Note Loading this release of the backup boot code is required for existing VISM/VISM-PR cards not using this new release.
Limitations and Restrictions
The following limitations and restrictions are valid for software Release 3.3.20 for VISM/VISM-PR:
•If you are upgrading the VISM-PR image to Release 3.2.1x or later and the PXM1E or PXM45 image from Release 4.x or earlier to Release 5.x, first upgrade the VISM-PR cards. Then, upgrade the PXM1E or PXM45 cards in the same node.
Do not configure the new VISM features until you have fully upgraded the network. After you upgrade your network to PXM1E or PXM45 Release 5.x or later and VISM-PR to Release 3.2.1x or later, apply the standard upgrade process.
•Cisco recommends that you use the cnfcodecjtrdelay command to configure the fixed jitter-delay argument to 20 ms when using VISM 3.3.20.
•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, you must disable policing.
•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 the VISM cards are dropped upon PXM hard and soft switchover.
•For VISM-PR cards that are running on a PXM45 chassis, you can add connections to a maximum of 11 VISM-PR cards.
To add more cards and connections, you must enable the expanded memory option on the PXM45 card by using the cnfndparms (option 4) command.
•When configuring VoIP for modem or fax upspeed (passthrough), set the EventNegoPolicy parameter of the cnfvoiptransparams command to the value all.
This configuration is required for all related upspeed codecs to function correctly. An upspeed codec is defined as the codec that is switched to G.711a/u law, Clear Channel, or G.726.
•For a list of open issues and mitigations in VISM Release 3.3.20, see "Caveats in Release 3.3.20" section.
Upgrade Procedures
This section describes the following upgrade procedures:
• Prerequisites
• VISM/VISM-PR Upgrades with PXM1
• VISM-PR Upgrades with PXM1E and PXM45
• VISM/VISM-PR Downgrade Procedure
• VISM to VISM-PR Hardware Upgrade
VISM/VISM-PR Release 3.3.20 provides a procedure for the graceful upgrade (one in which the existing VISM/VISM-PR configuration is preserved throughout the upgrade procedure) from one of the following releases:
•From VISM 3.1.2 to VISM 3.3.20
•From VISM 3.1.3 to VISM 3.3.20
•From VISM 3.2.11 to VISM 3.3.20
•From VISM 3.3 to VISM 3.3.20
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 3.3.20 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.
•Before you upgrade to 3.3.20, delete all domain names that are greater than 32 characters on the VISM/VISM-PR card. See the Check Domain Name Length section. After you complete the upgrade to 3.3.20, add the domain names that are greater than 32 characters.
Check Domain Name Length
Before you upgrade to 3.3.20, delete all domain names and domain name IPs that are greater than 32 characters on the VISM/VISM-PR card. After the upgrade, re-add the domain names and domain name IPs.
Complete the following steps.
Step 1 Log in to the VISM/VISM-PR card.
Step 2 Display the list of domain names by entering the dspdns command.
MGX1E.1.11.VISM8.a > dspdns
DomainNumber DomainName ResolutionType
------------ -------------- --------------
1 mga-SOLSYS1CA.234567890987654321234567890123456789.sol.cisco.com internalOnly

Step 5 If IP addresses are present, make a note of them in the order that they appear.
Step 6 Since you cannot delete the domain name or domain name IPs if MGCs exist, use the following commands to check for MGCs and delete them if they exist for each domain name:
a. Check for the MGC group protocols by entering the dspmgcgrpprotocols command.
MGX1E.1.11.VISM8.a > dspmgcgrpprotocols

1 mga-SOLSYS1CA.234567890987654321234567890123456789.sol.cisco.co
Step 7 If any entries exist for the domain name in Step 6 a. to Step 6 c., delete the MGC entries by entering the following commands as required:
•delmgcgrpprotocol
•delmggrpentry
•delmgc
Step 8 Delete the domain name IP address by entering the deldnip command.
Step 9 Delete the domain name by entering the deldn command.
Step 10 Perform the upgrade using the procedures in the "Upgrade VISM/VISM-PR Firmware with PXM1 Card" section or "Upgrade VISM-PR Firmware with PXM1E and PXM45 Cards" section.
Step 11 After you complete the upgrade, add the domain name entries, IP addresses, and MGCs as previously configured using the following commands:
•adddn
•adddnip
•addmgc
•addmgcgrpentry
•addmgcgrpprotocol
Step 12 To check that you added the entries successfully, use the display commands in Step 2 to Step 6.
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 bootcode 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.
a. tftp <node_name or IP address>
b. bin
c. To upgrade all VISM cards:
put <FW file> POPEYE@SM_1_0.FW
quit
d. To upgrade an individual VISM card:
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:
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 3.3.20 is for VISM and VISM-PR cards. Ensure that the VISM and VISM-PR cards have the minimum boot code version of vism_8t1e1_VI8_BT_3.2.00.fw.
The following versions of VISM software Release 3.3.20 are available:
•003.003.020.201.FW—without CALEA
•003.053.020.201.FW—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 3.2 and prior.
•New-rev refers to the firmware after the upgrade, Release 3.3.20.
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:
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

