The highest MAC address on the ring Storage forwarding : slow , ensuring the correctness of the frames being forwarded . Guide IOS and how to configure it. The router of the DCE needs to configure the clock frequency. IGRP is a CISCO private routing protocol that can only be implemented and deployed on CISCO routers . =========================================================== =============== HUB Hub : A broadcast domain, a collision domain. Flooding forwarding . Shared bandwidth . Straight line : the host and switch or HUB connected =========================================================== =============== 1.Down 2.Init 3.Two-Way 4.ExStart =========================================================== =============== Whether a given node ID in an AppleTalk network is used by another node. If the node ID is used at the end, the sending node can use the ID of that node . If the node ID is already used, the sending node will select a different ID and send more AARP probe packets. See AARP frame tagging ( frame flag ) see Frame Identification . Servers, workstations, ATM- to- LAN switches, and ATM routers. IGRP is a distance vector type routing protocol that does automatic route summarization . There is no way to turn off this feature . Adapt to traffic or buried CDP Cisco Discovery Protocol (Cisco Discovery Protocol) Cisco proprietary protocol, used to tell the neighbor 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 . Frame-relay switching Track all possible paths to a given destination. Also known as a full ring detection package. See explorer packet , local explorer packet, and Spanning explorer packet . ------------------------------------------------ When they meet, the frames of each node collide and are damaged. See collision domain . Physical layer : rate , voltage , pin interface type Bit Backbone ( backbone ) basic part of the network, which provides sent to other networks and other networks originating from destination address ( destination address ) receiving a data packet network device address. switchport access vlan 10 Add this port to 10 VLAN in . Surgery. The IBM network is called pacing, meaning that when the receive buffer is full, a message is transmitted to the sending unit to suspend transmission until all data in the receive buffer is processed and the buffer is ready to receive again. NetMask: target network subnet mask ITU-T standard. Currently BISDN uses ATM technology and SONET- based transmission circuits to provide 155Mb/s and Exit application and exit the database configuration mode of the VLAN 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 . B(config)#inte s 1 Rate enhancement and VCT conversion. See ATM . The switch, Cisco calls it a switch-fabric . The switches in the switch fabric must keep track of the frames received on that switch port and must track the frames they belong to as they pass through the switch fabric. Checksum ( checksum ) ----- ensure the integrity of the transmission data for testing. It is through - a number calculated from a string value series of mathematical functions. It is usually placed at the end of the calculated data and then recalculated at the receiving end for confirmation. Compare CRC . The reduced mode IP multicast scheme uses TGMP to transport routing datagrams between its neighbors. See IGMP . PPP configuration Router ospf 1 BECN: Backward explicit congestion notification Medium, indicating the beginning and end of each character. Compare isochronous transmission .

Protocol): A test of connectivity between two AppleTalk nodes, where one node sends a packet to another node and receives a response or copy in response. Show interfaces fastethernet 0/1 switchport ATM ATM (Asynchronous Transfer Mode) by a fixed-length 53 -byte element identifier 1. Control network traffic 2. Implement packet filtering ACL is the most important : The ACL condition list will have a condition of hiding " reject all " at the end .

Routers running BGP ; they use a TCP port on layer 4 of the OSI Reference Model . Especially using TCP CGMP Cisco Group Management Protocol (Cisco Group Management Protocol): made Cisco a proprietary protocol developed. The router uses CGMP to send multicast member commands to the Catalyst switch. The BPDU is exchanged between switches every two seconds. Periodic.

EXEC session (EXEC session ) is used to describe a command line interface Cisco terminology. EXEC session exists ATG Address Translation Gateway (Address Translation Gateway) ----- Cisco DECnet routing software is a mechanism that allows the router route multiple, independent DECnet networks and to establish a user-specified address into a network between the selected nodes. BPDU: Bridge Protocol Data Unit Bridge Protocol Data Unit Show ip ospf interface serial 1 View the process ID of RouterID and OSPF and the associated network type . show ip protocols DHCP Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol) ----- DHCP is It enables two socket (Socket) can be reliably performed between transactions, wherein a request for another execution of a given task and to report the results. ATP grabs both the request and the response, ensuring that the request - response is exchanged without loss. In attenuation ( attenuation ) communication, the weakening or loss of signal energy, usually caused by distance. Access-list 1 deny host 10.3.3.1 access-list 1 permit any Interface Serial1 no ip address Medium is classified by channel with a bandwidth greater than 4 kHz ( typical voice level ) . It uses simulation in LAN technology ATMARP server (ATMAPR server ) provides a logical subnet to run the address resolution service. DLSw+ Cisco 's DLSw implementation supports the RFC standard, and Cisco added the goal to increase VTP is the use multicasting to advertise, VTP will intervals . 5 minutes announcement once , even if there is no change .VTP switch synchronized the last configuration . The switch will first cache the frame source address. It enables two socket (Socket) can be reliably performed between transactions, wherein a request for another execution of a given task and to report the results. ATP grabs both the request and the response, ensuring that the request - response is exchanged without loss. In attenuation ( attenuation ) communication, the weakening or loss of signal energy, usually caused by distance. Experiment : Network and terminal emulation software to connect asynchronous devices - a LAN or the WAN , to provide supported protocol routing synchronous or asynchronous. The requested VCC determines the likelihood of a path containing the appropriate bandwidth. data circuit-terminating equipment ( data circuit terminating equipment ) the DCE is used between DTE equipment 1.

FSIP Fast Serial Interface Processor (Fast Serial Interface Processor) Cisco 7000 Router silent Available in four different frame types. They are not compatible with each other, so for two hosts to communicate, they must use the same frame type. The three-tier architecture of the network : NetMask: target network subnet mask The network node becomes the activity monitor and is responsible for managing tasks such as preventing loops and ensuring that tokens are not lost.
