1. The steps of an input and output: 1) wait for the data to be ready; 2) the data is moved; 2) there are 5 kinds of Imax O models; 1) Block the Imax O model: the application calls an Imax O function, causing the application to block and wait for the data to be ready. If the data is not ready, wait. The data is ready, from the inside

Experiment name: building a stable OSPF campus network experiment topology: (unified topology diagram) experiment requirements: 1. If shown, configure the interface IP address, and there is a loopback 0 on each router with the IP address: 10.10.x.x/2
F5 has a lot of products and modules, but what I am most familiar with is that LTM,LTM is not good at learning, and I hate few books when I use them. The requirement is to restore the configuration from the host to the standby without affecting the host running online.

Remember a company network failure troubleshooting was supposed to be very good on Monday, just sat on the station for less than half an hour, the company suddenly cut off the network, at this time, I am a little messy! The following is the troubleshooting process 1. First of all, I look at the IP address of the local computer, disable startup, and find that the IP address can still be obtained.
OSPF triggered update means that in an OSPF area, when the interface down of one of the routers falls down or the link state information changes, it will send a multicast packet to declare its new state. This process is called triggered update. The process of triggering the update amount is: 1. The router discovers the link.
In fact, the virtual human has written vCAC6.x series graphics and text documents before, but now that Update has reached vRealizeAutomation Center 6.2.1, then write another vRA 6.2.1 series. In the first part, I would like to talk about such as
