These release notes describe the open and resolved caveats in system software Version 5.2(2) for the Cisco Systems VCO/4K switch. There are no new features introduced with this release. Use these release notes in conjunction with the Cisco VCO/4K Software Installation Guide, the Cisco VCO/4K System Administrator's Guide, and Cisco VCO/4K System Messages.
These release notes contain the following sections:
This section provides system requirements for operating VCO/4K system software. These requirements are categorized by hardware, firmware, and software. Contact Cisco Systems Technical Assistance Center (TAC) for any site-specific information.
To operate VCO/4K system software Version 5.2(2), make sure your Cisco VCO/4K switch is equipped with the following minimum components and revisions:
Refer to the Cisco VCO/4K CPU Upgrade Procedure if you need to replace a 25-MHz/8-MB CPU with a 33-MHz/16-MB CPU.
Two NBC3 cards are required for redundant systems.
Table 1 lists the VCO/4K system software Version 5.2(2) firmware requirements. Refer to the Cisco VCO/4K Card Technical Descriptions for firmware locations for each card.
For tone plan-specific firmware requirements (which affect DTG2 or DTG cards), refer to the Cisco VCO/4K Tone Plan Release Notes.
Note The firmware label applied by Cisco Systems may list only the last four digits of the checksum. The checksum for the NBC3 LP125 is not listed because the programming for this item is part of the NBC3 download file. |
Table 2 lists valid software checksums and versions for the VCO/4K system software Version 5.2(2) and optional software products.
Use the Software/Firmware Configuration utility to identify the version and checksum of each software file after Version 5.2(2) has been installed on the system (refer to the Cisco VCO/4K System Administrator's Guide for more information). System software files are distributed across the installation floppy diskettes. Optional software products are contained on two floppy diskettes.
Table 2 VCO/4K System Software Version 5.2(2) Checksum Values
|
1 The software no longer lists the individual executable file (.EXE) version numbers in the Software/Firmware Configuration screen. A "—" character in the File Version column signifies that the file version matches the system software release, for example, Version 5.2. If a version number appears in the File Version column for an .EXE file, it is strictly for reference purposes; it does not appear in the Software/Firmware Configuration screen. 2 The checksum values for .upg files (protocol files) are displayed by accessing the Display File screen. Go to Maintenance Menu > Disk Utilities > Display File, and type: c:boot/<filename>. The .upg file checksum value is displayed in the first four bytes of the second row. 3 The VCO.MIB file is not installed on the switch; it is intended for the SNMP host system. |
VCO/4K system software Version 5.2(2) is a maintenance release which includes several caveat resolutions. Refer to the "Caveats" section for more information on resolved caveats.
This release contains an enhancement for the Password Configuration screen, which allows you to change SNMP read and write community strings of up to ten characters. See the "Changeable SNMP Community Strings" section.
Diskettes containing Version 5.2(2) system software are not provided. You must complete the procedures in the following sections to make your diskettes:
The Password Configuration screen allows you to change SNMP read and write community strings with the previous release, VCO/4K system software Version 5.2(1). The Version 5.2(2) release increases the password length from eight to ten uppercase and/or lowercase alphanumeric characters.
Complete the following steps to configure SNMP community strings:
Step 2 Delete the following two usernames:
Step 3 Add and save the two usernames you deleted in Step 2.
The password of the snmpget serves as the SNMP GET community string, and the password of the snmpset serves as the SNMP SET community string.
Step 4 Establish passwords for the usernames added in Step 3. Refer to the Cisco VCO/4K System Administrator's Guide for instructions.
Note Passwords must consist of up to ten uppercase and/or lowercase alphanumeric characters. If you type a password more than twelve characters, the tenth character is overwritten until you stop typing. Follow all existing user password restrictions described in the Cisco VCO/4K System Administrator's Guide. |
The passwords are displayed as asterisks (*) on your screen.
Step 5 Change your passwords as often as necessary.
The SNMP community string configuration is complete. The VCO/4K system compares the passwords of the snmpget and snmpset usernames with the community strings given by incoming SNMP request messages—community strings used by the network management station (NMS) for GET and SET commands.

