Hi,
We can configure the motd banner in Aruba gear, use the following commands.
(config) #banner motd #
Enter TEXT message [maximum of 4095 characters].
Each line in the banner message should not exceed 255 characters.
End with the character '#'.
( Type your banner here )
Welcome to Aruba #
(To preview your banner )
(config) #show banner
Welcome to Aruba
Hope answered your question :)
Cheers,
Venu Puduchery
