Telnet: Multi-person remote management ( depending on performance , number of VTY lines ). Not safe . Using PPP encapsulation and support on the wire, it is a security feature that identifies the remote end and helps prevent unauthorized users. After the CHAP is executed, the router or the pick-up server determines whether a given user is allowed to access. It is a new, more secure protocol than PAP . Compare PAP . RA: An interface processor used by the device to provide two lOOMb/s lOOBaseT ports. Floating routes ( floating routers ) are used along with dynamic routing to provide backup routes to prevent failure. 1. Control network traffic 2. Implement packet filtering administrative distance ( management distance ) from 0 to 255 a number between, which represents one routing information AIP ATM Interface Processor (ATM Interface Processor) ----- supports AAL3 / 4 and AAL5. Cisco A feature that changes routing. B(config)#inte s 1 Layer file application ( application layer ) OSI seventh layer network reference model, the OSI applications outside Model Duplex Auto ( automatic duplex ) of a layer and 2 a device layer disposed on, it automatically switches provided Sending CDP packets every 60 seconds ( every 60 transmits second cdp packet ) HoldTime 180 seconds ( per CDP information is saved 180 [ seconds ) FRAME-RELAY also causes routing unreachability problems, ie horizontal separation rules. To solve the horizontal separation, you can use the sub-interface method. Route the path of the bridged network. Provide timing. guard band ( guard band ) two communication channels between a frequency region not used to provide the necessary space to avoid interference therebetween. address resolution ( ARP ) to resolve the differences between computer addressing scheme of the process. Address resolution VLAN; all switches in the end-to-end \VLAN understand all configured VLANs . End-to-end VLANs are configured to allow membership based on functions, projects, departments, and so on. Frame-relay map ip 10.1.1.2 110 broadcast for manual static mapping It does not indicate an error and can be intentional. See fragmentation . H channel (H channel ) high-speed channel (high-speed channel): a full-duplex, the 384Kb / s work on rate ISDN primary rate channel. See B channe , D channel , and E channel . Password cisco sets a password to "cisco" 10Gbps 2 1. Address Learning Address learing 2. forwarding / filtering decisions Forward / Filter Decision 3. loop avoidance Loop avoidance Use more than one metric to find the best path to a remote network. By default,ccie security lab setup, both IGRP and EIGRP use the bandwidth and latency of the line. However , the reliability of the Maximum Transmission Unit (MTU) , load, and link can also be used . Target : 172.16.3.1 Address learning, forwarding filtering, etc. of the switch : Create a standard 5 sub-section ATM cells. The ATM layer receives 48- byte segments from the AAL and appends a 5- byte header to each segment . These cells are then sent to the physical layer for transmission over the physical medium. See AAL . bursting ( burst ) Some technologies ( including ATM and FR ) are considered to be unexpected. This means the user B(config)#ip nat inside source list 1 interface serial 1 overload Show cdp neighbors detail View CDP neighbors ( including Layer 3 IP addresses ) show cdp entry * View CDP neighbors ( including Layer 3 IP addresses ) AAL3/4 ATM Adaptation Layer 3/4 One of the four AALs recommended by ITU-T , supporting connection-oriented and also support ESF extended superframe (Extended Superframe) of 24 composed of frames, each frame of 192 bits , the first 193 than The distance limit of each segment of 1OBaseT is about 100 meters. See Ethernet and IEEE 802.3 . Packet Exchange : X.25, Frame-Relay, ATM The other party does not have no shutdown to activate the port. bridge identifier ( bridge identifiers ) for the first 2 discovery layer switched internetwork and network selection root ASICs for integrated circuit applications ----- used for the first 2 layer switches filtering decision. ASIC view The clock frequency Serial1 is up, the line protocol is up interface is working properly. compression ( compression ) with a string of numerals repeated data, transmitted over a link than the normal grant End exit the interface And make console configuration settings. Network 192.168.1.4 0.0.0.3 CHAP: Challenge three-way handshake , the password is transmitted by HASH algorithm , which is stronger than PAP. DLSw+ Cisco 's DLSw implementation supports the RFC standard, and Cisco added the goal to increase The IP address is converted to a MAC address. See RARP . analog transmission ( analog transmission ) represented by different combinations of the information signal amplitude, frequency and phase Listen for digital signals on the cable before. In addition, the CSM elbow CD allows all devices on the network to share the same cable, but one at a time. If both devices are sending at the same time. A frame collision will occur and an interference pattern will be sent, the device will stop transmitting, wait for a predetermined amount of time, and then try to send again. Please refer to the fourth part of the CCNA Professional English Vocabulary Collection : Classic Recommendations ; CCNA Professional English Vocabulary Collection ! It consists of a router or access server or several routers or access servers, using inter-access tables and other methods to ensure the security of the private network. dixed configuration router ( fixed router ) can not be used to upgrade any new interfaces of the router. =========================================================== =============== explorer frame ( detection frame ) and the source-route bridging found to serve to bridge before a remote transmission Adopt standard : Or hub port duplex. Authorityzone ( authority zone ) part of the domain tree, the domain name tree and a name server are authoritative B(config)#inte s 1 IGRP is a distance vector type routing protocol that does automatic route summarization . There is no way to turn off this feature . Mesh Full ( full mesh ) network topology, wherein each node to other network nodes or virtual physical The quantity manages a QoS parameter specified when the connection is established . In CBR transmission, the degree of allowable fluctuation of data sampling by PCR is determined by the CDVT . See CBR and PCR . Duplex Half ( half duplex ) can only capability between the side transmitting data between a transmitting and receiving stations. See fullduplex . Each network segment elects a designated port BridgeID Lowest Show cdp interface serial 1 View the CDP information of the interface. Port Auxiliary ( auxiliary port ) the Cisco console port on the router backplane, which allows the call routing When they meet, the frames of each node collide and are damaged. See collision domain . 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. =========================================================== =============== A(config-keychain)#key 1Configure key 1 A(config-keychain-key)#key-string cisco define password A(config-keychain-key)#exit BGP failure domain ( fault domain ) ----- area of the failed token ring. When a station gets a serious fault ( such as a cable disconnection on the network ) , it sends a beacon frame that includes the fault reported by the station, its NAUN, and everything in between. This defines the fault domain. The beacon then begins the so-called automatic configuration process. See autore 1. When CISCO CATALYST series switches , at initialization , found no " user profile " when the file , will automatically load the Default Settings ( default configuration ) file , a switch for initialization . To ensure that the switch is working properly .2.
