The Cisco Nexus 1000V provides a distributed, layer 2 virtual switch that extends across many virtualized hosts. The Cisco Nexus 1000V manages a Datacenter defined by the vCenter Server. Each server in the Datacenter is represented as a linecard in Cisco Nexus 1000V and can be managed as if it were a line card in a physical Cisco switch.
Cisco Nexus 1000V consists of the following two components:
Virtual Supervisor Module (VSM), which contains the Cisco CLI, configuration, and high-level features
Virtual Ethernet Module (VEM), which acts as a Line Card and runs in each virtualized server to handle packet forwarding and other localized functions.
The following software features are new in this release:
• GUI Set Up Following Software Installation
• Layer 3 Control
• Virtual Service Domain
• iSCSI Multipath
• XML API
• DHCP Snooping
• Dynamic ARP Inspection
• IP Source Guard
• MAC Pinning
• Static Pinning
This document describes the features, limitations, and caveats for the Cisco Nexus 1000V Release 4.0(4)SV1(2) software.
