L2 Operation
007-4857-002 93
To target individual blades in an IRU use the following syntax:
olympic-101-L2> 1.11 b1 power down
Executing the above command will power down the blade in blade slot 1 of the IRU in rack 001
U position 11.
Default Destination
When the L2 starts, the default destination is set to all racks and all slots. You can determine the
default destination by using the destination command:
L2> destination
all racks, all slots
L2>
The following command sets the destinations to rack 2 and 3, all slots:
L2> r 2,3 destination
2 default destination(s) set
L2>
The following example shows what IRUs are found in the default destination. If you enter a
command not understood by the L2, the command is sent to these IRUs.
Note: In the current implementation, if you add an IRU to either rack 2 or 3, it would not be
automatically included in the default destination. You would need to reset the default destination.
L2> destination
001c01 (127.0.0.1:0:2)
001c01 (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 IRUs in racks 2, 3, 4, and 7:
