If the profile is correct and NetworkDirect is enabled, you should see active
NetworkDirect listeners on IP addresses (port 445) assigned to the NICs using
“netstat -xan”.
Using SMB Direct with NetworkDirect
Because RoCE is supported in Windows using SMB Direct with NetworkDirect, it is
important that SMB Direct and NetworkDirect be configured correctly.
From the Advanced tab of the Network Interface Properties page:
1. Enable the “NetworkDirect” parameter.
2. Set the NetworkDirect MTU. Emulex recommends a NetworkDirect MTU of 4096
bytes for OCe14400-series adapters.
Note: The NetworkDirect MTU affects only RoCE traffic, but the NIC traffic still uses
the “Packet Size” MTU. An SMB Server will accept an incoming connection
request from an SMB Client when the NetworkDirect MTU on the server is at
least as large as the NetworkDirect MTU on the initiating client.
3. Use the “netstat -xan” command to enumerate the active NetworkDirect
connections and listeners (Figure 3-11). A NetworkDirect enabled driver creates
listeners on any configured IPv4 or IPv6 addresses, and the link-local IPv6 address.
SMB Direct listeners listen on port 445.
