Using permit rules with the count option, you can track, on a per-flow basis, whether CPU-generated
packets were transmitted successfully. In addition, you can block certain CPU-generated and
soft-forwarded traffic.
This feature also allows you to configure an extended ACL that matches ICMP packets using the count
option, apply the ACL to an egress physical interface, and then ping through that interface to the
remote device.

Information
By default, the kernel core-dump is enable and stored in the flash directory:
• Storage Directory Name: flash:CORE_DUMP_DIR
— Kernel core-dump naming convention is: f10rpProcessorID.kcore.gz
— For example: F10rp1.kcore.gz
— Application core-dump naming convention is:
rpProcessorID _ApplicationName_timestamp.core.gz
For example: rp1_ospf_060307172608.core.gz
• Multiple core-dumps
— Application core-dumps are timestamp embedded and are not overwritten by default.
Manually delete the older core-dumps to allow more space on the flash.
— Kernel core-dumps are overwritten whenever there is a new core-dump.
Should a crash occur, the large crash kernel file may take more than ten minutes to upload and may
require more space on the flash than is available. The HA module is aware of a core-dump in process
and will wait until the upload is complete before rebooting the RPM.

Note: Only Layer 3 traffic goes through the ACL—i.e. BPDUs will not be captured.
Version 8.1.1.2 Introduced on E-Series ExaScale E600i
Version 8.1.1.0 Introduced on E-Series ExaScale E1200i
Note: Application core-dumps are also automatically uploaded to flash. If there is not enough
available space for the kernel core-dump on the flash, the kernel upload will terminate.
