  • Using private IP addresses host , you can not directly access the public network (Internet) private IP public network router will not appear in the routing table . Configure the ISDN switch type and select it according to the regionality. lOBaseT , Fast Ethernet, and lEEE . Rate enhancement and VCT conversion. See ATM . demultiplexing ( demultiplexer ) one input stream composed of a plurality of the multiplexed signal is converted back to a single Disconnect * Forced interruption of "telnet out " session A device that acts as a destination, source, or both. DTEs include devices such as multiplexers, protocol converters, and computers. A connection to a data network is a data communication device that uses a clock signal generated by the device DCE data communication device ( by JIA defined ) or a data circuit-terminating equipment ( according to ITU-T defined ) constituted by Disconnect * Forced interruption of "telnet out " session Sending CDP packets every 60 seconds ( every 60 transmits second cdp packet ) HoldTime 180 seconds ( per CDP information is saved 180 [ seconds ) Please refer to the second part of the CCNA Professional English Vocabulary Collection : Classic Recommendations ; CCNA Professional English Vocabulary Collection Network layer : routing ( path selection ), logical address (IP) Packet =========================================================== =============== IGRP uses composite metrics to select the best route . De discard Eligibility is used in the Frame Relay network to tell the switch if the switch is too UDP ( User Message Protocol ), no connection , no retransmission mechanism , unreliable transmission ATMM was ATM management (ATM Management) in ATM a protocol running on the switch tube =========================================================== =============== PPP: The convergence algorithm provides loop-free operation throughout the routing calculation. DUAL authorizes routers involved in topology versions that can be synchronized at the same time, and routers not involved are not affected by this change. See Enhanced IGRP . B (config-if) #ip nat inside configured S0 interface inside the network Used to connect to remote sites . The law finds a word. The device relaxes the requirements for a feature ( such as latency ) and tries to find a path that meets the most important needs of a group. Reliable transmission mainly involves physical addressing, line procedures, network topology, error notification, orderly delivery of frames, and flow control. The IEEE has further split this layer into a MAC sublayer and an LLC sublayer. Also known as the link layer. Can be compared to the data link control layer of the SNA model. See Application layer , LLC , MAC , Network layer , Physical Show users to see " who " login to local WAN type and encapsulation protocol : Enable enter privileged mode . 1 E-Channelized ( channelization E-1) operate in 2048Mb / s access to a link, a 29 th B The network node becomes the activity monitor and is responsible for managing tasks such as preventing loops and ensuring that tokens are not lost. ACL two actions : dial backup ( Dial Backup ) dial-up connection is typically used to provide redundancy backup frame relay connection. Backup chain Interface s 1 encapsulation frame-relay Piece address. The switch then filters the network with a known hardware address (MAC) Blocking -> Listening -> Learning -> Forwarding ADSU ATM data service unit (ATM Data Service Unit) is used by HSSI connection mechanism compatible IGRP uses a 24-bit metric . The root port does not participate in the competition of the specified port. 2) Usually all the interfaces of the root bridge are designated ports. First, a one-way virtual control connection (VCC) established by a LES to an LEC in the ATM . Usually, the VCC =========================================================== =============== buffer ( Buffer ) designed to store data processed in the transmission. Buffer for receiving / storage Telnet: Multi-person remote management ( depending on performance , number of VTY lines ). Not safe . Call setuptime ( call setup time ) affects the length of time required for switched calls between DTE devices B(config)#access-list 1 permit any A regional border router between an OSPF autonomous system and a non- OSPF network, operating OSPF and an additional routing protocol ( such as RIP) . The ASBR must be in a non-stub OSPF area. See ABR , non-stub area, and OSPF . Floating routes ( floating routers ) are used along with dynamic routing to provide backup routes to prevent failure. Set startup options. Class C network (C -based network ) portion of the Internet Protocol hierarchical addressing scheme. Class C network has 24 Hostname ABC configuration local username =========================================================== =============== Choose an agreement. Provide timing. ARA AppleTalk Remote Access (AppleTalk Remote Access) is built for Macintosh users =========================================================== =============== Interface ethernet 0/1 enters the Ethernet port numbered 1 in slot 0 . More details are configured. Allow multi-protocol support and interface configuration. In ABR service allows a congestion feedback mode. EFCI can be set by any network element in immediate or some kind of congestion state. The destination end system can perform a protocol that adjusts and lowers the cell rate of the connection based on the EFCI value. See ABBR . =========================================================== =============== Frame-relay switching CIDR stepless routing domain (Classless Interdomain Routing) stepless routing protocol =========================================================== =============== DDR demand dial routing (dial-on-demand routing) allows a router according to the sending station needs The metric is 32 bits long, the K values ​​are not equal , and the neighbor relationship cannot be created. The AS autonomous system is different , and the neighbor relationship cannot be created. At a rate higher than T1 , hello packet is sent every 5 seconds , at a rate lower than T1 . On , will send hello every 60s The designated router is in case of failure. Table or logical address table. . 1 T-chanelined ( channel of the channel T-1) operate in 1.544Mb / s one access link is 23 is th B channels Change type. Sometimes called modified cut-through . Configuration and beacon . BECN between the Explicit Congestion through-pipe (Backward Explicit Congestion Notification) BECN is ABM Asynchronous Balance Mode ---- ABM is an HDLC ( or a protocol derived from it ) communication technology that supports peer-to-peer, point-to-point communication between two stations when two stations can start transmitting. ! Boot ROM ( Boot ROM) for the router in order to release the boot mode router. Then guide Bus ( bus ) through a physical path ( usually wire or copper wire ) a digital signal can be used to calculate R14(config-if)#dialer idle-timeout 60 Debug ip igrp transactions debug igrp event content The PPP protocol is defined in RFC 1378 . See PPP . Connectionless ( no connection ) does not require the creation of data transfers from virtual circuits. It has no overhead, try its best Network devices ( such as routers, bridges or hubs ) efficacy. They serve as an FEP for an ATM network that uses a special DSU to complete the packet encapsulation . Different frequency and phase relationships. Asynchronous transfers typically encapsulate a single character in control bits ( called start and stop bits ) Configure ACL to reject london to ping through Denver (1) A technique for making more data. FRAME-RELAY also causes routing unreachability problems, ie horizontal separation rules. To solve the horizontal separation, you can use the sub-interface method. administrative weight ( administrative weights ) value for a given network administrator specified hierarchical network links. BUS BUS ----- in LAN emulation, responsible for parsing the broadcasting and with all the unknown ( unregistered ) packet into the address of the ATM hardware or software required for point to point virtual circuit. See LANE , LEG , LEGS, and LES . BX.25 AT&T 's use of X.25 . See X.25 . Scalability and improved performance and usability enhancements. choke packet ( packet that was blocked ) when congestion exists, it is sent to the sender of a packet, it should inform Interface serial 0 UTR Data Terminal Ready (Data Terminal Ready) ----- an activated with DCE communication There is a command line interface function. Show cdp interface serial 1 View the CDP information of the interface. Hostname ABC configuration local username Interface s 1.??? point-to-point enables a peer -to- peer subinterface . ??? is the interface number . ip add 10.1.1.1 255.255.255.0 configures the ip for the subinterface Set of special character data link communication protocols. These protocols have generally been replaced by bit-oriented protocols. Compare the bit-oriented protocol . cable range ( range of cables ) in the extended AppleTalk network,cisco ccie security v5 training, using the number range assigned to the existing nodes on the network. The value of the cable range can be a sequence of one or several consecutive network numbers. Node addresses are determined by their cable range values.
