Virtual PortChannel Connection

vPCs allow links that are physically connected to two different Cisco Nexus switches to form a PortChannel to a

downstream device. The downstream device can be a switch, a server, or any other networking device that

supports IEEE 802.3ad PortChannels. vPC technology enables networks to be designed with multiple links for

redundancy while also allowing those links to connect to different endpoints for added resiliency (Figure 3).

More information about vPC technology can be found at

http://www.cisco.com/en/US/products/ps9670/products_implementation_design_guides_list.html

.

Blade Server Configuration Options

Configuring a vPC

Enable vPC (this configuration should be implemented on both switches in parallel):

1. Enable the vPC feature

2. Create the vPC domain

3. Configure the peer keepalive link

4. Configure the vPC peer link PortChannel

5. Check the status of vPC

1. Enable the vPC feature.
