The following information details existing device issues that have been discovered within other releases. In most cases, a resolution is included to address the issue.

Cisco IOS - Out-of-Sync

  • When a SNMP/TFTP mechanism is used with only a Community String credential, the Running against Startup Configuration Out-of-Sync icon is not displayed. A valid Account and/or Privilege Password credential is needed to pull the Startup configuration on Cisco IOS devices.

    Cisco IOS Update

  • Issue: An issue exists where the OS image resided in bootflash, but was not the boot loader image. Additionally, the system image file was not in the show version command. In this case, the application could not free space in the target location. Manual intervention is needed to free space.

    When there is insufficient space in the target location for an OS update on Cisco IOS devices with Class A file systems, the system attempts to free up additional space by deleting and squeezing the system image name displayed in the show version command.

    For example:

    r2621-vpn uptime is 6 weeks, 5 days, 1 hour, 0 minutes

    System returned to ROM by reload

    System image file is "flash:c2600-ik9o3s3-mz.122-15.T9.bin"

  • Resolution: Manually, complete a delete and squeeze on that filename before beginning the OS update.

    Cisco 3845

  • Memory is not currently supported for the Cisco 3845.

    Cisco 7206

  • Issue: Cisco Model 7206 does not correctly display the Hardware Controller I/O Controller version. It incorrectly displays the version as 0.0. This issue is present with IOS Version 12.0(4)XE2, and not in Version 12.2(25)S2.

  • Resolution: Cisco Model 7206 should be upgraded to a new IOS version.

    TFTP Pushes May Fail Silently

  • Silent configuration command failures may occur when using any of the TFTP transfer methods (snmp/tftp, ssh/tftp, or telnet/tftp). Error status, if any, is being missed from the device following the transfer.

    TACACS+ Implementation

  • Issue: Some versions of IOS have a TACACS+ implementation issue that causes additional characters to be added to the login User Name. When this occurs, it may cause occasional login failures.

  • Resolution: Modify a custom version of the stdlib/ file to issue a backspace character before the username as shown below.

    1. Make a directory named $VOYENCE_HOME/custompackage/stdlib

    2. Copy the file $VOYENCE_HOME/package/stdlib/ to $VOYENCE_HOME/custompackage/stdlib/

    3. Change the termLogin() function in this new file:

    4. Search for: send(session,userId+stdEOL,true);

    5. Change to: send(session,asc(0x08)+userId+stdEOL,true);

    6. After making the change, restart the device server services.

      Cisco IOS Router - Running Configuration Contents

  • Running configuration contents of the following form must be removed prior to pushing, or the resulting job will fail based on “Invalid input” messages from the device when the data values following the “certificate self-signed” line are processed:

    crypto pki certificate chain TP-self-signed-2725887360

    certificate self-signed 01
