Components
Cisco Nexus™ 1000V consists of two parts
• VSM – Virtual Supervisor Module

– Configuration is performed through the VSM and is automatically propagated
to the VEMs.
– One VSM can manage up to 64 VEMs
– Cisco recommends having two VSMs configured as a pair to act as a two SUP
switch
• VEM – Virtual Ethernet Module
