How to configure multiple UEs to a single GnB using PacketRusher?

[madhavEdgeq]

I'm trying to simulate multiple UE's connected to a single GnB with traffic running. Is this possible to do with packet rusher? When I try running without the dedicated GnB: sudo ./packetrusher multi-ue -n 6 I see six UE's created with a single GnB on the core but no interface is created so am not able to run traffic using iperf3. Is there a way to run traffic in this manner? Thanks!

Hi @madhavEdgeq,

Happy to see you using PacketRusher! To run multiples UEs at the same time, you need to add the --tunnel and --dedicatedGnb option: sudo ./packetrusher multi-ue -n 6 --tunnel --dedicatedGnb, which will create one gNodeB per UE and the associated tunnel.
For now, sadly, you cannot create multi-ue on a single gNodeB if you want to have a tunnel.
More information on --dedicatedGnb here: #65 (comment) and on why this limitation exists for now here: #111 (comment)

Cheers,
Valentin
