turn on multicast with linux native interface #1094
Comments
It seems promiscuous mode can let all package go through |
@tianhengzhou the multicast enable is per driver, the net_af_packet is not the common case of dpdk driver |

I run my Trex server in stateless mode and with interfaces defined with Linux interface names.
This is what's shown in the TRex book under low-end machines sections.
3.5 Linux interfaces
Another interesting low-end use case is using native Linux interfaces.
With that, I'm trying to turn on multicast mode for the port in the trex-console via
portattr -p 0 --mult on
The port multicast mode won't turn on, keep at off.
I have a similar setup with PCID in the interface like the following
interfaces: ['01:00.0', '05:00.0']
I can switch on multicast for a port without a problem.
I wonder if this Linux interface's low-end mode won't work with multicast
There isn't anything mentioned in the doc that multicast doesn't work for this low-end use case.
