Managing the interface modules
5
The all | <slot-number> parameter specifies that the automatic boot applies to all interface
modules in the BigIron RX Series chassis or to an interface module in the specified chassis slot
number only. You can specify 1 – 4 for BigIron RX-4, 1 – 8 for BigIron RX-8 or 1 – 16 for BigIron
RX-16.
Configuring an automatic interactive boot
For example, to configure an automatic interactive boot for all interface modules, enter the
following command at the global CONFIG level of the CLI:
BigIron RX(config)# lp boot system interactive all
Syntax: lp boot system interactive all | <slot-number>
The all | <slot-number> parameter specifies that the automatic boot applies to all interface
modules in the BigIron RX Series chassis or to an interface module in the specified chassis slot
number only. You can specify 1 – 4 for BigIron RX-4, 1 – 8 for BigIron RX-8 or 1 – 16 for BigIron
RX-16.
After you enter this command, the system enters the interface module’s monitor mode. For
example, to boot from the primary IronWare image in the interface module’s flash memory, enter
the following command at the monitor prompt:
LP MONITOR> boot system flash primary
Changing priority of chassis slots for interface modules
You can prioritize the BigIron RX Series chassis slots in which the interface modules are installed.
The priority range is 1 – 8, where 1 is the lowest priority and 8 is the highest priority. You can set
one, some, or all chassis slots to the same priority or each chassis slot to a different priority. If you
assign the same priority to all slots, the lowest-number slot has the highest priority, while the
highest-numbered slot has the lowest priority.
By default, the priority of all chassis slots is 1, which is the lowest priority. If the supply of power to
the chassis falls below a minimum threshold, the chassis slots will likely lose power because of
their low priority. In this scenario for an BigIron RX-8 chassis, slot 8 will lose power first, then slot 7,
slot 6, and so on until slot 1 loses power.
For example, to set the priority of chassis slot 1 to the highest priority (8), enter the following
command:
BigIron RX(config)# lp-slot-priority 1 8
Syntax: lp-slot-priority <slot-number> <priority>
The <slot-number> parameter indicates that the chassis slot number for which you are changing
the priority. You can specify slots 1 – 4 for BigIron RX-4, 1 – 8 for BigIron RX-8 or 1 – 16 for BigIron
RX-16.
The <priority> parameter indicates that the priority of the chassis slot if the chassis loses power.
You can specify a value of 1 – 8, where 1 is the lowest priority and 8 is the highest priority. You can
set one, some, or all chassis slots to the same priority or each chassis slot to a different priority.
