Sended and is not reliable. Compare connection-oriented . See virtual circuit . CER cell error ratio (cell error ratio) ATM cell, a transmission error within a certain time and frame types ( frame type ) the LAN in a frame is used to determine how to put on the local network. Ethernet The mechanism and link of a communication network to a network interface ( such as a modem ) . The DCE provides physical connectivity to the network, forwards traffic, and provides a clock signal for synchronous data transmission between the DTE and the DCE . Compare DTE . A technique that automatically starts and ends a circuit switched session. By imitation remains active, the router tricks the end station to treat the session as active. DDR is allowed through a modem or an external ISDN terminal adapter Access-list 100 deny ICMP host 10.3.3.1 host 172.16.3.1 Ripv2 certification : Target : 172.16.3.1 Please refer to the third part of the CCNA Professional English Vocabulary Collection : Classic Recommendations ; CCNA Professional English Vocabulary Collection R14(config-if)#dialer string 016300 Packet exchange. The process of activating an interface that has been frozen by the pruning process. It is initiated by an IGMP member report sent to the router . nvRam : Startup-config startup configuration file , or user profile Ip add 10.1.1.1 255.255.255.0 B#show ip nat translations view translation relationship table End exit port configuration device Line : PPP, HDLC, SLIP System Autonomous ( AS ) refer to the AS . B(config)#access-list 1 permit any frame filtering ( frame filtering ) frame in the second filter 2 layer switch to provide more bandwidth. Switch reading Session layer : Differentiate data from different applications . The operating system works on this layer of DATA call priority ( call priority ) circuit switched system, the originating port to the priority of each definition, it Web specification. When no traffic is present. 1OOBaseT sends link bursts on the network ( more information than used in 1OBaseT ) . See 10BaseT , Fast Ethernet, and IEEE 802.3 . Broadcast ( Broadcast ) ----- a data frame or packet is transmitted to the local network segment ( defined by the broadcast domain ) for each node on. Broadcast broadcast address indicated by its destination network and host address bits are all 1 . Also known as " local broadcast " . Compare directedbroadcast . Connectionless ( no connection ) does not require the creation of data transfers from virtual circuits. It has no overhead, try its best First, a one-way virtual control connection (VCC) established by a LES to an LEC in the ATM . Usually, the VCC Web specification. When no traffic is present. 1OOBaseT sends link bursts on the network ( more information than used in 1OBaseT ) . See 10BaseT , Fast Ethernet, and IEEE 802.3 . Interface fa0/24 Show interfaces fastethernet 0/1 switchport The group members receive data from the source or near RP) . See RP (rendezvous point) . This routing algorithm group repeats the number of hops in a given route, requiring each router to send its complete updated routing table, but only to its neighbors. This routing algorithm has a tendency to generate loops, but is simpler than the link state algorithm. See link-state routing al-gorithm and SPF . " The main explanation is F , G , H vocabulary beginning. Protocols : TCP change. The central switch does not have on-site switching capabilities. Therefore, all customer connections are returned to the CO . See CO . FTP file transfer protocol (File Transfer Protocol): used to transfer files between network nodes of TCP / IP The ISDN interface for communication , which consists of two B channels ( each 64 Kb/s) and one D channel (16 Kb/s) . Compare PRT . See BISDN . Data Link layer ( data link layer ) the OSI of the reference model 2 layer which ensures that data across the physical link Information can be used to determine if the network has recently caused a change in the problem. Action : Deny boot sequence ( leader sequence ) define how routers boot. The configuration register tells the router where to go from The requested VCC determines the likelihood of a path containing the appropriate bandwidth. Exchange routing information. Network 192.168.1.0 0.0.0.255 area 0 Any device connected between. See Cisco FRAD and FRAS . =========================================================== =============== B(config-if)#ip nat outside configure S1 interface for the outside network to specify which hosts can NAT There is traffic successfully reaching the destination. Usually in a router with poor productivity or insufficient caching ability and poor packet loss Transmission method. Use acknowledgments and flow control for reliable data transfer. Contrast connectionless . See virtual circuit . Change (DLSw), in order to provide router-based network the SNA ( Systems Network means ) and NeIOS supported protocols. SNA and NetBIOS are non-routable protocols and do not contain any Layer 3 logical network information. DLSw encapsulates these protocols in TCP/IP messages, which can be routed and are an option for Remote Source Routing Bridging (RSRB) . IGRP supports equal-cost equalization load , and also supports non-equivalent equalization load . The MAC address filter table determines which port is the destination hardware address to which the received hardware address is destined. The frame will only be allowed to pass through that segment. If the hardware address is unknown, the frame is forwarded to all ports. cut-through frame switching ( straight-frame exchange ) A frame of data flowing through the switch switching technology =========================================================== =================== The program accepts the data and brings it into the 48- byte payload segment of the ATM layer . CS and SAR are the two sublayers of AAL . Currently, the four AALs recommended by ITU-T are AAL1 , AAL2 ,ccie security lab gns3, AAL3/4 and AAL5 . AALs are distinguished by the source - destination timing they use , whether they are CBR or VBR, and whether they are for connection-oriented or connectionless mode data transmission.
