Enable password Broadcasting is not supported by FRAME-RELAY , which will cause the route to be unadvertised . Solution : Copy multiple frames for announcement. =========================================================== =============== The root port does not participate in the competition of the specified port. 2) Usually all the interfaces of the root bridge are designated ports. FTP file transfer protocol (File Transfer Protocol): used to transfer files between network nodes of TCP / IP =========================================================== =============== The signal has been established. Show sessions show the current outgoing TELNET session Bypass mode ( bypass mode ) removes FDDI and Token Ring network operations for an interface . helper address ( help address ) specified unicast address, which directs Cisco router into direct Crossover : switches and switches , switches and HUB connections 10.1.1.1/255.255.255.255 Using private IP addresses host , you can not directly access the public network (Internet) private IP public network router will not appear in the routing table . Part of the computer sends data to another part. Access-list 100 deny ICMP host 10.3.3.1 host 172.16.3.1 DVMRP distance between the amount of multicast routing protocol (Distance Vector Multicast Routing Protocol) is mainly based on Routing Information Protocol (the RTP) , the Internet gateway protocol a common, strong 1.A vlan == A broadcast domain == A logic subnet E.164 1) evolved from the standard telephone numbering system, which is numbered by ITU-T , especially at The route to the network. Rip Version 2 : IGRP: based on bandwidth,ccie security v5 study material, latency, reliability, load, MTU (maximum transmission unit) Frame Relay bridging ( FR bridge ) in 1490 RFC definition, uses this bridging method Create a VLAN the alignmentError ( alignment error ) Ethernet The error occurring in the network, the received frame in which the additional The MAC address filter table determines which port is the destination hardware address to which the received hardware address is destined. The frame will only be allowed to pass through that segment. If the hardware address is unknown, the frame is forwarded to all ports. bootstrap protocol ( Bootstrap Protocol ) is used to dynamically allocate IP addresses to the requesting client and gateway coprocessor List Access ( access list ) to save the router a set of test conditions, which determine the various services on the network " interested Extended IPX accesslist ( extended IPX access table ) through logical IPX address, network layer header bridge priority ( bridge priority ) disposed bridge STP priority. By default all bridges take precedence An international standard for transmitting cells in a variety of business systems, such as voice, video or data. The reduction in transmission delay is due to the fact that fixed length cells are allowed to be processed in hardware. ATM is designed to enable high-speed transmission media ( such as SONET , bit-oriented protocol ( bit oriented protocol ) regardless of the content of the frame, the data link layer communication protocol such A digital device of the loop. Often referred to as a CSU/DSU along with a data service unit . See DSU . Static NAT configuration Layer and Transport layer . Whether a given node ID in an AppleTalk network is used by another node. If the node ID is used at the end, the sending node can use the ID of that node . If the node ID is already used, the sending node will select a different ID and send more AARP probe packets. See AARP congestion avoidance ( congestion avoidance ) to minimize latency, the ATM network for controlling the system into Copy tftp: startup-config copy flash: tftp: Show sessions show the current outgoing TELNET session (Amplitude magnitude ) the maximum analog or digital waveform. Static NAT configuration RouterID generated ? ATM ATM (Asynchronous Transfer Mode) by a fixed-length 53 -byte element identifier Class C network (C -based network ) portion of the Internet Protocol hierarchical addressing scheme. Class C network has 24 100BaseTX is based on the IEEE 802.3U standard, 100BaseTX is wired using two pairs of UTP or STP Debug ip eigrp notifications debug event notification Duplex Half ( half duplex ) can only capability between the side transmitting data between a transmitting and receiving stations. See fullduplex . BGP Identifier (BGP Identifier ) that identifies the segment comprises Yu BGP a value of the speakers. This is by Ip address 1.1.1.1 255.0.0.0 Configure the IP address of the interface Startup -config will be actively loaded every time the router or switch is started . Communication between two ATM service users ( such as ATMM processes ) . These communications can be one-way or two-way, using one or two VCCs , respectively . See ATM layer and ATMM . ACL is the most important : The ACL condition list will have a condition of hiding " reject all " at the end . 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 . IGRP is a CISCO private routing protocol that can only be implemented and deployed on CISCO routers . IOS Cisco Cisco Internetwork Operating System Software (Cisco Internetwork Operating System software) ----- as CiscoFusion provide the functionality shared by all products in the off-line configuration, scalability and security of Cisco core routers and switches series. See CiscoFusion . Configure a static default route to indicate which interface to send to the unknown network , which interface to send the packet R14 (config) #ip route 0.0.0.0 0.0.0.0 bri 0 Datagram ( datagram ) as a network layer unit without the need to pre-establish virtual circuits and transmit them on the medium Link State Routing Protocols device. Byte ( byte ) 8 bits. See octet . The BPDU is exchanged between switches every two seconds. Periodic. Duplex Auto ( automatic duplex ) of a layer and 2 a device layer disposed on, it automatically switches provided 4. Ways of notification : Unicast & Multicast Baud ( baud ) ----- bits per second (b / s) synonymous, if each cell represents one bit of the signal words. It is a unit of signaling speed equivalent to the number of individual signal units transmitted per second. The credibility value of the source. The smaller the value, the higher the level of constitutionality 1. Port-based implementation , static VLAN 2. Based on MAC address implementation , dynamic VLAN TRUNK ( trunk ): uses a special encapsulation mechanism to transfer data from multiple VLANs . 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.
