Switch#configure terminal
Switch(config)#hostname S1
S1(config)#interface vlan 1
S1(config-if)#ip address 192.168.1.100 255.255.255.0
S1(config-if)#no shutdown
S1(config-if)#exit
S1(config)#ip domain-name didit.com
S1(config)#crypto key generate rsa
The name for the keys will be: S1.didit.com
Choose the size of the key modulus in the range of 360 to 2048 for your
General Purpose Keys. Choosing a key modulus greater than 512 may take
a few minutes.
How many bits in the modulus [512]: 1024
% Generating 1024 bit RSA keys, keys will be non-exportable...[OK]
S1(config)#username admin password 12345
S1(config)#line vty 0 15
S1(config-line)#transport input ssh
S1(config-line)#login local
S1(config-line)#end
