=========================================================== =============== between. It is also the time it takes for a packet to travel from its source through a path to its destination. See latency . Demarc ( demarcation ) The demarcation point between the Customer Premises Equipment (CPE) and the telephone company carrier equipment. Negotiation. 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 . Encapsulation frame-relay no shut Access-list 100 permit IP any any 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. 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 . ASP AppleTalk Session Protocol (APC) is established and maintained using ATP . change. The central switch does not have on-site switching capabilities. Therefore, all customer connections are returned to the CO . See CO . Telnet: Multi-person remote management ( depending on performance , number of VTY lines ). Not safe . Use the range of numbers assigned. The value of the cable range can be a sequence of one or several consecutive network numbers. Node addresses are determined by their cable range values. Grafing ( transplanted ) to activate a pruning process had been frozen interface process. It is sent to the router Link state type routing protocol: BISDN broadband TSDN (Broadband ISDN) ----- to manage high-bandwidth technologies ( such as video ) created =========================================================== =============== Ip route 4.0.0.0 255.0.0.0 2.0.0.2 The address is all ones . For hardware addressing, the hardware address will be all 1s in hexadecimal ( ie all F) . =========================================================== =============== ELAP EtherTalk Link Access Protocol (EtherTralk Link Access Protocol) on EtherTalk Network Switch function: Username 123 password cisco configuration user name password database , used to verify each other More details are configured. Allow multi-protocol support and interface configuration. Serial1 is down, Line protocol is down R14(config)#dialer-list 9 protocol ip list 1 Frame-relay map ip 10.1.1.2 110 broadcast for manual static mapping Dynamic NAT configuration 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. Modem and terminal. border router ( border router ) ----- generally Open Shortest Path First (OSPF) is defined as a region connected to the backbone routers region. But the border router can also be a router that connects a company to the Internet. See 0x2 Router will load the Flash in the IOS software . (Default config regcode) The node automatically performs the diagnosis and attempts to reconfigure the network by bypassing the failed area. 10.1.1.1/0.0.0.0 Vlan database enters vlan configuration mode vtp domain configures VTP domain name vtp password configures VTP password Coaxial cable classification for signaling. Compare baSeband . Switchport trunk encapsulation dot1q need to choose which way [dot1q|isl] switchport mode trunk change interface mode to trunk work mode show interface trunk view current switch TRUNK configuration Vlan database enters vlan configuration mode vtp domain configures VTP domain name vtp password configures VTP password Used to " fused " the capabilities of various routers and switch sets . Sending CDP packets every 60 seconds ( every 60 transmits second cdp packet ) HoldTime 180 seconds ( per CDP information is saved 180 [ seconds ) The convergence algorithm provides loop-free operation throughout the routing calculation. DUAL authorizes routers involved in topology versions that can be synchronized at the same time,building ccie security lab, and routers not involved are not affected by this change. See Enhanced IGRP . The CLI command line interface allows users to configure Cisco routers and switches with maximum flexibility . B(config-if)#ip nat outside configure S1 interface for the outside network to specify which hosts can NAT A: 10.0.0.0/8 =========================================================== =============== Programs ( such as email or file transfers ) to provide services. This layer selects and determines the validity of the communication object and the resources needed to establish the connection, coordinates the cooperating application, and forms a consistent process in controlling data integrity and error recovery.
