4. Frame is the information structure of data link layer
in the 802.3 architecture, the network is an open environment with shared media. The general frame structure of 802.3 is as follows:
pre (7 bytes), SFD (1 byte), DA (6 bytes), SA (6 bytes), len (2 bytes), LLC control information (2-3 bytes), data, pad, CRC (4 bytes)
among them, the number of bytes from Da to pad is 64-1518 bytes
thank you. In order to answer your question, I took out CCNA book again. So I reviewed the concept
I'm engaged in network engineering, and I plan to take the Huawei HCSE exam next year. The question you asked is so professional that maybe we can learn from each other and help each other ~ ~

5. All aspects are very good. CPU, memory and hard disk configuration are the mainstream, and the graphics card is also used. At present, the gt230m, which is stronger in notebook, has the same core parameters as gt240m, but the frequency is a little lower. It is a powerful model in notebook
6. The cost performance of this notebook is very good, specific configuration for you to say: Color: Black CPU: core al core P8700 main frequency 2.53GHz hard disk: 320GB memory: 2GB DDR3 generation is very good graphics card: n card gt230 512MB independent video memory with Bluetooth 2.10 version compared with ordinary Bluetooth transmission speed will be faster price: 6699
7. Introction: Although routers and wireless routers are very popular and convenient for everyone to use, there are still many friends who have just contacted routers and don't know how to set up routers. After all, they are not plug-in and ready to use just like non managed switches. However, manufacturers usually provide instructions, but some of them are not concise enough and too complex. Although some of them provide fool like installation guides, they obviously can't embody the customization of settings. Today, we use the most simple and easy to understand way to express, hope to help rookie friends
1. After the TP-LINK wireless router is wired, enter 192.168.1.1 in ie, and the user name and password are admin by default. After confirming, enter the above setting interface
after opening the interface, a small page of setting wizard will pop up. If the user has certain experience, he or she will tick "next login will not automatically pop up Wizard" to directly set other detailed items. However, I suggest that ordinary users press the next step to set up a simple wizard, which is convenient and simple
click next for simple setup
2. Generally, ASDL dial-up Internet users choose the first PPPoE to set the next step. But if you are in the LAN or through other special network connections (such as video broadband, Internet access through other computers, etc.), you can choose the following two "Ethernet Broadband" to set up the next step. Here, let's first explain the ADSL dial-up settings. The following two items will be explained later. Go to the ADSL dial-up account and password input interface, input the user's Internet account and password provided by the network service provider according to the literal prompt, and then directly press next
3. Next, we can see four parameters: wireless status, SSID, frequency band and mode. Users who can't detect the wireless signal should pay attention to whether their router's wireless state is on
users can modify and add SSID according to their own preferences. This item only needs the identification name of the connected device after searching for the connected device ring wireless connection
in addition, when we pull down the frequency band, we can see that there are 13 digital choices. The setting here is only the frequency band of the wireless signal you are routing. If you have multiple wireless routes nearby, you can set other frequency bands here to avoid conflicts on some wireless connections
next, when the mode option is pulled down, we can see several basic wireless connection modes of TP-LINK wireless routing. The maximum working rate of 11Mbps (802.11b) is 11Mbps; 54Mbps (802.11g) works at a maximum rate of 54Mbps and is also downward compatible with 11Mbps In the TP-LINK wireless routing procts, there are also some unique 108mbps working modes of speedshow series
4. Next, I will briefly introce the page and setting parameters of each setting option
first of all, here is the running status of the first option. Just now, our settings for TP-LINK wireless routing are reflected in the above. If you are an ADSL dial-up Internet user, you can directly connect to the network by pressing the connection on the page here. If you are an Ethernet broadband user, you can connect to the Internet through dynamic IP or fixed IP connection. The corresponding information will also appear here
5. In the LAN port setting of network parameters, we just need to keep the default setting. If you know something about the network, you can also set the IP address and subnet mask according to your preference. As long as you don't conflict with the IP of other workstations, it's basically no big problem. Remember to press save after modifying and restart the router
note: when the LAN port IP parameters (including IP address and subnet mask) change, in order to ensure the normal operation of the DHCP server, ensure that the address pool and static address set in the DHCP server are in the same network segment as the new LAN port IP, and restart the router
6. Basically, TP-LINK provides seven ways to connect to the external network. Now, most family users use ADSL dial-up to access the Internet. I will mainly introce the ADSL dial-up settings
first of all, we choose PPPoE for WAN connection type. Here we can see that there are several familiar and basic setting options. Internet account and password as mentioned before, enter the user's Internet account and password provided by the network service provider
next, there are three options: normal mode, special dialing mode 1 and special dialing mode 2. Among them, the normal mode is standard dial-up, special 1 is to crack the version of Xi'an star speed, special 2 is to crack the version of Hubei star speed, and the normal mode is not used in your region (some routes and special 3 is to crack the version of Jiangxi star speed)
next, there are four corresponding connection modes: 1. Connect on demand, and connect automatically when there is access. 2. Automatic connection, automatic connection after startup and disconnection. In turn on the computer and turn off the computer will automatically connect to the network and disconnect the network. 3. Timing connection, automatic connection in a specified period of time. 4. Manual connection, manually connected by the user. There is no big difference with the first one. The only difference is that the user has to press the connection button below to dial the Internet
7. In MAC address cloning, the interface here is also very simple. A restore factory Mac and a clone MAC address of the two buttons. Basically, just keep the default settings. What needs to be specially explained here is that some network operators will use some means to control the routing to connect multiple computers to the Internet. At this time, each user can clone the MAC address to crack it (not necessarily effective)
