Switch1<config># int vlan1

// ip address [IP] [subnet mask]

Switch1<config-if># ip address 192.168.100.10 255.255.255.0

// To exit terminal mode

Switch1<config-if># ^Z

// Show current running configuration

Switch1# show run

Step 4:

// Configure default gateway

Switch1<config>#  ip default-gateway 192.168.1.1

Step 5:

// Create user:  TestAdmin   | Password:   Cisco

Switch1<config># username TestAdmin password cisco

Switch1<config># exit


Switch1# exit

Step 6:

Switch1> en

Switch1# config t

// Configure enable password of password1

Switch1<config># enable password password1

Switch1<config># exit

Switch1# exit

Step 7:

// Notice that you'll need to enter a password to enter enable mode

Switch1> en

//  Switch1<config-line>  -- is in line configuration mode
// Switch1<config-line> is for telnet access

Switch1<config-line>#  exit

Switch1<config># line con 0

Switch1<config-line># logging synchronous

Step 10:

Switch1<config># line vty 0 15

Switch1<config-line># password cisco

Switch1<config-line># login

Switch1<config-line># exec-timeout 10

Switch1<config-line># logging synchronous

Switch1<config-line># exit

Switch1<config># line con 0

// This will enable User: TestAdmin | Password: cisco

Switch1<config-line># login local
