VpcApp Service

This chapter describes the DCNM web services' API methods for the VpcApp service.

Information About VpcApp Service

A virtual port channel (vPC) enables links that are physically connected to two different devices (VDCs) to be viewed as a single logical port channel by the third device that forms the port channel with the vPC devices. You can set up a vPC between Layer 2 port channels.

The vPC is the port channel extended across two different chassis. With a vPC, an access layer switch could have the links of the same port channel terminating in two different distribution layer devices.

The vPC peer-link is a special inter switch link (ISL) that connects two Cisco Nexus 7000 series chassis. This link transfers control and data traffic across the chassis. The operational and configuration parameters of each chassis are exchanged on this link. The link is typically a port channel because the peer-link needs to be redundant and have enough bandwidth to transfer data traffic.

APIs are grouped as the following categories:

1. Query and Get APIs—Query data from the persisted database.

2. Create API—Create new vPCs.

3. Modify API—Modify vPCs, and vPC device-level configurations.

4. Delete APIs—Delete existing vPCs.

5. Enable and Disable APIs—Enable or disable a peer-link on port channel interfaces.

6. Synchronize APIs—Synchronize a primary vPC device with a secondary vPC device.
