Limiting unknown unicasts
To globally limit the number of unknown unicast packets a Brocade device forwards to 110,000 per
second, enter the following command at the global CONFIG level of the CLI.
Brocade(config)# unknown-unicast limit 110000
Brocade(config)# write memory
Syntax: [no] unknown-unicast limit number
NOTE
Only the unknown-unicast limit is configured on the global level, but the value you enter applies to
each interface module (slot) installed on the device.
Configuring CLI banners
The Brocade device can be configured to display a greeting message on users’ terminals when they
enter the Privileged EXEC CLI level or access the device through Telnet. In addition, a Brocade
device can display a message on the Console when an incoming Telnet CLI session is detected.
Setting a message of the day banner
You can configure the Brocade device to display a message on a user’s terminal when he or she
establishes a Telnet CLI session. For example, to display the message “Welcome to Brocade!” when
a Telnet CLI session is established, enter the following.
Brocade(config)# banner motd $(Press Return)
Enter TEXT message, End with the character '$'.
Welcome to Brocade! $
A delimiting character is established on the first line of the banner motd command. You begin and
end the message with this delimiting character. The delimiting character can be any character
except “(double-quotation mark) and cannot appear in the banner text. In this example, the
delimiting character is $(dollar sign). The text in between the dollar signs is the contents of the
banner. The banner text can be up to 2047 characters long and can consist of multiple lines. To
remove the banner, enter the no banner motd command.
Syntax: [no] banner delimiting-character | [motd delimiting-character]
NOTE
The banner delimiting-character command is equivalent to the banner motd delimiting-character
command.
NOTE
The size of the MOTD banner will be restricted (truncated) to 1850 characters when using an SSH
client.
