Connect a Nexus 2000 to two Nexus 5000 with different links

Heiko Kelling · ‎02-13-2013

Hi, is it possible to connect one Cisco Nexus 2000 fabric extender to two Cisco Nexus 5000 and use one link on the first side and two links on the other side?

If it is possible, can somebody tell me something about the load distribution in this scenario? Is it a 50:50 load balancing?

Thanks in advance!

I don't think you can do uneven connections to the 2ks. Because essentially you are creating a vPC to the FEX.

Hi,

I have this layout at the moment on the run and I have no problems. But there this time I have no connected servers. Only the configured Nexus infrastructure.

No idea?

Another question of me is, how the forwardings decision works if a fex is connected to two 5Ks? Which algorithm is used and how make the two 5K´s the decision about which 5K the packet is forwarded?
