SNA Gateways

Gateway Some hints specific to SNA gateways are given below.
• AXIS 5470e appears to a gateway as a Down Stream Physical
Unit (DSPU), with eight LUs, 1 to 8 (LU 1 may not be available).
• Only gateways that communicate with DSPUs using SNA over
LLC type 2 are supported.
• There are basically two types of gateways that the AXIS 5470e
can be attached to: pass-through gateways and concentrator
gateways, as described below.
Devices attached downstream to this type of gateway are completely
visible to the host. In other words, each DSPU will have a PU
definition on the host. Examples of pass-through gateways are IBM
3745 Communications Controller, IBM 3174 Establishment
Controller, IBM 3172 LAN Interconnect Controller, etc.
You need to set up at least one PU and LU definition for each AXIS
5470e on the host, as described in the VTAM section.
When attaching an AXIS 5470e to a remote pass-through gateway,
you need to set the mapping of SDLC or sub-channel address to MAC
address in the gateway.
