Performance data collection
19
When there are more than 512 monitors in the system, monitors are saved to flash memory in the
following order:
• The EE monitors for each port (from 0 to MAX_PORT)
• The frame monitors for each port
EE monitors get preference saving to flash memory when the total number of monitors in a switch
exceeds 512. If the total number of monitors per port or switch exceeds the limit, then you will
receive an error message indicating the count has been exceeded and that some monitors have
been discarded.
1. Connect to the switch and log in as admin.
2. Type one of the following commands, depending on the action you want to perform:
• To save the current end-to-end and frame monitor configuration settings into nonvolatile
memory, use the perfCfgSave command:
switch:admin> perfcfgsave
This will overwrite previously saved Performance Monitoring
settings in FLASH. Do you want to continue? (yes, y, no, n): [no] y
Please wait ...
Performance monitoring configuration saved in FLASH.
• To restore a saved monitor configuration, use the perfCfgRestore command. For example,
to restore the original performance monitor configuration after making several changes:
switch:admin> perfcfgrestore
This will overwrite current Performance Monitoring settings in RAM. Do you
want to continue? (yes, y, no, n): [no] y
Please wait... Performance monitoring configuration restored from FLASH
ROM.
• To clear the previously saved performance monitoring configuration settings from
nonvolatile memory, use the perfCfgClear command:
switch:admin> perfcfgclear
This will clear Performance Monitoring settings in FLASH. The RAM settings
won’t change. Do you want to continue? (yes, y, no, n): [no] y
Please wait... Committing configuration...done.
Performance Monitoring configuration cleared from FLASH.
Performance data collection
Data collected through Advanced Performance Monitoring is deleted when the switch is rebooted.
Using the Brocade Network Advisor Enterprise Edition, you can store performance data persistently.
