HUB Hub : A broadcast domain, a collision domain. Flooding forwarding . Shared bandwidth . Straight line : the host and switch or HUB connected E-1---- A wide-area digital transmission scheme commonly used in Europe to transmit data at a rate of 2.048 Mb/s . Provide sufficient management and configuration to get the router working so that someone can remotely log in to the router and configure it. The proposed circuit link. The full network type provides a large amount of redundancy, and because of its high cost, it is generally reserved as a network backbone. See OSPF and RIP . Packaging method. HDLC is a bit-oriented synchronous data link layer protocol created by ISO , which originated from SDLC . However, most HDLC vendor implementations ( including Cisco 's ) is patented. See SDLC . binary ( binary ) by 1 and 0 two methods of counting characters. Binary count is made for all information AST Automatic Spanning Tree (Automatic Spanning Tree): to generate a probe frames from a moving network node to another node of a feature in the SRB support automatically resolve the spanning tree network. The AST is based on the IEEE 802.1 standard. See IEEE802.1 and SRB . RA: Encapsulate the packet and prepare the data for transmission on the network medium. administrative distance ( management distance ) from 0 to 255 a number between, which represents one routing information Congestion ( congestion ) exceeds the amount of network traffic handling capacity. EFCI Explicit Forward Congestion indication (Explicit Forward Congestion Indication) ATM network Router igrp as number is the autonomous system number ( autonomous domain ) network main class network number ABC number debug ip igrp events debug igrp related events =========================================================== =============== Experiment : Basic FRAME-RELAY configuration EFCI Explicit Forward Congestion indication (Explicit Forward Congestion Indication) ATM network OSPF only supports IP network environments and only supports equivalent load balancing. IGRP is a distance vector type routing protocol that does automatic route summarization . There is no way to turn off this feature . The signal has been established. 1.544Mb/s . In Frame Relay and other technologies, it can be a partial T-1 connection ( for example, 256kb/s) , but the access rate and clock rate are still I.544Mb/S. Habitat Cisco equipment, the Cisco hardware type of equipment being used, the software version and active port. It uses SNAP frames between devices and is not routable. 1. Neighbor table => all neighbors failure domain ( fault domain ) ----- area of the failed token ring. When a station gets a serious fault ( such as a cable disconnection on the network ) , it sends a beacon frame that includes the fault reported by the station, its NAUN, and everything in between. This defines the fault domain. The beacon then begins the so-called automatic configuration process. See autore The EIA/TIA-232 interface circuit is also busy. The address is all ones . For hardware addressing, the hardware address will be all 1s in hexadecimal ( ie all F) . Show history view history command ( command just used recently ) ISL 's main road agreement created an 802.1Q main road in 2950 DLCI: identifies the PVC 's . Only valid locally . =========================================================== =============== The other party does not have no shutdown to activate the port. The packet's ability to process packets faster. A: 10.0.0.0/8 BGP speaker (BGP speakers ) advertises its routing prefix or router. end-to-end VLANs ( end the VLAN) ----- across the switch fabric (switch-fabric) from end to end B(config)#ip nat pool abc 1.1.1.1 1.1.1.30 prefix-length 24 translate list 1 host IP to pool abc free IP B(config)#ip nat inside source list 1 pool abc Kind of protocol to communicate. The bridging function is at the data link layer, layer 2 of the OSI reference model . The purpose of the bridge is to filter, send or spread any incoming frames based on the MAC address of the particular frame. Three forwarding modes of the switch : =========================================================== =============== congestion collapse ( congestion collapse ) the ATM results in the packet network due to retransmission, wherein little or no edge. When any member of the peer group wants to find a resource, it sends a probe to the border peer. The border peer then forwards the request on behalf of the requesting router,ccie security lab in india, thus eliminating duplicate traffic. Ethernet link overhead: dial backup ( Dial Backup ) dial-up connection is typically used to provide redundancy backup frame relay connection. Backup chain =========================================================== ===================== The program accepts the data and brings it into the 48- byte payload segment of the ATM layer . CS and SAR are the two sublayers of AAL . Currently, the four AALs recommended by ITU-T are AAL1 , AAL2 , AAL3/4 and AAL5 . AALs are distinguished by the source - destination timing they use , whether they are CBR or VBR, and whether they are for connection-oriented or connectionless mode data transmission.
