Supported Vpc Topologies; Cisco Nexus 5000 Series Switch Vpc Topology - Cisco Nexus 5000 Series Configuration Manual

Supported vPC Topologies

• Host interface—An Ethernet interface for server or host connectivity. These ports are 1-Gigabit Ethernet
• EtherChannel host interface—An EtherChannel downlink connection from the Fabric Extender host
For further information about the Fabric Extender, refer to the Cisco Nexus 2000 Series Fabric Extender
Software Configuration Guide.

Cisco Nexus 5000 Series Switch vPC Topology

You can connect a pair of Cisco Nexus 5000 Series switches or a pair of Cisco Nexus 5500 Series switches
in a vPC directly to another switch or to a server. vPC peer switches must be of the same type, for example,
you can connect a pair of Nexus 5000 series switches or a pair of Nexus 5500 Series switches but you cannot
connect a Nexus 5000 Series switch to a Nexus 5500 Series switch in a vPC topology. Up to 8 interfaces
could be connected to each Cisco Nexus 5000 Series switch providing 16 interfaces bundled for the vPC pair.
The topology that is shown in the following figure provides the vPC functionality to dual connected switches
or servers with 10-Gigabit or 1-Gigabit Ethernet uplink interfaces.

Note
are switchable 1-Gigabit and 10-Gigabit ports. You can enable vPC functionality on these ports in 1-Gigabit
mode.
The switch connected to the pair of Cisco Nexus 5000 Series switches can be any standards-based Ethernet
switch. Common environments to use this configuration include Blade Chassis with dual switches connected
