Overview SuperStack II bridge/routers maintain connectivity among small, midsize, and large branch ofﬁces and the corporate LAN.
Page 24: Using Wan And Serial Ports
SING THE RIDGE Using WAN and SuperStack II NETBuilder SI bridge/routers come with two or four serial Serial Ports ports and one of the following WAN ports: a built-in ISDN S/T terminal adapter (TA) (models 43x and 53x), a built-in ISDN U TA (models 44x and 54x), a built-in 56/64 Kbps CSU/DSU (models 45x and 55x) or a built-in T1/FT1 Telco port (models 46x and 56x).
Page 25: Serial Ports
You can buy Flex-WAN cables separately from 3Com. See Appendix D for more information about Flex-WAN cables. If you are using two SuperStack II NETBuilder SI bridge/routers connected directly to each other by the serial ports (back-to-back), the bridge/routers do not meet radiated emissions speciﬁcations.

This chapter describes how to start up the system, log on, use the user interface, and perform basic administrative tasks that you must complete before conﬁguring the ports and paths and bridging or routing protocols that you plan to run on your bridge/router. Table 9 summarizes the administrative tasks described in this chapter and indicates whether performing each task is required, recommended, or optional.

When the startup process has Startup successfully completed, the LEDs on the front panel should be on or off as described in Table 10. If the LEDs on your bridge/router appear different from those shown in Table 10, the bridge/router may have a problem.

Page 63: Basic
This chapter contains conceptual information about ports and paths and contains basic conﬁguation procedures for each of the interfaces on your SuperStack II NETBuilder SI bridge/router. Paths, Ports, and Ports and paths are the fundamental interface units on the bridge/router, Virtual Ports and understanding the concept of ports and paths is important.
Page 64: Dynamic Paths
6: B HAPTER ASIC ONFIGURATION OF A port is the logical interface used by the software to represent a connection to a network. By default, each path is assigned to one port. For example, all network trafﬁc received on physical path 1 is treated by the software as arriving on logical port 1, and all trafﬁc that the software transmits through logical port 1 passes through physical path 1.
Page 65: Multiple Static Paths Per Port
Multiple Static Paths If you assign multiple paths to a port, the port must be running PPP. per Port To use both B channels together on a built-in ISDN connector, to reserve a path for disaster recovery, or to use another path for dial-on-demand, failover, or bandwidth-on-demand, you can assign both paths to one port and use Multilink PPP using: ADD !<port>...
Page 66: Virtual Ports Over Frame Relay And X.25
6: B HAPTER ASIC ONFIGURATION OF Virtual Ports over Frame Relay and X.25 Frame Relay and X.25 are peer-to-peer protocols that connect two nodes on the network. Boundary Routing and bridging, Internet Protocol-Open Shortest Path First (IP-OSPF), DECnet IV, VINES, and Xerox Network Systems (XNS) require virtual ports because they do not provide a method for dealing with Frame Relay or X.25 topologies where bridge/routers are not directly connected to all others (full mesh).

Although the WAN connector on the model 5xx bridge/router is in a different physical location than the WAN connector on the model 4xx bridge/router, its path numbering is the same.

Scenario 1: Using Each B Channel Separately If you need to connect to two separate locations at 64 Kbps, use each B channel separately. Each B channel can connect to only one location, though both locations can be separate ports on the same bridge/router. Each B channel connects separately to one destination.
Page 82: Scenario 2: Using Both B Channels Together
7: A HAPTER DVANCED ONFIGURATION OF Scenario 2: Using Both B Channels Together If you need to connect to one location at 128 Kbps, use both B channels together. The destination must be running Multilink PPP, either on the NETBuilder bridge/router with a built-in ISDN port or on the TA.
Page 83 The following prerequisites apply to your network: To use both B channels together, the destination must be running Multilink PPP, either on the NETBuilder bridge/router with a built-in ISDN port or on the TA. If you use built-in ISDN ports and ISDN TAs in the same dial pool, and you are using Multilink PPP on the SuperStack II bridge/router, you can use the TA at only 56 or 64 Kbps.

Use virtual ports to pass trafﬁc from one site to another over the same parent port. Instead of using virtual ports (if you run out of virtual ports, for example), you can use the next-hop split horizon feature in the routing protocol.
