What Is Cisco Vss?

Cisco Virtual Switching System (VSS) is a technology that allows two Cisco Catalyst switches to work together to create a single, virtual switch. This virtual switch appears as a single entity in the network, but in reality, it is made up of two separate switches that are connected together.

The main advantage of Cisco VSS is that it provides improved network availability and performance. By using two switches, one as a primary and one as a secondary, the network can continue to operate even if one of the switches fails. In addition, the use of a single, virtual switch can improve network performance by allowing traffic to be evenly distributed across both switches.

Cisco VSS is often used in large enterprise networks and data centers to provide high availability and performance. It is also commonly used in service provider networks to provide a scalable and flexible infrastructure.

To use Cisco VSS, both switches must be compatible and have the necessary hardware and software installed. The switches are then connected together using special cables and configured to work as a single virtual switch. Once configured, Cisco VSS allows network administrators to manage the virtual switch as a single entity, simplifying network management and maintenance.

What Is The Use Of Vss Switch?

VSS stands for Virtual Switching System. It is used to create one logical switch by combining two physical switches. It is a Cisco proprietary. This feature is supported on Catalyst 4500 & 6500 modular switches.

What Is The Difference Between Vss And Vpc?

As far as the difference, VSS has one control plane vs VPC 2 different ones. With VSS you eliminate the use of VRRP, HSRP, etc.. with VPC you still have to use one HSRP or VRRP. These platforms are built for different environments. Nexus is mainly used for data centers and VSS for campus environments.

How Does Vss Work?

Microsoft’s VSS operates by taking what is called a copy-on-write snapshot of your system. This allocates a small temporary storage space. Then, every time you write to a part of your disk, the information on the disk is first copied to the snapshot before allowing the write to take place.

Why Use Cisco VSS?

VSS eliminates the need for protocols like HSRP (Hot Standby Routing Protocol) or VRRP (Virtual Router Redundancy Protocol), which are generally put in place to help with redundancy. These protocols still require each switch to have its own control plane, which is where VSS is more optimal.

How To Configure VSS On Cisco Switch?

Configuration Steps

  1. STEP1: Assigning Virtual Switch Domain and Switch Numbers. First you have to configure the same virtual switch domain number on both switches of the VSS. …
  2. STEP2: Configuring VSL Port Channel. …
  3. STEP3: configure the VSL ports. …
