Appendix C SNMP Understanding SNMP As Local Area Network (LAN) environments became standardized over the past ten years, multi-vendor equipment grew with competition. It became necessary to manage the various vendor equipment from a single control console. Thus, the Simple Network Management Protocol (SNMP) emerged as the de facto standard for managing commercial Transmission Control Protocol/Internet Protocol (TCP/IP) networks.
Appendix C: SNMP Using SNMP Version 1, the network manager can issue three types of commands: • GetRequest: This command retrieves a single item or the first in a series from a network device. • GetNextRequest: This command retrieves the next item in a series from a network device. • SetRequest: This command writes information to a network device. The network device issues two types of messages: • GetResponse: This message is the response to a network manager GetRequest or GetNextRequest command.
Appendix C: SNMP Communities The Express L768/L1.5 permits up to eight communities to be defined. The privilege level of each community can be set. The default community is public with read-only privileges. When the IP address is all zeros, any manager of the community can access the Express L768/L1.5. Traps Up to four hosts can be set to receive traps. Each host entry requires an IP address of the manager. Trap types supported are: cold start, link up, link down, and authentication failure.

Glossary 10Base2 IEEE 802.3 specification, similar to Ethernet, using thin coaxial cable that runs at 10 Mbps, with a maximum distance of 185 meters per segment. Also known as Thin Ethernet or Thinwire Ethernet. 10BaseT IEEE 802.3 specification, using unshielded twisted-pair cabling and running at 10 Mbps. AEP ARP AppleTalk Echo Protocol. Allows a node on an AppleTalk network to send a packet to another node and in return, receive an echoed copy of the packet. Address Resolution Protocol.
Glossary CCITT Consultative Committee on International Telephony and Telegraphy. A body of the International Telegraph Union (ITU) which prepares recommendations, commonly referred to as international standards, to resolve technical telegraph and telephone problems. central office (CO) In telephony, the phone company switching facility or center, usually a Class 5 end office, at which subscribers local loops terminate.
Glosssary four-wire circuits Telephone lines using two wires for transmitting and two wires for receiving, offering much higher quality than a 2-wire circuit. All long distance circuits are 4-wire. Almost all local phone lines and analog phones are 2-wire. Frame Relay A streamlined subset of the X.25 packet switching protocol which has been used by many corporations for wide area communications for a number of years. group 4 HDSL A high-speed (56 kbps) facsimile protocol specific to ISDN.
Glossary IEEE 802.3 A physical layer standard specifying a linear bus network LAN with a CSMA/ CD access method on a bus topology. Ethernet follows the 802.3 standard, transmitting at 10 megabits per second. This is the most common local area network specification. Physical variations of IEEE 802.3 include 10Base2 and 10BaseT. in-band signalling Signalling made up of tones which pass within the voice frequency band and are carried along the same circuit as the talk path being established by the signals.
Glosssary jitter LATA The slight movement of a transmission signal in time or phase that can introduce errors and loss of synchronization for high-speed synchronous communications. See phase jitter. Local Access and Transport Area. One of 161 local telephone serving areas in the United States, generally encompassing the largest standard statistical metropolitan areas. Subdivisions established as a result of the AT&T divestiture that now distinguish local from long distance service.
Glossary netmask A 32-bit bit mask which shows how an Internet address is to be divided into network, subnet, and host parts. The netmask has ones in the bit positions in the 32-bit address which are to be used for the network and subnet parts, and zeros for the host part. The mask should contain at least the standard network portion (as determined by the address's class), and the subnet field should be contiguous with the network portion.
Glosssary router An interface which finds the best route between two networks. Routers forward packets from one network to another, based on network layer information. routing metric The method by which a routing algorithm determines one route is better than another. This information is stored in routing tables. Such tables include reliability, delay bandwidth, load, MTUs, communication costs, and hop count.
Glossary spoofing Spoofing reduces the required bandwidth by having devices, such as bridges or routers, answer for the remote devices. This causes the remote LAN to appear as if it is still connected to the LAN device even though it is not. The spoofing saves the WAN bandwidth, because no packet is ever sent out on the WAN.
Glosssary 2B+D 23B+D The Basic Rate Interface (BRI) in ISDN. A single ISDN circuit divided into two 64 kbps digital channels for voice or data and one 16 kbps channel for low speed data (up to 9,600 baud) and signalling. 2B+D is carried on one or two pairs of wires depending on the interface, the same wire pairs that today bring a single voice circuit into your home or office. See ISDN. In ISDN, also known as the Primary Rate Interface.
