Viewing vPC Configuration
The following commands can be launched from the inventory by right-clicking VPC Domain and
choosing Commands > Show. The table below lists vPC show commands.
Additional commands may be available for your devices. New commands are often provided in Prime
Network Device Packages, which can be downloaded from the Prime Network software download site.
For more information on how to download and install DPs and enable new commands, see the
information on “Adding Additional Device (VNE) support” in the Cisco Prime Network 4.0
Administrator Guide.
Before executing any commands, you can preview them and view the results. If desired, you can also
schedule the commands. To find out if a device supports these commands, see the Cisco Prime Network
4.0 Supported Cisco VNEs.
Note You might be prompted to enter your device access credentials while executing a command. Once you
have entered them, these credentials will be used for every subsequent execution of a command in the
same GUI client session. If you want to change the credentials, click Edit Credentials. The Edit
Credentials button will not be available for SNMP commands or if the command is scheduled for a later
time.
Cisco FabricPath
Cisco FabricPath is an innovation in Cisco NX-OS software that brings the stability and scalability of
routing to Layer 2. It provides a foundation to build a scalable fabric—a network that itself looks like a
single virtual switch from the perspective of its users. The switched domain does not have to be
segmented anymore, providing data center–wide workload mobility. Because traffic is no longer
forwarded along a spanning tree, the bisectional bandwidth of the network is not limited, and massive
scalability is possible.
Cisco FabricPath introduces an entirely new Layer 2 data plane by encapsulating the frames entering the
fabric with a header that consists of routable source and destination addresses. These addresses are the
address of the switch on which the frame was received and the address of the destination switch to which
the frame is heading. From there, the frame is routed until it is reaches the remote switch, where it is
de-encapsulated and delivered in its original Ethernet format.
