topic Passing router/switch IP address to the ACS from console port in Network Access Control https://community.cisco.com/t5/network-access-control/passing-router-switch-ip-address-to-the-acs-from-console-port/m-p/125282#M437687 <P>Is there a way to pass a IP address to the ACS when login on to a router or switch using the console port (line con 0)? The Caller-Id field on the ACS shows "ASYNC" when using the router/switch's console port.

However, as an alternative, you could use console port authorization, though it is generally accepted NOT to be an effective security measure. It can be easily by-passed using the break sequence to by pass the configuration. It can however be used to see as to who did what on the console port, which seems to be what you are trying. To enable command authorization, use the command aaa authorization console.</P><P></P></BODY></HTML> Mon, 15 Sep 2003 19:07:13 GMT https://community.cisco.com/t5/network-access-control/passing-router-switch-ip-address-to-the-acs-from-console-port/m-p/125283#M437721 drolemc 2003-09-15T19:07:13Z
