About This Release
The VXSM GA Release 5.5.11 follows VXSM Release 5.5.10. The resolved caveats for VXSM Release
5.5.11 are listed in Table 5 on page 7.
The Voice Switch Service Module (VXSM) product is supported by the MGX 8880 Media Gateway and
the MGX 8850 Multiservice Switch. Refer to their respective release notes for platform and version level
support guidelines.

New Features in Release 5.5.11
Note
To verify that you have the latest version of Cisco IOS required to support the new features included in
this release, please check Cisco IOS availability status at Cisco.com.
The VXSM software release notes are supported by Cisco Voice Switch Services (VXSM) Configuration
Guide, Release 5.5 and Cisco Voice Switch Services (VXSM) Command Reference, Release 5.5, both of
which are available on cisco.com.
New Features in Release 5.5.11
Release 5.5.11 is a patch release that introduces the following two features:
•
DSP RAS and Memory Error Detection Mechanism
•
NSE Negotiation Based VXSM Up-speed
DSP RAS and Memory Error Detection Mechanism
Before Release 5.5.11, when a DSP core fails in an active VXSM, the standby VXSM takes over the
active card’s role. If the DSP core fails in a standby VXSM, then it reboots the standby VXSM. In such
a case, if the active VXSM also fails due to some reason, then there is a complete outage for 3 to 5
minutes. In case a DSP core fails in a standalone VXSM, then the failed DSP core is marked as a bad
core along with other sibling cores in the DSP chip. In this case, the existing calls on the affected DSP
chip are dropped and no new calls are allowed.
In Release 5.5.11, these issues are resolved by implementing the DSP RAS feature. When a DSP core
fails, VXSM brings the core back to in-service by re-downloading the DSP image on the entire DSP chip.
For active and standalone VXSMs, the existing calls on the chip are moved to other available cores
before the image re-download. VBD-fax calls are moved as voice calls on the new DSP core. T38 fax
calls will be dropped by VXSM during the call movement. Call movement will happen only if adequate
DSP channels are available to accommodate the affected calls; otherwise card will be reset in case of
redundant setup. For standalone VXSM, the card will continue to work with reduced capacity.
The memory error detection feature helps VXSM to detect the potential memory problems in DSP cores.
On receiving a memory corruption indication from the DSP, VXSM takes appropriate recovery actions.
This feature is supported only in TGW codec template in xGCP protocol. The following commands
are added to support this feature:
•
cnfDspRedownload
•
dspDspRedownload
NSE Negotiation Based VXSM Up-speed
From Release 5.5.11, in gateway controlled mode, VXSM upspeeds upon detecting the modem tones
only when NSE negotiation is successful in the Call Signaling. You can enable the feature by using the
cnfNseNegoUpspeed command. The command is supported only in xGCP mode.

Firmware Images
Firmware Images
For each VXSM card type (OC-3/STM-1, T1/E1, or T3), two firmware images are available, namely,
Non-CALEA and CALEA. When placing an order, the user must specify whether a Non-CALEA or
CALEA image is required.
Both CALEA and Non-CALEA images supports three Media Gateway Control protocols, namely,
H.248, MGCP, and TGCP. However, VXSM supports only one protocol at a time. The user must choose
between the H.248, MGCP, and TGCP protocols when the image is first loaded from the PXM using the
setrev command.
The CALEA image supports LI based on SII architecture for H.248, TGCP and MGCP protocols. The
PktCable CALEA is supported only with MGCP and TGCP protocols.
VXSM supports four different Codec templates; Tandem Gateway (TGW), Tandem Gateway 2, Fixed
Mobile Convergence (FMC), and Cable. The Cable template can be used only in conjunction with TGCP.
Upgrading from an Earlier VXSM Release
VXSM can be gracefully upgraded (configuration is preserved) from VXSM Release 5.4.21 or later.
Note
VXSM supports upgrade of non-CALEA to CALEA firmware. But upgrade from CALEA to
non-CALEA is not supported.
When loading or upgrading a boot or runtime image to a VXSM card, users must observe the following
caution:
Caution
Prior to upgrade, user should confirm that additional termtypes (other than the defaults) have not been
configured for VXSM in H.248.
Warning
Many of the commands involved in loading or upgrading boot and runtime images can take several
minutes to execute completely. If the user resets or otherwise disturbs the VXSM card during a
loading or upgrading process, the card can easily be damaged even to the extent that it must be
returned to the factory for repair.
In particular:
Do not reset VXSM or PXM cards manually or through commands such as resetcd or resetsys
Do not save all MGX configurations with commands such as saveallcnfs.
Do not toggle primary/secondary cards through commands such as switchredcd, delred
Do not change the name of software image before or during the upgrade
Do not change any configuration of active primary card during the upgrade
THE REAPPEARANCE OF THE COMMAND PROMPT AFTER A COMMAND IS ENTERED DOES NOT
INDICATE THAT THE IMAGE LOAD OR UPGRADE HAS BEEN COMPLETED.
After the execution of the burnboot, clrsmcnf, loadrev, or setrev commands, the user must execute
either a dspcds or dsprev command periodically to verify that the state of the VXSM card being loaded
or upgraded is either Active, Standby, or Failed.
ONLY WHEN THE CARD IS DISPLAYED TO BE IN ONE OF THESE STATES IS IT SAFE TO GO TO THE NEXT

VXSM Management Information Base
STEP.
If the upgrade procedure is interrupted for reasons outside the control of the user (for example, a
power outage), see “Interrupted Procedure Recovery” below for instructions.
Interrupted Procedure Recovery
In the event that a VXSM software upgrade procedure is interrupted (for example, power outage), and
both Primary and Secondary are stuck in 'Failed-U' state, perform the following procedure:
Step 1
Execute the abortrev command:
abortrev <PrimarySlot> <NewImageRevision>
Step 2
If the primary VXSM becomes “Failed/Active” (out of Failed-U/Active”), then execute the resetcd
command
resetcd <PrimarySlot>
Step 3
If the secondary VXSM becomes “Failed/Active” (out of Failed-U/Active”), then execute the resetcd
command:
resetcd <SecondarySlot>
Step 4
Both primary and secondary VXSM cards should now have their original SW image and original DB
VXSM Management Information Base
The VXSM Management Information Base (MIB) Version 5.5.11 is available to users with CCO
accounts who can access the MIB and VXSM software on-line at:
http://www.cisco.com/public/sw-center/index.shtml
Step 1
Log on to http://www.cisco.com/public/sw-center/index.shtml
Step 2
Locate the VXSM platform (either VXSM 8880 or VXSM 8850) and click the down arrow to expand the
“Select Release Level” drop down menu.
Step 3
Select the desired MIB release level (for example, Release 5500) to display a list of downloadable files.
Step 4
Click on the desired file (for example, mgx8850-fw-5500.tar).
Step 5
Read the license agreement and, if approved, click Accept.
Step 6
In the Software Download dialog box, click on Download: filename (where filename is the name of the
file selected for download). This step starts the download procedure.
Step 7
Follow the normal file download procedure for your computer.
Step 8
When the file has been downloaded, untar or unzip the downloaded file. The MIB file is included in the
downloaded file and is listed as a tar file (for example mgx8850rel5500mib.tar).
Step 9
Untar the MIB file to display its contents.
