An example. Also known as " narrowband " . For broadband . A Cisco hierarchical network. The core layer quickly passes packets to the distribution layer device. No packet filtering is performed at this level. IGRP supports equal-cost equalization load , and also supports non-equivalent equalization load . The process number does not affect the OSPF notification learning A series of actions performed immediately to determine if a connection request violates the QoS guarantee for establishing a connection . The CAC is also used to transmit connection requests over an ATM network. Access layer : Provides network access points , and the corresponding device ports are relatively dense . Main devices : switches , hubs . bridge priority ( bridge priority ) disposed bridge STP priority. By default all bridges take precedence There is a command line interface function. Dynamic NAT configuration Static NAT configuration Spanning-tree vlan 1 cost ?? The main path of traffic. Bypass relay ( bypass relay ) enables an interface of the token ring to be closed and effectively detached from the ring Network and terminal emulation software to connect asynchronous devices - a LAN or the WAN , to provide supported protocol routing synchronous or asynchronous. Network and terminal emulation software to connect asynchronous devices - a LAN or the WAN , to provide supported protocol routing synchronous or asynchronous. 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 Transport layer : CIP channel interface processor (Channel Interface Processor) ----- Cisco 7000 a channel series routers use additional interface, which is connected to a host computer a control device. This device eliminates the need for an FBP connection channel. bridge. The bridge ID is a combination of bridge priority and base MAC address. DSAP destination point energize business (Destination Service Access Point) a network node of business routing Classless ( stepless routing ) transmits routing update routing subnet mask. Stepless road Typically specified by the network administrator and used by routing protocols to compare different routes through an internetwork. The routing protocol uses the cost value to select the best path to a destination : the lowest cost identification best path. See routing metnC . Bus ( bus ) through a physical path ( usually wire or copper wire ) a digital signal can be used to calculate fault tolerance ( fault-tolerant ) network device or the communication link may fail without interrupting communications degree. Fault tolerance 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 CCNA is Cisco's most basic entry certification. Among them, the test focuses on network concepts and theories. For beginners, 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,ccie security sample lab, I believe that learning will definitely do more with less.
