Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) v1.2VirtualizationEasy
A network engineer is configuring a Cisco Nexus 1000V distributed virtual switch. Which component is responsible for providing the control plane functionality, centralizing management, and enabling advanced networking features across multiple hypervisors?
- AVirtual Supervisor Module (VSM)
- BVirtual Port Group (VPG)
- CFabric Extender (FEX)
- DVirtual Ethernet Module (VEM)
Show answer & explanationAnswer & explanation
Correct answer: A. Virtual Supervisor Module (VSM)
The Virtual Supervisor Module (VSM) in a Cisco Nexus 1000V acts as the control plane, centralizing the configuration and management of all associated Virtual Ethernet Modules (VEMs) across different hypervisors.
Why the other options are wrong
- B. VPGs are logical constructs for grouping ports with similar policies, not a control plane component.
- C. FEX is a physical hardware component used to extend the I/O of a parent switch, unrelated to the 1000V's control plane.
- D. VEMs are the data plane components residing on each hypervisor, forwarding traffic.
Cisco Nexus 1000V VSM
The Virtual Supervisor Module (VSM) is the control plane component of the Cisco Nexus 1000V distributed virtual switch. It runs as a virtual appliance and provides centralized management, configuration, and advanced networking features for all connected Virtual Ethernet Modules (VEMs) on hypervisors.
- Control plane for Nexus 1000V.
- Centralized management.
- Runs as a virtual appliance.
Memory trick: VSM is the Brain, VEMs are the Brawn.
