For a long time did not write blog, today to write an article to fill the number, ha ...Now let's use a TFTP server to backup and restore Cisco device Files!!The tools we want to prepare are:Cisco TFTP tool (please download the attachment)GNS3/CRT (this please find your own Niang)When you have the tools on top, we're going to start!1, configure GNS3 Road by the TFTP device connected:Below we will prepare the following three (routing, switch 2 layer, cloud) in the GNS3 and connect them together.6

easier for them to work with data from all parts of the worksheet, or to use the same cell's data in multiple functions. You can also reference cells from different worksheets in the same workbook, or even refer to data in other workbooks. Depending on the position of the cell where the formula is located, we can refer to the three types of reference as relative, absolute, and mixed. As an example of the formula "=sum (A2:E2)" That is stored in cell F2, the reference in the formula changes to F

1. Select the cells that you want to set up data validation, such as the E3 cell here. Open the Data Validation dialog box and set the validation criteria on the Settings tab. Here, in the Allow Drop-down list, select the Custom option, enter the formula =isnumber (E3) in the Formula text box, as shown in Figure 1, and set the cell input prompt in the Input Information tab. As shown in Figure 2, the error m
