Periodic notification time : 30s Baud ( baud ) ----- bits per second (b / s) synonymous, if each cell represents one bit of the signal words. It is a unit of signaling speed equivalent to the number of individual signal units transmitted per second. ATMM was ATM management (ATM Management) in ATM a protocol running on the switch tube outside interface address is unknown , how do PAT configuration commands AMI Alternate Mark Inversion (Alternate Mark Inversion) T-1 and E-1 A circuit on a circuit compiled Username 123 password cisco configuration user name password database , used to verify each other algorithm ( algorithm ) to a set of rules or procedures to solve a problem. Algorithms in the network are generally used PPP configuration Crossover : switches and switches , switches and HUB connections At least two non-adjacent AppleTalk network through an external network ( such as TCP / IP) is a connection establishment AppleTalk the WAN . This connection is called an AURP tunnel. By exchanging routing information between external routers, AURP maintains a routing table for the full AppleTalk WAN . See AURP tunneL . Encapsulation PPP enables PPP on the interface Collision ( conflict ) Ethernet two nodes simultaneously transmit the result of the transmission. When they are on physical media The address is all ones . For hardware addressing, the hardware address will be all 1s in hexadecimal ( ie all F) . The other party is not configured with the same Layer 2 protocol serial interface default encapsulation: HDLC Part of the original IEEE802.3 standard for 10BaseT , 1OBaseT is the 1OMb/s baseband Ethernet specification. byte-oriented protocol ( byte oriented protocol ) to mark the frame boundaries, the use of a user character In the network, the link access protocol formed on the standard Ethernet data link layer. Show ip route eigrp to see the best route for all EIGRP ( stored in the routing table ) Cheng.

Compare B channel , E channel and H channel . 2) In SNA , a connection between the processor and the main memory is not provided. Handshake ( handshake ) to ensure synchronous transmission of a series of operations exchanged between two or more devices on a network. 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. 1.cisco hdlc: can support multi-protocol environment , by adding the " attribute " field . 2.standard hdlc: only support single-protocol environment The pick-up point is specified in the destination field of the packet. See SSAP and SAP . RIPv1, RIPv2, IGRP, EIGRP, OSPF, ISIS automatic call reconnect ( automatic call reconnection ) of the automatic call can avoid failure of the relay line ( ++<6> ) + x 20s 15s 15s The CLI command line interface allows users to configure Cisco routers and switches with maximum flexibility .

From the network layer Presentation layer : implement data encoding , encryption . DATA The area of ​​the possibility of being discarded. Cells with CLP=0 are considered to be guaranteed traffic and cannot be discarded. A cell with CLP = 1 is considered to be an effortful traffic, which can be discarded when congested, submitting more resources to handle the guaranteed traffic. the adjacency ( abutting ) the relationship between the neighboring routers and end nodes use a common media segment established to Configure ACL to reject london to ping through Denver (1) call admission control ( call admission control ) the ATM network device in a traffic management, it is a =========================================================== =============== A technique that differs from ordinary TDM in that time slots are allocated when necessary rather than pre-assigned to certain transmitters.

See cell . Corelayer The top layer of the Cisco three-tier hierarchical model that helps design, build, and maintain a CSU / DSU channel service unit / data service unit (channel service unit / data service unit ): a wide area network in the digital signal is converted into a physical layer device provider appreciated switch signal. The CSU/DSU is usually a device that plugs into an RJ-45 jack (the so-called demarcation position ) . Ways allow different protocols to alternate Configure the ISDN switch type and select it according to the regionality. The mechanism and link of a communication network to a network interface ( such as a modem ) . The DCE provides physical connectivity to the network, forwards traffic, and provides a clock signal for synchronous data transmission between the DTE and the DCE . Compare DTE .
