Cisco Nexus Virtual Services Appliance Release Notes, Release 4.2(1)SP1(5.1a)

Published: November 26, 2012

This document describes the features, limitations, and caveats for the Cisco Nexus Virtual Services Appliance management software. Use this document in combination with documents listed in the “Related Documentation” section.

Contents

This document includes the following information about the Cisco Nexus Virtual Services Appliance management software.

Hardware Features

The Cisco Nexus Virtual Services 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.

There are two new appliances in the Cisco Nexus Virtual Services Appliance family:

  • The Cisco Nexus 1110-S appliance
  • The Cisco Nexus 1110-X appliance

Each of the new appliances is described in the following section.

Cisco Nexus Virtual Services Appliance Features

The Cisco Nexus 1110-S appliance has the following features:

  • Memory: 32 GB
  • Hard disk: Two 2-TB SATA drives
  • Support for up to 6 VSBs

The Cisco Nexus 1110-X appliance has the following features:

  • Memory: 64 GB
  • Hard disk: Four 4-TB SATA drives
  • Support for up to10 VSBs

Complete hardware feature descriptions and specifications are available in the Cisco Nexus Virtual Services Appliance Hardware Installation Guide.

Software Features

This section describes the following new or changed software features:

Information about these features can be found in the Cisco Nexus Virtual Services Appliance Software Configuration Guide and in the Cisco Nexus Virtual Services Appliance Troubleshooting Guide.

Enhanced Troubleshooting Capabilities

The following troubleshooting capabilities are available:

  • USB/CD Support for Troubleshooting

In the event of any failure on the Cisco Nexus Virtual Services Appliance or loss in network connectivity, you can access an external USB or CD to copy the logs for troubleshooting. To access an external USB or CD, you must enable the auxiliary feature. By default this feature is disabled.

  • Shutdown Command

A shutdown command is available to shut down the Cisco Nexus Virtual Services Appliance. When you execute this command, all the VSBs shut down first and then the Cisco Nexus Virtual Services Appliance shuts down. By default, the command shuts down both the primary and the secondary Cisco Nexus Virtual Services Appliance.

  • VSB Statistics

The show virtual-service-blade name name statistics command displays statistics for a specific virtual service blade (VSB) such as CPU utilization, memory, last reboot time, and total number of reboots.

  • Enhanced Log Collection

The vsa-system get agent logs command allows you to access agent logs, sos report, and other logs in the bootflash:repository.

  • Debug CD

The debug CD is a separate image for debugging purposes. It allows you to boot directly into the host operating system.

SNMP for PID

Each hardware PID is supported by its unique sysObjectId SNMP MIB. The following hardware PIDs exist: N1K-C1010, N1K-C1010-X, N1K-1110-S, and N1K-1110-X.

Software Compatibility

The Cisco Nexus Virtual Services Appliance management software controls the virtual services and blades running on the Cisco Nexus 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 Virtual Services Appliance Software Configuration Guide, Release 4.2(1)SP1(5.1) .

Cisco Nexus Virtual Services Appliance software is preinstalled as an ISO image that includes the following components:

  • Cisco Nexus Virtual Services Appliance kickstart image
    This is the Cisco Nexus Virtual Services Appliance Management Software.

The Cisco Nexus Virtual Services Appliance management software is compatible with the following software versions:

  • Cisco Nexus 1000V: All releases (no dependency)
  • Cisco Network Analysis Module (NAM) Release 5.1.2 and later
  • Cisco Virtual Security Gateway (VSG) Release 4.2(1)VSG1(3.1) and later

The Cisco Nexus Virtual Services Appliance management software works with all Ethernet switches.

Limitations and Restrictions

Configuration Limits

The Cisco Nexus 1110-S VSA maximum supported configuration (up to six VSBs total) is either:

  • 6 Cisco Nexus 1000V VSMs, each capable of managing 64 VMware ESX or ESXi hosts for a total of 384 VMware ESX or ESXi hosts
  • 6 Cisco Virtual Security Gateway (VSG) VSBs

The Cisco Nexus 1110-X VSA maximum supported configuration (up to 10 VSBs total) is either:

  • 10 Cisco Nexus 1000V VSMs, each capable of managing 64 VMware ESX or ESXi hosts for a total of 640 VMware ESX or ESXi hosts
  • 10 Cisco VSG VSBs

Table 1 provides a weighting matrix that can be used to determine the maximum capacity of VSBs on the Cisco Nexus Virtual Services Appliance.

No Error Message for Upgrade Failure

If an upgrade to Cisco Nexus Virtual Services Appliance Release 4.2(1)SP1(5.1) from an earlier release of the Cisco Nexus 1010 Management Software fails, no error message is displayed. This limitation is associated with CSCub39408.

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 Virtual Services Appliance 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.
