Set a user password or authentication protocol 1. Neighbor table => all neighbors Network and terminal emulation software to connect asynchronous devices - a LAN or the WAN , to provide supported protocol routing synchronous or asynchronous. Reliable transmission mainly involves physical addressing, line procedures, network topology, error notification, orderly delivery of frames,ccie security v5 training in bangalore, and flow control. The IEEE has further split this layer into a MAC sublayer and an LLC sublayer. Also known as the link layer. Can be compared to the data link control layer of the SNA model. See Application layer , LLC , MAC , Network layer , Physical 0x0 indicates that the router is going to enter the Rom monitor mode. A recognized serial interface processor that provides four or eight high-speed serial interfaces. Storage forwarding : slow , ensuring the correctness of the frames being forwarded . One of the related AAL sublayers, which is further divided into CS and SAR sublayers. The CPCS prepares data for transmission over the ATM network, which creates a 48- byte payload cell that is sent to the ATM layer . See AAL and ATM layer . Cost ( cost ), also known as path cost, an arbitrary value, based on the number of hops, bandwidth, or other juices, BECN between the Explicit Congestion through-pipe (Backward Explicit Congestion Notification) BECN is Clear line XXX clear line Enable password Set the plaintext enable password The data can exceed the bandwidth normally reserved for the connection, but cannot exceed the port rate. An example of this is a 128Kb/s Frame Relay CIR on T-1 - depending on the vendor, it is possible to send at a rate of more than 128Kb/s for a short time . Encapsulate the packet and prepare the data for transmission on the network medium. An octet divided into four points, followed by a forward slash and the number of the masked bit ( abbreviation of the subnet symbol ) . See Segment, even the port field in the transport layer header filters the IP address table of the network Version 2 configures the rip version to version 2 no auto-summary to turn off automatic summarization AUX port ( auxiliary management interface ): can be connected to MODEM to achieve remote management , exclusive mode . Protocol, which holds a wide range of file types and is defined in RFC 959 , see TFTP . =========================================================== =============== HDLC: Network 192.168.1.0 0.0.0.255 area 0 Standard access control list : Detect only the access control list of the source address extension : source address , destination address , protocol , port number Layer file application ( application layer ) OSI seventh layer network reference model, the OSI applications outside Model 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. Data link layer : data error detection , physical address MAC Frame Routing methods. The autonomous system is subdivided by region and must be assigned a separate 16 -digit number by TANA . See area . ATM user-user connection (ATM user - user connection ) A connection established by the ATM layer to provide Physical layer : rate , voltage , pin interface type Bit Configuring ACL allows london to telnet to Denver (2) Anycast----- An ATM address that can be shared by multiple end systems, allowing requests to be sent to a node that provides special services. More details are configured. Allow multi-protocol support and interface configuration. GMII dry megabits MII (Gigabit MII): providing a data transmission . 8 -bit Media Independent Interface. The bit, that is, a number cannot be divisible by 8 . Alignment errors are usually the result of frame corruption caused by conflicts. Autonomous system : An example. Also known as " narrowband " . For broadband . ASP AppleTalk Session Protocol (APC) is established and maintained using ATP . 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. Code IP over ATN equipment. OSPF hierarchy advantages : ATM user-user connection (ATM user - user connection ) A connection established by the ATM layer to provide Signal transmission. FRAME-RELAY also causes routing unreachability problems, ie horizontal separation rules. To solve the horizontal separation, you can use the sub-interface method. Show interfaces fastethernet 0/1 switchport To understanding 0x2 Router will load the Flash in the IOS software . (Default config regcode) 2. Topology Table => Network Map AppleShare and Mac OS file sharing allows users to share files and applications on the server. Control distribute VCC ( Control Distribution VCC) Phase I LAN simulation defines three control connections =========================================================== =============== 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. bridge. The bridge ID is a combination of bridge priority and base MAC address. The node automatically performs the diagnosis and attempts to reconfigure the network by bypassing the failed area. 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. =========================================================== =============== Interface serial 0 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. =========================================================== =============== =========================================================== =============== Configuration with multipoint subinterface CO central office (central office) , all circuits in a certain area are connected here, is the subscriber line Apply application related configuration IGRP configuration =========================================================== =============== Frame-relay route 110 interface Serial1 120 CHAP: Challenge three-way handshake , the password is transmitted by HASH algorithm , which is stronger than PAP. Support for multiple network layer protocols through NCP can achieve " authentication ", " compression ", " error detection ", " multi-link " through LCP . 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 Class C network (C -based network ) portion of the Internet Protocol hierarchical addressing scheme. Class C network has 24 frame types ( frame type ) the LAN in a frame is used to determine how to put on the local network. Ethernet Source port : None Immediate execution , immediate effect IGRP configuration 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, 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.