8. Now we come to the key point of TP-LINK wireless routing. In the wireless parameters, we can set some parameters such as wireless network link security. I will not repeat the SSID, frequency band and mode. Users who don't understand can refer to the wireless settings section of the previous setup wizard
to enable the wireless network function and allow SSID broadcast, it is recommended that users with wireless network connection requirements check it. Turn on the bridge function. If there is no special requirement, don't check it. It's a bridge function
as for turning on the security settings, I don't think I need to say much about it. You must check it for the first time. There are three security types: WEP, WPA / WPA2, wpa-psk / wpa2-psk
let's talk about WEP settings first. There are three security options here: automatic selection (use open system or shared key mode automatically according to host request), open system (use open system mode) and shared key (use shared key mode)
WPA / WPA2 is a WPA or WPA2 mode in which radius server is used for identity authentication and key is obtained. In WPA / WPA2 or wpa-psk / wpa2-psk, the encryption methods are the same, including automatic selection, TKIP and AES
wpa-psk / wpa2-psk (shared key based WPA mode). The setting here is similar to the previous WPA / WPA2. Note that the PSK password here is the initial password of wpa-psk / wpa2-psk, with a minimum of 8 characters and a maximum of 63 characters
9. Wireless network MAC address filtering settings. You can use the MAC address filtering function of this page to control the access of the host in the wireless network. If you have enabled the MAC address filtering function of the wireless network, and the filtering rule has selected "prohibit MAC addresses other than the effective rules in the list from accessing the wireless network", and there is no effective entry in the filtering list, then no host can access the wireless network
10. After setting the wireless parameters, we can go back to the DHCP service settings in the basic settings page of all series of TP-LINK routing
TCP / IP protocol settings include IP address, subnet mask, gateway, and DNS server. It is not easy to configure TCP / IP protocol for all computers in your LAN. DHCP server provides this function. If you use the DHCP server function of TP-LINK router, you can let the DHCP server automatically configure the TCP / IP protocol of each computer in the LAN for you
generally, the user can keep the default settings, as shown in the figure above. Here, it is suggested that the DNS server address provided by the user in the network provider should be filled in the DNS server, which is helpful for the stable and fast network connection
11. In the client list of the DHCP server, users can see the assigned IP address, subnet mask, gateway, DNS server, etc
12. Static address assignment setting: in order to facilitate you to control the IP address of computers in the LAN, TP-LINK router has built-in static address assignment function. Static address allocation table can reserve static IP address for computer with specified MAC address. After that, when the computer requests the DHCP server to obtain the IP address, the DHCP server will assign it the reserved IP address
13. If users have higher requirements for network services (such as BT download), they can set them one by one in the forwarding rules. The virtual server defines a service port, and all service requests on this port will be relocated to the server in the LAN specified by the IP address
service port: WAN service port, that is, the service port provided by router to WAN. You can enter a port number or a port segment, such as 6001-6008
IP address: the IP address of the computer acting as the server in the LAN
protocol: the protocol used by the server
enable: the rules set in this entry will not take effect until this item is selected
the drop-down list of common service ports lists some common service ports, from which you can select the service you need, and then click this button to fill the service port in the virtual server list above
14. Some programs need multiple connections, such as Internet games, video conference, Internet phone, etc. Due to the existence of firewall, these programs can not work under simple NAT routing. Special applications enable some of these applications to work under NAT routing
trigger port: the port number used to trigger the application
trigger protocol: the type of protocol used to trigger an application
open port: when the trigger port is detected, the packets going to the intranet on this port will be allowed to pass through the firewall, so that the corresponding special applications can work normally under NAT routing. You can enter up to 5 groups of ports (or port segments), and each group of ports must be separated by the English symbol ","
15. In some special cases, a computer in the local area network needs to be completely exposed to the wan to realize two-way communication. At this time, the computer can be set as the DMZ host Note: after setting the DMZ host, the firewall settings related to the IP will be changed
1. After the TP-LINK wireless router is wired, enter 192.168.1.1 in ie, and the user name and password are admin by default. After confirming, enter the above setting interface
after opening the interface, a small page of setting wizard will pop up. If the user has certain experience, he or she will tick "next login will not automatically pop up Wizard" to directly set other detailed items. However, I suggest that ordinary users press the next step to set up a simple wizard, which is convenient and simple
click next for simple setup
2. Generally, ASDL dial-up Internet users choose the first PPPoE to set the next step. But if you are in the LAN or through other special network connections (such as video broadband, Internet access through other computers, etc.), you can choose the following two "Ethernet Broadband" to set up the next step. Here, let's first explain the ADSL dial-up settings. The following two items will be explained later. Go to the ADSL dial-up account and password input interface, input the user's Internet account and password provided by the network service provider according to the literal prompt, and then directly press next
3. Next, we can see four parameters: wireless status, SSID, frequency band and mode. Users who can't detect the wireless signal should pay attention to whether their router's wireless state is on
users can modify and add SSID according to their own preferences. This item only needs the identification name of the connected device after searching for the connected device ring wireless connection
in addition, when we pull down the frequency band, we can see that there are 13 digital choices. The setting here is only the frequency band of the wireless signal you are routing.

9. Wireless network MAC address filtering settings. You can use the MAC address filtering function of this page to control the access of the host in the wireless network. If you have enabled the MAC address filtering function of the wireless network, and the filtering rule has selected "prohibit MAC addresses other than the effective rules in the list from accessing the wireless network", and there is no effective entry in the filtering list, then no host can access the wireless network
10. After setting the wireless parameters, we can go back to the DHCP service settings in the basic settings page of all series of TP-LINK routing
