If you would like to use applications such as putty to manage your HP Procurve switch then you must enanble the SSH protocol on the switch.Before enabling SSH we must create a crypto key, this is used when the SSH client such as putty connects to the switch. The switch uses they key pair along with a generated session key.
First we will generate the crypto keys with the command below. So make sure you are in config mode first.
TechiesSwitch# conf t
Now we are in config context enter the following
TechiesSwitch(config)# crypto key generate ssh rsa bits 1024
Now they key is generated we can enable ssh
TechiesSwitch(config)# ip ssh
Ssh is now enabled and you will be able to connect with your ssh client.
To display the crypto key on the procurve switch then enter the following.
TechiesSwitch(config)# show crypto host-public-key
Finally, to display the status of ssh enter the below.
TechiesSwitch(config)#show ip ssh
SSH on your procurve is now configured.
