cisco devices in your network. This feature is especially useful when you have multiple console windows open and you need to distinguish one Cisco device from another. Naming the switch changes the default prompt (Switch>) to a prompt name of your choice; for example, Nevada_Switch>.

Take these steps:

Step Command Purpose

1
Switch> enable

Enter privileged EXEC mode.

2
Switch# configure terminal

Switch(config)#

Enter global configuration mode.

3
Switch(config)# hostname name

Name(config)#

Enter the host name for the switch. Note that the prompt changes to match the host name.
Note The pound sign (#) that follows the host name indicates the current mode of operation and is added automatically.

4
Name(config)# end

Name#

Return to privileged EXEC mode.

Step	Command	Purpose
1	`Switch>` enable	Enter privileged EXEC mode.
2	`Switch#` configure terminal Switch(config)#	Enter global configuration mode.
3	`Switch(config)#` hostname name Name`(config)#`	Enter the host name for the switch. Note that the prompt changes to match the host name. Note The pound sign (#) that follows the host name indicates the current mode of operation and is added automatically.
4	Name`(config)#` end Name`#`	Return to privileged EXEC mode.

Example

Switch> enable
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# hostname Nevada_Switch
Nevada_Switch(config)#

Verify

Switch# more system:running-config

Assigning a Password

Configure an administrative password on the ATM switch router to prevent unauthorized configuration changes.

Take these steps:

Step Command Purpose

1
Switch> enable

Enter privileged EXEC mode.

2
Switch# configure terminal

Switch(config)#

Enter global configuration mode.

3
Switch(config)# enable password password

Enter the enable password.

4
Switch(config)# exit

Switch#

Return to privileged EXEC mode.

Step	Command	Purpose
1	`Switch>` enable	Enter privileged EXEC mode.
2	`Switch#` configure terminal `Switch(config)#`	Enter global configuration mode.
3	`Switch(config)#` enable password `password`	Enter the enable password.
4	`Switch(config)#` exit `Switch#`	Return to privileged EXEC mode.

Example

Switch> enable
Switch# configure terminal
Switch(config)# enable password guessme
Switch(config)# exit
Switch#

Verify

Switch# exit
Switch con0 is now available 
Press RETURN to get started. 
Switch> enable 
Password: guessme 
Switch#

Setting Up Remote Administrative Access

You can configure the Ethernet interface on the processor card (CPU card ) so that you can Telnet to the ATM switch router and configure it remotely. This section describes how to configure the Ethernet port for remote administrative access.

Note For local administrative access, connect a PC or workstation to the console port on the processor card. This requires physical access to the ATM switch router.

Take these steps:

Step Command Purpose

1
Switch> enable

Enter privileged EXEC mode.

2
Switch# configure terminal

Switch(config)#

Enter global configuration mode.

3
Switch(config)# ip route prefix mask ethernet 0[.subinterface]

Configure a static route on the Ethernet interface. If your management station or TFTP¹ server is on a different subnet than the switch, you must configure a static IP route.²

4
Switch(config)# interface ethernet 0

Switch(config-if)#

Enter interface configuration mode on the Ethernet interface.

5
Switch(config-if)# ip address address

Configure an IP address on the Ethernet interface.

6
Switch(config)# end

Switch#

Return to privileged EXEC mode.

¹TFTP = Trivial File Transfer Protocol.
²If you fail to configure a static IP route before installing a new image, you might lose remote administrative access to the switch. If this happens, you can regain access from a direct console connection, although this requires physical access to the console port on the processor card.

Step	Command	Purpose
1	`Switch>` enable	Enter privileged EXEC mode.
2	`Switch#` configure terminal `Switch(config)#`	Enter global configuration mode.
3	`Switch(config)#` ip route prefix mask ethernet 0[.subinterface]	Configure a static route on the Ethernet interface. If your management station or TFTP¹ server is on a different subnet than the switch, you must configure a static IP route.²
4	`Switch(config)#` interface ethernet 0 `Switch(config-if)#`	Enter interface configuration mode on the Ethernet interface.
5	`Switch(config-if)#` ip address address	Configure an IP address on the Ethernet interface.
6	`Switch(config)#` end `Switch#`	Return to privileged EXEC mode.

Example

Switch> enable
Switch# configure terminal
Switch(config)# ip route 172.20.52.0 255.255.255.0 ethernet 0
Switch(config)# interface ethernet 0
Switch(config-if)# ip address 172.20.52.20
Switch(config-if)# end
Switch#

Verify
