How can we use X710 hardware mac filter?

[EHuan]

Hi Sir,

We want to use the feature of x710 to filter(L2) some types packets to specific virtual machines(VMs) and a VM deals with a type packets.

Could you please supply some suggestions?

Thanks.

Hi Crisselle ,

1.

2.

When x710 receives packets, we hope separate some type packets to different Virtual Machines(VMs).

A VM only deals with one type packet.

Thank you!

Filters to Direct Traffic to a Specific VF

------------------------------------------

It is possible to create filters that direct traffic to a specific Virtual

Function. For older versions of ethtool, this depends on the "action"

parameter. Specify the action as a 64-bit value, where the lower 32 bits

represent the queue number, while the next 8 bits represent the VF ID. Note

that 0 is the PF, so the VF identifier is offset by 1. For example:

# ethtool -N <ethX> flow-type tcp4 src-ip 192.168.10.1 dst-ip \

192.168.10.2 src-port 2000 dst-port 2001 action 0x800000002 [loc 1]

The action field specifies to direct traffic to Virtual Function 7 (8 minus 1)

into queue 2 of that VF.

Newer versions of ethtool (version 4.11 and later) use "vf" and "queue"

parameters instead of the "action" parameter. Note that using the new ethtool

"vf" parameter does not require the value to be offset by 1. This command is

equivalent to the above example:

# ethtool -N <ethX> flow-type tcp4 src-ip 192.168.10.1 dst-ip \

192.168.10.2 src-port 2000 dst-port 2001 vf 7 queue 2 [loc 1]

Note that these filters will not break internal routing rules, and will not

route traffic that otherwise would not have been sent to the specified VF.

If you have additional questions and clarifications, please do not hesitate to ask.
