How does Cisco VSS work?
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 the difference between port channel and vPC?
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 Cisco VSS and 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.
How many control planes are there in VSS?
one Control plane
In 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 vPC work?
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.
What is VSS vPC?
Introduction to VPC and VSS Both VPC and VSS 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.
What is the purpose of vPC?
Amazon Virtual Private Cloud (Amazon VPC) gives you full control over your virtual networking environment, including resource placement, connectivity, and security. Get started by setting up your VPC in the AWS service console.
What is vPC in Cisco?
vPC (Virtual Port Channel) is the Cisco Proprietary feature that is only working on Cisco Nexus Components. vPC use to make Nexus devices logically single devices for the end host or devices. vPC is also known as Multi-chassis EtherChannel (MEC).
What is SSO in VSS?
Short answer. SSO = Stateful switchover , establish a relation of active / passive between 2 supervisor engines in a chassis to provide uninterrupted L2 functionality in case of a hardware failure.
Why vPC is used?
Q: Why should I use Amazon 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.
How does vPC work Cisco?
Cisco virtual Port Channel (vPC) is a virtualization technology, launched in 2009, which allows links that are physically connected to two different Cisco Nexus Series devices to appear as a single port channel to a third endpoint.
How does VPC work Cisco?
What is VPC in Cisco?
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, add gateways, and associate security groups. A subnet is a range of IP addresses in your VPC.
What is MEC in VSS?
Multichassis EtherChannel (MEC) is very similar to cross-stack EtherChannel in principle. The difference is that the feature known as MEC is found on the Catalyst 6500 VSS switches. VSS is a clustering technology that allows multiple 6500 chassis to be configured as a single logical switch.
What is LMP & RRP?
LMP verifies link integrity, rejects unidirectional links, and establishes bidirectional communication between switch chassis. 4. LMP exchanges switch IDs in order to detect duplicate IDs. 5. RRP checks hardware versions, software versions, and VSL configurations for compatibility.
How does Cisco VPC work?
What is VPC in Cisco switch?
What is the difference between VSS and VPC?
The big functional difference, VSS behaves as one logical device (although it avoids moving traffic ti/from its peer) while VPC operates as two logical devices except for the VPC port-channel. Further, VSS, has IAs on 6xxxx platforms (I recall the technology is being dropped), and VPC offers fabric extensions devices.
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. I am not clear on why you want vPC/ MEC…are you planning on deploying a large core switch at each remote site??
How does the VPC peer switch work?
When the vPC Peer Switch feature is enabled through the peer-switch vPC domain configuration command, both vPC peers will begin operating as root bridges of the Spanning Tree domain. Both vPC peers will begin originating identical Spanning Tree BPDUs asserting themselves as the root bridge of the Spanning Tree domain.
How often do VPC peers generate SysLogs after the routing enhancement is enabled?
After the Routing/Layer 3 over vPC enhancement is enabled, both vPC peers will begin generating syslogs similar to one of the following once every hour: 2021 May 26 19:13:47.079 switch %VPC-2-L3_VPC_UNEQUAL_WEIGHT: Layer3 peer-router is enabled.
