What Is Vpc In Nexus 7000
Have you wondered how does vpc work this video is for you vpc is a way of adding layer 2 resiliency to the data centre this video explains vpc by examin.
What is vpc in nexus 7000. The third device can be a switch server or any other networking device that supports port channels. The third device can be a switch server or any other networking device that supports port channels. In this scenario vpc will not come up even for the nexus 7000 which is already up.
A virtual port channel vpc allows links that are physically connected to two different cisco nexus 7000 series devices to appear as a single port channel by a third device see figure 6 1. A virtual port channel vpc allows links that are physically connected to two different cisco nexus 7000 series devices to appear as a single port channel by a third device. Vpc belongs to multichassis etherchannel mcec family of technology.
In particular each vdc for the nexus 7000 series switches requires its own vpc peer and keepalive links and cannot be shared among the vdcs. Sometimes only one of the peers can be restored. In addition the n7k supports fairly robust and established technologies for multi dc interconnect dci such as otv and lisp.
Why do we need vpc auto recovery. Vpc auto recovery feature in nexus 7000. If there is a data center outage or power outage both vpc peers consisting of nexus 7000 switches are down.
Since the other nexus 7000 is still down vpc peer link as well as vpc peer keepalive link are also down. Support for fex virtual port channel vpc vdc mpls and fabricpath. Occasionally only one of the peers can be restored.
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. Vpc is similar to virtual switch system vss on the catalyst 6500s. 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.
