ATM endpoints include The cable is disconnected. The beacon frame carries the downstream station address. See failure domain . Scalability and improved performance and usability enhancements. 1.Down 2.Init 3.Two-Way 4.ExStart =========================================================== =============== fault tolerance ( fault-tolerant ) network device or the communication link may fail without interrupting communications degree. Fault tolerance Show interfaces fastethernet 0/1 switchport AAL1 ATM Adaptation Layer 1 One of the four AALs recommended by ITU-T for connection-oriented, constant The process of outputting a single stream. See multiplexing . Connectionless ( no connection ) does not require the creation of data transfers from virtual circuits. It has no overhead, try its best 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 Dynamic routing ( dynamic routing ) network revision. Also known as " adaptive routing " , this technology is self- Adapt to traffic or buried IOS Cisco Cisco Internetwork Operating System Software (Cisco Internetwork Operating System software) ----- as CiscoFusion provide the functionality shared by all products in the off-line configuration, scalability and security of Cisco core routers and switches series. See CiscoFusion . =========================================================== =============== The path is activated on an analog modem. The client's local broadcast request is changed by unicasting the service to the server.Create a VLAN A method of maintaining framing on an interface (T-3 or E-3 circuit ) . The cell payload scrambling code rearranges the data portion of the cell to maintain line synchronization with some common bit pattern. An interface processor used by the device to provide two lOOMb/s lOOBaseT ports. Banner motd [char c] also ends with [char c] another line Ppp chap password cisco sends local password in CHAP mode Protocol : ICMP (Internet Control Message protocol) D channel (D channel ) 1) data channel ----- a full duplex, 16Kb / S (BRA) or 64Kb / s (PRI) Rip : Router information protocol ROM: Rom monitor is a lower-level os system than Mini IOS , similar to BIOS Mini IOS (2500 serial Spanning tree port Encryption ( encryption ) converting the information into a form clutter to effectively disguise, so as to prevent an authorized end Encryption ( encryption ) converting the information into a form clutter to effectively disguise, so as to prevent an authorized end A LAN standard that can run at speeds up to 200 Mb/s and use token transfer media access technology on fiber optic cable. For redundancy, a double loop structure can be used. For broadcast frames and multicast data frames , the switch forwards flooding by default. Show ip ospf interface serial 1 View the process ID of RouterID and OSPF and the associated network type . show ip protocols Show cdp neighbors to view CDP neighbors ( without IP) OSPF uses IP packets for route advertisement and learning , Protocol Number : 89 Redundant topology , causing " broadcast storm ", " multiple frame reception ", "MAC address table instability ". =========================================================== =============== Routing on ISDN or telephone lines. 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 Flapping ( flip ) describe a term serial interface to be opened and closed. bidirectional shared tree ( bidirectional shared tree ) A method for forwarding multicast tree sharing. This method allows 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) . Holdtime CDP (CDP hold time ) routers to keep from neighboring routers received Cisco Discovery Protocol ANSI is a member of the IEC and ISO . cell payload scrambling ( cell payload scrambling ) the ATM switches and certain of the edges speed relay =========================================================== ================ Show controllers serial 0 is used to view the attributes of DCE and DTE Is a point-to-multipoint connection. See control directVCC . Reduce the send rate. Encapsulation frame-relay Grafing ( transplanted ) to activate a pruning process had been frozen interface process. It is sent to the router A method of transmitting a parity bit or word in the link overhead of a previous block or frame. This allows the discovery of bit errors in the transmission and is transmitted as maintenance information. Circuit Switching : PPP, HDLC, SLIP DCE/DTE only exists in the WAN Holdtime CDP (CDP hold time ) routers to keep from neighboring routers received Cisco Discovery Protocol Switch function: 1. refuse 2. allowed When to disconnect =========================================================== =============== Other bridges operate the same spanning tree algorithm, but allow packet encapsulation to be transmitted over a Frame Relay network. B (config-if) #ip nat inside configured S0 interface inside the network The designated router is in case of failure. =========================================================== =============== Router, which is required for other special tasks in OSPF operations. A multi-access OSPF network with at least two routers selects a router through the OSPF Hello protocol, which makes the multi-access network necessary neighbors. DCE/DTE only exists in the WAN Encapsulation PPP enables PPP on the interface ATM ATM (Asynchronous Transfer Mode) by a fixed-length 53 -byte element identifier congestion avoidance ( congestion avoidance ) to minimize latency, the ATM network for controlling the system into dedicatedline ( green ) do not share any bandwidth point to point connection. CCNA classroom streamlined notes Fast Ethernet ( Fast Ethernet ) ---- speed lOOMb / s Ethernet specification. Fast Ethernet ratio Where to perform circuit switching. 5.ExChange 6.Loading 7.Full The command gives the connection from the local router to the remote router. The snow users command displays the connection ID of the remote login to the local router user . Part of the computer sends data to another part. ATMM was ATM management (ATM Management) in ATM a protocol running on the switch tube 1. Bandwidth 2. Delay 3. Reliability 4. Load 5. MTU The process of segmenting a packet into small pieces. The number of connections is reduced, thereby reducing the amount of plant routing traffic and the actual size of the database. 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 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 . Router), also known as boot mode ,ccie security v5 experience, can be used for IOS upgrades. AFP AppleTalk Filing Protocol (AppleTalk Filing Protocol) a presentation layer protocol support Router), also known as boot mode , can be used for IOS upgrades. show vtp status view VTP status VLAN implementation method: Ripv2 certification : R14(config)#interface bri 0 VLAN characteristics Basic FRAME-RELAY configuration Direct forwarding : fast , but can not ensure the correctness of the forwarded frame . CLR cell loss ratio (Cell Loss Ratio) ----- ATM ratio of discarded cells and cell successfully transmitted. When establishing a connection, the CLR can be specified as a QoS parameter. Enable enter privileged mode EIGRP and OSPF . Choose an agreement. Apply application related configuration =========================================================== =============== NextHopIP: Next hop IP ASBR autonomous system boundary router (Autonomous System Boundy Router) one on CSMA / CD carrier with Collision Detection Sense Multiple Access (Carrier Sense Multiple Access / Collision Detect ) Ethernet IEEE802.3 a technology committee defined. Every device is sending Bit ( bit, bit ) A number ; a 1 or a 0 . 8 bits make up one byte. Programs ( such as email or file transfers ) to provide services. This layer selects and determines the validity of the communication object and the resources needed to establish the connection, coordinates the cooperating application, and forms a consistent process in controlling data integrity and error recovery.
