ABD should be better answer

The virtual port channel (vPC) feature was introduced on the Cisco Nexus 5000 Series platforms to provide two active paths, to eliminate the need to run the STP protocol, and to have Active-Active redundancy. vPCs are mainly used for servers that can do port channeling as well as connect to Cisco Nexus 2000 Fabric Extenders. vPCs are deployed in the CE domain. When you migrate to a FabricPath network, devices evolve from a vPC to a vPC+ design.
The vPC+ feature was introduced to allow interoperability between FabricPath and vPCs. The functionality and behavior of a vPC+ and a vPC is identical. The same rules apply in both technologies. That is, both require peer link and peer keepalive messages, the configurations must match between the vPC peers, and consistency checks still take place. In a vPC+ domain, a unique FabricPath switch ID is configured and the peer link is configured as a FabricPath core port. This FabricPath switch ID under the vPC+ domain is called the Emulated switch ID. The Emulated switch ID must be the same between the two peers and must be unique per vPC+.

This example shows how to display the FabricPath device ID table. A device’s switch ID is shown in addition to the emulated switch ID. The same system ID is displayed twice for each device: one is associated with the switch ID and one is associated with the emulated switch ID.

FabricPath Switch IDs
When FabricPath is enabled globally, each device is atomatically assigned with a switch ID (12 bits) You have the option to manually configure the switch ID, but you must ensure all devices in the FabricPath domain have unique values. The switch ID is encoded in the outer MAC addresses of the FabricPath MAC-in-MAC frames.
The Dynamic Resource Allocation Protocol (DRAP) automatically assigns a switch ID and ensures that no duplicate IDs exist in the FabricPath domain. The FabricPath network automatically detects conflicting switch IDs and prevents the data path initialization on the FabricPath interface. As a best practice, we recommend that you manually set the switch IDs.
The emulated switch ID is used in a VPC+ to identify the VPC+ bundle. The emulated switch ID must be unique within each VPC+ virtual switch domain. In a vPC+ domain, three switch ID’s will be used—one unique switch ID for each vPC peer and one emulated switch ID that is common between both vPC peers.

ABD should be answer. Manual switch ID is not must, it’s recommended. Switch ID is 12 bit number, much greater than 99. 2^12 = 4096, or between 0-4095
