exec-banner

Customizing the User Interface
exec Displays the banner after user authentication (if any) and before the
first prompt of a CLI session.
If you do not specify an option, the default behavior is to display the banner as
an MOTD.
The first character in the banner string must be repeated at the end of the string;
these characters delimit the banner. The CLI prompts you if you fail to repeat
the opening delimiter. All text following the second occurrence of the delimiter
is ignored without warning. The delimiter is case sensitive.
Banner text can span multiple lines. It is truncated after 1,024 characters.
Insert \n where you want the banner text to split and start a new line.
Alternatively, you can press Enter on the CLI when you want the text to break.
In the second case, you will be prompted for the remainder of the text after you
press Enter. To display a backslash as part of the message, it must be immediately
preceded by another backslash, like this: \\. Do not use a backslash as a delimiter
or end a line with a backslash.
To insert a ? character inside the text of a banner, you must enter Ctrl+v before
entering the ? character. Failure to do so may produce undesired results.

host1(config)#banner motd x This is an MOTD banner x
host1(config)#banner Y This is also an MOTD banner Y
host1(config)#banner "Quotes make good delimiters"
host1(config)#banner Xno space is required between the delimiter and the real

multiple line banner"
Use the default version to restore the default setting, in which the banner is
displayed on all lines.
You can configure MOTD or exec banners, but not login banners, for the CLI to
display on a per-line basis.
Use the no version to remove the banner.
See banner.
Use to display an exec banner on a particular line after user authentication (if
any) and before the first prompt of a CLI session.
Banners on the lines are enabled by default; the no version does not reenable
banners on the lines.
See "banner" on page 285 command description for more information about
configuring an exec banner.
