NOTE Introduction to DLPI Promiscuous Mode Clarifications Promiscuous Mode Clarifications The following definitions are being defined for the various levels of promiscuous mode. DL_PROMISC_PHYS-If enabled before the STREAM has been bound (with the DL_BIND_REQ primitive), the DLPI user receives all traffic on the wire regardless of SAP or address. If enabled after the STREAM has been bound, the DLPI user receives all traffic on the wire that matches the protocol(s) the user has bound to on the promiscuous STREAM. This includes protocols bound with the DL_SUBS_BIND_REQ. DL_PROMISC_SAP-If enabled before the STREAM has been bound (with the DL_BIND_REQ primitive), the DLPI user receives all traffic destined for this interface (physical addresses, broadcast addresses or bound multicast addresses) that matches any SAP enabled on that interface. If enabled after the STREAM has been bound, the DLPI user receives only those packets originally destined for the interface that match one of the protocol(s) bound on the promiscuous STREAM. DL_PROMISC_MULTI-Before the STREAM has been bound (with the DL_BIND_REQ primitive), the DLPI user receives all multicast packets on the wire regardless of the SAP. After the STREAM has been bound, the DLPI user receives all multicast packets that match one of the protocol(s) bound on the promiscuous STREAM. Fine-grained Privileges Starting HP-UX 11i v3, HP DLPI allows enabling and disabling of promiscuous mode only for users with the PRIV_NETPROMISCUOUS privilege. For more information on the fine-grained privileges, see "Fine-grained Privileges" on page 17. Each LAN interface currently allows only one unbound stream to enable the promiscuous mode service.
