Does Nexus 7K support vPC?

The same type of Cisco Nexus switches must be used for vPC pairing. It is not possible to configure vPC on a pair of switches consisting of a Nexus 7000 series and a Nexus 5000 series switch. vPC is not possible between a Nexus 5000 and Nexus 5500 switches.

How does vPC work in Nexus?

Virtual Port Channel (VPC) ties two Nexus 7K or 5K switches together by doing a great job of spoofing Layer 2 (L2), including STP BPDU (Spanning Tree hellos) and FHRP (First Hop Routing Protocol — HSRP, VRRP, GLBP) behavior. In terms of the diagram below, you can add the port-channel to switch C.

Does Cisco vPC require LACP?

Question 1: “is LACP mandatory for vPC?” – No.

Which protocol is used by vPC peers to synchronize control plane information?

the Cisco Fabric Services protocol
The vPC peers use the Cisco Fabric Services protocol to synchronize forwarding-plane information and implement necessary configuration checks or both.

What is Nexus vPC and what are its benefits?

What is vPC? 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 peers). vPC is similar to Virtual Switch System (VSS) on the Catalyst 6500s.

How do I check my vPC configuration?

To verify vPCs using the CLI, perform one of these tasks:

1. Purpose. Command.
2. show running-config vpc. Checks the status of the vPCs.
3. show vpc peer-keepalive. Verifies that the vPC peers have the identical type-1 parameters.
4. show vpc consistency-parameters.
5. show tech-support vpc.
6. show port-channel summary.

What happens if vPC peer link goes down?

vPC peer-link failure If peer-link fails, then all the member ports from vPC secondary node will be suspended. Here important to note, keep-alive is active in this scenario, which allowing nodes to exchange heartbeat.

What is the purpose of vPC?

A virtual private cloud (VPC) is an on-demand configurable pool of shared resources allocated within a public cloud environment, providing a certain level of isolation between the different organizations (denoted as users hereafter) using the resources.

What is vPC and LACP?

Hello, lacp is just a negotiation protocol for bundling links from the same physical/logical switch to another host or switch. Vpc is a technology whereby it allows you to have two separate switches, providing one bundle to a switch or host.

What happens if vPC peer-link goes down?

What is primary and secondary vPC?

Primary and Secondary Roles One vPC peer holds the primary role, and the other holds the secondary. By default, only the primary switch responds to control plane traffic. For example, when traffic such as an ARP request is sent to the domain, the primary switch responds.
