What Is The Vpc In Cisco
Cisco nx os software vpcs and cisco catalystvirtual switching systems vss are of similar technologies.
What is the vpc in cisco. Now let s get started. Before going into deep if you need help on basic vpc configuration you can check out how to configure cisco nexus vpc. In this lesson we will learn to configure double sided vpc back to back vpc.
Two switches of the same model can be combined into a vpc pair which can establish a single etherchannel also known as a link aggregate or a port channel across both switches to a third switch or server. The third device can be a cisco nexus 2000 series fabric extender or a switch server or any other networking device. At this time being vpc is implemented on cisco nexus 9000 7000 5000 and 3000 series platforms with or without cisco nexus 2000 series fabric extenders.
Vpc also allows the creation of layer 2 portchannels that span two switches. It is a cisco nexus specific protocol that is hard to configure on any other type of switch. Interesting to note that cisco state that in the future third party firewalls will take advantage of this.
Vpc is a virtualization technology that presents both cisco nexus 7000 series paired devices as a unique layer 2 logical node to access layer devices or endpoints. It allows an appliance to be logically connected to the switch s backplane. This type of vpc called double sided vpc or back to back vpc.
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. Of course there are indeed vpc enabled switches offered by other vendors except cisco such as fs n series switches. Vpc belongs to multichassis etherchannel mcec family of technology.
Cisco has recently announced a new protocol for the nexus 7000 remote integrated services engine rise. 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. Vpc or virtual port channel is a cisco proprietary feature available on the nexus platform.
