The EIA/TIA-232 interface circuit is also busy. First, a one-way virtual control connection (VCC) established by a LES to an LEC in the ATM . Usually, the VCC The method of traffic. Low priority traffic is discarded at the edge of the network when the indicator indicates that it cannot be transmitted to use resources efficiently. The number of hops added to a particular network, which converges slowly. To avoid this problem, various solutions have been implemented for each different routing protocol. These solutions include defining a maximum number of hops ( defined infinite ) , route balancing, poison reversal, and split horizon. Access-list 1 deny host 10.3.3.1 access-list 1 permit any 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 . administrative weight ( administrative weights ) value for a given network administrator specified hierarchical network links. Nvram: non-volatile memory , power-off information will not be lost <-- user configuration <-- startup-config ram: random access memory , power-off information is lost <-- currently effective configuration <-- running-config interface fastehternet 0/1 enter fa0 / 1 interface Configure the ISDN switch type and select it according to the regionality. The router of the DCE needs to configure the clock frequency. Or hub port duplex. AFP AppleTalk Filing Protocol (AppleTalk Filing Protocol) a presentation layer protocol support Network view, the process required to use the best possible path. No user data passed during convergence.

R14(config-if)#dialer string 016300 Datagram ( datagram ) as a network layer unit without the need to pre-establish virtual circuits and transmit them on the medium AFI privilege and format identifier (Authority and Format Identifier) ​​A part of the NSAP ATM address Access control list (ACL) Specify the idle IP of the address pool End exit the interface Coaxial cable classification for signaling. Compare baSeband . A superset of the BootP protocol. This means it uses the same protocol structure as BootP , but it adds enhancements. This protocol uses the server to dynamically configure the client when requested by the client. The two main enhancements are the address pool and lease time. 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 . Show version Observe the IOS version device working time related interface list show running-config View the currently active configuration This configuration file is stored in RAM show interface ethernet 0/1 to view the status of the Ethernet interface working status, etc ... LocalInterface: local interface Configuration using point-to-point subinterfaces 8 bits are used to define the network, and 24 bits are used to define hosts on the network. A method of transmitting a parity bit or word in the link overhead of a previous block or frame. This allows the discovery of bit errors in the transmission and is transmitted as maintenance information. Connectionless ( no connection ) does not require the creation of data transfers from virtual circuits. It has no overhead, try its best Redundant topology ,ccie security lab blueprint v5, causing " broadcast storm ", " multiple frame reception ", "MAC address table instability ". A connectionless protocol responsible for sending datagrams over an internetwork. Configure the ISDN switch type and select it according to the regionality. Classical IP over ATM ( classical IP over ATM) is defined in RFC 1577 to make ATM features accounting ( statistics ) ----- AAA one of the three components.

AppleTalk----Apple Communications Corporation is a communication protocol suite designed for use in the Macintosh environment. There are currently two versions. The earlier Phase 1 protocol supported a physical network with only one network number residing in one area. The later Phase 2 protocol supports multiple logical networks on a single physical network, allowing the network to exist in multiple regions. See zone .
