ip sla configuration

First, the automatic acquisition of IPThere is only one situation where you can automatically get an IP address, which is the DHCP service in the network environment where your Linux resides. As long as your real machine can get IP automatically, then Linux installed on the virtual machine can also get IP automatically. The method is simple, just need to run a co

We all know that you must be careful when configuring routes on routers and layer-3 switches. There must be no error in IP addresses and subnet masks. Recently, when I conduct a network debugging, I found that improper configuration of the local IP address also causes route exceptions. Fault description My company often needs to debug the network. Recently, the c

Different Linux distribution a network adapter to configure multiple IP method is basically the same, but the edited file is different. 1. Ubuntu Configuration Multiple IP Edit/etc/network/interfaces:sudo Vi/etc/network/interfaces, and then follow interfaces eth0 configuration to add interfaces to eth0:0. For example:

Apache Configuration Virtual Host support 3 ways: IP-based virtual host configuration, Port-based virtual host configuration, domain-based virtual host configuration. This essay records your IP-based virtual host configuration.If

Research on the PPP process at the RP Port PPP Negotiation process as shown in the following: In the process of establishing PPP, pdsn need and FAAA. HAAA Interaction. At the same time in the packet data business process This interaction more frequent, introduced as follows, there are two cases, simple IP, mobile IP: Simple IP Similar to

energy management system EMS to control the operation of the power grid. in the case of an accident, the dispatcher needs to provide a backup EMS workstation in the distance, prevent scheduling paralysis and grid resolution from fire and other accidents, and ensure safe, economical, and high-quality operation of the grid. The remote backup workstation is located three kilometers away from the central scheduling and has a long distance. The scheme decides to connect the two ends with a Cisco2610

Sometimes, in our intranet service, if you do not want to use the routing function, but also want to let some servers across the network services, then, it is necessary to configure the server network card multiple IP address, so that it can provide multiple network access, then the Linux how to implement, today to share.Operation Steps1.

1, first we open the Start menu, find the Control Panel options. Click the "Network and Internet" option, locate the "Network and Sharing Center" option and click, and then find the "Change adapter Settings" option Click to enter (all of the above is done under Win7, and other operating systems may be slightly different). 2, then find the way we connect the network, if the use of wired connection, we choose "Local Connection", if the use of wireless connection, we choose "Wireless network conne
