## 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.

This section contains the following:

• Viewing vPC Inconsistencies

• Resolving vPC Inconsistencies

From the menu bar, choose Health > Virtual Port Channels (vPC).

Cisco DCNM Web Client displays both the consistent and inconsistent 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.

Table 1-1 vPC Configuration Details

Column | Description
vPC ID | You can view all the multichassis vPC end points and corresponding peer switches for each vPC ID.
Domain ID | Domain ID of the vPC peer switches.
Multi-chassis vPC End Point - Device Name | Details of the corresponding to peer single chassis primary vPC end points.
Multi-chassis vPC End Point - Port Channel ID | Single port channel that is connected to two single chassis vPC end points.
Primary vPC Peer - Peer Port Channel | Details of the corresponding multichassis vPC end points.
Primary vPC Peer - Port Channel | Single port channel that is connected to two single chassis vPC end points.
Primary vPC Peer - Device Name | Hostname of the vPC peer switches.
Secondary vPC Peer - Peer Port Channel | Details that correspond to the peer single chassis secondary vPC end points.
Secondary vPC Peer -Port Channel | Secondary port channel that is connected to two single chassis vPC end points.
Secondary vPC Peer -Device Name | Secondary Hostname of the vPC peer switches.
