DDR is allowed through a modem or an external ISDN terminal adapter Show ip protocols to view information about RIP coimnection ID ( connection ID) ----- each into the router's Telnet identifying the session analysis. Show Modem and terminal. Router), also known as boot mode , can be used for IOS upgrades. AUX port ( auxiliary management interface ): can be connected to MODEM to achieve remote management , exclusive mode .

Ppp chap password cisco sends local password in CHAP mode Where to perform circuit switching. Network 192.168.1.4 0.0.0.3 debug ip rip debug RIP routing 4. Ways of notification : Unicast & Multicast BGP4 supports CTDR and uses a routing computer system to reduce the size of the routing table. See CIDR . Encapsulate the packet and prepare the data for transmission on the network medium. =========================================================== =============== extended IP accesslist ( extended IP access list ) by logical address, the network layer protocol header word explorer frame ( detection frame ) and the source-route bridging found to serve to bridge before a remote transmission CHAP: Challenge three-way handshake , the password is transmitted by HASH algorithm , which is stronger than PAP. algorithm ( algorithm ) to a set of rules or procedures to solve a problem. Algorithms in the network are generally used Signal transmission.

Bit rate time sensitive services such as simultaneous traffic and uncompressed video. Playing AAL Broadcasting is not supported by FRAME-RELAY , which will cause the route to be unadvertised .

Crossover : switches and switches , switches and HUB connections Flow control ( flow control ) is a technique used to ensure that the receiving unit is not overwhelmed by the data of the sending device. 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. Banner motd [char c] also ends with [char c] another line B(config)#inte s 0 10OMb/S baseband Fast Ethernet specification. The first pair of lines receives data ; the second pair of lines sends data. To ensure proper signal timing, a 100BaseTX segment cannot exceed 100 meters. The level is set to 32768 . ARM asynchronous response mode (Asynchronous Response Mode) uses a master station and at least one auxiliary 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,ccie security lab format v5, 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.
