Members

dl_primitive

Must be the manifest constant DL_SUBS_BIND_REQ_T.

dl_subs_sap_offset

Specifies offset to byte sequence below. The offset points to the byte sequence composed of the SNAP header followed by the Ethernet type. The SNAP header given must match the SNAP header received off the wire.

SNAP header

3 bytes

Ethernet type

2 bytes

dl_subs_sap_length

Specifies length of subsequent SAP; must be 5.

dl_subs_bind_class

Specifies subsequent SAP bind class; must be DL_HIERARCHICAL_BIND.
