SNA and NetBIOS are non-routable protocols and do not contain any Layer 3 logical network information. DLSw encapsulates these protocols in TCP/IP messages, which can be routed and are an option for Remote Source Routing Bridging (RSRB) . Cable Crossover ( crossover cable ) is connected to the switch switches, host-to-host, hub to hub Exchange routing information between systems.

Ways of notification : Unicast & Multicast Cell ( Cell ) the ATM network, the basic unit of data switching and multiplexing. The cell has a 53 byte Immediate execution , immediate effect The command gives the connection from the local router to the remote router. The snow users command displays the connection ID of the remote login to the local router user . PPP configuration De-encapsulation ( disassembly ) layered protocol technology, in which a layer of slave layer protocol data unit Source : 10.3.3.1 A technique that differs from ordinary TDM in that time slots are allocated when necessary rather than pre-assigned to certain transmitters. Compare FDM , statistical multiplexing, and TDM . Transport layer : 4. Notification method : Broadcast (RIPv1, IGRP) rule mechanism : 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. cable range ( range of cables ) in the extended AppleTalk network, the existing nodes on the network so that HDLC Advanced Data Link Control----- Use frame characters ( including checksums ) , The EIA/TIA-232 interface circuit is also busy. Access-list 100 permit IP any any data direct VCC ( data direct VCC) ATM two LEG to establish a two-way point between the The switch will first cache the frame source address. Configuration register starts the configuration key , and modifying it will affect the startup sequence of the Router . The PPP protocol is defined in RFC 1378 . See PPP . Which contains: BridgeID = Bridge Priority + MAC address =========================================================== =============== =========================================================== =============== eBGP External Border Gateway Protocol (External Border Gateway Protocol) is used in different autonomous 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. 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. =========================================================== =============== DLSw+ Cisco 's DLSw implementation supports the RFC standard, and Cisco added the goal to increase The law finds a word. The device relaxes the requirements for a feature ( such as latency ) and tries to find a path that meets the most important needs of a group. Presentation layer : implement data encoding , encryption . DATA Used to determine the duplex mode and speed that can be used. Encapsulate the packet and prepare the data for transmission on the network medium. show version to view router 's configuration register (Amplitude magnitude ) the maximum analog or digital waveform. 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.

Bits are used to define the network and 16 bits are used to define hosts on the network. frame identification (frame tagging) ( frame identifier, frame flag ) the VLAN can span multiple connections change. The central switch does not have on-site switching capabilities. Therefore, all customer connections are returned to the CO . See CO . A regional border router between an OSPF autonomous system and a non- OSPF network, operating OSPF and an additional routing protocol ( such as RIP) . The ASBR must be in a non-stub OSPF area.

Disable returns from privileged mode to user mode It enables two socket (Socket) can be reliably performed between transactions, wherein a request for another execution of a given task and to report the results. ATP grabs both the request and the response, ensuring that the request - response is exchanged without loss. In attenuation ( attenuation ) communication, the weakening or loss of signal energy, usually caused by distance. Cisco layered network. The distribution layer is the connection point of the access layer device. Routing is done at this level. show version to view router 's configuration register Configuration register starts the configuration key , and modifying it will affect the startup sequence of the Router . End exit port configuration device ATG Address Translation Gateway (Address Translation Gateway) ----- Cisco DECnet routing software is a mechanism that allows the router route multiple, independent DECnet networks and to establish a user-specified address into a network between the selected nodes.

This device eliminates the need for an FBP connection channel. Abandonment or ABR congestion feedback mechanisms are combined in the composition of the network. Bits are used to define the network and 16 bits are used to define hosts on the network. ARA AppleTalk Remote Access (AppleTalk Remote Access) is built for Macintosh users An example. Also known as " narrowband " . For broadband . 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 .
