Cisco Nexus 1000V License Configuration Guide Release 4.0 PDF Manual
Cisco Nexus 1000V provides Layer 2 switching functions in a virtualized server environment. Cisco Nexus 1000V replaces virtual switches within ESX servers and allows users to configure and monitor the virtual switch using the Cisco NX-OS command line interface. Nexus 1000V also gives you visibility into the networking components of the ESX servers and access to the virtual switches within the network. 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 has the following components: Virtual Ethernet module (VEM)-data plane • Each hypervisor is embedded with one VEM. The VEM is a lightweight software component that effectively replaces the virtual switch by performing the following functions: – Advanced networking and security – Switching between directly attached virtual machines – Uplinking to the rest of the network Note A license is required for every CPU on a VEM. • Virtual supervisor module (VSM)-control plane The VSM is a standalone, external, physical or virtual appliance that performs the following functions for the Cisco Nexus 1000V system—that is, the combination of the VSM itself and all VEMs it controls: – Configuration – Management A single VSM can manage up to 64 VEMs
