• Advanced Cisco® NX-OS Software feature set and associated partner ecosystem
• Innovative network services architecture to support scalable, multitenant environments
• Consistent operating model across physical and virtual environments and across hypervisors
• Tight integration with Microsoft System Center Virtual Machine Manager (SCVMM) 2012 SP1
Figure 1. Cisco Nexus 1000V Switch for Microsoft Hyper-V Components
• The Cisco Nexus 1000V virtual Ethernet module (VEM) is a software component deployed on each Microsoft Hyper-V host as a forwarding extension. Each virtual machine on the host is connected to the VEM through virtual Ethernet (vEth) ports.
• The Cisco Nexus 1000V virtual supervisor module (VSM) is the management component that controls multiple VEMs and helps in the definition of virtual machine-focused network policies. It is a virtual machine running Cisco NX-OS on a Microsoft Hyper-V host and is similar to the supervisor module on a physical modular switch.
• Preserve your existing investments in operational processes and management tools.
– Network administrators can manage network policies across both physical and virtual environments using the same interfaces, and staff does not need to be retrained.
– Customers can use existing network monitoring, management, and troubleshooting tools to manage both physical and virtual environments.
• Simplify your virtual networking operations.
– Visibility into the traffic between virtual machines simplifies network troubleshooting.
– Virtualization-aware networking features simplify virtual machine network policy management.
– Tight integration with Microsoft SCVMM allows faster policy provisioning.
• Provide better security.
– Virtualization-aware networking provides better security by extending network policies and network visibility to the virtual machine level.
• Advanced switching features such as private virtual LANs (PVLANs), quality of service (QoS), access control lists (ACLs), port security, and Cisco vPath
• Security features such as Dynamic Host Configuration Protocol (DHCP) snooping, Dynamic Address Resolution Protocol (ARP) Inspection, and IP source guard
• Monitoring features such as Cisco NetFlow, packet statistics, Switched Port Analyzer (SPAN), and Encapsulated Remote SPAN (ERSPAN)
• Manageability features such as Simple Network Management Protocol (SNMP), NetConf, syslog, and advanced troubleshooting command-line interface (CLI) features
• Virtual services using Cisco vPath such as Cisco Virtual Security Gateway (VSG)
Virtualized Network Services with Cisco vPath
• Intelligent traffic steering
– Redirect traffic from the server requesting network service to the virtual services node (VSN).
– Extend the port profile to include the network services profile.
• Flexible deployment
– Each VSN can serve multiple physical servers.
– The VSN can be hosted on a separate or dedicated server.
• Network service acceleration
– Using network service decision caching, the Cisco Nexus 1000V remembers network service policy from prior traffic, reducing the need for traffic steering.
– The performance of virtual network services can be accelerated through enforcement in the hypervisor kernel.
Integration with Microsoft Hyper-V and SCVMM
Figure 2. Operating Model for Cisco Nexus 1000V Switch for Microsoft Hyper-V
Table 1. Cisco Integrated Security Features
• Cisco NX-OS, the OS run by the VSM, is specifically designed for high availability at the network, system, and process levels. Critical processes run independently for ease of isolation, fault containment, and upgrading. Processes can restart independently in milliseconds without losing state information, affecting data forwarding, or affecting adjacent devices or services.
• VSMs are typically deployed in active-standby pairs for high availability. The state and configuration remain constantly synchronized between the two VSMs to provide stateful switchover if the active VSM fails.
Maximum Supported Configurations
• 64 Microsoft Windows Server 2012 with Hyper-V hosts per VSM
• 2048 virtual Ethernet ports per VSM, with 216 virtual Ethernet ports per physical host
• 2048 active VLANs
• 2048 port profiles
• 32 physical NICs per physical host
• Microsoft Windows Server 2012 or later (Standard or Data Center)
• Microsoft SCVMM 2012 SP1 (UR2) or later
• Cisco Nexus 1000V VSM
– The VSM can be deployed as a virtual machine on Microsoft Windows Server 2012 with Hyper-V or on a Cisco Nexus 1110 appliance
– Hard disk: 4 GB
– RAM: 4 GB
• Compatible with any upstream physical switches, including all Cisco Nexus and Cisco Catalyst® switches as well as Ethernet switches from other vendors
