Cisco Ccna (640-553) Security Training Using The Aaa Authentication (webvpn) Command In today article, I going to talk about the
aa authentication?command being used in webvpn context configuration mode. When network administrators (like you) use the aa
authentication?command in webvpn context configuration mode, they are configuring Authentication, Authorization, and Accounting
(AAA) authentication for Secure Socket Layer (SSL) Virtual Private Network (VPN) sessions. In other words, when a network
administrator uses the aa authentication?command in webvpn context configuration mode, he or she is most likely configuring either
an authentication list or server group for a SSL VPN context configuration. Below are the syntax and an example of the command:
Syntax: aaa authentication {domain name | list name} Example: Router(config)#aaa new-model Router(config)#aaa group server
radius myServer Router(config-sg-radius)#server 11.1.1.20 auth-port 1645 acct-port 1646 Router(config-sg-radius)#exit
Router(config)#aaa authentication login default local group myServer Router(config)#radius-server host 11.1.1.0 auth-port 1645 acct-
port 1646 Router(config)#webvpn context context1 Router(config-webvpn-context)#aaa authentication list myServer Router(config-
webvpn-context)#exit Notice, that when using the command; a network administrator can use either the omain?keyword or the ist?
keyword. When he or she uses the omain?keyword with the command (aaa authentication domain) he or she is configuring
authentication for a specific domain. And, when a network administrator uses the ist?keyword with the command (aaa authentication
list) he or she is configuring authentication for a specific list or server group. In the example above, the yServer?RADIUS server group
is being configured for authentication, for the SSL VPN context configuration named ontext1? If you need to remove the AAA
configuration from the SSL VPN context configuration, just type the word o?in front of the command like you see below: Router(config-
webvpn-context)#no aaa authentication list myServer Remember, in order for you to use the aa authentication?command in webvpn
context configuration mode; your router(s) must be running Cisco IOS 12.4(6)T or higher. I hope this article was very informative and
helped you quickly understand the usage of the aaa authentication (WebVPN) command. If you need to learn more; I suggest you visit
my website, were youl find the latest information regarding the Cisco CCNA (640-553) Security exam techniques. To your success,
