Release Information

Statement introduced before Junos OS Release 7.4.

Description

Configure the medium used for storing memory snapshots of system failure. When you specify the storage and an operating system fails, the operating system writes a snapshot of the state of the router when it failed to the storage medium. When the operating system is rebooted, the storage device is checked for a snapshot. If found, the snapshot of memory is written to the /var/crash directory on the router and can be examined by Juniper Networks customer support to help determine the cause of failure.

If the swap partition on the device medium is not large enough for the system memory snapshot, the snapshot is not successfully written to the directory. Use the request system snapshot command to specify the swap partition.

Options

compact-flash—The primary CompactFlash card.

removable-compact-flash—The CompactFlash card on the front of the router as the system software failure memory snapshot device.

usb—The device attached to the universal serial bus (USB) port.
