For redundancy, a double loop structure can be used. dynamic entries ( dynamic entries ) for the first 2 layer and 3 to create a hardware device address dynamically layer Any device connected between. See Cisco FRAD and FRAS . Medium, indicating the beginning and end of each character. Compare isochronous transmission . Source : 10.3.3.1 OSI seven-layer network model : Protocol data unit Show interfaces fastethernet 0/1 switchport Standard access control list : Detect only the access control list of the source address extension : source address , destination address , protocol , port number Area ( Area -----) rather than physical segment of a set of logical ( based CLNS , DECnet , or OSPF) and their attached devices. Areas typically use routers to connect to other areas to create an autonomous system. See autonomous system . A collection of self-management systems that do not rely on information received from other systems or groups. This routing algorithm group repeats the number of hops in a given route, requiring each router to send its complete updated routing table, but only to its neighbors. This routing algorithm has a tendency to generate loops, but is simpler than the link state algorithm. See link-state routing al-gorithm and SPF . Set the dial number R14(config)#interface bri 0 The device has the hardware address of all devices on the internetwork. The server will then dynamically allocate the used VLANs . congestion collapse ( congestion collapse ) the ATM results in the packet network due to retransmission, wherein little or no A logical collection of information. IP datagrams have become the main unit of information for the Internet. In the OSI layers reference model, the term cell (Cell) , frame (Frame) , the message (message) and the segment (segment) also define these logical information groupings. bridging loop ( bridging loops ) bridged network, to a network if there is more than one link and STP FRAS FR access support (Frame Relay Access Support) ----- Cisco IOS a characteristic of the software, which allows the SDLC , Ethernet, Token Ring and Frame Relay connections IBM upper frame relay network equipment can Other AS AS (autonomous system) a group of networks under the management of another, they share the same broadcast domain ( Radio City ) receiving apparatus of any broadcast frame sent from a device in the device group 1.

(Default config regcode) 100Mbps 19 The bit set in the frame when the frame relay network encounters a congestion path. Receiving a DTE with a BECN frame can require the advanced protocol to take the necessary flow control measures. Compare FECN . Configure a password for the console port : 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.

This is an extended version of SF . See SF . Access server ( access server ) is the so-called " network access server " , it is a communication process, through the network B(config)#inte s 0 convergence ( convergence ) Internet in all routers update their routing tables and create a consistent It can be provided by a secondary router added to a remote network.
