Limitations and Restrictions
The VISM 3.2 software is applicable to VISM and VISM-PR. The following limitations and restrictions are valid for software Release 3.2 for VISM/VISM-PR:
•For the lossless codec, use the cnfcodecjtrdelay command to configure the fixed jitter-delay argument to 20 msec.
•In a PNNI network, upspeeding SVC fax or modem calls requires an increase in bandwidth between the voice codec and the vbd codec. For fax calls to go through, disable policing on the service modules (excluding VISM/VISM-PR).
•Switched AAL2 PVC mode is not recommended as this mode requires a meshed PVC network topology, which does not scale.
•The following commands are not supported:
–cnfmaxconfnum
–dspconferences
–dspmaxconfnum
•GR-303 is not supported for the LAPD commands.
•In AAL2 SVC mode, all active calls on VISMs are dropped upon PXM hard and soft switchover.
•For a list of open issues and mitigations in VISM Release 3.2, see "Open Caveats in Release 3.2" section.

Prerequisites
To ensure that the VISM/VISM-PR configuration is preserved throughout the upgrade procedure, you must complete the prerequisites listed in this section.
Before starting the graceful upgrade procedure, complete the following prerequisites:
•Configure your MGX 8000 Series shelf with at least two VISM cards in a redundant configuration.
For more information on adding redundancy, refer to the add redundancy, addred, command in the Cisco MGX 8250, Cisco MGX 8230, and Cisco MGX 8850 PXM1-based Command Reference documentation and the Cisco MGX 8830 and Cisco MGX 8850 PXM1E/ PXM45-based Command Reference documentation.
•Ensure that the VISM cards are running at least Release 2.1, and the VISM-PR cards are running at least Release 3.0.
•Download software Release 3.2 for VISM/VISM-PR to the MGX 8000 Series shelf.
•If you are using the CALEA feature, ensure that you have the version of VISM/VISM-PR software that supports CALEA.
VISM/VISM-PR Upgrades with PXM1
This section describes the procedures for upgrading VISM/VISM-PR software when the VISM/VISM-PR is used with a PXM1 card.
Download VISM/VISM-PR Boot Code and Firmware to PXM1
To download the VISM/VISM-PR boot code and firmware to the PXM1 card, use TFTP.
Step 1 Log in to your TFTP server.
Step 2 Download the boot code and firmware images from the Cisco website.
Step 3 Download the selected revision of service module boot code into the service module.
a. tftp <node_name or IP address>
b. bin
c. put <backup boot> POPEYE@SM_1_0.BT
d. quit
Step 4 Download the selected firmware file.
To upgrade all VISM cards, proceed to Step 4 c. To upgrade an individual VISM card, proceed to Step 4 d.
a. tftp <node_name or IP address>
b. bin
c. put <FW file> POPEYE@SM_1_0.FW
quit
d. put <FW file> POPEYE@SM_1_<slot number of card to upgrade>.FW
quit
Note Do not enter two put commands in the same TFTP session.
Step 5 Proceed to the "Upgrade VISM/VISM-PR Firmware with PXM1 Card" section to install the download.
Upgrade Boot Code with PXM1 Cards
Complete the following steps to upgrade the new backup boot code when you are using PXM1 cards in in a Cisco MGX 8230, Cisco MGX 8250, and Cisco MGX 8850 chassis:
Note This procedure re-programs the VISM/VISM-PR boot code for previous VISM/VISM-PR cards using the VISM/VISM-PR runtime image version 1.0 to 2.0.
Step 1 Log in to the active PXM1 card (slot 7 or 8 for Cisco MGX 8250 and Cisco MGX 8850 chassis; slot 1 or 2 for Cisco MGX 8230 and Cisco MGX 8830 chassis).
Note VISM/VISM-PR must be in the active state in order to update the VISM/VISM-PR boot code.
Step 2 Execute the PXM1 install command.
nodename.1.27.VISM8.a > install [bt] [sm <slot>] <version>
Caution Do not touch the VISM/VISM-PR card until the status comes back ('Sent xxx bytes in yyy seconds'). Failure to follow this recommendation corrupts the boot code, which cannot be recovered.
When the boot code is being written to PROM, you see comments displayed at the VISM/VISM-PR prompt. This behavior is normal and expected.
Step 3 Type the version command to verify the correct boot code.
Note Step 3 is optional.
Upgrade VISM/VISM-PR Firmware with PXM1 Card
Software Release 3.2 is for VISM and VISM-PR cards. Ensure that the VISM and VISM-PR cards have the minimum boot code version of VI8_BT_3.2.00.
The following versions of VISM software Release 3.2 are available:
•003.002.000.000—without CALEA
•003.052.000.000—with CALEA
In this procedure the following conditions apply:
•If two VISM or VISM-PR cards are part of a redundancy group, initially the primary card is in the active state, and the secondary card is in the standby state.
•Old-rev refers to the firmware, Release 3.1(3) and prior.
•New-rev refers to the firmware after the upgrade, Release 3.2.
Perform the firmware upgrade on the VISM or VISM-PR cards. Do not remove the VISM cards and replace them with VISM-PR cards at this time.
Step 1 Log in to the active PXM1 card (slot 7 or 8 for Cisco MGX 8250 and Cisco MGX 8850 chassis; slot 1 or 2 for Cisco MGX 8230 and Cisco MGX 8830 chassis).
Step 2 Save the existing configuration as a contingency plan by entering the savesmcnf command:
nodename.1.8.PXM.a > savesmcnf <SM slot#>
This command saves the existing configuration in the C:CNF directory. This file can be used during the downgrade procedure.
Step 3 To obtain the correct version of VISM/VISM-PR firmware, enter the dspfwrevs command.
nodename.1.8.PXM.a > dspfwrevs
Card Type Date Time Size Version File Name

Step 4 Execute the PXM install command.
nodename.1.8.PXM.a > install sm <SM slot#> <new-rev>
Replace <SM slot#> with the slot number of the primary VISM or VISM-PR card.
Replace <new-rev > with the version of the new firmware (for example, 003.002.000.000).
Caution Ensure that you perform Step 4. If you do not perform Step 4, the boot code is corrupted and not recoverable.
This command causes the secondary VISM or VISM-PR card to reset and come up in the standby state, running the new-rev firmware. The primary VISM or VISM-PR card is unaffected by this command.
Step 5 Execute the PXM newrev command.
nodename.1.8.PXM.a > newrev sm <SM slot#> <new-rev>
Replace <SM slot#> with the slot number of the primary VISM or VISM-PR card.
Replace <new-rev> with the version of the new firmware.
This command causes the primary VISM or VISM-PR card to reset. The secondary VISM or VISM-PR card becomes active and is running the new-rev firmware.
Step 6 Execute the PXM commit command.
nodename.1.8.PXM.a > commit sm <SM slot#> <new-rev>
Replace <SM slot#> with the slot number of the primary VISM or VISM-PR card.
Replace <new-rev> with the version of the new firmware.
The two VISM or VISM-PR cards are now back to their original condition except that both cards are now running the new-rev firmware.
Step 7 Log in to the active VISM or VISM-PR card and use the display commands (for example, dspendpts, dspcasvar, and so forth) to confirm that the configuration has been preserved through the upgrade process.
Note For more than one primary VISM or VISM-PR card in a redundancy group, ensure that the secondary card is in the standby state and repeat Step 5 and Step 6 for each VISM/VISM-PR card in the redundancy group.
Step 8 Perform the following verifications:
•Make minor modifications to the configuration.
•Check that the changes have been executed correctly.
•Change the configuration back again.
Note If the VISM or VISM-PR card is not part of a redundancy group, complete Step 1 to Step 4.
VISM-PR Upgrades with PXM1E and PXM45
This section describes the procedures for upgrading VISM-PR software when the VISM-PR is used with a PXM1E or PXM45 card.
Download VISM-PR Boot Code and Firmware to PXM1E and PXM45
To download the VISM-PR boot code and firmware to the PXM1E or PXM45 card, use FTP.
Step 1 Access the image on the Cisco Web site.
Step 2 To download the image, enter the ftp command.
ftp node-ip
where node-ip is the IP address of the node to which you want to download the image.
Step 3 Enter your user name and password.
Step 4 Enter bin.
