This document includes the following information about the Cisco Nexus 1010 management software.
Hardware Features
The Cisco Nexus 1010-X appliance (N1K-C1010-X) is a new version of the Cisco Nexus 1010 Virtual Services Appliance. Like the Cisco Nexus 1010, the Cisco Nexus 1010-X appliance is a hardware shell that can host multiple virtual service blades (VSBs), including up to four Cisco Nexus 1000V virtual supervisor modules (VSMs) and a network analysis module (NAM). From a network management perspective, the hosted VSMs appear as a cluster. Each VSM and its associated VEMs make up one virtual switch.
Both the Cisco Nexus 1010 and the Nexus 1010-X can host the VSM, the VSG, the NAM, and Cisco DCNM.
Cisco Nexus 1010-X Features
The Cisco Nexus 1010-X appliance has the following features:
•Memory: 48 GB
•Hard disk: Two 2-TB SAS drives
•Support for up to 10 VSBs
By comparison, the Cisco Nexus 1010 appliance has the following features:
•Memory: 16 GB
•Hard disk: One TB SATA
•Support for up to 6 VSBs (limited by the available RAM on the Cisco Nexus 1010.
All other features and specifications match those listed for the Cisco Nexus 1010 appliance in the Cisco Nexus 1010 Virtual Services Appliance Hardware Installation Guide.
High Availability With the Cisco Nexus 1010-X Appliance
The Cisco Nexus 1010-X appliance must be deployed in a highly-available (HA) configuration with another Cisco Nexus 1010-X appliance. Standalone deployments of the Cisco Nexus 1010-X are not supported.
The Cisco Nexus 1010-X appliance and a Cisco Nexus 1010 appliance, cannot be deployed together to form an HA pair. The hardware must be the same for the HA pair.
After you install the Cisco Nexus 1010-X, you can move, or migrate your VSBs from a Cisco Nexus 1010 to the Cisco Nexus 1010-X appliance. The migration includes the following steps:
1. Verify that the Cisco Nexus 1010 has the VSBs configured that need to be migrated to the Cisco Nexus 1010-X.
2. Set up the Cisco Nexus 1010-X in a redundant HA pair.
3. Migrate the HA VSBs like VSM and VSG to a Cisco Nexus 1010-X.
4. Migrate the non-HA VSBs like NAM and Cisco DCNM to the Cisco Nexus 1010-X.
For detailed information about these steps, see the Cisco Nexus 1010 Software Configuration Guide.
Software Features
This section describes the following new or changed software features:
•IPv6 Address Support for the Management Port
IPv6 Address Support for the Management Port
This release supports IPv6 addressing for the management (mgmt0) port. You can enter the IPv6 address for the management port when you run the setup script for the Cisco Nexus 1010 switch.
For additional information, see the Cisco Nexus 1010 Software Installation and Upgrade Guide, Release 4.2(1)SP1(4a).
Software Compatibility
The Cisco Nexus 1010 management software controls the virtual services and blades running on the Cisco Nexus 1010 Virtual Services Appliance. These include up to six Cisco Nexus 1000V VSMs, a NAM, and up to three VSGs.
For more information about modules, see the Cisco Nexus 1010 Software Configuration Guide, Release 4.2(1)SP1(4).
Cisco Nexus 1010 software is pre installed as an ISO image that includes the following components:
•Cisco Nexus 1010 kickstart image
This is the Cisco Nexus 1010 Management Software.The Cisco Nexus 1010 management software is compatible with the following minimum software versions:
•Cisco Nexus 1000V Release 4.0(4)SV1(3)
•Cisco Network Analysis Module Release 4.2.1
•Cisco Virtual Security Gateway Module Release 4.2(1)VSG1(2)
The Cisco Nexus 1010 management software works with all Ethernet switches.
Limitations and Restrictions
•Domain ID and HA Role Cannot Be Changed
•Boot Variables Cannot Be Manually Configured
•Changing the Control or Mgmt VLAN Requires a Reload
Configuration Limits
Use the following configuration limits for the Cisco Nexus 1010:

Domain ID and HA Role Cannot Be Changed
The configured domain ID and high availability (HA) role (standalone, primary, or secondary) can never be changed. To change the domain ID or the HA role, you must use the write erase command.
Boot Variables Cannot Be Manually Configured
The boot variables cannot be configured manually. To change the boot variables, you must enter the install nexus1010 command. This command installs the software from the bootflash:/repository directory and updates the boot variables with the name of the software image.
Changing the Control or Mgmt VLAN Requires a Reload
If you change the control or management VLAN, you must reload the software before the change takes effect.
DNS Resolution
The Cisco Nexus 1010 (1000V) cannot resolve a domain name or hostname to an IP address.
No Local Copy in bootflash:export-import
Do not make a copy of the tar files in the export-import folder. Copying files locally might cause a split-brain condition and lead to HA issues.
Always copy the tar files to remote storage after entering the export command and then delete it from export-import folder.
