Yevgeny, iSER (as you can learn from doing a grep) is using the RDMA-CM TCP port space as does RDS. The RDMA-CM signature is something which I am sure exists, you can look on the RDMA-CM IB spec Annex to see if such thing indeed exist or I am wrong. The TCP port is the 16 bit port portion of the ip:port address provided by a ULP that uses the RDMA-CM to rdma_resolve_addr(), again the annex explained how the port is embedded into the SID, I don't remember the location within the 64 bit string.

For SDP it's 0x10000 - 0x1FFFF. For RDS it's 0x1060000 - 0x106FFFF For iSER it's ...? > 2) the rdma cm signature Do you mean something iSER-specific, or just the way the cm builds the service ID out of port space and tcp port? Can you give an example? > 3) the destination tcp port provided to rdma_resolve_addr I guess that tcp port is in the lower 4 nibs of the service ID, similar to SDP.
