What is vpc in nexus. vPC Member- vPC member use to which switch has participated the single vPC domain. The third device can be a switch, server, or any other networking device that supports port channels. This monitors the state of the vPC peer devices and periodically sends keepalives between them. This approach boosts redundancy, load balancing, and performance without relying on Spanning Tree Protocol. Virtual Port Channel (vPC) is a feature available for Nexus switches. 4 days ago · 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. Apr 1, 2025 · VPC is a Cisco Nexus terminology used to elevate the port-channel functionality to the next level. There are various components of the VPC and below diagram illustrates most of them – VPC Peer: These are the Dec 19, 2013 · vPC test scenario 2 Summary What can I say, Nexus product line is Cisco’s main switch for datacenter environment and features like vPC are essential for it. Jul 15, 2025 · A virtual port channel (vPC) allows links that are physically connected to two different Cisco Nexus 9000 Series devices to appear as a single port channel to a third device. Mar 12, 2022 · vPC (Virtual Port Channel) is a Layer 2 technology used in Cisco Nexus Switch that enables the device to appear as a single logical device for the end host. In this lesson, we will learn how to configure Cisco Nexus vPC. A virtual port channel (vPC) allows links that are physically connected to two different Cisco Nexus 7000 or 9000 Series devices to appear as a single port channel by a third device. It is an advanced version of VSS technology. . 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 vPC peer link is the key to allowing the Nexus switches to synchronize control-plane information and maintain a consistent view of the network. Nexus family of switches supporting this technology are 9K, 7K, 5K and 3K. A Port-Channel is a technology that provides a way to aggregate (bond) multiple interfaces together. Jun 7, 2025 · The Virtual Port-Channel (vPC) feature available on Cisco Nexus switches allows you to connect a single device to two separate switches while forming a logical Port-Channel. Some of the keywords we have used as shown in topology, we will know in detail about vPC members, vPC Peer-Keepalive, vPC peer-link, and other concepts. Dec 5, 2024 · Since the inception of Cisco NX-OS on Cisco Nexus data center switches, the Virtual Port Channel (vPC) feature has received numerous enhancements that improve the reliability of vPC-connected devices during failure scenarios and optimize forwarding behavior of both vPC peer switches. Dec 19, 2019 · What is a Port-Channel? Before we dive into vPC it is important to quickly review Port-Channels. Oct 14, 2021 · As vPC (Virtual Port Channel) this is used to configure two nexus switches logically single for the end device. Traffic is then loadbalanced across each of the connections. Port-Channels provide 3 key benefits, * Redundancy - Should one of Oct 27, 2021 · N9K (config-vpc-domain)# peer-gateway vPC Orphan Ports vPC orphan port is the which ports are not the part of vPC, those port known as orphan ports. If you want to know details, then check fundamental concepts of vPC by Cisco. For example, if any servers have single connectivity with only Nexus-1 switch so we cannot configure the vPC on single end-host connectivity this port will be an orphan port. What however I really miss on Nexus is the virtualization technology like HP IRF (which is actually much more powerful then vPC). Secondly, a vPC keepalive link must be established between the Nexus switches. Using EtherChannel links, you can interconnect two Nexus switches that are running the vPC feature and configuration. In VPC the links connected to two separate physical devices can be bundled together to form an ether-channel. flhmj szh fnajj gprd aaenad nfi igrrkd lkrnzup ivxaroetg ofykel
