Enabling and disabling packet logging for management and interface modules
5
Specify the stop keyword to stop packet logging.
NOTE
When finished gathering packet logging information for debugging purposes, Brocade recommends
disabling the generation of a packet log, which is CPU-intensive and can affect the performance of
the management module.
Displaying a packet log
You can use the following methods to display the contents of a packet log:
•
You can use the show packet-logging command, which is discussed in this section.
•
If you decided to write the log (pktlog.txt) to the management module flash memory, in addition
to using the show packet-logging command, you can access and view the log using flash
memory file management commands.
For example, to display a packet log for the interface module in chassis slot 1 that has been written
to the system’s memory, enter the following command at any CLI level:
Syntax: show packet-logging <slot-number> memory | flash pktlog.txt
For the <slot-number> parameter, you can specify 1 – 4 for BigIron RX-4, 1 – 8 for BigIron RX-8 or 1
– 16 for BigIron RX-16.
The memory | flash pktlog.txt keyword specifies that the packet log is written to the system’s
memory or to a file (pktlog.txt) written to the system’s flash memory.
