User Guidelines
Crash dump retrieval via FTP or TFTP occurs after the system has crashed.
During this time, the switch is not available for normal operation.
If no DHCP server is available for assignment of addresses to switches, the
exception dump stack-ip-address protocol static add command should be
used once for each member of the stack. It is recommended that these
addresses be unique in the network. The stack master will distribute the
addresses to the stack members for use on the out-of-band port only during
crash dump transfer. In addition, for the purposes of transferring the core file
to the server, a unique MAC address is assigned to the stack unit.
As crash dump retrieval is not reliable on the front panel ports, the TFTP and
FTP parameters are not available on the N1100-ON/N1500/N2000/N2100
series switches. Use the USB crash dump capability instead.
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 flash drive. 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
