Below is the definition of symmetric hashing. The traffic from server A to server B and server B to server A should fall under the same flow. This is what we call symmetricity. I have configured the customized keys for symmetric hashing as suggested in the DPDK forum. After changing the key to the below symmetric hashing started working. *static uint8_t hash_key[RSS_HASH_KEY_LENGTH] = {* * 0x6D, 0x5A, 0x6D, 0x5A, 0x6D, 0x5A, 0x6D, 0x5A,* * 0x6D, 0x5A, 0x6D, 0x5A, 0x6D, 0x5A, 0x6D, 0x5A,* * 0x6D, 0x5A, 0x6D, 0x5A, 0x6D, 0x5A, 0x6D, 0x5A,* * 0x6D, 0x5A, 0x6D, 0x5A, 0x6D, 0x5A, 0x6D, 0x5A,* * 0x6D, 0x5A, 0x6D, 0x5A, 0x6D, 0x5A, 0x6D, 0x5A,* *};* *But it is working in ESXI server version 6.7.0, but does not work in ESXi server version 7.0.0.* Anyone aware of this issue. *We are using the vmxnet3 driver and DPDK version 19.11.* Regards, Ramkumar N.
