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

A Cisco Nexus 1010-X appliance can be deployed with another Cisco Nexus 1010-X appliance to achieve high availability (HA); however, a 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:

Virtual Supervisor Module

Network Analysis Module

Virtual Security Gateway Module

High Availability

CDP Neighbors

VSB Export and Import

Virtual Supervisor Module

The Cisco Nexus 1010 Management Software can manage up to six virtual supervisor modules (VSMs), each controlling a group of virtual Ethernet modules (VEMs). If you are using Layer 3 Control, the VEMs can also be in different Layer 3 domains. From a network management perspective. a VSM and the VEMs it controls make up a virtual switch; and the Cisco Nexus 1010 and the multiple virtual switches it hosts are viewed as a cluster of switches.

You can create redundant VSMs on the Cisco Nexus 1010 with the Cisco Nexus 1000V software image. The 4.0(4)SV1(3) version is bundled as an ISO image and included in the Cisco Nexus 1010 repository folder in the bootflash directory. You can download the current version from the following URL:

www.cisco.com/go/1010download

For more information about creating virtual services, see the Cisco Nexus 1010 Software Configuration Guide, Release 4.2(1)SP1(3).

Network Analysis Module

You can create a network analysis module (NAM) on the Cisco Nexus 1010 with the NAM ISO image included in the Cisco Nexus 1010 repository folder in the bootflash directory; or you can download the current version from the following URL:

www.cisco.com/go/1010download

To create a NAM virtual service see the Cisco Nexus 1010 Software Configuration Guide, Release 4.2(1)SP1(3).

For more information about Cisco NAM, see the Cisco Network Analysis Module Software Documentation Guide, 4.2.

Virtual Security Gateway Module

You can create up to three virtual security gateway (VSG) modules on the Cisco Nexus 1010 with the VSG ISO image. You can download the VSG ISO image from the following link.

www.cisco.com/go/1010download

To create a VSB for VSG, see the Cisco Nexus 1010 Software Configuration Guide, Release 4.2(1)SP1(3).

For more information about VSG, see the Cisco Virtual Security Gateway for Nexus 1000V Series Switch Configuration Guide, Release 4.2(1)VSG1(2).

High Availability

If control connectivity is lost for the Cisco Nexus 1010, but management connectivity is preserved, the active Cisco Nexus 1010 reloads the standby once. The standby comes up in wait state until control connectivity is restored.

During the period of lost connectivity, you can perform all operations on the active VSM.

CDP Neighbors

You can use the following new CLI command to see either the active or standby Cisco Nexus 1010 uplink connectivity.

show network cdp neighbors detail

For more information about this new command, see the Cisco Nexus 1010 Command Reference, Release 4.2(1)SP1(3).

VSB Export and Import

You can export and then import a VSB configuration from the Cisco Nexus 1010 in case you need to recover an unreachable VSM or migrate a VSM. The following new commands support VSB export and import:

export [primary | secondary]

import [primary |secondary] filename

interface VsbEthernet [slot-id | vsb-id | interface-id]

[no] shutdown (for VSB interfaces)

For more information about VSB export and import, see the Cisco Nexus 1010 Software Configuration Guide, Release 4.2(1)SP1(3).

For information about new commands, see the Cisco Nexus 1010 Command Reference, Release 4.2(1)SP1(3).

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(3).

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.

Domain ID and HA Role Cannot Be Changed

The configured domain ID and high availablility (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.
