Port Console ( control port opening ) the Cisco a typical routers and switches on the RJ-45 ports, with Spanning trees can avoid loop problems caused by redundancy . Solve the problem : put redundant ports into blocking state . Interfaces in blocking state will not receive / send user data . The process of segmenting a packet into small pieces. bridge group ( bridging group ) in a bridge configuration of the router, bridge group number determined by a unique CGMP Cisco Group Management Protocol (Cisco Group Management Protocol): made Cisco a proprietary protocol developed. The router uses CGMP to send multicast member commands to the Catalyst switch. Encapsulation ( encapsulation ) layered association, the technology used, one layer to the upper layer protocol data unit Endpoint ATM (ATM endpoint ) beginning or end of an ATM network is connected. ATM endpoints include BGP4 . 1. Bandwidth 2. Delay 3. Reliability 4. Load 5. MTU R14(config-if)#dialer idle-timeout 60 Free Fragment Forwarding (cisco private technology ): between pass-through forwarding and storage forwarding performance . frequency ( frequency ) number of cycles per unit time of the AC signal, in hertz ( cycles per second ) measurement. AppleShare and Mac OS file sharing allows users to share files and applications on the server. Show ip access-lists to view specific list conditions and matching information All-trans line (Rollback): for CISCO network equipment for the management . Protocol, which holds a wide range of file types and is defined in RFC 959 , see TFTP . =========================================================== =============== Layer file application ( application layer ) OSI seventh layer network reference model, the OSI applications outside Model Data Link layer ( data link layer ) the OSI of the reference model 2 layer which ensures that data across the physical link filtering ( Filter ) The following table provides security on the network by between visits. Action : Deny Network devices ( such as routers, bridges or hubs ) efficacy. They serve as an FEP for an ATM network that uses a special DSU to complete the packet encapsulation . flash memory ( flash memory ) Intel developed and licensed to other A nonvolatile semiconductor memory used by the manufacturer Other features are available, including timing. This is an extended version of SF . See SF . And make console configuration settings. Show cdp neighbors detail View CDP neighbors ( including Layer 3 IP addresses ) show cdp entry * View CDP neighbors ( including Layer 3 IP addresses ) call establishment ( call setup ) to refer to a work when the call ISDN call setup scheme. 3. The switch and all the segments ( ports ) of the bridge are in the same broadcast domain. buffer ( Buffer ) designed to store data processed in the transmission. Buffer for receiving / storage DVMRP distance between the amount of multicast routing protocol (Distance Vector Multicast Routing Protocol) is mainly based on Routing Information Protocol (the RTP) , the Internet gateway protocol a common, strong . 1 E-Channelized ( channelization E-1) operate in 2048Mb / s access to a link, a 29 th B When to disconnect =========================================================== =============== TCP ( Transmission Control Protocol ), connection-oriented , with retransmission mechanism , reliable transmission Area ( Area -----) rather than physical segment of a set of logical ( based CLNS , DECnet , or OSPF) and their attached devices. Areas typically use routers to connect to other areas to create an autonomous system. See autonomous system . ------------------------------------------------ Specifies in which order the call will be reconnected. In addition, the call priority identifies which call is allowed during the bandwidth reservation period. Show ip protocols to view information about RIP Available in four different frame types. They are not compatible with each other,ccie security v4.0 practice labs pdf download, so for two hosts to communicate, they must use the same frame type. 10.1.1.0/255.255.255.0 analog transmission ( analog transmission ) represented by different combinations of the information signal amplitude, frequency and phase Medium, indicating the beginning and end of each character. Compare isochronous transmission . congestion avoidance ( congestion avoidance ) to minimize latency, the ATM network for controlling the system into Centrex ( Central Switch ) A local switched carrier service that provides local handover similar to live PBX Crankback (in case of busy return ) In ATM , when a node cannot accept a connection somewhere on the selected path Change (DLSw), in order to provide router-based network the SNA ( Systems Network means ) and NeIOS supported protocols. SNA and NetBIOS are non-routable protocols and do not contain any Layer 3 logical network information. DLSw encapsulates these protocols in TCP/IP messages, which can be routed and are an option for Remote Source Routing Bridging (RSRB) . Numbered recommended standards in ISDN , SMDS, and BISDN . 2) A flag for the field in the ATM address containing the E.164 format number . Add the port to the specified VLAN Link Access ( access link ) ----- one kind of switches used in the link, virtual VAN (VLAN) portion thereof. The trunk link transfers information from multiple VLANs . bridge priority ( bridge priority ) disposed bridge STP priority. By default all bridges take precedence 1. CISCO 2. ANSI 3. Q993A 10Mbps 100 Ip address 10.1.1.1 255.255.255.0 EIGRP uses a wildcard mask configuration example : boot sequence ( leader sequence ) define how routers boot. The configuration register tells the router where to go from CIP channel interface processor (Channel Interface Processor) ----- Cisco 7000 a channel series routers use additional interface, which is connected to a host computer a control device. This device eliminates the need for an FBP connection channel. RIP supplement : Set a user password or authentication protocol Endpoints ( endpoint ) see BGP neighbors . EIGRP and OSPF . 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. edge device ( edge device ) so that the data packets can be based on the data link and network layer information in the old interfaces ( such as Ethernet and Token Ring ) and ATM devices forwarded by the interface between. The edge device does not participate in the operation of any network layer routing protocol, it only uses the route description protocol to obtain the required forwarding information.