Step 5 Access the appropriate directory.
cd C:FW
Step 6 Download the image to your C:FW directory.
a. To download one file at a time, use the put image-version command.
b. To download multiple files at the same time, use the mput <image-version> <image-version> command.
where image-version is the downloaded image from Step 1.
Step 7 To exit the download procedure, enter bye.
Upgrade Boot Code with PXM1E and PXM45 Cards
Complete the following steps to upgrade the new backup boot code when you are using PXM1E or PXM45 cards in your MGX 8000 Series chassis:
Step 1 Complete the steps in the Download VISM-PR Boot Code and Firmware to PXM1E and PXM45.
Step 2 Log in to the PXM1E or PXM45 card.
Step 3 To upgrade the VISM-PR boot, enter the burnboot command.
nodename.1.7.PXM.a > burnboot <slot> <revision>
Replace <slot> with the number of the VISM-PR card that you want to upgrade.
Replace <revision> with the version of the boot code you downloaded from Step 1.
The following example shows the burnboot.
nodename.1.7.PXM.a > burnboot 12 3.2(1.0)
The card in slot 12 will be reset.
burnboot:Do you want to proceed (Yes/No)? yes
For VISM-PR cards without redundancy, the card automatically resets and becomes active with the latest boot code image.
For VISM-PR cards with redundancy, the active card takes approximately 60 seconds to reset as standby. For the original standby card, complete Step 2- Step 3. This card now resets back to standby, and the standby card is now active.
Upgrade VISM-PR Firmware with PXM1E and PXM45 Cards
Ensure that the VISM-PR cards have the minimum boot code version of VI8_BT_3.2.00.
The following versions of VISM-PR software Release 3.2 are available:
•003.002.000.000—without CALEA
•003.052.000.000—with CALEA
Perform the firmware upgrade on the VISM-PR cards.
Step 1 Log in to the active PXM1E or PXM45 card.
Step 2 Ensure that the card is in the redundant mode, where the active card is the primary card.
Step 3 To save the existing configuration as a contingency plan, enter the saveallcnf command.
nodename.1.7.PXM.a > saveallcnf
Step 4 To load the new software, enter the loadrev command.
nodename.1.7.PXM.a > loadrev <sm-primary-slot-num> <new-rev>
Replace <sm-primary-slot-num> with the slot number of the VISM-PR card on which you want to install the new software.
Replace <new-rev> with the new firmware version number for the VISM-PR software.
Caution Temporary traffic loss occurs.
Step 5 Ensure that the redundant card is returned to the standby state by executing the dspcds command.
Note You must wait for the redundant card to return to the standby state. If you issue the runrev command too early, an error message is generated. The rev change does not occur.
Step 6 To execute the download, enter the runrev command.
nodename.1.7.PXM.a > runrev <sm-primary-slot-num> <new-rev>
Replace <sm-primary-slot-num> with the slot number of the VISM-PR card on which you want to install the new software.
Replace <new-rev> with the new firmware version number for the VISM-PR software.
Caution Temporary traffic loss occurs.
Step 7 Ensure that the primary slot completes booting and goes into the standby state by executing the dspcds command.
Note You must wait for the primary slot to finish booting and get to standby state. Issuing the commitrev command early might be accepted without an error. However, the active and standby cards might not be swapped back to their original state. For example, the original primary card might be left in standby, and the original redundant card might be left as active.
Step 8 To commit the new download to the VISM-PR card, enter the commitrev command.
nodename.1.7.PXM.a > commitrev <sm-primary-slot-num> <new-rev>
Replace <sm-primary-slot-num> with the slot number of the VISM-PR card on which you want to install the new software.
Replace <new-rev> with the new firmware version number for the VISM-PR software.
The commitrev command switches the primary card from a standby state to an active state and the redundant card from an active state back to a standby state.
Step 9 To verify the card states, execute the dspcds command.
VISM/VISM-PR Downgrade Procedure
Use this procedure to downgrade VISM/VISM-PR software from software Release 3.2 to an earlier VISM/VISM-PR release. By following the downgrade procedure described here, the configurations are retained after the downgrade.
Note The configurations that existed with old-rev firmware should have been saved earlier. You cannot downgrade from VISM-PR to VISM.
