logging coredump server Configure the switch to move (upload) a core dump for an application or kernel crash to an external FTP server. C9000 Series Syntax Parameters logging coredump server {ipv4-address | ipv6-address} username name password [type] password {ipv4-address | ipv6-address} name type password Enter the server IPv4 address (A.B.C.D) or IPv6 address (X:X:X:X::X). Enter a username to access the target server. Enter the password type: ● Enter 0 to enter an unencrypted password. ● Enter 7 to enter a password that has already been encrypted using a Type 7 hashing algorithm. Enter a password to access the target server. Defaults Core dumps for kernal and application crashes are stored in the local flash of the Control Processor CPU. Command Modes CONFIGURATION Command History This guide is platform-specific. For command information about other platforms, refer to the relevant Dell Networking OS Command Line Reference Guide. The following is a list of the Dell Networking OS version history for this command. Version Description 9.9(0.0) 9.2(1.0) 9.0(1.0) Introduced on the C9010. Introduced on the Z9500. Introduced on the S5000. Usage Information The switch supports full core dumps for kernel crashes. The kernel core dump applies to all CPUs and is not enabled by default. To enable full kernel core dumps, enter the logging coredump command in global configuration mode. The kernel core dump is copied to the Control Processor (CP) core-dump directory: flash://CORE_DUMP_DIR/f10_cpu_timestamp.kcore.gz Where cpu specifies a CPU and is one of the following values: cp (Control Processor), cp (Route Processor), lp0 (line-card processor 0), lp1 (line-card processor 1), or lp2 (line-card processor 2); timestamp is a text string in the format: yyyyddmmhhmmss (YearDayMonthHourMinuteSecond). Because flash space may be limited, using the logging coredump server command ensures your crash (application and kernel) files are uploaded successfully and completely to a server. Only a single core-dump server can be configured. Configuration of a new core dump server over-writes any previously configured server. NOTE: You must disable logging coredump (no logging coredump command ) before you configure a new server destination for core dumps. When you enter the logging coredump server command, you are required to enter a password. Use the password of the FTP server where the core files are to be copied. The password can be up to 15 characters; special characters are allowed. After you enter the password, an FTP URL is created with the credentials in the operating system. The CLI monitors core dumps in the unit. On the switch, when you enable core dumps of application and kernel crashes to be uploaded to an FTP server, only core dumps from the Control Processor are uploaded to the server. Core-dump files from the Route Processor and line-card CPUs are moved to flash memory on the Control Processor CPU and can be accessed by performing an FTP to the Control Processor core-dump directory: flash:// CORE_DUMP_DIR/f10_cpu_timestamp.kcore.gz Control and Monitoring 87
