Hello at all,
I try to establish a SMLT connection with LACP.
I do have two VSP-7400-48Y-8C VSPs and one Cisco UCS C240 server with 6 network interfaces (4 x 25GBit SFPs and 2x 10GBit RJ45 Ports).
On the server side I created a bond with one of the 25GBit ports and one 10GBit port (LACP 802.3ad).
On the VSPs I created a SMLT with LACP:
Connection 1 -> VSP1 (port 1/10) to server 25GBit port(SFP)
Connection 2 -> VSP2 (port 1/10) to server 10GBit port(RJ45)
But the SMLT will not work. I always got an error "GlobalRouter LACP INFO A churn condition has been detected for port 1/10 as the PARTNER is out of sync."
I got the error on both VSPs, depending which port do enable first.
In the VSP GUI inside the port/lacp tab the "ActorOperState" is "lacpActive,lacpShortTimeout,aggregation,synchronization" for one port an for the other one
"lacpActive,lacpShortTimeout,aggregation,synchronization,collecting".
I tried on two different servers and both are not working.
I also tried to setup an SMLT with LACP to two 25GBit ports - this is working fine.
What could be the problem?
Thank you so much.

Hello,

Hi,
For me, it's not possible to form a LACP bundle with two differents speed ports. It's by design not supported.
Regards.
