Hi Everyone,
We are facing an issue with symmetric hashing. 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.
