1590 Serviceability Tracing Packet Commands
• usb — Store the core dump on an un-mounted USB device
• none — Core dumps are disabled
Default Configuration
Full core dumps are disabled by default.
Command Modes
Global Configuration mode
User Guidelines
The TFTP server must be reachable over the out-of-band port. Configuring a
TFTP server reachable over a front panel port is unreliable during exception
processing. This implies that core dumps on the N2000 series switches must
use the USB target.
The USB device must be plugged in at the time of the core dump trap.
The configuration parameters are not validated when the command is
entered. The administrator can use the write core test command to validate
that the configured parameters are valid and the core dump is likely to
succeed.
The file name for the core file includes options as the time stamp or
hostname as per the configured parameters.
The TFTP core dump does not support TFTPD32 or Klever Pumpkin TFTP
servers.
Example
This example enables core dumps to a TFTP server 10.27.9.1 reachable over
the out-of-band port. The core file is written to the dumps directory and the
name includes the host name of the switch and the switch TOD.
console(config)#exception dump tftp-server 10.27.9.1 file-path dumps
console(config)#exception core-file Core hostname time-stamp
console(config)#exception protocol tftp
This example enables core dumps to a USB stick. The core file is written to
the top level directory and the name includes the host name of the switch and
the switch TOD.
console(config)#exception core-file Core hostname time-stamp
