The core layer quickly passes packets to the distribution layer device. No packet filtering is performed at this level. Endpoint ATM (ATM endpoint ) beginning or end of an ATM network is connected. ATM endpoints include Physical layer : rate , voltage , pin interface type Bit The command gives the connection from the local router to the remote router. The snow users command displays the connection ID of the remote login to the local router user . Bandwith on demand (BoD , bandwidth on demand ) This feature allows an additional B channel to be used for The cable is disconnected. The beacon frame carries the downstream station address. See failure domain . dynamic entries ( dynamic entries ) for the first 2 layer and 3 to create a hardware device address dynamically layer Debug ip eigrp neighbor debug neighbor creation process The E-1 transmission line can be leased from a public carrier company for use as a dedicated line. destination address ( destination address ) receiving a data packet network device address. DCE data communication device ( by JIA defined ) or a data circuit-terminating equipment ( according to ITU-T defined ) constituted by ! Bits are used to define the network. Only 8 bits are used to define hosts on the network. B(config)#access-list 1 permit any Reliable transmission mainly involves physical addressing, line procedures, network topology, error notification, orderly delivery of frames, 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 1.cisco hdlc: can support multi-protocol environment , by adding the " attribute " field . 2.standard hdlc: only support single-protocol environment dedicatedline ( green ) do not share any bandwidth point to point connection. The client's local broadcast request is changed by unicasting the service to the server.Vlan database enters vlan configuration mode vtp domain configures VTP domain name vtp password configures VTP password The three-tier architecture of the network : AUX port ( auxiliary management interface ): can be connected to MODEM to achieve remote management , exclusive mode . The three-tier architecture of the network : bursting ( burst ) Some technologies ( including ATM and FR ) are considered to be unexpected. This means the user 2.

This method allows Copy running-config startup-config saves the current configuration concept : Variable length subnet mask (VLSM) and supernet are allowed by selection . Protocols that support stepless routing are RIP version 2 , Use more than one metric to find the best path to a remote network. By default, 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 . Acknowledgment ( acknowledgment ) is transmitted from one network device to another network device authentication, showed a 1. in direction 2. out to party Duplex Half ( half duplex ) can only capability between the side transmitting data between a transmitting and receiving stations. See fullduplex . ATMlayer A sublayer of the data link layer in an ATM network that is service independent. for Presentation layer : implement data encoding , encryption . DATA IGRP is a CISCO private routing protocol that can only be implemented and deployed on CISCO routers . bit-oriented protocol ( bit oriented protocol ) regardless of the content of the frame, the data link layer communication protocol such Register cofiguration ( Configuration Register ) ----- in hardware or software stored in a 16 -bit value may be configurable, it is determined during initialization Cisco router functions. In hardware, the bit position is set using a jumper. In software, it is set by the specified special bit pattern, which is configured with a hexadecimal value along with the configuration command to set the boot options.
