4) configure the serial port of the Cisco router and test the connectivity with the superior Router
Similar to the Ethernet port configuration method, you must specify the bandwidth and package Encapsulation Format. In addition, disable the
MAC table: 1. The vswitch uses the MAC table to implement targeted data forwarding and improve efficiency. 2. in actual network applications, it is convenient for management personnel to troubleshoot the data forwarding process of network cables unicast: Check the MAC table with entries: targeted Forwarding (but when the source MAC and target MAC are the same port, discard-MAC filter) www.2cto.com has no entries: Spread the broadcast to all other ports in this segment, which are the same as tho
systems of Cisco router IOS, which may expose sensitive information. This vulnerability allows a low-level user (for example, a user who does not know the 'enable' password) to use the system to view some information, in theory, this information should be visible only to users who know the 'enable' password. This information includes the access control list and other content. Generally, after logging on to a lower-level user (level 1), use "show? "Only a part of the show command list can be see

3. Protect the vro password. In the backup vro security settings file, even if the password is stored in encrypted form, the plaintext of the password may still be cracked. Once the password is leaked, the network is completely insecure.
4. Check the router diagnostic information.
5. The current user list of the vro is blocked. The command to close is no service finger.

We have learned a lot about the basic content of PPPOE. For the application of PPPOE protocol or PPPOE server, many of our friends still feel ethereal. Here we will share the practical experience of the next netizen. In the residential area, the property built a m optical fiber, and then used ROS as a PPPOE server. I don't know the specific network topology and what ROS does. I only know that each household's network cable is connected to the corridor switch. After reading the switch and common

How does a cisco switch find a loop? Loop Problem Solution
How can we intuitively and quickly determine whether a loop exists on a cisco switch? And quickly locate the switch loop? Is this a problem?
Currently, there is no best way to view the loop. You can only view the loop through some information. In addition to the Spanning Tree, there are many preventive loop commands in the cisco environment. The loop will generate a b

Smart power management technology-Principles and power management --I. Terminology1. Low Dropout Regulator)Low-voltage differential Linear Voltage RegulatorAdvantages: good stability, fast load response, and Low Output Ripple
Disadvantage: low efficiency. The input/output voltage difference cannot be too large.
2. DC-DC (Direct Current to Direct Current)

Advantage: High Efficiency and wide input voltage range
Disadvantage: the load response is worse than that of the drop-down list, and
packages, and the terminal package is encapsulated in PPP frame format. If you want to extract the terminal package, you must do the reverse justification of the PPP frame. (2) in a single terminal package, in order to save bandwidth, data from the terminal may be compressed by VJ (Van Jacobson), if you want to do five-tuple attenuation, VJ should be decompressed. (3) The PPP terminal package in the GRE tunnel package may not be complete, the first need to do the terminal package assembly. (

8, local hard disk backup vs. network backupA network backup can cause a certain amount of pressure on network I/O devices. Like hard disk I/O devices, the use of a network for a large number of data transmission can also cause problems. When you consider a network backup, the time that you use to create the backup varies greatly depen

In fact, unicast is a message sent from the source host to another target host, receiving only one target.
First of all, write transceiver Class datagramrecvsender_s, this class is not only send datagrams and receive datagrams, send a folder of all the pictures, a piece of the carry out, receive is in a thread, every file, the activation of an event, event handler to handle this event.
The Class list is:
