Enhanced vPC
Starting from release Cisco NX-OS 5.1(3)N1(1), you can create vPC teaming from servers to dual-homed fabric
extenders as depicted in Figure 38.
Figure 38. Enhanced vPC
Enhanced vPC requires the following hardware:
●
Cisco Nexus 5500 platform products (Cisco Nexus 5548P, Cisco Nexus 5548UP, and Cisco Nexus
5596UP)
●
Any fabric extender (Cisco Nexus 2148T or any Cisco Nexus 2200 platform)
FCoE with Fabric Extender Single-Attached to Cisco Nexus 5000 Series
The fabric extender straight-through topology supports FCoE in case the Cisco Nexus 2232PP is used.
Figure 39 illustrates this deployment. Servers 1 and 2 in the figure are equipped with FCoE Initialization Protocol
(FIP)-capable CNAs that, respectively, log into Fabric A and Fabric B. The FCoE configuration is no different than
the configuration when the servers are directly connected to the Cisco Nexus 5000 Series Switch.
For FCoE to work, the CNA can use only two physical ports as part of a vPC. These two ports are used by Fibre
Channel as two independent ports, and not as part of a PortChannel. Conversely, Ethernet traffic can be hashed
by the CNA onto the two physical links according to the PortChannel hashing configuration.
