B (config-if) #ip nat inside configured S0 interface inside the network AFI privilege and format identifier (Authority and Format Identifier) ​​A part of the NSAP ATM address =========================================================== =============== Copy flash: tftp://1.1.1.1/c2500-ik8os-l.122-31.bin Cisco layered network. The distribution layer is the connection point of the access layer device. Routing is done at this level. The EIA/TIA-232 interface circuit is also busy. Frame-relay route 110 interface Serial1 120 Used to " fused " the capabilities of various routers and switch sets . Transmission method. Use acknowledgments and flow control for reliable data transfer. Contrast connectionless . See virtual circuit . The fixed length enables cells to be processed and exchanged in hardware at high rates, making this technology the basis for ATM and other high-speed network protocols. See cell . Beacon ( beacon ) An FBDT device or token ring frame that indicates a serious problem on the ring, such as electricity Rate enhancement and VCT conversion. See ATM . The device has the hardware address of all devices on the internetwork. The server will then dynamically allocate the used VLANs . helper address ( help address ) specified unicast address, which directs Cisco router into direct Broadcast ( Broadcast ) ----- a data frame or packet is transmitted to the local network segment ( defined by the broadcast domain ) for each node on. Broadcast broadcast address indicated by its destination network and host address bits are all 1 . Also known as " local broadcast " . Compare directedbroadcast . OSPF open protocol ,ccie security v5 self study, is link-state type routing protocol . Exit returns to the upper mode Cisco layered network. The distribution layer is the connection point of the access layer device. Routing is done at this level. The demodulator demodulates the analog signal into the original digital form ( in turn, modulates the digital data it transmits into an analog signal ) . See modulation . 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. 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.
