When the memory allocation fails, an alert message is logged immediately. The alert message is
displayed at a frequency of 1 log per 5 minutes. The following example below displays an alert
message on the Management Module and the Interface Module.
The NULL value is returned to the calling routine. The calling routine will decide how to proceed
after the memory allocation fails.
NOTE
Notifications and traps are sent.
At any time, you can display the status of all recorded memory that is available on the Management
Module by entering the show memory command. The amount of available memory is displayed in
percentage values.The following example displays a show memory output on a Management
Module.
Switch fabric fault monitoring
With this feature, you can display information about the current status of links between the switch
fabric modules (SFM) and interface modules in a Brocade NetIron XMR or Brocade MLX series
chassis. This feature also provides log messages to the console when there is a change in the “UP”
or “DOWN” status of links to the SFM and when an individual fabric element (FE) cannot be
accessed by the management module. The device can also be configured to automatically shut
down an SFM when failure is detected. The following sections describe the capabilities of this
feature.
Displaying switch fabric information
You can display information about the current status of links between the SFMs and interface
modules in a Brocade NetIron XMR or Brocade MLX series chassis using the following command.
Each line represents a link between an SFM and an interface module (LP).
