What is Cisco VSL?

What is Cisco VSL?

VSL is used to carry on proprietary encapsulated frames also control plane messages to form a single device, one supervisor the active one controls both chassis with second supervisor acting as hot standby as in a single chassis with two supervisors.

Is Cisco StackWise virtual the same as VSS?

Well, StackWise is on Catalyst switch platforms, including the Catalyst 3750, 3850, and 9000. That is similar to the next option, which is VSS, the Virtual Switching System. It is supported on the Catalyst 4500 and 6500 switch families.

What is the difference between VSS and VPC?

3) VSS can support L3 port-channels across multiple chassis,however, vpc is used for L2 port-channels only. 5) VSS mainly used for campus environment whereas VPC is used for Data Center environment. 6) In VSS, only one logical switch has be managed from management and configuration point of view.

What is the difference between StackWise and StackWise virtual?

What is the difference between StackWise-480 and StackWise Virtual? The existing StackWise technology significantly streamlines the access or distribution layer using high-speed back-panel StackWise ports and cables. The new StackWise Virtual increases switch stack function over the network ports and cables.

How do you verify VSS?

To check the VSS provider/writer status.

1. Open a command window.
2. At the command prompt, type vssadmin list providers, and then press ENTER.
3. Confirm that Microsoft VSS provider is listed as:
4. Type vssadmin list writers at the command prompt, and then press ENTER.
5. Confirm that all the VSS writers are showing:

What is VSS in Cisco?

Introduction. The Cisco Catalyst 6500 Series Virtual Switching System (VSS) allows the clustering of two or more physical chassis together into a single, logical entity. This technology allows for enhancements in all areas of network design, including high availability, scalability, management, and maintenance.

What is a VSS in Cisco 4500 series?

01-24-2013 01:11 PM The Cisco Virtual Switching System is a clustering technology that pools two Cisco Catalyst 4500-E Series Switches with Cisco Catalyst Supervisor Engine 7-E or 7-LE or two Catalyst 4500-X Series Switches into a single virtual switch. In a VSS, the data plane of both clustered switches is active at the same time in both chassis.

How to replace VSS switch in Catalyst 4500?

Configure 1 Identify Switch Roles. The first step is to identify the switch that must be replaced. 2 Failover. Now, you understand which switch is active (Switch 1) and which switch is in the standby state (Switch 2). 3 Verify failover. 4 Switch Removal. 5 Stage and Install the Replacement Switch. 6 Configure and Join the VSS.

How many etherchannels are needed for the VSL?

Because the VSL requires two EtherChannel numbers (one for each switch in the VSS), there are 254 user-configurable EtherChannels. Note Cisco Release IOS XE 3.4.0SG does not support Layer 3 MEC. Figure 5-4 VSS with MEC

What to do when VSL is down on Cisco switch?

In order to verify that you are back in stateful switchover (SSO), or the hot standby state, enter another show redundancy command. If the VSL remains down while one or both of the switches finish booting, you might enter a dual active situation if there is no dual active detection mechanism in place.
