IPS Module Core Dumps

IPS core dumps are different from the system's kernel core dumps for other modules. When the IPS
module's operating system (OS) unexpectedly resets, it is useful to obtain a copy of the memory image
(called a IPS core dump) to identify the cause of the reset. Under that condition, the IPS module sends
the core dump to the supervisor module for storage. Cisco MDS switches have two levels of IPS core
dumps:
•
•
To configure IPS core dumps on the IPS module, follow these steps:
Command
Step 1
switch# config terminal
switch(config)#
Step 2
switch(config)# ips core dump full
ips core dump full' successfully set for
module 9
switch(config)# no ips core dump full
ips core dump partial' successfully set for
module 9

IPS-4 and IPS-8 modules (refer to the Cisco MDS 9200 Series Hardware Installation Guide or the
Cisco MDS 9500 Series Hardware Installation Guide for more information)
MPS-14/2 module (refer to the Cisco MDS 9200 Series Hardware Installation Guide or the Cisco
MDS 9500 Series Hardware Installation Guide for more information).
In both the MPS-14/2 module and the Cisco MDS 9216i integrated supervisor module, the port
numbering differs for the Fibre Channel ports and the Gigabit Ethernet ports. The Fibre Channel
ports are numbered from 1 through 14 and the Gigabit Ethernet ports are numbered 1 and 2.
Cisco MDS 9216i Switch (refer to the Cisco MDS 9200 Series Hardware Installation Guide).
Partial core dumps (default)—Each partial core dump consists of four parts (four files). All four files
are saved in the active supervisor module.
Use the show cores command to list these files.
Full core dumps—Each full core dump consists of 75 parts (75 files). The IPS core dumps for the
MPS-14/2 module and the Cisco MDS 9216i Switch only contains 38 parts. This dump cannot be
saved on the supervisor module because of its large space requirement. They are copied directly to
an external TFTP server.
Use the system cores tftp: command to configure an external TFTP server to copy the IPS core
dump (and other core dumps).

Purpose
Enters configuration mode.
Configures a dump of the full core generation for
all IPS modules in the switch.
Configures a dump of the partial core (default)
generation for the IPS module in slot 9.
