Cisco MGX 8850 (PXM45) and MGX 8950 Software Configuration Guide
Release 3, Part Number 78-14788-01 Rev. C0, January 2004
Chapter 7 Switch Operating Procedures
Determining the Software Version Number from Filenames
Figure 7-1 Filename Format for Released Software
Filenames that include “_mgx” are for runtime PXM45 firmware, and filenames that include “_bt” are
for boot firmware. AXSM runtime firmware images do not have an image description after the version
number. When you first receive the switch from Cisco, there will be single versions of each file. If you
download updates to any files, there will be multiple versions of those files.
Figure 7-2 shows the information contained in filenames for prereleased firmware. If you are evaluating
nonreleased firmware, the filename format shows that the firmware is prereleased and indicates the
development level of the prerelease firmware.

Step 4
Translate the filenames to version numbers, and write the numbers down so you can set the revision
levels for the software.
Write the version number down in the format required by the revision management commands. The
following example shows the required format. If you are logged in as a user with SERVICE_GP access
privileges, you can display this example by entering any of the revision management commands without
parameters.
pop20one.7.PXM.a > runrev
ERR: Syntax: runrev <slot> <revision>
revision - revision number. E.g.,
2.0(1)
2.0(1.248)
2.0(0)B1 or 2.0(0)B2
2.0(0)A1 or 2.0(0)A2
2.0(0)I1 or 2.0(0)I2
2.0(0)D
The first example above, 2.0(1), is for released firmware version 2.0, maintenance release 1. The second
example, 2.0(1.248), is for patch 248 to version 2.0, maintenance release 1. The other examples are for
prerelease firmware. Prerelease firmware does not include patches; the maintenance release number is
increased for each software change.
