Viewing a vPC

The virtual port channel (vPC) feature enables you to view the links that are physically connected to different devices as a single port channel. A vPC is an extended form of a port channel which allows you to create redundancy and increase bisectional bandwidth by enabling multiple parallel paths between nodes and allowing load balancing traffic. Traffic is distributed among two single device vPC end points. If there is an inconsistency in the vPC configurations, the vPC does not function correctly.

The Cisco DCNM Web Client helps you to identify the inconsistent vPCs and resolve the inconsistencies in each vPC or in all vPCs.

Note The vPC inconsistency page displays inconsistencies only for the devices that have required Cisco DCNM licenses installed on them. The devices that do not have Cisco DCNM LAN license installed on them do not appear on this page.

Table 1-1 displays the following vPC configuration details in the data grid view.
