See UTR Data Terminal Ready (Data Terminal Ready) ----- an activated with DCE communication ACL for packet processing : ------------------------------------------------- group. Because they do not forward broadcast frames, the broadcast domain is usually surrounded by routers. Access server ( access server ) is the so-called " network access server " , it is a communication process, through the network Ip route 4.0.0.0 255.0.0.0 s0 Bypass mode ( bypass mode ) removes FDDI and Token Ring network operations for an interface . Equipment and Tnter have jointly improved. Ethernet is similar to the TEEE802.3 family of standards and uses CSMA/CD to operate at lOMb/s rates on various types of cables . Also known as DIX (Digital/Intel/Xerox) Ethernet. See The IP address is converted to a MAC address. See RARP . Serial1 is administratively down, Line protocol is down Grafing ( transplanted ) to activate a pruning process had been frozen interface process. It is sent to the router frame types ( frame type ) the LAN in a frame is used to determine how to put on the local network. Ethernet Media type : twisted pair , coaxial cable , fiber WAN : The CISCO 1900 series switches use free shard forwarding to forward this forwarding method by default. Network 192.168.1.0 0.0.0.255 area 0 Medium, indicating the beginning and end of each character. Compare isochronous transmission . PAP: Two handshakes , the password is transmitted in clear text.

A Cisco hierarchical network. The core layer quickly passes packets to the distribution layer device. No packet filtering is performed at this level. Ping 1.1.1.1 detects the validity of the interface Routers in the same autonomous system are able to learn to advertise related routes to each other . Interface s 1 encapsulation frame-relay 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. The requested VCC determines the likelihood of a path containing the appropriate bandwidth. Use more than one metric to find the best path to a remote network. By default, both IGRP and EIGRP use the bandwidth and latency of the line. However , the reliability of the Maximum Transmission Unit (MTU) , load, and link can also be used . =========================================================== ================ Select the metric for the route : ATM ATM (Asynchronous Transfer Mode) by a fixed-length 53 -byte element identifier FECN: Forward Explicit Congestion Notice control direct VCC ( control direct VCC) ----- Phase I LAN one of three emulation control connection defined in the ATM by \ a LEG to a LES established bi-directional virtual control connection (the VCC) .
