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

Cisco Nexus

  • The driver supports the MDS series running NX-OS if Nexus or NX-OS appears in the show version response, and the driver is successful in determining the identity, system properties, and interfaces for the device.

  • The management VRF must have a default route configured or file transfers will fail.

  • If the command “system default switchport” appears literally in the configuration, it must be removed or commented out before pushing with terminal, or the resulting % Incomplete command message will be treated as a failure, although the push content will be accepted. Same is the case with commands "switchport", "switchport mode fex-fabric" and "spanning-tree port type edge" in case of Cisco Nexus 7010 with 5.1(4) version.

  • Privilege account rolls are not supported because accounts are role based, and credentials are give network-admin privileges. Any attempt to execute a job including privilege credential changes will fail.

  • IP addresses and ARP table entries are not reported using SNMP.

  • Config Change Detection is only supported using syslog monitoring.

  • Switches running 4.0(4)SV1(1) have been observed to intermittently fail account credential rolls when both the account and password are changed.

    • A failsafe in the device prevents deletion of the original account, if the account is logged in.

    • The driver executes a show users command if this message is detected, but the account does not appear in the response.

    • Currently, only the account password can be successfully changed. This behavior is not observed on the hardware products.

  • Push to start is not supported.

    • The copy tftp startup command is deprecated.

    • The config content is silently ignored, although the job shows as successful in the scheduler.

    • The recommended Cisco procedure of write erase, reload, copy tftp running cannot be implemented due to a high probability of the application and managed device being located on different subnets.

  • Delete and Backup options are not available for OS Upgrade.

  • In the case of SCP, copy of images takes about 10-15 minites whereas via FTP, it takes only 1 to 2 minutes.

  • The driver will attempt to reconnect once during upgrade when the session is lost due to switchover:

    • The "show install all status" command is run if the session is successfully re-established. This command does not return to a command prompt on its own; Ctrl+C is required and is issued if the success message is encountered.

    • In the event that it is not, the session will timeout after 15 minutes with no significant progress messages. The upgrade itself may in fact succeed, but NCM will mark the job as failed.

    • The upgrade output is not currently analyzed to automate reboot of the CMP modules in the event that this is needed to complete the upgrade. This step must be performed manually (i.e., via cut-thru or by an external login).

      Cisco Nexus 1000V

  • The Nexus 1000v may not report IP addresses in the Interfaces tab, due to a limitation in the SNMP agent of the device.

  • The Nexus 1000V virtual switch running 4.0(4)SV1(1) has been found to include commands that cannot be pushed back to the device from the command-line interface. Such content must be commented out or removed prior to scheduling a full configuration push or the job will fail (though other changes will effectively succeed). This behavior has not been observed for pushes using TFTP.

    An example of these commands is included below; other forms may occur as well.

    • limit-resource u4route-mem minimum 32 maximum 80

    • limit-resource u6route-mem minimum 16 maximum 48
