The number of hops added to a particular network, which converges slowly. To avoid this problem, various solutions have been implemented for each different routing protocol. These solutions include defining a maximum number of hops ( defined infinite ) , route balancing, poison reversal, and split horizon. A system developed to provide network security. See the authentication . Authorization and accounting 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 . Ip address 1.1.1.1 255.0.0.0 Configure the IP address of the interface D channel (D channel ) 1) data channel ----- a full duplex, 16Kb / S (BRA) or 64Kb / s (PRI) vlan 10 name cisco create a named CISCO 's 10 Hao VLAN vlan 20 create a system of self-named 20 Hao VLAN Copy tftp: startup-config copy flash: tftp: There is traffic successfully reaching the destination. This usually occurs in networks that combine inefficient or poorly cached routers with poor packet drop or ABR congestion feedback mechanisms. Encapsulate the packet and prepare the data for transmission on the network medium. =========================================================== =============== Free Fragment Forwarding (cisco private technology ): between pass-through forwarding and storage forwarding performance . The switch will first cache the frame source address. excess burstsize ( over burst size ) users may exceed the number of committed traffic burst size. 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 . Store and forward , re-calculates the frame's FCS original frame FCS compared , to decide to forward or discard . Freedom fragment forward , only the first detection frame 64 bytes ,ccie security v5 study guide, determining the integrity of the frame . The rated throughput of a network protocol or medium. Packet Exchange : X.25, Frame-Relay, ATM A remote AppleTalk location access protocol for resources and data. bandwidth ( the bandwidth ) the spacing between the highest and lowest frequency of signals used in the network. Usually, it involves one Frame Relay ( FR ) ----- the X.25 protocol ( a guaranteed unrelated packet relay data transmission techniques ) in a more effective alternative. Frame Relay is an industry-standard, shared, and best-effort switched data link layer package that provides multiple virtual circuits and protocols between connected mechanisms. cell payload scrambling ( cell payload scrambling ) the ATM switches and certain of the edges speed relay Change type. Sometimes called modified cut-through . And make console configuration settings. 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.
