Core Memory Dump—AXSM, AXSM-E, AXSM-32-T1E1-E, AXSM-XG
The core command applies to core memory dumps that can occur when a card is reset. (Whether a
specific reset type leads to a core dump is configurable.) You can copy zipped files to a workstation.
The core task has the following functional areas (further described in the Syntax Description sections):
• It displays:
– Whether core files from the processor card exist, the reset reason that triggered the core dump
as well as a list of all possible reset reasons, a time stamp, and so on
– Status of core dumps in progress
– The current configuration of various parameters
– A subset of core-related information on the CLI of a service module
• It lets you configure a wide variety of applicable functions.
• It can take an immediate action, such as aborting an active core dump or acquiring a snapshot of a
card's core memory.
Certain functions are complex enough to warrant a detailed description. These functions are noted in the
Syntax Description tables and have details in the Usage Guidelines section.
For any AXSM model, a core dump can occur during card boot-up after a reset. The processor compares
the reset reason to the core mask for that slot. For any match, core memory is written to a file in the root
directory of the C drive. The zipped file has the following format:
core_slotslot_num.zip, where slot_num is the number of the slot where the AXSM resides
The node logs messages for a service module core dump. The log shows when the core dump started,
finished, and aborted as well as any exceptions. To see these logs, use dsplog -mod CRDMP.
FTP files to a work station. You can send files to the Cisco TAC to be unzipped and debugged.
Note For a service module core hot-dump, run the command for only one slot at a time, otherwise it fails.

Syntax Description
core The core command without parameters indicates whether core dumps are
enabled for the current slot and that files reside on the C drive
?The core command with a question mark lists the optional parameters.
mask Enter core mask to display the following:
• A list of all possible reset reasons
• Whether the reset is enabled to trigger a core dump
• The associated hexadecimal value of each reason
The default mask is 0x262ee. To modify the mask, use mask hex-mask. See
also the section, “Usage Guidelines,” for the core mask details.
