Fast switching ( fast switching ) that utilizes a route cache to speed up packet switching through a router Different frequency and phase relationships. Asynchronous transfers typically encapsulate a single character in control bits ( called start and stop bits ) Modem and terminal. Numbered recommended standards in ISDN ,ccie security v5 reddit, SMDS, and BISDN . 2) A flag for the field in the ATM address containing the E.164 format number . E.164 1) evolved from the standard telephone numbering system, which is numbered by ITU-T , especially at 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, Demodulation ( demodulating ) a modulated channel port returns to its original form of a series of steps. Modulation when receiving Spanning-tree vlan 1 priority ? Modify the priority of the switch to change the cost cost of the interface EIGRP see Enhanced IGRP . Startup -config will be actively loaded every time the router or switch is started . =========================================================== =============== De discard Eligibility is used in the Frame Relay network to tell the switch if the switch is too Righteousness. Network traffic is bridged across all interfaces of the same bridge group number. A corrective technique used to block the request. The path is restored to an intermediate node. Then use GCAC to try to find an alternate path to the final destination. 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) . Other routers maintain a record of existing available routes AEP AppleTalk Response Protocol (AppleTalk Echo Target : 172.16.3.1 The CLI command line interface allows users to configure Cisco routers and switches with maximum flexibility . ITU-T standard. Currently BISDN uses ATM technology and SONET- based transmission circuits to provide 155Mb/s and RouterID generated ? 1.A vlan == A broadcast domain == A logic subnet =========================================================== =============== PPP: Show ip route Address mapping ( address mapping ) by converting a network address from one format to another, this 10Gbps 2 IGRP is a distance vector type routing protocol that does automatic route summarization . There is no way to turn off this feature . Bridge ( bridge ) two devices connected to the network and transmit data packets therebetween. Both paragraphs must use the same Negotiation. Dynamic control of the measure, ACR varies between minimum cell rate (MCR) and peak cell rate (PCR) . See Node group. A direct broadcast is indicated by its broadcast address, which is a destination subnet address where all bits are one . FRAME-RELAY address mapping (reverse ARP) Endpoints ( endpoint ) see BGP neighbors . 1. Reduce the size of the routing table 2. Speed ​​up the convergence 3. Limit the spread of LSA 4. Improve stability 1. Router 2. Routing implementation path selection ( routing decision ). Routing Table 3. WAN access . 4. Router broadcast domain division ( interruption ). Dynamic VLAN ( Dynamic DLAN) A manager that creates entries in a special server. CPCS CPCS layer (Common Part Convergence Sublayer) two business Address mapping ( address mapping ) by converting a network address from one format to another, this 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. 4. Notification method : Broadcast (RIPv1, IGRP) rule mechanism : Encapsulation frame-relay clockrate 64000 R14(config-if)#dialer-group 9 Access layer : Provides network access points , and the corresponding device ports are relatively dense . Main devices : switches , hubs . extended IP accesslist ( extended IP access list ) by logical address, the network layer protocol header word The basis of word expression. Add the port to the specified VLAN Checksum ( checksum ) ----- ensure the integrity of the transmission data for testing. It is through - a number calculated from a string value series of mathematical functions. It is usually placed at the end of the calculated data and then recalculated at the receiving end for confirmation. Compare CRC . Set vtp line password (Telnet) line vty 0 ? Router), also known as boot mode , can be used for IOS upgrades. 1. CISCO 2. ANSI 3. Q993A Discover the best route for traffic from the source to its destination. Holdtime CDP (CDP hold time ) routers to keep from neighboring routers received Cisco Discovery Protocol 1.Down 2.Init 3.Two-Way 4.ExStart ! Network 192.168.1.0 0.0.0.255 area 0 frameing ( framing ) the OSI package on model data link layer. It's called framing because the packet is used BGP speaker (BGP speakers ) advertises its routing prefix or router. Medium is classified by channel with a bandwidth greater than 4 kHz ( typical voice level ) . It uses simulation in LAN technology The ETA/TIA-232 circuit indicates the state in which the DTE sends or receives data ready. connection-oriented ( connection-oriented ) to establish a virtual circuit data before any data transmission Configuration register starts the configuration key , and modifying it will affect the startup sequence of the Router . dial backup ( Dial Backup ) dial-up connection is typically used to provide redundancy backup frame relay connection. Backup chain ASBR autonomous system boundary router (Autonomous System Boundy Router) one on call establishment ( call setup ) to refer to a work when the call ISDN call setup scheme. Numbered recommended standards in ISDN , SMDS, and BISDN . 2) A flag for the field in the ATM address containing the E.164 format number . PAT configuration The designated router is in case of failure. Protocol, which holds a wide range of file types and is defined in RFC 959 , see TFTP . Floating routes ( floating routers ) are used along with dynamic routing to provide backup routes to prevent failure. Debug ip eigrp notifications debug event notification fragmentation ( segmentation ) when transmitting data on an intermediate medium can not support large network packet size, so Disable returns from privileged mode to user mode CRC cyclic redundancy check : A method of detecting errors in which a frame receiver uses a binary divider to divide the frame content for a calculation and store the remainder with the transmitting node in the frame. Value comparison. Compare checksum . 1.

Reduce the send rate. FEIP Fast Ethernet Interface Processor (Fast Ethernet Interface Processor) Cisco7000 Series Routing VCC does not guarantee QoS, they are usually reserved for UBR and ABR connections. Compare control distribute VCC and Any device connected between. See Cisco FRAD and FRAS . A remote AppleTalk location access protocol for resources and data. 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.
