[[The No.1 Picture.]] Testing Authentication Without SSH: !--- aaa new-model causes the local username/password on the router !--- to be used in the absence of other aaa statements. aaa new-model username cisco password 0 cisco line vty 0 4 !--- Instead of aaa new-model, the login local command may be used.ip domain-name rtp.cisco.com !--- Generate an SSH key to be used with SSH.
Testing Authentication With SSH: cry key generate rsa ip ssh time-out 60 ip ssh authentication-retries 2
