Synopsis

parityCheck [ mode ]

Availability admin

Description This command enables DRAM parity checking. The mode is saved in flash

memory and stays in that mode until the next execution of parityCheck.

The mode becomes active as soon as this command is executed. It does not

require a reboot to take effect.

The DRAM parity checking, when enabled, causes ramTest to perform

several additional tests of the parity memory. It also enables the parity

checking hardware to verify proper parity on all DRAM read operations.

DRAM parity checking is available only on specific switch models. If the

current switch does not support parity checking, an error is displayed.

a 0 to disable it. The default (if no operand is specified)
