Lab Requirements

1. Setting IP address and Default Gateway of a switch

2. Console, Auxiliary, VTY line password

3. Configuration backup4. Configuration restore5. Using CISCO file system6. Configure Telnet remote access

1. Setting IP address of a switch

IP address of a switch is used to telnet a switch from remote device.

SW1>enableSW1#configure terminalSW1(config)#interface vlan1SW1(config-if)#ip address 192.168.72.11 255.255.255.0SW1(config-if)#no shutdownSW1(config-if)#exitSW1(config)#ip default-gateway 192.168.72.1SW1(config)#exitSW1#disable

2. Console, Auxiliary, VTY line password

Console password:SW1>enableSW1#configure terminalSW1(config)#line console 0SW1(config-line)#loginSW1(config-line)#password ciscoSW1(config-line)#exitSW1(config)#exit

2. Console, Auxiliary, VTY line password (continued)

VTY(Virtual Type Terminal) line password:SW1>enableSW1#configure terminalSW1(config)#line vty 0 ?

<0-15>last line numberSW1(config)#line vty 0 15SW1(config-line)#loginSW1(config-line)#password ciscoSW1(config-line)#exit

2. Console, Auxiliary, VTY line password (continued)

Auxiliary password:SW1>enableSW1#configure terminalSW1(config)#line auxiliary 0SW1(config-line)#loginSW1(config-line)#password ciscoSW1(config-line)#exitSW1(config)#exit

*line auxiliary command is not supported by packet tracer.

3. Configuration backup

SW1>enableSW1#copy running-config tftpAddress or name of remote host []?

192.168.75.5Destination filename [SW1-config]?<press

Enter>Writing…SW1#

4. Configuration restore

SW1>enableSW1#copy tftp running-configAddress or name of remote host []?

192.168.75.5Source filename []?SW1-configDestination filename [running-config]?

<press Enter>Accessing tftp://192.168.75.5/SW1-

config…SW1#

5. CISCO file system

SW1#dirDirectory of flash:/

1 –rw- ……….SW1#dir nvramDirectory of nvram:/