Complete the following steps to downgrade the VISM/VISM-PR software from software Release 3.2 for VISM/VISM-PR to Release 3.1, 3.0, 2.2, 2.1, or 1.5:
Step 1 If the VISM/VISM-PR card is in a redundancy group, remove the redundancy.
nodename.1.7.PXM.a > delred <SM slot#>
Step 2 Download the old-rev firmware onto the MGX shelf.
Step 3 Execute the PXM clrsmcnf command:
nodename.1.7.PXM.a > clrsmcnf <SM slot#>
Replace <SM slot#> with the slot number of the VISM/VISM-PR card to be downgraded.
Wait for the card to become active. The VISM/VISM-PR card resets after you execute this command.
Step 4 Execute the PXM restoresmcnf command:
Caution The restoreallcnf command reconfigures all of the cards in the chassis.
nodename.1.7.PXM.a > restoresmcnf -f <filename> -s <SM slot#>
Replace <filename> with the name of the old configuration file that was saved while the old-rev firmware was running. The file can be found in the C:CNF directory on the MGX shelf.
Replace <SM slot#> with the slot number of the VISM/VISM-PR card to be downgraded.
The VISM/VISM-PR card resets again. The card becomes active, running the old-rev firmware with the old configuration.
Note For PXM1E/PXM45 cards, you cannot restore the configuration for an individual VISM-PR service module. You can save and restore the configuration of all cards in a chassis using the saveallcnf and restoreallcnf commands.
Step 5 Reconfigure the redundancy group, if required.
VISM to VISM-PR Hardware Upgrade
Complete the following steps to upgrade your system from VISM cards to VISM-PR cards.
Caution You must install the redundant (standby) VISM-PR card first. Failure to follow this recommendation results in traffic loss. In addition, do not remove an active VISM card from your chassis. Ensure that you configure an active VISM card to the standby state before you remove it and replace it with a VISM-PR card.
Step 1 Remove the redundant (standby) VISM card from your chassis.
Step 2 Install a VISM-PR card in the slot you removed the VISM card from in Step 1.
Step 3 Administratively configure the VISM-PR card you installed in Step 2 as primary (active).
Step 4 Remove the now redundant VISM card from your chassis.
Step 5 Install a VISM-PR card in the slot you removed the VISM card from in Step 4.
Step 6 Log in to the redundant (secondary) VISM-PR card and execute the dspcd command. Verify that the output from the dspcd command lists the card type under FunctionModuleType as a VISM-PR card. If the card type still indicates the VISM card, execute the resetcd slot-num command from the PXM and repeat the dspcd command to ensure that the correct card type is shown.
Step 7 Log in to the active VISM-PR card and execute the dspcd command. Verify that the output from the dspcd command lists the card type under FunctionModuleType as a VISM-PR card.
If the card type still indicates the VISM card, execute the resetcd slot-num command from the PXM. Repeat the dspcd command to ensure that the correct card type is shown.
Step 8 If you have no other VISM cards in your chassis, you have completed the hardware upgrade procedure; do not proceed to Step 9. If you have more VISM cards in your chassis, proceed to Step 9.
Step 9 Remove a standby VISM card from your chassis.
Step 10 Install a VISM-PR card in the slot you removed the VISM card from in Step 9.
Step 11 Repeat Step 9 and Step 10 to remove any remaining VISM cards in your chassis and replace them with VISM-PR cards.
Step 12 Repeat Step 6 and Step 7 on the remaining VISM-PR cards to insure the correct card type is shown.

If your issue is not resolved using the recommended resources, your case will be assigned to a Cisco TAC engineer. The online TAC Case Open Tool is located at this URL:

For P1 or P2 cases (P1 and P2 cases are those in which your production network is down or severely degraded) or if you do not have Internet access, contact Cisco TAC by telephone. Cisco TAC engineers are assigned immediately to P1 and P2 cases to help keep your business operations running smoothly.
To open a case 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: 1 800 553-2447For a complete listing of Cisco TAC contacts, go to this URL:

TAC Case Priority Definitions
To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.
Priority 1 (P1)—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.
Priority 2 (P2)—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.
Priority 3 (P3)—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.
Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