If you are using the VCO/4K product for Communication Assistance for Law Enforcement Act (CALEA) conferencing, you must administratively detach each CALEA one-way port when the CALEA conference is completed. CALEA one-way conference ports remain in the Class of Service (COS) state of 2C if you do not detach them, which makes them unavailable for other calls. Refer to the Cisco VCO/4K System Administrator's Guide for information about administratively detaching ports.
Table 3 lists the design constraints which have been identified in VCO/4K system software and related software. Unless noted, these limitations and restrictions apply to all Cisco VCO/4K releases up to and including 5.2(2). Cisco Systems currently has no plans to address the following known design constraints.
Table 3 Known Design Constraints up to and Including Version 5.2(2)
This section contains important information for operating the VCO/4K system efficiently. The following sections are included to enhance configuration and performance:
If you are upgrading from VCO/4K system software Version 5.1(4) or lower, you must complete a database conversion immediately after upgrading to VCO/4K system software Version 5.2(0) and higher. Refer to the Cisco VCO/4K Software Installation Guide for database conversion procedures.
Note The database conversion is performed by the system without the usual advisory system messages. |
You can use Live Upgrade to upgrade to system software Version 5.2(2); however, refer to the following two sections for version-specific workaround procedures.
Caution Do not operate conferences on the VCO/4K system while performing a Live Upgrade. Failure to follow this guideline may result in loss of calls. Ensure that the host is not sending Conference Control ($6D) commands to the VCO/4K system during the system reset/file synchronization phase of the Live Upgrade procedure. Refer to Step 5 through Step 11 in the "Perform a Live Upgrade" section of the Cisco VCO/4K Software Installation Guide for more information. |
Complete the following steps to use Live Upgrade if you are using system software Version 4.2 and higher. This procedure is a workaround for DDTs issue CSCdp23217—Live Upgrade failure with a Process Event Handler.
Caution If you are using system software from Version 5.0.0.25 through Version 5.1.0.26, you must complete the following steps, and the steps in the "Live Upgrade Procedures from Version 5.0.(0.25) through Version 5.1.(0.26) with SPCs" section, so that you do not lose all calls. |
Caution Do not access the Software/Firmware Configuration screen at any time during Live Upgrade procedures. Failure to follow this instruction results in Live Upgrade failure. Proceed to Step 1; do not deviate from these procedures. |
Step 2 Wait for file synchronization and perform a switchover.
Step 3 Boot the new standby side and wait for file synchronization.
Step 4 Follow the Live Upgrade procedures in the Cisco VCO/4K Software Installation Guide.
Complete the following steps to use Live Upgrade from system software Version 5.0.(0.25) through Version 5.1.(0.26). This procedure prevents DSP failure on switchover and is a workaround for DDTs issue CSCdm22671.
Caution Follow this workaround procedure when using Live Upgrade from Version 5.0.(0.25) through Version 5.1.(0.26). Failure to do so will result in the loss of all calls that require SPC resources. Use this procedure to minimize the volume of lost calls, limiting them to calls that are active on the SPC and that are taken out of service in order to reflash. |
Step 2 Take one SPC out of service (OOS).
Step 3 Place the same SPC in the active state.
Step 4 Wait for the download to complete and all DSPs to become active on the SPC.
Step 5 Repeat Step 2 through Step 4 for all other SPCs, one at a time.
Step 6 Follow the Live Upgrade procedures in the Cisco VCO/4K Software Installation Guide.
When an ICC-T1 ISDN span is configured as the primary timing source, the incoming clock on the ICC-T1 ISDN fails to synchronize if you are upgrading from an existing database—prior to system software Version 5.1(1)—to a new database in VCO/4K system software Version 5.2(1).
To utilize your existing ICC-T1 ISDN (NI2, 4ESS, 5ESS, NTI, NTT) span as the primary timing source, complete the following steps when you upgrade to 5.2(2).
Note You do not need to perform the following procedure if you are adding a new T1 span as the primary timing source to the database or if you are currently running system software Version 5.1(1) or higher. |
Note When you upgrade your software to 5.2(2), Cisco Systems recommends that you perform this procedure on the ICC-T1 ISDN spans configured as the primary and secondary timing source. |
Step 2 From the ICC ISDN Span Configuration screen, perform the following steps:
a. Change the REF CLOCK field parameter from LOOP to 1544.
Step 3 Return the ICC-T1 ISDN span (from Step 1) back in service.
