What is vPC and how it works?

A virtual private cloud (VPC) is a virtual network dedicated to your AWS account. It is logically isolated from other virtual networks in the AWS Cloud. … You can specify an IP address range for the VPC, add subnets, associate security groups, and configure route tables. A subnet is a range of IP addresses in your VPC.

What is the benefit of VSS?

VSS offers superior benefits compared to traditional Layer 2/Layer 3 network design. Benefits can be grouped into four main categories: 1. VSS increases operational efficiency by simplifying the network, reducing switch management overhead by at least 50 percent.

What is vPC peer switch?

When a Virtual Port Channel (vPC) is configured and operational, the Spanning Tree Protocol (STP) continues running on both vPC peer devices. The vPC peer switch is introduced to address performance concerns around these STP convergence events.

What is difference between VSS and vPC?

2) In VSS there will be single control plane for both the switches, where as in vPC there will be separate control plane for every switch. 3) VSS can support L3 port-channels across multiple chassis,however, vpc is used for L2 port-channels only.

How do I change my vPC domain ID?

The best way to change the vPC domain ID is to configure a new vpc domain command on both vPC peers. This solution is superior to the removal of the whole vPC configuration and the reapplication of it with the new vPC domain ID.

What is the port channel?

A port channel is an aggregation of multiple physical interfaces that creates a logical interface. You can bundle up to eight individual active links into a port channel to provide increased bandwidth and redundancy. Port channeling also load balances traffic across these physical interfaces.
