What Is A Vpc Nexus
They then appear as one layer 2 switch to the downstream device.
What is a vpc nexus. Peering traffic will traverse the vpc peer link. The third device can be a cisco nexus 2000 series fabric extender or a switch server or any other networking device. Vpc is similar to virtual switch system vss on the catalyst 6500s.
In this topology cisco recommends using the peer gateway command. With vpc we can make two nexus devices peers. Virtual port channel vpc typically used for providing active active connection from switch to end point devices.
Cisco v irtual p ort c hannel vpc is a virtualization technology launched in 2009 which allows links that are physically connected to two different cisco nexus series devices to appear as a single port channel to a third endpoint. Vpc virtual port channel also known as multichassis etherchannel mec is a feature on the cisco nexus switches that provides the ability to configure a port channel across multiple switches i e. Other platforms do not support the exact topology above.
It operates inside the vmware esx hypervisor and utilizes the nx os software. Cisco vpc aka virtual port channel which was launched in 2009 is a feature on the cisco nexus series switches that allows end device to configure a port channel across multiple switches. The result is that a downstream device like a switch or a server can have a two or more port port channel which happens to spread over both of those upstream peers.
However due to it provide loop free design we can configure one vpc domain on aggregation switches to other vpc domain on access switches while it providing more bandwidth for access switches to aggregation switches. Single sided vpc in single sided vpc access devices are connected to nexus 7k series devices using vpc domain the access device which is attaching to vpc domain can be of any device such as layer 2 switch rack mount server blade server firewall load balancer or any network attached storage nas device. If the vpc switches are nexus 3500 s 5000 s or 6000 s the topology above is fine.
In this lesson we will learn how to configure cisco nexus vpc. If you want to know details then check fundamental concepts of vpc by cisco. A virtual portchannel vpc allows links that are physically connected to two different cisco nexus 5000 series devices to appear as a single portchannel to a third device.
