Broadcasting Messages to all Users
Message broadcasting is an important feature to forewarn all CLI users that some major event is about
to take place, such as bringing down a network for administration. A broadcast message is sent to every
active CLI session on the InfiniBand system chassis.
Enclose multi-word messages within double-quotes. Single-word messages do not require
double-quotes. Only the unrestricted user may broadcast messages.
Syntax
The message identifies the sender, followed by the message text.
For example, if you send this:
Everyone, including the user who sent the message, receives this:
Sending Messages to Individual Users
The
write
command is used to send a message to a single user. Check that the user is logged in before
attempting to write to their terminal.
1. Enter the
show user
user_name command to verify the user is logged in.
2. Enter the write command to message the individual.
Setting the System Clock
Maintaining accurate time is important for statistics and auditing. The switch chassis provides an
on-board system clock to save the time settings across reboots. Time is maintained in one of two ways:
• An on-board system clock
• External NTP servers
