Routing Table => Best Route Ping 1.1.1.1 detects the validity of the interface VLAN features : cable range ( range of cables ) in the extended AppleTalk network, the existing nodes on the network so that Protocols : TCP The CISCO 1900 series switches use free shard forwarding to forward this forwarding method by default. A recognized serial interface processor that provides four or eight high-speed serial interfaces. If the neighbor and passive-interface are configured at the same time , then the neighbor will not be restricted by the passive-interface .

Encryption ( encryption ) converting the information into a form clutter to effectively disguise, so as to prevent an authorized end Free Fragment Forwarding (cisco private technology ): between pass-through forwarding and storage forwarding performance .

AFI privilege and format identifier (Authority and Format Identifier) ​​A part of the NSAP ATM address " The main explanation is B , C words that begin with. (ChinaITLab) 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. The destination hardware address of a frame, then look up the address in the filter table established by the switch, and then only send the frame to the port of the found hardware address, and the other ports cannot see the frame. 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 .

It has no overhead, try its best =========================================================== =============== To understanding COmposite metric ( complex metrics ) with IGRP and EIGRP use with such routing protocol, It consists of a router or access server or several routers or access servers, using inter-access tables and other methods to ensure the security of the private network. dixed configuration router ( fixed router ) can not be used to upgrade any new interfaces of the router. FTP file transfer protocol (File Transfer Protocol): used to transfer files between network nodes of TCP / IP VLAN; all switches in the end-to-end \VLAN understand all configured VLANs . End-to-end VLANs are configured to allow membership based on functions, projects, departments, and so on. 5.ExChange 6.Loading 7.Full Other bridges operate the same spanning tree algorithm, but allow packet encapsulation to be transmitted over a Frame Relay network. Node group. A direct broadcast is indicated by its broadcast address, which is a destination subnet address where all bits are one . BIP bit interleaved parity (Bit Interleaved Parity) ATM are used to monitor the link on the error Bits are used to define the network and 16 bits are used to define hosts on the network. Network layer : routing ( path selection ), logical address (IP) Packet " The main explanation is F , G , H vocabulary beginning. Typically specified by the network administrator and used by routing protocols to compare different routes through an internetwork. The routing protocol uses the cost value to select the best path to a destination : the lowest cost identification best path. See routing metnC . 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 . The client's local broadcast request is changed by unicasting the service to the server.=========================================================== =============== reload reload Router ( restart ) The mode boots the device with an operating system.
