AAA authentication banner

I configured my 3750 switches to use the "aaa authentication banner" command and I setup a custom banner. If the ACS server is online I don't see this custom banner. If I disconnect the Cisco ACS server from the network forcing local authentication, the banner is displayed. The "aaa authentication fail-message" works perfectly all the time. Why is the aaa authentication banner not being displayed?

Thanks for the help.

Re: AAA authentication banner

Look like your platform does not support aaa

authentication banner:

The following platforms support login banners for AAA authentication:

•Cisco 1003, Cisco 1004, Cisco 1005

•Cisco 2500 series

•Cisco 3000/IGS

•Cisco 4000 series (Cisco 4000, 4000-M, 4500, 4500-M, 4700, 4700-M)

•Cisco AS5200 series

•Cisco AS5300

•Cisco 7000 series

•Cisco 7200 series

•Cisco 7500 series

That being said, it is not working on the

Cisco VXR7204 either.

Re: AAA authentication banner

Hi,

That link is out of date as it refers to IOS version 11.3 - the feature really is supported (which can be checked using the feature navigator).

The original question refers to the feature not working as expected - not whether it's supported or not. If we check the command reference we can see a note as follows:

The AAA authentication banner message is not displayed if TACACS+ is the first method in the method list.

I suspect this might be why it isn't working as expected. If so, a message of the day banner might be a better solution. (Using the banner motd command.)

HTH

Thanks for the info. I am glad I finally understand why this is not working that way I thought it would.
