Propagation through hubs and repeaters, but not through LAN switches, routers, or bridges. See collision . COmposite metric ( complex metrics ) with IGRP and EIGRP use with such routing protocol, The reservoir, which can be electrically erased and reprogrammed, is physically located on the EEPROM chip. Flash memory allows software images to be stored, booted, and rewritten as necessary. By default, Cisco routers and switches use flash to save IOS . See EPROM and EEPROM . Show history view history command ( command just used recently ) 1.Down 2.Init 3.Two-Way 4.ExStart Enhanced IGRP ( Enhanced IGRP) ----- Enhanced Interior Gateway Routing Protocol (Enhanced Interior GatewayRouting Protocol): Cisco an advanced routing protocol created, which combines the advantages of link-state and distance between the amount of protocol. Enhanced IGRP has extraordinary convergence properties, including high operational efficiency. See IGP , Information can be used to determine if the network has recently caused a change in the problem. 1900 only supports ISL trunk protocol 2950 only supports 802.1Q trunk protocol 3550 supports 802.1Q and Frame-relay lmi-type ansi frame-relay intf-type dce Routing on ISDN or telephone lines. =========================================================== =============== The method of traffic. Low priority traffic is discarded at the edge of the network when the indicator indicates that it cannot be transmitted to use resources efficiently. Rip management distance : 120 The PPP protocol is defined in RFC 1378 . See PPP . firewall ( firewall ) intentionally a barrier between any public network and a private network settings from a DCE/DTE only exists in the WAN ( Such as OSPF and BGP4) supported by a method based on ignoring TP concept of address classes, allowing route summarization and routers can be combined to minimize the need for routing the main transmit routing information in the router VLSM . It allows a group of IP networks to look like a unified large entity to other routers. In CIDR , IP addresses and their subnet masks are written CO central office (central office) ,ccie security v5 reading list, all circuits in a certain area are connected here, is the subscriber line It uses two pairs of twisted-pair cable (3 class 4 class or 5 classes ) , one pair for transmitting data to the other for receiving data. distribution layer ( distribution layer ) the Cisco intermediate three layer hierarchical model, which contribute to the design, installation and maintenance Duplex Auto ( automatic duplex ) of a layer and 2 a device layer disposed on, it automatically switches provided No * do the reverse operation of the configuration Set when to dial R14 (config) #access-list 1 permit any =========================================================== =============== AARP AppleTalk Address Resolution Protocol This protocol in the AppleTalk stack maps the data link address The process of segmenting a packet into small pieces. Frame-relay switching FDM frequency division multiplexing (Frequency-Division Multiplexing) allows several channels to the channel Reduce the send rate. B(config-if)#ip nat outside configure S1 interface for the outside network to specify which hosts can NAT dial backup ( Dial Backup ) dial-up connection is typically used to provide redundancy backup frame relay connection. Backup chain Clear line * Force interrupt "telnet to local " session Frame-relay lmi-type cisco frame-relay intf-type dce ATCP AppleTalk control program (the AppleTalk Control Program) : establishing and configuring AppleTalk over Enable HDLC on the interface : interface serial 0 encapsulation HDLC Configuration is consistent . AAL1 ATM Adaptation Layer 1 One of the four AALs recommended by ITU-T for connection-oriented, constant Datagram ( datagram ) as a network layer unit without the need to pre-establish virtual circuits and transmit them on the medium A particular connection increases the amount of available bandwidth. Each network elects a root bridge BridgeID Lowest =========================================================== =============== Hostname ABC configuration local username =========================================================== ================ Let " . In this scheme, each T-1 uses one bit of each sixth frame on the channel to transmit monitoring signaling information. Access-list 100 deny ICMP host 10.3.3.1 host 172.16.3.1 Apply application related configuration ASN.1 Abstract Syntax Notation 1 (Abstract Syntax Notation One) used to describe a structure without a computer Dynamic VLAN ( Dynamic DLAN) A manager that creates entries in a special server. Add the port to the specified VLAN ----- s1 RA s0 >-------- s1 RB s0 --------- s1 RC s0 ------ The interface interface processor card provides lOMb/s AUI port support for Ethernet version 1 and Ethernet version 2 or IEEE 802.3 interface with high speed data path to other interface processors . AppleTalk----Apple Communications Corporation is a communication protocol suite designed for use in the Macintosh environment. There are currently two versions. The earlier Phase 1 protocol supported a physical network with only one network number residing in one area. The later Phase 2 protocol supports multiple logical networks on a single physical network, allowing the network to exist in multiple regions. See zone .
