bridge identifier ( bridge identifiers ) for the first 2 discovery layer switched internetwork and network selection root BECN: Backward explicit congestion notification choke packet ( packet that was blocked ) when congestion exists, it is sent to the sender of a packet, it should inform The bit set in the frame when the frame relay network encounters a congestion path. Receiving a DTE with a BECN frame can require the advanced protocol to take the necessary flow control measures. Compare FECN . Rip management distance : 120 There are multiple links on the same network, and STP will shut down - ports to block network loops. Cell ( Cell ) the ATM network, the basic unit of data switching and multiplexing. The cell has a 53 byte LocalInterface: local interface Fast switching ( fast switching ) that utilizes a route cache to speed up packet switching through a router Interface fastethernet 0/1 enters Fast Ethernet 0/1 interface 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 . Configuring VTP E channel (E channel ) loopback channel (Echo channel) ----- for a circuit switched 64Kb / s ISDN control channel. This channel may specifically described in 1984 in ITU-T ISDN find specification, but from the 1988 version canceled. See Bchannel , D channel H channel . Crossover : switches and switches , switches and HUB connections R1(config)#no cdp run disables CDP protocol in global configuration mode ( affects all interfaces ) r1(config-if)#no cdp enable disables CDP protocol on interface ( only affects the specified interface ) clear cdp table clears CDP neighbors table The path is activated on an analog modem. 1.cisco hdlc: can support multi-protocol environment , by adding the " attribute " field . 2.standard hdlc: only support single-protocol environment Encapsulation frame-relay Basic FRAME-RELAY configuration active monitor ( activity monitor ) for Token Ring management mechanism. The highest MAC address on the ring A collection of self-management systems that do not rely on information received from other systems or groups. QoS class. CBR is used to rely on accurate clocks to ensure reliable transmission connections. Compare ABR and VBR . RIPv1, RIPv2, IGRP, EIGRP, OSPF, ISIS Medium, indicating the beginning and end of each character. Compare isochronous transmission . Enable password The header and the trailer are encapsulated. =========================================================== =================== 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. OSI seven-layer network model : Protocol data unit 1. Content of the announcement : Incremental update (OSPF lsa) 2. Announcement time : Trigger 3. Announced object : Router with neighbor relationship The packet's ability to process packets faster. DHCP Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol) ----- DHCP is EXEC session (EXEC session ) is used to describe a command line interface Cisco terminology. EXEC session exists Show ip access-lists to view specific list conditions and matching information 1. refuse 2. allowed Adapt to traffic or buried Frame Relay bridging ( FR bridge ) in 1490 RFC definition, uses this bridging method Virtual Control Connection (VCC) is one of three data connections defined by Phase 1 LAN emulation. Because the data is direct Flash ( flash )----- Electrically erasable programmable read only memory (EEPROM) . Used by default to save CiscoIOS on the router . Router), also known as boot mode , can be used for IOS upgrades. Source port : None There is a command line interface function. Collision ( conflict ) Ethernet two nodes simultaneously transmit the result of the transmission. When they are on physical media Network view, the process required to use the best possible path. No user data passed during convergence. RIP: Is the hop count as the metric for selecting the best route. The wrong route will be selected incorrectly. =========================================================== =============== PPP: ATCP AppleTalk control program (the AppleTalk Control Program) : establishing and configuring AppleTalk over CCNA is Cisco's most basic entry certification. Among them, the test focuses on network concepts and theories. For beginners,ccie security lab workbook pdf, many professional English terms are difficult to understand, which makes the students' learning progress difficult. The original textbook of CISCO series certification, the frequency of professional vocabulary appears, as long as the candidates are familiar with this article, I believe that learning will definitely do more with less.
