Configure ports on Nexus 5000/2000 for server nic teaming

[saratretbar]

Hi,

I have two Nexus 5000 and two Nexus 2000.  The 5000s are vpc peers.  I'd like to plug my server, with teamed nics, into a port on each 2000 and have them both be active.  Is this possible?  What are the steps?  I thought it should be this:

CPR_NEXUS_5K01(config)# int eth100/1/32

CPR_NEXUS_5K01(config-if)# channel-group 32

CPR_NEXUS_5K01(config)# int eth101/1/32

CPR_NEXUS_5K01(config-if)# channel-group 32

on both Nexus devices.

Hi,

Most servers support LACP

channel-group 32 mode active

You also need to create the portchannel.

interface port-channel 32

What is the topology?

1. N5K-1 to N2K-1 and N5K-2 to N2K-2 directly?

2. N2K-1 is vPC back to both N5Ks and N2K-2 is vPC back to both N5Ks?

Please post the topology first since the answer is depending on how they are connected.

if you are looking to multihome the the server ports to a vPC N2K up to N5K as the bellow diagram is not supported yet !! i am not sure but i think it i will be supported in new releases !

i think Jerry can confirm as well

while the bellow one is supported

The 5Ks are connected to each other and to both 2Ks.  Yes, I would like to multihome the server.  The server has two nics.  Does that mean I have the choice of plugging one nic into each of the 2Ks for fault tollerance or plugging both into a single 2K for additional speed? 

Thanks for the help,

Sara

Yes, it looks like your scenario is supported.

• Cisco Nexus 2000 Series Fabric Extenders  dual-connected to two upstream Cisco Nexus 5000 Series Switches (vPC):  In this deployment scenario, access-layer redundancy is achieved through  a combination of Cisco Nexus 2000 Series Fabric Extenders  dual-connected to an upstream parent switch and server NIC teaming.

I am assuming it meants NIC teaming to two 2000 series devices.

Have a look at figure-3 in this document:

From your description

The 5Ks are connected to each other and to both 2Ks.  Yes, I would like to multihome the server.  The server has two nics. 

it sounds like it is the first diagram in marwanshawi's post

then the answer is no. You cannot have active/active server NICs in with this design right now. The reason is Cisco doesn't support two layer vPC as of now. It will be supported in the later release.

If they are connected like

then the answer is yes, you can have active/active server NICs.

Hi Jerry and Marwan,

is the first diagram of the dual vpc is now valid or still not supported

Ucs to dual homed to 2 N2k which is dual homed to 2 N5k

Here is the detailed document about how to do teaming. It works great

Do you have a document with 9k/2k vpc nic teaming with with Linux red hat 7.4?
