Hi,
I am needing a little assistance in verifying a configuration of connecting an HP chassis w/3120 blade chassis to a pair of Nexus 5Ks. We ran into a very unusual issue with a certain chassis and I want to make sure my configuration is right. On the blade chassis, I have 4 x 1Gig uplinks channeled together. 2 uplinks go to one Nexus and 2 go to the other. Their config is as follows. I need someone to look at the configuration of the ports below and verify that #1 it is correct, and second, if its not, what am I missing in the configuration.
Thanks,
Greg

Hi,
Your configuration is correct. Is there a reason you are not using the same Portchannel ID on both sides?
Al though, it works fine when you use a different number on each side, but for simplicity, I would make them the same and also use the same id for vPC too.
You really don't need this command
channel-protocol lacp
as LACP will manage the channels.
Also, you already have vPC running between the 5ks right?

Thanks for the verification. I have several blade chassis and use port channel 11 as the uplink to the network on all of them.
vPC is running between the 5ks.
The issue I had run into was servers not being able to ping each other even though they were on the sam vlan. Also, some servers could ping each other but couldn't connect to a service, like SQL, on another server.

Hey I know it has been a long time. But do you remember if you ever resolved this issue and what the issue was? I am struggling with the same thing.
