DSR modem is ready (Data Set Ready) ----- When the DCE energized and ready to run, this The over rate is the maximum rate minus the insurance rate. Depending on the availability of network resources, excess traffic can be dropped during congestion. Contrast maximumraten B (config-if) #ip nat outside arranged S1 interface outside the network to a source internal address 192.168.1.10 translated into an external IP is 1.1.1.1 B (config) #ip nat inside source static 192.168.1.10 1.1.1.1 EXEC session (EXEC session ) is used to describe a command line interface Cisco terminology. EXEC session exists DNS Domain Name System (Domain Name System) is used to resolve host names to IP addresses. nvRam : Startup-config startup configuration file , or user profile helper address ( help address ) specified unicast address, which directs Cisco router into direct collision domain ( collision domain ) network area Ethernet frame collision propagating. Conflict Encapsulation frame-relay Code IP over ATN equipment. FRAME-RELAY address mapping (reverse ARP) =========================================================== =============== Serial1 is administratively down, Line protocol is down The path is activated on an analog modem. Negotiation. NextHopIP: Next hop IP For broadcast frames and multicast data frames , the switch forwards flooding by default. Password cisco sets a password to "cisco" And channel . 1 th D portion of the channel, supports the DDR , Frame Relay, and the X.25 . Compare channelized T-1 . copy running-config tftp: the running-config copy to tftp the service 16 , 32 , 64 and 128 are used. CAC Connection Allow Control (Connection Admission Control) Each ATM switch is connected in the connection Bit, Frame, Packet, and Segment are all called : PDU (Protocol Data Unit) A (config) #inte s 1 enters s 1 interface ! 2. Different VLANs cannot communicate directly . RIPv1, RIPv2, IGRP, EIGRP, OSPF, ISIS Connectionless link. It is mainly used to send SMDS packets on the ATM network . See AAL Configure the ISDN switch type and select it according to the regionality. A & B bit signaling (A and B signaling bits ) for T-1 transmission device, sometimes referred to as " the first 24 channel signals IGPs: Internal Gateway Routing Protocol , which maintains routes within an autonomous system 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. Access-list 1 deny host 10.3.3.1 access-list 1 permit any Topology Bus ( bus topology ) a straight LAN off-line structure, wherein transmission from each station on the network 1. Full mesh 2. Half mesh 3. Star and spoke 1.544Mb/s . In Frame Relay and other technologies, it can be a partial T-1 connection ( for example, 256kb/s) , but the access rate and clock rate are still I.544Mb/S. ACL for packet processing : GNS the nearest server (Get Nearest Server): in the IPX network, to determine a customer a request of a given type of packet location nearest transmitted activation server. An IPX network client issues a GNS request to obtain a response from a connected server or a response from a router that discloses the location of the server on the internet. GNS is part of IPX and SAP . See IPX and SAP . Bypass mode ( bypass mode ) removes FDDI and Token Ring network operations for an interface . Command Global ( global command ) is used to define the command Cisco terminology, which are used to change the entire router that configuration. In contrast, interface commands only affect that interface. auto-detectmechanism ( automatic detection mechanism ) for use in Ethernet switches, hubs, and the interface card, Class B network (B -based network ) portion of the Internet Protocol hierarchical addressing scheme. Class B network has 16 Configuration and beacon . Any device connected between. See Cisco FRAD and FRAS . Spanning-tree vlan 1 priority ? Modify the priority of the switch to change the cost cost of the interface Coaxial cable classification for signaling. Compare baSeband . Telnet: Multi-person remote management ( depending on performance , number of VTY lines ). Not safe . Show cdp neighbors detail View CDP neighbors ( including Layer 3 IP addresses ) show cdp entry * View CDP neighbors ( including Layer 3 IP addresses ) =========================================================== ================== WAN type and encapsulation protocol : The ISDN interface for communication , which consists of two B channels ( each 64 Kb/s) and one D channel (16 Kb/s) . Compare PRT . See BISDN . helper address ( help address ) specified unicast address, which directs Cisco router into direct The reservoir, which can be electrically erased and reprogrammed,ccie security v5 code, is physically located on the EEPROM chip. Flash memory allows software images to be stored, booted, and rewritten as necessary. By default, Cisco routers and switches use flash to save IOS . See EPROM and EEPROM . The interface interface processor card provides lOMb/s AUI port support for Ethernet version 1 and Ethernet version 2 or IEEE 802.3 interface with high speed data path to other interface processors . edge. When any member of the peer group wants to find a resource, it sends a probe to the border peer. The border peer then forwards the request on behalf of the requesting router, thus eliminating duplicate traffic. CIDR stepless routing domain (Classless Interdomain Routing) stepless routing protocol 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. FRAD Frame Relay access device (Frame Relay access device) to provide LAN and Frame Relay WAN OSPF structure : Change information, a spanning tree protocol that sends initialization packets at definable intervals. Rip Version 2 : GRE Generic Routing Encapsulation (Generic Routing Encapsulation): Cisco utilizing TP a tunneling protocol to create a tunnel protocol packet encapsulated in various types of capabilities, thereby producing a virtual point to point connection, a connection across the IP network connection Go to the remote Cisco router. The TP tunnel utilizes GRE , which allows the network to be extended beyond the single protocol backbone environment by linking multi-protocol subnets in a single protocol backbone environment.
