IB card opens EIPOIB for virtualized bridging use

?

Step 1: Turn on EIPOIB

Edit Default "No" to "yes"

/etc/infiniband/openib.conf

e_ipoib_load=Yes

Step 2: Restart the HCA card driver.

/ETC/INIT.D/OPENIBD restart

The Ethernet card is generated after the reboot, and the NIC rate can be confirmed with Ethtool exxx.

Restart the OS if the service fails to restart.
