The default behavior is a for log message to be sent only when the fan speed is actually changed,
which reduces the number of messages. A CLI option allows you to log all messages or have a
single log message sent when any temperature threshold is crossed.
Details about how to set temperature thresholds and default threshold values are described in the
“Configuring the cooling system” on page 331
Configuring temperature logging
The temp log-threshold command sets the temperature logging threshold to send a single message
whenever any of the thresholds are crossed.
Brocade(config) temp-log-threshold low
Syntax: temp-log-threshold [verbose | high | low | med | med-high]
• The verbose option generates logs whenever a temperature threshold is crossed. This is the
operational mode of previous versions of Multi-Service IronWare software and provides
backward compatibility.
• The high option generates logs only when the high threshold is crossed.
• The low option generates logs whenever any threshold (low, medium, medium-high or high) is
crossed.
• The med option generates logs only when the medium, medium-high, and high thresholds are
crossed.
• The med-high option generates logs only when the medium-high and high thresholds are
crossed. This is the default setting.
This output displays two instances of a module temperature exceeding the warning threshold.
Managing interface modules
Configuring interface module boot parameters
Ethernet interface modules contain independent copies of system software and boot after the
management module boots. By default, the following boot-related events occur:
• The router synchronizes, or prompts you to synchronize, the software image on the interface
modules with the software on the management module.
• Interface modules boot from a source specified by the management module (the default
source is a primary image in the flash memory on the interface module.)
You can make these changes:
• Disable the synchronization of images between the management module and all interface
modules. You can also initiate an immediate synchronization.
• Change the boot source of one or all interface modules.
Synchronizing the software image between management modules and interface
modules
An interface module can have primary and secondary images that reside in the flash memory.
