I have a problem with Port-channel Uplink between Fabric Interconnect with N7K using vPC
This is my network topology for UCS Deployment
In N7K I has configured vPC for red link and green link, at Fabric Interconnect A I has configured Port-Channel with member is Port 1 and Port 2, uplink is red link. At Fabric Interconnect B, I has configured Port-Channel with member is Port 1 and Port 2, uplink is green link.
The show interface port-channel on N7K is good, every port-channel is up and have all member. But At Fabric Interconnnect, when I see on UCS Manager, the status of Port-Channel on Fabic A and Fabric B is fault with Additional Info: No operational member. Although all link is link up and I has status of Port-Channel is enable on UCS Manager. When I see the Properties of Port 1, Port 2 on Port-channel, I see the membership status is : individual. This mean port-channel is not up and no membership in this configuration. I want to using port-channel for load balance and plus more bandwidth for uplink to 20Gig. I don't understand why ?
Please help me resolve this problem, I has send the capture screen of UCS Manager when I show status of Port-channel and Port-member in port-channel in attach items.
Anyone can help me to resolve this, thanks you very much. Please reference attach items for more detail about fault.
Solved! Go to Solution.
Thanks Matthew very much,
I has resolved this problem. The reason of problem is miss match protocol of port-channel between N7K and Fabric Interconnect. The Fabric Interconnect always use LACP protocol, but N7K using Port-channel mode on, that why the port-channel failed. I has configured LACP for port-channel in N7K, it has resolved the problems.

Hi Dustin Nguyen,
My N7K not using 2248 as remote linecard, we are using 10Gbps Interface with N7K-M132XP-12 (32 Port 10G). I use 2 port 10G on each N7K to create vpc, total bandwidth is 20G. I will collect configuration and send for you as soon as possible.
Just adding my $0.02 based on a troubleshooting session:
If you have optical cabling between the FI and Nexus, check your polarity: it may need to be changed
Just did so for eight uplinks.
Hi Nguyen Duc Trung,
Can you share your N7K vPC configuration with UCS-M? If possible send me a PM or send me an email.- I would greatly
appreciate your input!
I has configured N7K vPC on customer site at one year ago , so now I must contact with customer to get this configuration, please waiting me, I will reply you soon.
P/S: Did you sent a add request my yahoo IM ?
