Displaying Modem Code Versions
Use the show modem mapping command to list the versions of modem code running on the modem
modules, residing in system Flash memory, and bundled with Cisco IOS software. This will help you
decide if you need to change the version running on the modems.

Description
Modem code on the MICA modems resides in and runs out of modem RAM.
Cisco IOS software transfers a version of modem code to modem RAM on
each reboot and reload.
System Flash memory can contain several versions of modem code: a version
bundled with Cisco IOS software and multiple versions that resulted from
previous copy tftp flash commands.
This command transfers the version of modem code bundled with Cisco IOS
software to the modem RAM and maps that version to the modem modules
specified by the modem range.
To view a list of microcode filenames, use the command dir system:/ucode.
This command does not affect any existing versions of modem code that reside
in system Flash memory.
After one copy system:/ucode/filename modem command, future Cisco IOS
upgrades will potentially result in the downloading of new Cisco IOS bundled
firmware to the modems. (If the new Cisco IOS image contains the same
modem code as the old one, no new code will be downloaded to the modems.)
Places a copy of the modem code in system Flash memory.
This command transfers the version of modem code in system Flash memory
to the modem RAM and maps that version to the modem modules specified by
the modem range.
The copy commands map a specific version of modem code to a group of
modem slots/ports. The copy system:/ucode/filename modem command (or,
for Cisco IOS releases earlier than 11.3AA or 12.0, the copy ios-bundled
modem command) maps the slots/ports to the bundled version, and the
copy flash modem command maps the slots/ports to the system Flash version.
Cisco IOS software uses the mapping to determine which version of modem
code should be downloaded to the modems. If Cisco IOS software finds no
mapping or invalid mapping, it downloads the bundled version.
Although modem ranges are specified on as slot/port, the modem code is
downloaded on a per module basis.
The show modem mapping command lists all versions of modem code
running on the modem modules, residing in system Flash, and bundled with
Cisco IOS software. This will help you decide if you need to update your
1
modem code files.
