I have 2 servers(Ubuntu 22.04) connected over a network with Mellanox Connect 5X card installed and an ipv6 address assigned to each of them. Basic connectivity over the network works as I am able to ping the servers from each other.
Trying to send RDMA traffic over this network (ROCE v2), i try the following commands -
Server - ib_send_bw --ib-dev=mlx5_1 --ipv6
Client - ib_send_bw <server_addr> --ib-dev=mlx5_1 --ipv6
The client always throws the error message -
“”“”
Address family for hostname not supported for 1001:1:1:1::2:18515
Problem in resolving basic address and port
Unable to open file descriptor for socket connection Unable to init the socket connection
“”“”
Am I missing something ?
(NSlookup also returns the correct ipv6 address for this host, hence the above error message is confusing)
ib_send_bw on another setup with ipv4 address seems to be working fine. So unable to figure out why the command with ipv6 address is not working.
Some more details of the card configuration -
Note - Both server and Client have similar configuration on the cards.
