CTD Cell Transfer Delay (Cell Transfer Delay) for ATM a given connection is used in the source classful routing ( hierarchical routing ) does not transmit the subnet mask information when sending routing update routing Provide sufficient management and configuration to get the router working so that someone can remotely log in to the router and configure it. =========================================================== =============== Rip management distance : 120 broadcast domain ( Radio City ) receiving apparatus of any broadcast frame sent from a device in the device group B(config-if)#ip nat outside configure S1 interface for the outside network to specify which hosts can NAT HUB Hub : A broadcast domain, a collision domain. Flooding forwarding . Shared bandwidth . Straight line : the host and switch or HUB connected 1. The content of the announcement : a copy of the routing table (copy) 2. The time of the announcement : periodicity 3. The object of the announcement : the directly connected neighbor router DCE data communication device ( by JIA defined ) or a data circuit-terminating equipment ( according to ITU-T defined ) constituted by The protocol field, even the direct font size in the transport layer header, filters the IPX address table of the network . =========================================================== =============== FRAME-RELAY topology (pvc) ACL for packet processing : =========================================================== ===================== AFI privilege and format identifier (Authority and Format Identifier) ​​A part of the NSAP ATM address The minimum information transmission rate agreed by the Frame Relay network, measured in b/s . The process of packaging or inclusion. In the OSI reference model, when data flows down the protocol stack, each layer encapsulates its next layer. Note : By default , all ports are subordinate to vlan 1 ( management VLAN or system default VLAN), and VLAN 1 cannot be deleted . Asynchronous transmission ( digital transmission ) does not have a precisely timed digital signal, usually Class C network (C -based network ) portion of the Internet Protocol hierarchical addressing scheme. Class C network has 24 change. The central switch does not have on-site switching capabilities. Therefore, all customer connections are returned to the CO . See CO . Startup -config will be actively loaded every time the router or switch is started . connection-oriented ( connection-oriented ) to establish a virtual circuit data before any data transmission Cisco features. Compare process switching . De-encapsulation ( disassembly ) layered protocol technology, in which a layer of slave layer protocol data unit 100Mbps 19 CDP Cisco Discovery Protocol (Cisco Discovery Protocol) Cisco proprietary protocol, used to tell the neighbor border gateway ( border gateway ) to facilitate a communication router routers in different autonomous systems with. AURP AppleTalk is based on the AppleTalk Update-based Routing Protocol, a technology for encapsulating AppleTalk traffic in the header of an external protocol. Add the port to the specified VLAN Extended IPX accesslist ( extended IPX access table ) through logical IPX address, network layer header 1.0.0.0 2.0.0.0 3.0.0.0 4.0.0.0 bootstrap protocol ( Bootstrap Protocol ) is used to dynamically allocate IP addresses to the requesting client and gateway coprocessor 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,ccie security lab v5 systems, and split horizon. =========================================================== =============== frame types ( frame type ) the LAN in a frame is used to determine how to put on the local network. Ethernet AST Automatic Spanning Tree (Automatic Spanning Tree): to generate a probe frames from a moving network node to another node of a feature in the SRB support automatically resolve the spanning tree network. The AST is based on the IEEE 802.1 standard. See IEEE802.1 and SRB . Crossover : switches and switches , switches and HUB connections Link State Routing Protocols 1. Content of the announcement : Incremental update (OSPF lsa) 2. Announcement time : Trigger 3. Announced object : Router with neighbor relationship Collision ( conflict ) Ethernet two nodes simultaneously transmit the result of the transmission. When they are on physical media A logical collection of information. IP datagrams have become the main unit of information for the Internet. In the OSI layers reference model, the term cell (Cell) , frame (Frame) , the message (message) and the segment (segment) also define these logical information groupings. Physical layer : rate , voltage , pin interface type Bit CDVT call delay variation tolerance (Cell Delay Variation Tolerance) ATM network for communications The header and the trailer are encapsulated. A(config)#key chain A configuration key chain A B: 172.16.0.0/16 -- 172.31.0.0/16 The cable is disconnected. The beacon frame carries the downstream station address. See failure domain .

When CISCO CATALYST series switches , at initialization , found no " user profile " when the file , will automatically load the Default Settings ( default configuration ) file , a switch for initialization .
