Reasons to Avoid vPC in Datacenters

With Cisco Virtual Port-Channel (vPC), two Cisco Nexus switches can appear as one logical switch to a downstream device that is connected to it. When vPC multi-chassis link aggregation is implemented, Spanning Tree Protocol (STP) does not block any links. In turn, this results in a significant increase in network bandwidth and availability.

Advantages of Using vPC:

– Access to multiple paths
– Improved bandwidth
– Simpler architecture
– Easy to migrate

Disadvantages of vPC:

– Complicated configurations
– Problems with compatibility
– The consistency of VLANs
– Overlap of subnets is not permitted
– Layer 2 Loops
– Scalability issues
