1. Determine the versions of the software images currently installed and running on the router.
Use the procedures described in “Displaying flash memory and version information” on
page 124.

Command change
Beginning in version 02.5.00 and later of the Multi-Service IronWare software, the copy tftp image
command has been changed to enable the user to upgrade the boot, monitor, and MBRIDGE only
when needed.
NOTE
The changes to the copy tftp image command will appear when upgrading to any version after
02.5.00.
New default behavior
• Without any options selected, the unified image will copy the MP monitor, LP monitor, and the
MP and LP applications to the primary location.
• The option to exclude copying the MBRIDGE and exclude copying the boot from the unified
image was removed.
• Unified images will now include MBRIDGE for BigIron RX-16/8/4 (mbridge.xsvf) .
New options added
New options have been added to the copy tftp image command to enable the user to upgrade the
boot, monitor, and MBRIDGE only when needed.
Syntax: copy tftp image <TFTP-server-ip-addr> <image-name> [lp-boot | lp-sec | mp-boot |
mp-sec | mbridge]
