network management protocols

As an Enterprise Network Administrator, our most important task is to ensure the normal operation of the enterprise network. However, among the many network devices, the vro and vswitch are the core devices, its normal status is directly related to the running status of the enterprise network. Large and medium-sized en

Faults are inevitable during network management and O M. If an administrator attempts to build a zero-fault network, it will be futile. There are too many randomness and contingency factors in network faults, not to mention human factors. Therefore, what administrators need to do is to master the

For enterprises and institutions of customers to divide multiple VLAN network management status, in order to better deploy the day easy to network management system, we recommend the use of the Network Bridge mode of monitoring, that is, using dual

Linux Network Management (i)First, Ifconfig commandThe Ifconfig command can display the NIC and IP parameters, which is a more important command in CENTOS6.Examples of Use:1, network card stop and network card start Ifdown (NIC name)Ifup (NIC name) Note the Ifdown command can no longer be used alone in the Xshe

network administrators can use this command to obtain detailed network statistics. The netstat command format is as follows: Netstat [-A] [-E] [-N] [-R] [-S] Frequently Used parameters are: -A: displays the port numbers of all host connections and listeners. -E: displays Ethernet statistics. -N: the address and port are displayed in a digital table. -R: displays route information. -S: displays the status o

Common network security management commands and network security commands : Common network security management Commands include: ping command to determine whether the host is connected, ipconfig to view IP address configuration, and netstat command to view

Analysis of IP network bandwidth management and application optimization requirements With the gradual development of the Internet, the number of online users and business traffic is constantly increasing. In addition to traditional data services, new network applications, such as network phones, online videos, and

WAN connection has many implementation technologies, such as integrated business digital networks and point-to-point protocols. Frame Relay is undoubtedly the most ideal WAN technology for remote connection so far. Frame Relay defines the process of sending data on the public data network, which is suspected of being a high-performance data link layer. It mainly works on the OSI reference model and data lin
