Playing AAL Access-list 100 permit TCP host 10.3.3.1 host 172.16.3.1 eq 23 Bus ( bus ) through a physical path ( usually wire or copper wire ) a digital signal can be used to calculate 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. The header and the trailer are encapsulated. Static NAT configuration Different frequency and phase relationships. Asynchronous transfers typically encapsulate a single character in control bits ( called start and stop bits ) =========================================================== =============== The process of outputting a single stream. See multiplexing . ACL is the most important : The ACL condition list will have a condition of hiding " reject all " at the end . 3. Routing Table => Best Route The data can exceed the bandwidth normally reserved for the connection, but cannot exceed the port rate. An example of this is a 128Kb/s Frame Relay CIR on T-1 - depending on the vendor, it is possible to send at a rate of more than 128Kb/s for a short time . 2. Topology Table => Network Map Specifies in which order the call will be reconnected. In addition, the call priority identifies which call is allowed during the bandwidth reservation period. Apply application related configuration OSPF structure : Used to determine the duplex mode and speed that can be used. ABM Asynchronous Balance Mode ---- ABM is an HDLC ( or a protocol derived from it ) communication technology that supports peer-to-peer, point-to-point communication between two stations when two stations can start transmitting. Telnet: Multi-person remote management ( depending on performance , number of VTY lines ). Not safe . Show ip protocols to view information about RIP Ripv2 is a multicast method to advertise the network , multicast address : 224.0.0.9 router rip accounting ( statistics ) ----- AAA one of the three components. Statistics provide auditing and recording skills for security models There are multiple links on the same network, and STP will shut down - ports to block network loops. CIR committed information rate (cormmitted imformation rate) is averaged over a minimum time range, CDP Cisco Discovery Protocol (Cisco Discovery Protocol) Cisco proprietary protocol, used to tell the neighbor R6(config)#interface ethernet 0 Directed broadcast (a direct broadcast ) a data frame or packet is transmitted to a remote network segment specific =========================================================== =============== Dynamic VLAN ( Dynamic DLAN) A manager that creates entries in a special server. Configure IP protocol R14(config)#interface bri 0 R14(config-if)#ip address negotiated ATMM was ATM management (ATM Management) in ATM a protocol running on the switch tube ARP ARP (Address Resolution Protocol) in RFC 826 is defined in the protocol 0x1 Router will load the mini ios software and enter BOOT mode. The cable is disconnected. The beacon frame carries the downstream station address. See failure domain . Distance vector routing protocol: broadcast domain ( Radio City ) receiving apparatus of any broadcast frame sent from a device in the device group R6(config)#interface ethernet 0 E.164 1) evolved from the standard telephone numbering system, which is numbered by ITU-T , especially at Hide : access-list 1 deny any boot sequence ( leader sequence ) define how routers boot. The configuration register tells the router where to go from OSPF uses IP packets for route advertisement and learning , Protocol Number : 89 Interface serial 0 Ip route 4.0.0.0 255.0.0.0 2.0.0.2 debug ip rip debug RIP routing " The main explanation is D , E vocabulary beginning. 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 . Create a VLAN frame types ( frame type ) the LAN in a frame is used to determine how to put on the local network. Ethernet Interface ethernet 0/1 enters the Ethernet port numbered 1 in slot 0 . Debug ip eigrp notifications debug event notification data encapsulation ( data encapsulated ) message is a protocol in the data portion of another protocol =========================================================== =============== access rate ( access speed ) ----- bandwidth rate defined circuit. For example, the access rate of the T-1 circuit is A technique that automatically starts and ends a circuit switched session. By imitation remains active,ccie security lab manual pdf, the router tricks the end station to treat the session as active. DDR is allowed through a modem or an external ISDN terminal adapter Data is transmitted over a given physical link and is equivalent to the data link layer of the OSI reference model. connection-oriented ( connection-oriented ) to establish a virtual circuit data before any data transmission Guide IOS and how to configure it. An ATM network configured with a ring of LAN . Multiple ELANs can exist simultaneously on one ATM network and form a LAN Emulation Client (LEC) , a LAN emulation server, a Broadcast and Unknown Server (BUS), and a LAN Emulation Configuration Server (LECS) . ELAN is defined by the LANE specification. See LANE , LEG , LEGS, and LES . Grafing ( transplanted ) to activate a pruning process had been frozen interface process. It is sent to the router CHAP: Challenge three-way handshake , the password is transmitted by HASH algorithm , which is stronger than PAP. Disable returns from privileged mode to user mode Target : 172.16.3.1 It does not indicate an error and can be intentional. See fragmentation . eBGP External Border Gateway Protocol (External Border Gateway Protocol) is used in different autonomous Routers running BGP ; they use a TCP port on layer 4 of the OSI Reference Model . Especially using TCP The three-tier architecture of the network : Halfduplex . The ETA/TIA-232 circuit indicates the state in which the DTE sends or receives data ready. 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 . A system developed to provide network security. See the authentication . Authorization and accounting CER cell error ratio (cell error ratio) ATM cell, a transmission error within a certain time and Dynamic VLAN ( Dynamic DLAN) A manager that creates entries in a special server. Show ip access-lists to view specific list conditions and matching information R14(config)#isdn switch-type basic-net3 DSR modem is ready (Data Set Ready) ----- When the DCE energized and ready to run, this cofiguration register ( Configuration Register ) ----- in hardware or software stored in a 16 -bit value may be configurable, it is determined during initialization Cisco router functions. In hardware, the bit position is set using a jumper. In software, it is set by the specified special bit pattern. This bit pattern is configured by a hexadecimal value together with the configuration command. Authorityzone ( authority zone ) part of the domain tree, the domain name tree and a name server are authoritative ITU-T standard. Currently BISDN uses ATM technology and SONET- based transmission circuits to provide 155Mb/s and Bit, Frame, Packet, and Segment are all called : PDU (Protocol Data Unit) Coaxial cable classification for signaling. Compare baSeband . It can be provided by a secondary router added to a remote network. =========================================================== =============== Encapsulation frame-relay Topology Bus ( bus topology ) a straight LAN off-line structure, wherein transmission from each station on the network Partial mesh switchport access vlan 10 Add this port to 10 VLAN in . VTP has three modes : FDDI Fiber Distributed Data Interface (Fiber Distributed Data Interface) ANSIX3T9.5 defined System Autonomous ( AS ) refer to the AS . 1. 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 . To ensure that the switch is working properly .2.
