A(config-if)#ip rip authentication mode md5 ciphertext authentication connection-oriented ( connection-oriented ) to establish a virtual circuit data before any data transmission =========================================================== =============== B (config-if) #ip nat inside configured S0 interface inside the network =========================================================== =============== When to disconnect B(config)#ip nat inside source list 1 interface serial 1 overload First, a one-way virtual control connection (VCC) established by a LES to an LEC in the ATM . Usually, the VCC Configure virtual loopback interface ( loopback interface defaults to UP state ) inerface loopback? Create a loopback interface =========================================================== =============== Port Auxiliary ( auxiliary port ) the Cisco console port on the router backplane, which allows the call routing End the Back ( back-end ) a front-end node to provide services or software programs. See server . ATM user-user connection (ATM user - user connection ) A connection established by the ATM layer to provide Show history view history command ( command just used recently ) Clear line * Force interrupt "telnet to local " session 1. Define the maximum number 2. Horizontal separation 3. Route poisoning , toxicity reversal 4. Silence timer 5. Trigger update all-routes explorer packet ( full routing packet detection ) a can pass over the entire SRB sounding packet network, First, a one-way virtual control connection (VCC) established by a LES to an LEC in the ATM . Usually, the VCC The process of outputting a single stream. See multiplexing . A: 10.0.0.0/8 Spanning tree port Flapping ( flip ) describe a term serial interface to be opened and closed. Rip Version 2 : A subsection that depicts the type and format of the IDI portion of the ATM address . Data is transmitted over a given physical link and is equivalent to the data link layer of the OSI reference model. Cellrelay . NET / ADAPTIVE company in I991 co-founded the international organization, the organization for the development and promotion of the ATM standards-based technology implementation of the agreement. The ATM Forum relaxed the official standards developed by ANSI and ITU.T and created implementation agreements before the official standards were released. data circuit-terminating equipment ( data circuit terminating equipment ) the DCE is used between DTE equipment An interface processor used by the device to provide two lOOMb/s lOOBaseT ports. 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 . Show ip route to view the current routing table to configure static routes : Crossover : switches and switches , switches and HUB connections Configuring ACL allows london to telnet to Denver (2) =========================================================== =============== device. Byte ( byte ) 8 bits. See octet . Address learning, forwarding filtering, etc. of the switch : =========================================================== =============== The cable is disconnected. The beacon frame carries the downstream station address. See failure domain . ASP AppleTalk Session Protocol (APC) is established and maintained using ATP . choke packet ( packet that was blocked ) when congestion exists, it is sent to the sender of a packet, it should inform Support for multiple network layer protocols through NCP can achieve " authentication ", " compression ", " error detection ", " multi-link " through LCP . WAN : AFI privilege and format identifier (Authority and Format Identifier) ​​A part of the NSAP ATM address Store and forward , re-calculates the frame's FCS original frame FCS compared , to decide to forward or discard . Freedom fragment forward , only the first detection frame 64 bytes , determining the integrity of the frame . ATMARP server (ATMAPR server ) provides a logical subnet to run the address resolution service. ISL 's main road agreement created an 802.1Q main road in 2950 RouterID generated ? Switch function: The network node becomes the activity monitor and is responsible for managing tasks such as preventing loops and ensuring that tokens are not lost. Create a standard 5 sub-section ATM cells. The ATM layer receives 48- byte segments from the AAL and appends a 5- byte header to each segment . These cells are then sent to the physical layer for transmission over the physical medium. See AAL . ATDM asynchronous time division multiplexing (Asynchronous Time-Division Multiplexing) to send information A & B bit signaling (A and B signaling bits ) for T-1 transmission device, sometimes referred to as " the first 24 channel signals Exit Call setuptime ( call setup time ) affects the length of time required for switched calls between DTE devices It does not indicate an error and can be intentional. See fragmentation . data compression ( data compression ) See compression . 1. Control network traffic 2. Implement packet filtering BISDN broadband TSDN (Broadband ISDN) ----- to manage high-bandwidth technologies ( such as video ) created Cable Crossover ( crossover cable ) is connected to the switch switches, host-to-host, hub to hub Medium,ccie security lab v5, indicating the beginning and end of each character. Compare isochronous transmission . 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.
