What is vPC in Cisco?
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.
Does Nexus 7K support vPC?
The same type of Cisco Nexus switches must be used for vPC pairing. It is not possible to configure vPC on a pair of switches consisting of a Nexus 7000 series and a Nexus 5000 series switch. vPC is not possible between a Nexus 5000 and Nexus 5500 switches.
What is Cisco enhanced vPC?
Enhanced vPC enables you to support server connectivity with one topology and address requirement for both high availability and high bandwidth. Without an Enhanced vPC server, you cannot connect port channels to FEXs when the FEXs are dual-homed to both Cisco Nexus 5500 Series devices.
What is Cisco FabricPath?
Cisco® FabricPath is an innovation in Cisco NX-OS Software that brings the stability and scalability of routing to Layer 2. Cisco FabricPath introduces an entirely new Layer 2 data plane by encapsulating the frames entering the fabric with a header that consists of routable source and destination addresses.
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.
What is the benefit of VPC?
A VPC gives users full control over the network size along with automation to scale resources up or down whenever required. These resources can be scaled dynamically in real-time.
What happens if vPC peer link fails?
vPC peer-link failure If peer-link fails, then all the member ports from vPC secondary node will be suspended. Here important to note, keep-alive is active in this scenario, which allowing nodes to exchange heartbeat.
What is vPC plus?
vPC+ is an extension to traditional vPC. It connects Classical Ethernet devices to a Fabricpath domain. Have a look at the diagrams below. vPC+ uses a pair of physical switches, like regular vPC does. vPC+ is different, as it creates a virtual switch.
What is extended vPC?
Enhanced vPC is a method that allows the connection of FEX in an active-active manner using vPC between the FEX and upstream Nexus switch, and at the same time connection of a device to the FEX host interfaces with a vPC.
What is Cisco OTV?
Overlay transport virtualization (OTV) is a Cisco proprietary protocol for relaying layer 2 communications between layer 3 computer networks.
What is difference between VSS and VPC?
3) VSS can support L3 port-channels across multiple chassis,however, vpc is used for L2 port-channels only. 4) VSS supports both PAgP and LACP,however, VPC only supports LACP. 5) VSS mainly used for campus environment whereas VPC is used for Data Center environment.
