Notes:

1. add dev defines a single port, not an adapter.

2. The configuration program assigns an interface number to all ports of an adapter automatically and you delete the ones you do not want to use. From the command line, you type the add dev command for each port you want to use, and the interface number (also known as "net number") is the output of the command.

3. You need a write-capable SNMP community only if you want to download configuration files from the configuration program directly into the router. SNMP is not required to TFTP a configuration file to the router.

4. Only Interface 1 needs to be configured for IP for DLSw to function correctly in this example. Interface 0 is configured here for IP, solely for box management purposes.

5. You can also use RIP in place of OSPF.

6. We disable the forwarding of remote explorers as a general filter, to prevent backbone LAN traffic from generating DLSw search messages on the WAN links to remote sites. This means that all circuits must be initiated by the remote routers. If your network requires the host to be able to initiate connections out to the remote sites, change this parameter to "forward to all DLSw peers".

   If the remote routers are IBM routers, you can configure them individually to control which search messages they want to receive, using MAC address and NetBIOS name lists. You can also configure whether each will bring up its TCP connection to Network Utility all the time or drop it when unused, using the connectivity setup type parameter.

7. Having dynamic neighbors enabled is the default value, so you do not have to change this panel or issue this command. We show it here to point out that this is the parameter that allows remote DLSw partners (neighbors) to establish TCP connections to this Network Utility without you having to define their IP addresses here. Each remote router needs to be configured with this Network Utility's internal IP address (172.128.252.1) as its partner address.

8. SAPs do not need to be opened on Interface 1 since that interface is only carrying IP traffic and not LLC traffic.

9. "enable br" automatically creates TB bridge ports for both token-ring interfaces. Bridge port numbers are 1 and 2, and are independent of adapter port numbers.

10. The disable and enable commands change bridge port 1 from TB to SRB. The "delete port" command turns off bridging on interface 1 (bridge port 2). Bridging would be required on this interface if we needed to support local end station traffic bridging from the Campus Backbone to the host.

Notes:

1. add dev defines a single port, not an adapter.

2. The configuration program assigns an interface number to all ports of an adapter automatically and you delete the ones you do not want to use. From the command line, you type the add dev command for each port you want to use, and the interface number (also known as "net number") is the output of the command.

3. The MAC address representing this LSA loopback interface is the target MAC address that all end stations in the DLSw network use to reach the host through this Network Utility.

4. You need a write-capable SNMP community only if you want to download configuration files from the configuration program directly into the router. SNMP is not required to TFTP a configuration file to the router.

5. You could choose to use RIP in place of OSPF.

6. We enable local forwarding to allow end stations on the local campus to reach the host. We disable the forwarding of remote explorers as a general filter, to prevent backbone LAN traffic from generating DLSw search messages on the WAN links to remote sites. This means that all remote circuits must be initiated by the remote routers. If your network requires the host to be able to initiate connections out to the remote sites, change this parameter to "forward to all DLSw peers".

Each remote router needs to be configured with this Network Utility's internal IP address (172.128.252.1) as its partner address.

8. Adding the internal IP address as a neighbor is required to enable DLSw to carry traffic from the ESCON/LSA interface to the backbone LAN.

9. SAPs are opened on Interface 0 to enable the LLC flow to the local LAN switches, and are not required for remote DLSw to work.

10. "enable br" automatically creates a TB bridge port for the token-ring interface. The bridge port number is 1, and is independent of adapter port numbers and box interface numbers.

11. The disable and enable commands change bridge port 1 from TB to SRB. Bridging is required on this interface to support local end station traffic looping through DLSw from the Campus Backbone to the host.
