Banner
Banner configuration defines text messages displayed to users during device access on NX-OS, providing legal notices, usage warnings, and operational information before and after login. It supports both message-of-the-day (MOTD) banners shown at initial connection and exec banners displayed after successful authentication, enabling compliance with security policies requiring authorized-use notifications. Banners are essential for establishing legal standing regarding unauthorized access and communicating important operational information to network administrators.
