About Release 22.214.171.124
Version .201 of Release 5.3.10 is a patch release that does not introduce new features. For information about resolved anomalies in Version .201, see Table 5.
The VXSM Release 126.96.36.199 follows VXSM Release 5.3.00.200.
For each VXSM card type (OC-3, T1/E1, or T3), two firmware images are available, namely, Non-CALEA and CALEA. At order time, the user must specify whether a Non-CALEA or CALEA image is required.
The Non-CALEA image supports three Media Gateway Call Control (MGC) protocols, namely, H.248, MGCP, and TGCP. However, the image supports only one protocol at a time. The user must choose between the H.248, MGCP, and TGCP versions when the image is first loaded from the PXM using the setrev command.
The CALEA image supports TGCP and MGCP only. The protocol must be explicitly selected when the image is loaded from the PXM using the setrev command.
Upgrading from an Earlier VXSM Release
VXSM can be gracefully upgraded (configuration is preserved) from any VXSM Release 5.2.x.x (or later) so long as the original and the upgraded images are of the same version (for example Non-CALEA, TGCP to Non-CALEA, TGCP). When loading or upgrading a boot or runtime image to a VXSM card, users must observe the following caution.
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.
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 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:
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 5.3 is available by request through your Cisco VXSM product marketing representative.
Alternatively, users with CCO accounts can access the MIB and VXSM software on-line at:
The procedure is:
Step 1 Log on to http://www.cisco.com/kobayashi/sw-center/sw-wan.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 5300) to display a list of downloadable files.
Step 4 Click on the desired file (for example, mgx8850-fw-5300.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 mgx8850rel5300mib.tar).
Step 9 Untar the MIB file to display its contents.

Locate the serial number label on your product and record the information before placing a service call.
Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:
For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
