Guidelines and Limitations
This section includes the guidelines and limitations for this feature.
Context Mode Guidelines
Supported in single and multiple context mode.
Firewall Mode Guidelines
Supported in routed and transparent firewall mode.
Configuring a Login Banner
You can configure a message to display when a user connects to the ASA, before a user logs in, or before
a user enters privileged EXEC mode.
Restrictions
After a banner is added, Telnet or SSH sessions to ASA may close if:
• There is not enough system memory available to process the banner message(s).
• A TCP write error occurs when trying to display banner message(s).
Guidelines
• From a security perspective, it is important that your banner discourage unauthorized access. Do not
use the words “welcome” or “please,” as they appear to invite intruders in. The following banner
sets the correct tone for unauthorized access:
You have logged in to a secure device. If you are not authorized to access this
device, log out immediately or risk possible criminal consequences.
• See RFC 2196 for guidelines about banner messages.
Model License Requirement
All models Base License.
