Field Descriptions
Name:
This is the name that has been assigned to the gateway circuit in the
configuration panels.
LAN Adapter:
This is the name of the LAN adapter that the Gateway Circuit is being
assigned to. The LAN adapter selected can be any of the LAN adapters that are
configured to have an XCA circuit connection. The assignment is virtual since gateway
traffic is never actually sent to the LAN adapter listed, but is directed to the Gateway
Circuit logic instead.
PUID/CP Name:
When a Gateway Circuit is active, the PUID that was sent to VTAM
(from a PU 2.0 node) or the CP Name (from a PU 2.1 node) that was sent to VTAM will
be displayed.
VTAM SAP:
This is the configured VTAM SAP number that is associated with the
XCA node definition in VTAM. Since multiple XCA circuit definitions can be associated
with a single network adapter, the VTAM SAP tells VTAM and the associated network
card which XCA circuit is being used.
MAC Address:
This field identifies the MAC address of the downstream PU2 client
using the gateway circuit. In the case of SDLC gateway circuits, this represents a virtual
MAC address that has been configured to represent the PU2 node. VTAM believes it is
communicating with a network attached node communicating through one of the network
adapters, so a destination MAC address is used in the communications packets. All traffic
using the configured destination MAC address will be diverted and processed for the
gateway circuit, and all traffic passing upstream through the gateway circuit will be sent
to VTAM as if it were being sent from the virtual MAC address.
SAP:
Like the Virtual MAC Address, a virtual SAP is also required to complete the
addressing required by VTAM for the virtual nodes.
Destination ID:
The Destination ID identifies the configured drop that the Gateway
Circuit is using on the downstream side of circuit.
Button Definitions
Return:
Pressing this button returns you to the previous panel, the main ESCON status
panel.