VISM-8T1E1 05/10/2005 08:20:58 4037880 003.003.020.000 sm150.fw
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, 003.003.020.201.FW).
The install sm 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.
Caution Ensure that you perform
Step 4. If you do not perform
Step 4, the boot code is corrupted and not recoverable.
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.
The newrev command causes the primary VISM or VISM-PR card to reset. The secondary VISM or VISM-PR card becomes active and runs 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 only
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.
If you are upgrading the VISM-PR image to Release 3.2.1x or later and the PXM1E or PXM45 image from Release 4.x or earlier to Release 5.x, first upgrade the VISM-PR cards. Then, upgrade the PXM1E or PXM45 cards in the same node.
Do not configure the new VISM features until you have fully upgraded the network. After you upgrade your network to PXM1E or PXM45 Release 5.x or later and VISM-PR to Release 3.2.1x or later, apply the standard upgrade process.
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 boot code and firmware images on Cisco.com.
Step 2 To download the images, enter the ftp command.
ftp node-ip
The node-ip argument 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 Change to the C:FW directory.
cd C:FW
Step 6 Download the images 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.
The image-version argument is the image that you accessed in 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" section.
Step 2 Log in to the active 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 bootcode you downloaded from Step 1.
The following example shows sample results from the burnboot command.
nodename.1.7.PXM.a > burnboot 12 3.2(0.0)
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 and becomes the standby again, and the standby card is now active.
Upgrade VISM-PR Firmware with PXM1E and PXM45 Cards
Complete the steps in this section to upgrade the VISM-PR firmware. Ensure that the VISM-PR cards have the minimum boot code version of vism_8t1e1_VI8_BT_3.2.00.fw.
The following versions of VISM-PR software Release 3.3.20 are available:
•003.003.020.201.FW—Without CALEA
•003.053.020.201.FW—With CALEA
Caution If you plan to upgrade PXM cards and VISM-PR modules, upgrade the PXM cards first. Wait until the PXM cards are operating in active and standby modes with the correct software before upgrading the VISM-PR modules. Failing to upgrade the node in the correct order can fail VISM connections, causing significant service disruption.
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, 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 card completes booting up and goes into the standby state by executing the dspcds command.
Note You must wait for the primary card to finish booting up 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 states. 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 3.3.20 to an earlier VISM/VISM-PR release. If you use the downgrade procedure described here, you can retain the configurations 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:
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.
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.
Caution The
restoreallcnf command reconfigures all of the cards in the chassis.
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 For this procedure, 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 change 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 its slot in your chassis.
Step 2 Install a VISM-PR card in the same slot.
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 from which you removed the VISM card 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 its slot in your chassis.
Step 10 Install a VISM-PR card in the same slot.
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 ensure that the correct card type is shown for each.

DDTS Issue
|
Description
|
CSCeh72843
|
Symptom: CLI dspconcnt shows false AAL5 statistics when AAL2 CIDs have been deleted and re-added.
Conditions: This symptom occurs with the following conditions:
•AAL2 trunking
•CIDs added, deleted and re-added
•Releases 3.3.10 and earlier
Workaround: Do not delete and re-add CIDs.
Issue the clrsmcnf command and reconfigure the card if CIDs are changed and statistics are needed.
|
CSCei25172
|
Symptom: VISM lines are stuck in AIS.
Conditions: VISM-PR-8T1 is configured for AAL2 trunking and has CID. When the DS3 links go down and come back up, the VISM line remains stuck in AIS alarm.
Workaround: Disconnect and then reconnect the VISM cable.
|
CSCei30249
|
Symptom: VISM resets itself upon receiving RTP packets with different SSRCs on each RTP packet.
Conditions: The symptom happens only when VISM receives RTP packets with different SSRCs on each RTP packet.
This condition occurred with 12.3.4T6 on one of its IAD 2431 to create the problem.
Workaround: Fix the issue on the other side of the RTP session so that the correct SSRCs are used.
|
CSCei54326
|
Symptom: VISM stops sending RTCP packets after cnfgwoos forceful.
Conditions: RTCP packets are not sent from VISM for any of the calls when the VISM meets the following conditions:
1. One hundred or more active calls exist.
2. The gateway is forcefully taken out of service: cnfgwoos 2
3. The gateway is put back in service: cnfgwis
Workaround: Take the gateway gracefully out of service: cnfgwoos 3
|
CSCei54618
|
Symptom: Discrepancy in the VISM statistical information.
Conditions: The issue was observed with the CTM /MGM 5.0 Element Management on the MGX 8850 with VISM-PR-8T1/E1 Release 3.3.10.
Workaround: Use SNMP to get the current real-time and last 15 minute statistics for unavailable seconds (UAS) statistics.
Further Problem Description: The incorrect report value is of the UAS that is calculated by the VISM-PR.
|
CSCei61996
|
Symptom: VQT Stats: Latency is different between each direction of a call. During the early stage of a call, the A-->B and B-->A directions of a call report different values of latency.
Conditions: This symptom occurs with the following conditions:
•VAD ON
•Fixed jitter buffer
•Timestamp disabled
•VoIP switching mode
Workaround: Use one of the following workarounds:
1. Fixed jitter buffer mode with timestamp enabled
2. Adaptive jitter buffer mode
3. VAD disabled
|
CSCei85965
|
Symptom: CIDs are put in OOS as a result of insufficient bandwidth.
Conditions: Subsequent CIDs will be put in OOS after a card reset.
Workaround: Increase the bandwidth on the PVC.
