Created Release Notes for Release 4.2(1)SP1(2)
This document includes the following information about the Cisco Nexus 1010 management software.
This section describes the following new software features:
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 four Cisco Nexus 1000V VSMs and a Cisco Network Analysis Module (NAM).
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.
•Hypervisor (KVM Linux) with a Cisco Nexus 1010 agent
Virtual Supervisor Module
The Cisco Nexus 1010 Management Software can manage up to four 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 current version is bundled as an ISO image and included in the Cisco Nexus 1010 repository folder in the bootflash directory.
For more information about creating virtual services, see the Cisco Nexus 1010 Software Configuration Guide, Release 4.2(1)SP1(2).
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.
To create a NAM virtual service see the Cisco Nexus 1010 Software Configuration Guide, Release 4.2(1)SP1(2).
For more information about Cisco NAM, see the Cisco Network Analysis Module Software Documentation Guide, 4.2.
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
The Cisco Nexus 1010 management software works with all Ethernet switches.
