Hi all,
I'm using qperf to compare TCP & RDMARC performance.
qperf report that it failed to modify the QP to RTR status.
Does anyone know how to solve the problem?
Host A:nstcloudcc1 configuration:
nstcc1@nstcloudcc1:tmp$ ib2netdev
mlx5_0 port 1 ==> ens261f0 (Up) 173.168.100.103
mlx5_1 port 1 ==> ens261f1 (Down)
nstcc1@nstcloudcc1:tmp$
Host B:rdmarhel0 configuration:
[rdma@rdmarhel0 tmp]$ ib2netdev
mlx5_0 port 1 ==> ens801f0 (Up) 173.168.100.101
mlx5_1 port 1 ==> ens801f1 (Up) 192.168.100.101
[rdma@rdmarhel0 tmp]$
Run below command on host A as server:
nstcc1@nstcloudcc1:tmp$ qperf
Run below command on host B as client:
[rdma@rdmarhel0 tmp]$ qperf 173.168.100.103 rc_bw
rc_bw:
failed to modify QP to RTR: Invalid argument
The log shows as above on cient that it failed to modify QP to RTR
--Thanks

Does anyone use qperf to compare TCP & RDMA-RC-Send/Recv bandwidth and latency?
