high. The advantage of using snapshots is that you can back up data at any time. 8. Local hard disk backup Vs. Network BackupNetwork Backup may put pressure on network I/O devices. Like hard disk I/O devices, using a network to transmit a large amount of data can also cause some problems. When network backup is considered, the backup creation time varies depending on different situations. The best way is to back up the hard disk to the local server. After the backup is complete, copy it to the

Pen name is also large, the motto of the gameToday it is the command of the Cisco switch which is the practice of the work operation, I feel that sometimes it may be necessary to trace the port of which the MAC address belongs to the switching device, and to determine the object quickly, I share my exercise to the lovers who need it.The first thing you need to know is the IP address and account password of the core switch device of your organization.Example: Core switch ip:192.168.11.1, Account:

to conserve storage space, it is common to combine full-volume and incremental backup technology. Obviously, there is a significant shortage of such data backup methods, that is, backup window problems. During the data backup period, the enterprise business needs to temporarily stop the external provision of services. As the volume of enterprise data and data growth accelerates, this window may become more and more lengthy, which is unacceptable for critical business systems. such as banks, tel

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

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.

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? How to solve Loop Problems, cisco 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
