What is the difference between VSS and VPC on a switch?
Correct, VSS is only for Catalyst series switches and vPC is for the Nexus switches which are mainly designed to be used in data centers. As for as connecting the Cisco to Dell and other vendors, you can use LACP for bundling multiple uplinks in one logical connection. LACP is standard and used pretty much by all vendors.
What is the difference between VPC and Nexus?
Nexus is mainly used for data center and VSS for campus environment. The max number of devices you can use for both VPC and VSS is 2. 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.
What is the difference between a 6500 and a VPC?
VSS is the 6500 technology to logically combine two physically separate chassis. As you point out vPC is a Nexus technology, the Catalyst equivalent is MEC (Multi-chassis Ether Channel). From your message you are correct in thinking that using etherchannel from the TOR switches to the core is the correct solution.
What is the catalyst equivalent of VPC?
As you point out vPC is a Nexus technology, the Catalyst equivalent is MEC (Multi-chassis Ether Channel). From your message you are correct in thinking that using etherchannel from the TOR switches to the core is the correct solution.

What is a vPC on Nexus?
vPC's, or Virtual Port Channels, are a Cisco Nexus technology. They are used to connect layer-2 devices to two switches at once. This makes it possible to create a highly available environment in the data centre. If one switch fails, the other one continues to operate.
What is the difference between VSS and stacking?
Functionality wise, there is no difference. Stackwise Virtual and VSS are technically the same. They are called what they are because of marketing. In both instances, two physical chassis for a single logical unit which makes management easier and enables cross-chassis Etherchannel.
What is the difference between vPC and port channel?
Here you can see that Virtual Port channel (vPC) is configured using the interfaces of two switches. One of the key difference between the two technologies (port-channel and virtual port-channel ) is that port channels support both Layer 2 and Layer 3. vPC on the other hand only supports Layer 2.
What is the purpose of vPC?
Amazon VPC enables you to build a virtual network in the AWS cloud - no VPNs, hardware, or physical datacenters required. You can define your own network space, and control how your network and the Amazon EC2 resources inside your network are exposed to the Internet.
What is vPC in Nexus and what are the benefits?
VPC is a feature available for Nexus switches. You can bundle links from two different switches that are running the vpc feature and config. It helps with doubling the bandwidth and creates a loop free topology (from STP perspective). VSS does the same thing for IOS switches using MEC.
How many control planes are there in VSS?
one Control planeIn Virtual Switch Mode, while only one Control plane is active, both Data Planes (Switch Fabric's) are active, and as such, each can actively participate in the forwarding of data …
How does Cisco VSS work?
A VSS is network system virtualization technology that pools multiple Cisco Catalyst Switches into one virtual switch, increasing operational efficiency, boosting non-stop communications, and scaling system bandwidth capacity.
What is VSS in vmware?
VSS detects which VMs are logically connected to which virtual ports and uses that information to forward traffic to the correct VMs -- it emulates a physical hardware switch. VSS comes free with an ESXi installation and you can create several vSSes on each ESXi host.
How many vPC domains can a switch have?
The maximum number of switches in a vPC domain is two. The maximum number of vPC peers per switch or VDC is one. When Static routing from a device to vPC peer switches with next hop, FHRP virtual IP is supported. Dynamic routing adjacency from vPC peer switches to any Layer3 device connected on a vPC is not supported.
Is vPC active active?
In data plane terms, HSRP with vPC is active/active. Both of the switches forward traffic.
Is LACP and port channel the same thing?
The Link Aggregation Control Protocol (LACP), described by IEEE 802.3ad, defines a method for two switches to automatically establish and maintain link aggregation groups (LAGs, also called channel groups or port channels). Using LACP, a switch can configure LACP-compatible ports into a dynamic LAG.

How many switches are managed in VSS?
6) In VSS, only one logical switch has be managed from management and configuration point of view.That means, when the switches are put into VSS, now there is only one IP which is used to access the switch. They are not managed as separate switches and all configuration are done on active switch.

Is VSS only for Cisco?
Correct, VSS is only for Catalyst series switches and vPC is for the Nexus switches which are mainly designed to be used in data centers. As for as connecting the Cisco to Dell and other vendors, you can use LACP for bundling multiple uplinks in one logical connection. LACP is standard and used pretty much by all vendors. As for which switch to use, read the datasheets for multiple platforms and compare to make sure the switch meets your requirement before purchasing.
Can a port channel be used for multiple switches?
Both are used basically to support multi-chassis ether-channel that means we can create a port-channel whose one end is device A,however, another end is physically connected to 2 different physical switches which logically appears to be one switch.
