Configuring the device as an SNTP server
2
The DST feature is automatic, but to trigger the device to the correct time, the device must be
configured to the US time zone, not the GMT offset. To configure your device to use the US time
zone, enter the clock timezone us pacific command.
Brocade(config)# clock timezone us pacific
Syntax: [no] clock timezone us <timezone-type>
Enter pacific, eastern, central, or mountain for <timezone-type>.
This command must be configured on every device that follows the US DST.
To verify the change, run a show clock command.
Brocade# show clock
Limiting broadcast, multicast, and unknown unicast traffic
Brocade devices can forward all flooded traffic at wire speed within a VLAN. However, some
third-party networking devices cannot handle high rates of broadcast, multicast, or
unknown-unicast traffic. If high rates of traffic are being received by the Brocade device on a given
port of that VLAN, you can limit the number of broadcast, multicast, or unknown-unicast packets
received each second on that port. For more information about limiting broadcast, multicast, and
unknown unicast traffic, refer to the Brocade ICX 6650 Switch Security Configuration Guide.
CLI banner configuration
Brocade ICX 6650 devices 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 terminal when he or she
establishes a Telnet CLI session. For example, to display the message “Welcome to Brocade ICX
6650!” when a Telnet CLI session is established.
Brocade(config)# banner motd $ (Press Return)
Enter TEXT message, End with the character '$'.
Welcome to Brocade ICX 6650! $
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 4000 characters long, which can consist of multiple lines.
Syntax: [no] banner motd <delimiting-character>
To remove the banner, enter the no banner motd command.
