2: Using the L1 and L2 Controllers
The following example shows what bricks are found in the default destination. If you
type a command not understood by the L2, the command is sent to these bricks.
Note: In the current implementation, adding a brick to either rack 2 or 3 would not
automatically include it in the default destination. You would need to reset the default
destination.
L2> destination
002c01 (127.0.0.1:0:2)
003c01 (127.0.0.1:0:0)
L2>
The following command resets the default destination to all racks and all slots:
L2> destination reset
default destination reset to all racks and slots
L2>
Current Destination
The current destination is a range of racks and slots for a given command. For example,
the following command sends the command <L1 command> to all bricks in racks 2, 3, 4,
and 7:
L2> r 2-4,7 <L1 command>
This is a one-time destination.
Command Interpretation
Some L2 commands are the same as the L1 commands. In many cases, this is intentional
because the L2 provides sequencing that is necessary for a command to function
correctly.
When L1 and L2 commands are similar, you can assure that an L1 command is entered
for the bricks in the current destination by preceding <L1 command> with the L1
command (this is a one-time destination), as follows:
L2> r 2-4,7 l1 <L1 command>
