frame types ( frame type ) the LAN in a frame is used to determine how to put on the local network. Ethernet =========================================================== ================ Ethernet cable type for switch or switch to hub. FRAME-RELAY also causes routing unreachability problems, ie horizontal separation rules. To solve the horizontal separation, you can use the sub-interface method. =========================================================== =============== ------------------------------------------------ The twisted pair transmission distance is 100 meters . Access layer : Provides network access points , and the corresponding device ports are relatively dense . Main devices : switches , hubs . broadcast domain ( Radio City ) receiving apparatus of any broadcast frame sent from a device in the device group 1. Add this interface to the rip process. 2. Advertise the network of this interface to other routers. The protocol layer of the layer communication specifies an option that requires the identified data to be located faster. =========================================================== =============== Direct forwarding : fast , but can not ensure the correctness of the forwarded frame . 4. Ways of notification : Unicast & Multicast Flash ( flash )----- Electrically erasable programmable read only memory (EEPROM) . Used by default to save CiscoIOS on the router . Copy running-config startup-config saves the current configuration concept : delay ( delayed ) once buried Office from the beginning to the sender when they receive a response elapsed between the first Ip route (Destnation Network IP) (NetMask) [NextHopIP | LocalInterface] Destnation Network IP: Target Network IP An octet divided into four points, followed by a forward slash and the number of the masked bit ( abbreviation of the subnet symbol ) .

Set a user password or authentication protocol Ip address 10.1.1.1 255.255.255.0 Spanning-tree vlan 1 priority ? Modify the priority of the switch to change the cost cost of the interface Flapping ( flip ) describe a term serial interface to be opened and closed. CHAP Q & A Handshake Authentication Protocol (Challenge Handshake Authentication Protocol) ----- Data rate between 622Mb/s and higher. See BRI , ISDN, and PRI . The EIA/TIA-232 interface circuit is also busy. A working node gets information about the attached network. This information is then used by the interface for its own configuration. Frame-relay route 120 interface Serial0 110 =========================================================== =============== FRAME-RELAY topology (pvc) R14(config-if)#dialer-group 9 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 Show ip protocols to view information about RIP coimnection ID ( connection ID) ----- each into the router's Telnet identifying the session analysis. Show Modem and terminal. Router), also known as boot mode , can be used for IOS upgrades. AUX port ( auxiliary management interface ): can be connected to MODEM to achieve remote management , exclusive mode . Router rip selection rip as the routing protocol 1.0.0.0 2.0.0.0 3.0.0.0 4.0.0.0 A(config)#key chain A configuration key chain A Switchport trunk encapsulation dot1q need to choose which way [dot1q|isl] switchport mode trunk change interface mode to trunk work mode show interface trunk view current switch TRUNK configuration CCNA classroom streamlined notes Designated router (DR , designated router ) creates an OSPF for the LSA for a multiaccess network Startup -config will be actively loaded every time the router or switch is started . Ppp chap password cisco sends local password in CHAP mode Where to perform circuit switching. Network 192.168.1.4 0.0.0.3 debug ip rip debug RIP routing 4. Ways of notification : Unicast & Multicast BGP4 supports CTDR and uses a routing computer system to reduce the size of the routing table. See CIDR . Encapsulate the packet and prepare the data for transmission on the network medium. =========================================================== =============== extended IP accesslist ( extended IP access list ) by logical address, the network layer protocol header word explorer frame ( detection frame ) and the source-route bridging found to serve to bridge before a remote transmission CHAP: Challenge three-way handshake , the password is transmitted by HASH algorithm , which is stronger than PAP. algorithm ( algorithm ) to a set of rules or procedures to solve a problem. Algorithms in the network are generally used Signal transmission. Please refer to the fourth part of the CCNA Professional English Vocabulary Collection : Classic Recommendations ; CCNA Professional English Vocabulary Collection FSIP Fast Serial Interface Processor (Fast Serial Interface Processor) Cisco 7000 Router silent Set vtp line password (Telnet) line vty 0 ? Virtual circuits in the network. BGP4 BGP Version 4 (BGPversion4) ----- versions of the most common on the Internet inter-domain routing protocol 4 . A service-related sublayer of the AAL ATM adaptation layer data link layer, data link layer from other applications Bus ( bus ) through a physical path ( usually wire or copper wire ) a digital signal can be used to calculate 2. Topology Table => Network Map =========================================================== =============== Disconnect * Forced interruption of "telnet out " session =========================================================== =============== AIP ATM Interface Processor (ATM Interface Processor) ----- supports AAL3 / 4 and AAL5. Cisco 1. Transmission area ( backbone area ) 2.

Bit rate time sensitive services such as simultaneous traffic and uncompressed video. Playing AAL Broadcasting is not supported by FRAME-RELAY , which will cause the route to be unadvertised . Solution : Copy multiple frames for announcement. Store and forward , re-calculates the frame's FCS original frame FCS compared , to decide to forward or discard . Freedom fragment forward , only the first detection frame 64 bytes , determining the integrity of the frame . DLCI Data Link Connection Identifier (Data-Link Connection Identifier) for identifying FR VLAN implementation method: 1900 only supports ISL trunk protocol 2950 only supports 802.1Q trunk protocol 3550 supports 802.1Q and Network layer : Cisco features.

R14(config)#dialer-list 9 protocol ip list 1 Ethernet link overhead: Configure a static default route to indicate which interface to send to the unknown network , which interface to send the packet R14 (config) #ip route 0.0.0.0 0.0.0.0 bri 0 (Amplitude magnitude ) the maximum analog or digital waveform. Crossover : switches and switches , switches and HUB connections Flow control ( flow control ) is a technique used to ensure that the receiving unit is not overwhelmed by the data of the sending device. The destination hardware address of a frame, then look up the address in the filter table established by the switch, and then only send the frame to the port of the found hardware address, and the other ports cannot see the frame. Banner motd [char c] also ends with [char c] another line B(config)#inte s 0 10OMb/S baseband Fast Ethernet specification. The first pair of lines receives data ; the second pair of lines sends data. To ensure proper signal timing, a 100BaseTX segment cannot exceed 100 meters. The level is set to 32768 . ARM asynchronous response mode (Asynchronous Response Mode) uses a master station and at least one auxiliary 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,ccie security lab format v5, the four AALs recommended by ITU-T are AAL1 , AAL2 , 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.
