(Universal File Transfer Protocol), etc. The TCP/IP protocol is independent of the low-level data link layer and the physical layer, which is also an important feature of TCP/IP First layer: Physical layer (Physicallayer)Specifies the mechanical, electrical, functional, and process characteristics of the communication equipment used to establish, maintain and dismantle physical link connections. Specifically, the mechanical characteristics of the network connection required to plug-in specifica

The question about the Cisco router interface is described in the following four steps. Based on the demonstration in the image, I believe that we should be able to clearly understand the question about the interface. You can configure a serial interface through a virtual terminal. to configure a serial interface, follow these steps: 1. In Global mode, enter the command "interface serial 0" to enter the serial interface configuration mode. 2. Each connected serial interface must have an IP addre

This experiment configures and monitors the IP Address Access Control List, including the list of standard, extended, and named IP addresses.1. Tutorial PurposeThrough this experiment, you can master the following skills:● Configure the standard IP Address Access Control List;● Configure the Extended IP Address Access Control List;● Configure the standard IP Address Access Control List;● Configure the name of the Extended IP Address Access Control List;● Reference the IP address access control l

The rules related to short message sending and receiving discussed mainly include GSM 03.38, GSM 03.40, and GSM 07.05. The first two focuses on the technical implementation of SMS (including the encoding method), the latter sets out the DTE-DCE interface standard of SMS (

Communication between peer layers is achieved at the same layer of different nodes according to the protocol. The first layer: Physical Layer (PhysicalLayer), which specifies the mechanical, electrical, functional, and process characteristics of communication equipment for establishing, maintaining, and removing physical link connections. Specifically, the mecha

You can configure a serial interface through a virtual terminal. to configure a serial interface, follow these steps: 1. In Global mode, enter the command "interface serial 0" to enter the serial interface configuration mode. 2. Each connected serial interface must have an IP address and subnet mask to forward IP packets, in interface configuration mode, enter the "ip address 3. If the serial interface is connected to a DCE device, we also need to co

second. A long time ago, 300bps was fast, and now the computer can handle up to 430,800 of the RS-232 rate. The units that represent the baud rate are also KPBS and mbps,1kps=1000bps and 1mbps=1000kbps. In general, when a serial device is mentioned, it is often said that it may be a data communication device-DCE (Communications equipment) or a data terminal device-dte (the information Terminal equipment).

off. The speed of serial data is usually expressed in bytes bits-per-second (bps) or baud rate (baud) transmitted per second. This value represents the number of 0 and 1 sent out per second. A long time ago, 300bps was fast, and now the computer can handle up to 430,800 RS-232 rate. The unit that represents the baud rate also has KPBS and mbps,1kps=1000bps and 1mbps=1000kbps. When a serial device is commonly referred to, it is usually said to be a data communication device (-

MODEM, CSU, or DSU to "LOOPBACK" and run the "show int Serial interface-number" command to check whether line protocol is UP, it indicates that the communication board is faulty or the remote router has been shut down. Check whether the SERIAL port connected by the cable is correct. Use "show controllers" to check which cable is connected to which SERIAL port. Type "debug serial interface ", if line protocol does not come up, or the number of activated ports does not increase, it indicates that

physical link connections. Specifically, the mechanical characteristics specify the specifications, sizes, number of pins, and arrangement of connectors required for network connection; the electrical characteristic specifies the signal level, impedance matching, and transmission speed limit on the line when the bit stream is transmitted on the physical connection. The function characteristic refers to assigning the exact signal meaning to each signal first, that is, the function of each line b

The process feature defines a set of Operation Procedures for bit stream transmission using signal lines, it refers to the action series of the DTE and
