Displaying the boot image version running on the device
To determine the boot image running on a device, enter the show flash command at any level of the
CLI. The following shows an example output.
device#show flash
Active Management Module (Slot 9):
Compressed Pri Code size = 3613675, Version 03.1.00aT3e3 (sxr03100a.bin)
Compressed Sec Code size = 2250218, Version 03.1.00aT3e1 (sxs03100a.bin)
Compressed BootROM Code size = 524288, Version 03.0.01T3e5
Code Flash Free Space = 9699328
Standby Management Module (Slot 10):
Compressed Pri Code size = 3613675, Version 03.1.00aT3e3 (sxr03100a.bin)
Compressed Sec Code size = 2250218, Version 03.1.00aT3e1 (sxs03100a.bin)
Compressed BootROM Code size = 524288, Version 03.0.01T3e5
Code Flash Free Space = 524288
The boot code version is shown in bold type.
Displaying the image versions installed in flash memory
Enter the show flash command to display the boot and flash images installed on the device. An
example of the command output is shown in Displaying the boot image version running on the device
on page 92:
• The "Compressed Pri Code size" line lists the flash code version installed in the primary flash area.
• The "Compressed Sec Code size" line lists the flash code version installed in the secondary flash
area.
• The "Boot Monitor Image size" line lists the boot code version installed in flash memory. The device
does not have separate primary and secondary flash areas for the boot image. The flash memory
module contains only one boot image.
NOTE
To minimize the boot-monitor image size on FastIron devices, the ping and tftp operations performed
in the boot-monitor mode are restricted to copper ports on the FastIron Chassis management modules
and to the out-of-band management port on the FastIron stackable switches. The other copper or fiber
ports on these devices do not have the ability to ping or tftp from the boot-monitor mode.
Flash image verification
The Flash Image Verification feature allows you to verify boot images based on hash codes, and to
generate hash codes where needed. This feature lets you select from three data integrity verification
algorithms:
• MD5 - Message Digest algorithm (RFC 1321)
• SHA1 - US Secure Hash Algorithm (RFC 3174)
• CRC - Cyclic Redundancy Checksum algorithm
Flash image CLI commands
Use the following command syntax to verify the flash image:
Syntax: verify md5 | sha1 | crc32 ASCII string|primary|secondary[hash code]
• md5 - Generates a 16-byte hash code
• sha1 - Generates a 20-byte hash code
