Based on MAC address implementation , dynamic VLAN TRUNK ( trunk ): uses a special encapsulation mechanism to transfer data from multiple VLANs . =========================================================== =============== Enable enter privileged mode Encapsulation frame-relay clockrate 64000 A LAN standard that can run at speeds up to 200 Mb/s and use token transfer media access technology on fiber optic cable. For redundancy, a double loop structure can be used. The device has the hardware address of all devices on the internetwork. The server will then dynamically allocate the used VLANs . =========================================================== =============== Vlan database enters vlan configuration mode vtp domain configures VTP domain name vtp password configures VTP password Store and forward , re-calculates the frame's FCS original frame FCS compared , to decide to forward or discard . Freedom fragment forward , only the first detection frame 64 bytes , determining the integrity of the frame . FRAME-RELAY LMI Signaling ABM Asynchronous Balance Mode ---- ABM is an HDLC ( or a protocol derived from it ) communication technology that supports peer-to-peer, point-to-point communication between two stations when two stations can start transmitting. Direct forwarding : fast , but can not ensure the correctness of the forwarded frame . 1. Router 2. Routing implementation path selection ( routing decision ). Routing Table 3. WAN access . 4. Router broadcast domain division ( interruption ). B (config-if) #ip nat inside configured S0 interface inside the network A (config) #inte s 1 enters s 1 interface eBGP External Border Gateway Protocol (External Border Gateway Protocol) is used in different autonomous administrative weight ( administrative weights ) value for a given network administrator specified hierarchical network links. can CGMP Cisco Group Management Protocol (Cisco Group Management Protocol): made Cisco a proprietary protocol developed. The router uses CGMP to send multicast member commands to the Catalyst switch. Fast switching ( fast switching ) that utilizes a route cache to speed up packet switching through a router Config-register 0x2142 modify the startup configuration key Dynamic control of the measure, ACR varies between minimum cell rate (MCR) and peak cell rate (PCR) . See =========================================================== =============== It does not indicate an error and can be intentional. See fragmentation . binary ( binary ) by 1 and 0 two methods of counting characters. Binary count is made for all information =========================================================== =============== R14(config)#dialer-list 9 protocol ip list 1 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 . Configure virtual loopback interface ( loopback interface defaults to UP state ) inerface loopback? Create a loopback interface DNS Domain Name System (Domain Name System) is used to resolve host names to IP addresses. Grafing ( transplanted ) to activate a pruning process had been frozen interface process. It is sent to the router There is traffic successfully reaching the destination. This usually occurs in networks that combine inefficient or poorly cached routers with poor packet drop or ABR congestion feedback mechanisms. Register cofiguration ( Configuration Register ) ----- in hardware or software stored in a 16 -bit value may be configurable, it is determined during initialization Cisco router functions. In hardware, the bit position is set using a jumper. In software, it is set by the specified special bit pattern, which is configured with a hexadecimal value along with the configuration command to set the boot options.
