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. Use telnet protocol to access the Campus unit for configuration and management over the Internet. From the Windows Start menu, select Run. Enter the telnet command and the IP address for the Campus-REX2 (default IP address is 192.168.1.1). The timeout for disconnecting a telnet session is five minutes (time frame with no keyboard activity to the Campus unit).

FTP

File Transfer Protocol is a TCP/IP standard that is used for moving files between devices. Use FTP when you are downloading upgrade software to the Campus unit from a server or other network device.

MIB AND TRAP SUPPORT

Each managed device has configuration, status, and statistical information that defines its functionality and operational capabilities. All of these elements make up the MIB for the device being managed. The MIB defines the kind of information an NMS can retrieve from a managed device and the settings an NMS can control in a managed device.

The Campus-REX2 supports the following MIBs:

•RFC 1213/STD 17, Management Information Base for Network Management of TCP/IP-Based Internets: MIB-II. Covers: system, interfaces, IP, ICMP, UDP, and SNMP groups. The Ethernet interface has the ifIndex value of 1.

•RFC 1215, A Convention for Defining Traps for Use with the SNMP. Covers: ColdStart, linkUp, linkDown, and authenticationFailure traps. Link status traps are sent for events related to Ethernet.
