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>

1 2 ... 27 28 29 30 31 32 33 34 35 36 37 ... 143 144
