HyperFlex Replication Network Config Failure

[Networker_eg]

I have replication Network config failure on 2 clusters

Cluster-1: Failed to post the Replication Network job

HX does not even touch UCSM or Vcenter , I am using HXDP 35.(2d)

Cluster-2: [137] : Configure Bandwidth on Nodes - Failure: Error: Failed to set replication DstQosBW - Error Message Replication 23000

HXDP : 3.5(2d)

Vcenter : 6.5U2

UCSM : 4.0()

Now this error is generated during replication configuration and config fail

Have anyone seen this before

Has either cluster been expanded prior to trying to establish the replication?

Thanks,

Kirk...

DC-1 : expanded with 8 compute-only node clusters 

DC-2 : expenses with 3 compute-only 

node clusters

is there any other way of adding compute-only node to the cluster ?

We also received this error.  We were able to get around this error with just checking the box for override the MTU size and set it to 1500.  The documentation states the MTU for the replication traffic should be 1500, but we received the same error unless we hard set it here to 1500.
