Switch Management Commands 2149
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-
ON/N2200-ON 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
exception protocol
Use the exception protocol command as directed by Dell EMC Networking
support to enable full core dumps. Use the no form of the command to
disable full core dumps.
