You can access the ASA appliance using telnet , ssh and https through ASDM to Cisco ASA Firewall.
To activate telnet access to ASA you need to have:
- username and password which will be used in authentication process,
- AAA lists definition that specifies the source of authentication, which can be through :
- Radius server
- TACACS+ server
- LOCAL ASA database
So to enable telnet using Local ASA Database:
- Define local username and password:
ASA#configure terminal
ASA(config)#username XXXX privilege 15 password YYYYY (Where XXXX = username and YYYY = your chosen password for that username)
- Define AAA lists for telnet:
ASA(config)#aaa authentication telnet console LOCAL
