INTERNETWORKING AND MANAGEMENT OVERVIEW 8 This chapter provides an overview of internetworking and network management concepts used by the Campus-REX2. You can configure the Campus-REX2 as a bridge to forward Ethernet data based on MAC addresses, or as a router to route Ethernet data based on IP addresses. You can also configure parameters for management and encapsulation protocols.
Chapter 8 - Internetworking and Management Overview COMPOSITION OF A CAMPUS-RS SYSTEM Campus-RS products accommodate a wide range of network interfaces and access speeds in a single platform solution. A Campus-RS system comprises these primary elements: • Campus-RS desktop unit—The desktop unit provides a DSL (WAN) interface that connects to a line unit (DSL interface) in a Campus-Star chassis or back-to-back with another desktop unit DSL interface.
Chapter 8 - Internetworking and Management Overview APPLICATION The Campus-REX2 must be installed into a Campus-RS or Campus-HRS desktop unit or with a Campus-RS or Campus-HRS line unit. It cannot be installed in an older Campus desktop unit or with an older Campus line unit. The Campus system, implementing Campus-REX2 interface cards, provides a connection between geographically distributed Ethernet Local Area Networks (LANs) in a campus environment. The Campus-REX2 performs transparent 802.
Chapter 8 - Internetworking and Management Overview Point-to-Point LAN Extension As organizations move or change, LANs also evolve and may become fragmented or physically separated. The Campus-REX2 provides a lower-cost alternative to other LAN-extension solutions. The Campus-REX2 provides a built-in 10/100Base-T LAN interface that eliminates the need for other internetworking devices while providing 30 times the performance of other sub-rate wireless connectivity options, as shown in the following figure.
Chapter 8 - Internetworking and Management Overview LAN Connections Over a WAN When LANs are distributed over a large physical area (such as within a metropolitan area) or cabling is not available between sites, you can lease appropriate unloaded copper pairs from a local carrier for LAN connectivity. For transport over public networks, you can connect the public T1 network (DSX-1 signal) to the LAN through desktop units with CSU/DSX-1 interface cards and the Campus-REX2 in a desktop unit.
Chapter 8 - Internetworking and Management Overview MAC-LEVEL BRIDGING AND SPANNING TREE PROTOCOL The following sections describe the MAC-level bridge and the Spanning Tree algorithm function. About MAC-Level Bridging A bridge moves information across an internetwork from a source to a destination at the link layer (of an OSI reference model). The information is sent to a physical address known as a Media Access Control (MAC) address. The Campus-REX2 provides transparent Ethernet MAC-level bridging.
Chapter 8 - Internetworking and Management Overview Example Physical Network* LAN Bridge 1 Bridge 2 Bridge 3 ENET 1 Bridge 4 LAN E N E T 2 Bridge 5 ENET 3 Loop-free Topology Using Spanning Tree Protocol LAN Bridge 1 Bridge 2 Bridge 3 ENET 1 Bridge 4 E N E T 2 LAN Bridge 5 ENET 3 *This physical configuration is valid only when used with Spanning Tree to eliminate loops.
Chapter 8 - Internetworking and Management Overview To enable or disable Spanning Tree, see “Configuring Spanning Tree Protocol” on page 33. The following elements are required for managing the Spanning Tree active topology: • assigning a priority to each bridge relative to all bridges within the bridged LAN • assigning a priority to each bridge port relative to all ports on a bridge • assigning a path cost to each port IP ROUTING The Campus-REX2 offers both dynamic and static routing.
Chapter 8 - Internetworking and Management Overview The figure on page 128 shows a more complex example of multiple gateways that use static IP routing to route packets sourced from specific users to different destination gateways. In this example, packets from each subscriber are routed through a common hub to a router dedicated to that subscriber.
Chapter 8 - Internetworking and Management Overview Configure a Static Route entry in any of the external routers that may have been specified as a Default Router IP address or as a Gateway address in the Campus-REX2. You may also configure the Campus-REX2 to send periodic route updates using Routing Information Protocol (RIP) so that other external routers can automatically update their routing tables.

Chapter 8 - Internetworking and Management Overview MANAGEMENT PROTOCOLS SNMP is used for remote configuration of system and bridge parameters, monitoring statistics, and performing advanced management. FTP is used for the Campus-REX2 to download system software code. SNMP This messaging protocol specifies how to send information between a Network Management Station (NMS) or Element Management System (EMS) and managed devices on a network.
Chapter 8 - Internetworking and Management Overview The Campus-REX2 provides an SNMP agent that supports several MIBs for the management of the system. The SNMP agent can process datagrams received from both the Ethernet interface (LAN) and the HDSL interface (Line). See “MIB and Trap Support” on page 133 for a list of MIBS that are supported. Telnet Telnet is a standard TCP/IP protocol used for remote terminal service.
Chapter 8 - Internetworking and Management Overview • RFC 1493, Definition of Managed Objects for Bridges. Covers: Base, Spanning Tree, and transparent bridging groups. The Spanning Tree MIB can only be accessed if the Spanning Tree protocol is enabled. • PG-REX2-MIB, an enterprise specific MIB designed for the agent in the Campus-REX2 for managing the HDSL portion of the unit. The Campus-REX2 sends traps to devices on the network, which you configured as trap receivers, when events or alarms occur.
Chapter 8 - Internetworking and Management Overview ENCAPSULATION PROTOCOLS You can select from two packet encapsulation formats for Ethernet data for the Campus-REX2: • compressed High-level Data Link Control (cHDLC) • Point-to-Point Protocol (PPP) The default setting is cHDLC and should be used in applications with another Campus-REX2. Use PPP only if the remote unit is a synchronous interface card, such as V.35.
