DLSw Configuration Overview
114063 Rev. A 3-13
You enter slot information in the DLSw Slot IP Table during the initial
configuration procedure. Refer to Chapter 5 for more information about accessing
and editing the DLSw Slot IP Table.
DLSw Peer IP Table
Data link switches that connect to the same TCP/IP network are called DLSw
peers on that network. On Bay Networks routers, each slot that you configure with
DLSw services functions as an independent DLSw peer. Other vendors may offer
RFC 1434/1795-compliant products that support either single or multiple DLSw
peers internally. For example, each IBM6611 processor in your network serves as
a single DLSw peer that you must define on the router.
TCP/IP sessions between DLSw peers can exchange information between devices
attached to each peer. In each router, you can define a list of peers identifying
remote routers with which a DLSw session can be initiated. These are called
configured peers, and are defined in the DLSw Peer IP Table.
You can establish DLSw peer configurations that include only Bay Networks
routers or a mix of Bay Networks routers, and other RFC 1434- and
RFC 1795-compliant devices.
Configured Peers
A configured peer is a remote data link switch, represented by an IP address, that
is predefined in the local router. You define a configured peer by specifying its
unique IP address in the Site Manager DLSw Peer IP Table.
IP addresses in the local router’s Peer IP Table must also appear in the Slot Table
of a remote router.
A configured peer can receive broadcast frames directly from DLSw peers in a
local router.
The local router issues broadcast frames triggered by client demand for
connection services. Responses to these broadcasts enable the local router to
• Identify DLSw peers that can reach the requested remote NetBIOS or SNA
system
• Manage (open, restart, and close) TCP connections to the DLSw peer that can
reach the requested SNA or NetBIOS system
