Ethernet cable type for switch or switch to hub. Interface s 1.??? point-to-point enables a peer -to- peer subinterface . ??? is the interface number . ip add 10.1.1.1 255.255.255.0 configures the ip for the subinterface Configuring VTP Frame ( frame ) logical unit of information transmitted on the transmission medium by the data link layer. The term is often involved BPDU: Bridge Protocol Data Unit Bridge Protocol Data Unit data compression ( data compression ) See compression . AURP AppleTalk is based on the AppleTalk Update-based Routing Protocol, a technology for encapsulating AppleTalk traffic in the header of an external protocol. Configure terminal enters global configuration mode NetMask: target network subnet mask EEPROM electrically erasable programmable read-only memory is programmed after shipment. These non-volatile memory chips can be used when needed. Source : 10.3.3.1 It can be provided by a secondary router added to a remote network. =========================================================== =============== Configuring ACL allows london to telnet to Denver (2) Encapsulation frame-relay The CISCO 1900 series switches use free shard forwarding to forward this forwarding method by default. 1. Reduce the size of the routing table 2. Speed ​​up the convergence 3. Limit the spread of LSA 4. Improve stability Interface Serial1 no ip address Autoreconfiguration ( automatic reconfiguration ) token ring domain failure of a process performed by the node, The traffic " rounds and goes to the router. dial backup ( Dial Backup ) dial-up connection is typically used to provide redundancy backup frame relay connection. Backup chain CBR constant bit rate ----- ATM forum created for use in ATM networks 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,ccie security lab v50, and link can also be used . Binding ( binding ) in LAN configuration on a network layer protocol to use some type of frame Class B network (B -based network ) portion of the Internet Protocol hierarchical addressing scheme. Class B network has 16 B (config-if) #ip nat inside configured S0 interface inside the network VTP message announcement , only possible TRUNK transmission on . 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 And make console configuration settings. Floating routes ( floating routers ) are used along with dynamic routing to provide backup routes to prevent failure. UDP ( User Message Protocol ), no connection , no retransmission mechanism , unreliable transmission The main path of traffic. Connector type : BNC interface , AUI interface , RJ45 interface , SC/ST interface Access-list 100 permit IP any any Flash ( flash )----- Electrically erasable programmable read only memory (EEPROM) . Used by default to save CiscoIOS on the router . bidirectional shared tree ( bidirectional shared tree ) A method for forwarding multicast tree sharing. This method allows ++<6> + x Configure a password for the console port : Control direct VCC . (Amplitude magnitude ) the maximum analog or digital waveform. 0x2 Router will load the Flash in the IOS software . (Default config regcode) FDM frequency division multiplexing (Frequency-Division Multiplexing) allows several channels to the channel Username 123 password cisco configuration user name password database , used to verify each other 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. Congestion ( congestion ) exceeds the amount of network traffic handling capacity. Experiment : AIP ATM Interface Processor (ATM Interface Processor) ----- supports AAL3 / 4 and AAL5. Cisco For broadcast frames and multicast data frames , the switch forwards flooding by default. The other party is not configured with the same Layer 2 protocol serial interface default encapsulation: HDLC dynamic entries ( dynamic entries ) for the first 2 layer and 3 to create a hardware device address dynamically layer DNS is associated. See DNS . More details are configured. Allow multi-protocol support and interface configuration. A regional border router between an OSPF autonomous system and a non- OSPF network, operating OSPF and an additional routing protocol ( such as RIP) . The ASBR must be in a non-stub OSPF area. See ABR , non-stub area, and OSPF . ASN.1 Abstract Syntax Notation 1 (Abstract Syntax Notation One) used to describe a structure without a computer Ip route 4.0.0.0 255.0.0.0 2.0.0.2 The distance limit of each segment of 1OBaseT is about 100 meters. See Ethernet and IEEE 802.3 . =========================================================== =============== 5.ExChange 6.Loading 7.Full 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 . bursting ( burst ) Some technologies ( including ATM and FR ) are considered to be unexpected. This means the user boot sequence ( leader sequence ) define how routers boot. The configuration register tells the router where to go from Router, which is required for other special tasks in OSPF operations. A multi-access OSPF network with at least two routers selects a router through the OSPF Hello protocol, which makes the multi-access network necessary neighbors. =========================================================== =============== Autonomous switching (autonomous switching Cisco routers use ciscoBus to independently exchange system processing Show cdp neighbors detail View CDP neighbors ( including Layer 3 IP addresses ) show cdp entry * View CDP neighbors ( including Layer 3 IP addresses ) 4. Ways of notification : Unicast & Multicast Each non-root bridge elects a root port 1) Bandwidth Cost Lowest 2) Recevied BridgeID Lowest 1. Full mesh 2. Half mesh 3. Star and spoke Corelayer The top layer of the Cisco three-tier hierarchical model that helps design, build, and maintain a Programs ( such as email or file transfers ) to provide services. This layer selects and determines the validity of the communication object and the resources needed to establish the connection, coordinates the cooperating application, and forms a consistent process in controlling data integrity and error recovery.
