WebAug 2, 2024 · The transferred RDMA packets are marked with layer 3 DSCP, layer 2 Priority Code Points (PCP) or with both. To extract priority information from the packet routers use either DSCP or PCP. In case PCP is used, the packet must be VLAN-tagged and the router must copy the PCP bits of the tag and forward them to the next network.

WebWhen sending multicast traffic, if the network frequently reconfigures, chances are that some device in the network doesn't support large frames. Choose hardware carefully if intending to use large frame support. The default is 1500. threads This directive controls how many threads are used to encrypt and send multicast messages.
