Displaying MR2 management module memory usage

NOTE
Alarms are not generated for optic device insertion.
Switch fabric element
If a switch fabric element cannot be accessed, a major alarm is reported and logged.
Chassis fans, power supplies, and optics
If there is an indication that a single fan has failed, a major alarm is reported and logged on the tray. If an incompatible fan tray is detected,
a major alarm is reported and logged on the tray. When a fan tray is removed, any existing alarms are cleared and a major alarm is
reported and logged on the tray.
If a power supply is installed but powered down, a minor alarm is reported and logged. If a power supply is installed incorrectly, a major
alarm is reported and logged. If a power supply is not present, a major alarm is reported and logged.

Clearing the alarm history log

Use the clear alarm command to remove some or all of the current alarms. Once the alarm is cleared, it is removed from the current
alarm database and is no longer available even though the condition might still exist. The alarm is kept in the history log.
If you clear all alarms, a single entry is added to the history that indicates all alarms have been cleared.
To clear all alarms from the alarm logs, enter the following command:
Brocade# clear alarm all
For example, if you want to clear all alarms from the alarm logs on a specific optic in slot 9 of the interface module in slot 1, enter the
following command:
Brocade# clear alarm lp 1 optic 9

Disabling SNMP trap generation and logging

With the introduction of the alarm feature, you may want to disable some SNMP trap generation and logging to save space.
To disable SNMP fan change-trap generation, enter the following command:
Brocade(config)# no snmp-server enable traps fan-speed-change
To disable Syslog fan-speed-change logging, enter the following command:
Brocade(config)# no logging enable fan-speed-change
For additional information on SNMP traps and logging, refer to the
