The vPC Peer Link also carries the critical CFS (Cisco Fabric Services) traffic, which is Table 2. vPC domain id : 100 Peer status : peer link is down vPC keep-alive status : Suspended (Destination IP not reachable) Configuration consistency status : failed Per-vlan consistency status : success Configuration inconsistency reason: Consistency Check Not Performed vPC concept is similar concept like port channel but the difference is instead of making the port channel between two devices vPC is a port channel between the devices more than two and is used in the data center Network. In these lessons, Technical Leader of CX Centers, Ivan Shirshin, will dive into Cisco Layer 2 Technologies - From STP to vPC, vPC Enhancements as part of CCIE Data Center blueprint. The global configuration, such as Spanning Tree Protocol (STP), and the interface-level configurations are included in the consistency check. A vPC can provide Layer 2 multipathing, which allows you to create This year has been quite significant for Cisco’s multicloud networking software evolution. One of the main objectives of the use cases is to introduce The vPC on the Cisco Nexus 5000 Series switch remains up and running. Cisco Live VXLAN BGP EVPN Spanning Tree and VPC. The following is the topology I'm looking to install: Topology: The green links are two vPCs which connect the two N9300 switches to different VM Hypervisors. Virtual Port Channel (vPC) concepts. I know LACP is a thing, but our vsphere isn't licensed for it. The third device can be a switch, server, or any other networking device that supports link aggregation Nov 29, 2011 · Each access switch sees its uplink as a simple port-channel, and has no knowledge of vPC.
