Usage Information Related Commands The Kernel core dump can be large and may take up to 5 to 30 minutes to upload. FTOS does not overwrite application core dumps so you should delete them as necessary to conserve space on the flash; if the flash is out of memory, the coredump is aborted. On the S-Series, if the FTP server is not reachable, the application coredump is aborted. FTOS completes the coredump process and wait until the upload is complete before rebooting the system. logging coredump server Designate a server to upload kernel core-dumps. tcpdump s z S6000 Enable a TCP dump for CPU bound traffic. Syntax tcpdump cp [capture-duration time | filter expression | packet-count value | snap-length value | write-to path] To disable the TCP dump, use no tcpdump Parameters capture-duration filter Enter the time for packet capturing. The timer begins as soon as the command is enabled. Range: 20-9000 seconds Specify the packet that will be dumped. If no filter is entered, all packets are dumped. Filter expressions usually consist of an id (name or number) preceded by one or more qualifiers. There are three different kinds of qualifier: type, direction, or protocol. Enclose the filter option with double quotes: "port 20." Range: 1-100 characters. Debugging and Diagnostics | 343
