This procedure assumes:

• The switch is already configured with an IP address and is reachable within the network.
• There is an account created with Privilege Level 15. To verify this, use the command "show users accounts".

For newer N-Series switches and additional management options, please see HOW10399. 
 

• console>enable
• console#config
• console(config)#enable password MYPASSWORD

3)  To enable SSH, enter the following commands:

• console(config)#crypto key generate rsa
• console(config)#crypto key generate dsa
• console(config)#ip ssh server

If you are having issues with specific commands, ensure you are running the latest firmware version. 
 

Before disabling either telnet or HTTP access, verify SSH or HTTPS access.

 
4)  To disable telnet, run: 

• console(config)# ip telnet server disable

5)  To enable HTTPS, enter the following commands"

• console(config)# crypto certificate 1 generate
• console(config-crypto-cert)#key-generate <512-2048>
• console(config-crypto-cert)#exit
• console(config)# ip http secure-certificate <1 - 2> Instance of the certificate to be activated.
• console(config)# ip http secure-server

This system is capable of the generation and storage of 2 certificates.To generate the second key, replace the number 1 with 2.To activate the second key, use (config)# ip http secure-certificate 2.


6)  To disable HTTP, enter:

• console(config)# no ip http server

7)  After verifying connectivity via SSH or HTTPS, save the configuration by entering:

• console#copy running-config startup-config

After completing these steps, you can expect to receive errors about certificate authenticity. This is due to the certificates and keys being self-generated. This is not an error.
