Let’s make a distinction between frame and packet before moving forward as these terms are often used rather loosely. They are merely different representations of the same MAC address. A Microsoft Windows system would list a MAC address as 12-34-56-78-9A-BC whereas a Cisco switch would list it as 1234.5678.9abc. Ethernet addresses, also known as MAC (Media Access Control) addresses, are 6 bytes or 48 bits in length, typically written in hexadecimal form. If you are looking to group a pivot table text field into categories which don't currently exist within your data, you may need to look at creating 'Calculated Items' which you can learn on our Excel Professional course.The ultimate goal of switches is to carry frames from the source to the appropriate destination based on the destination Ethernet address in the frame header. Once to the Rows field and one to the Values.ĭates are easy to group in a pivot table, as Excel offers different options, e.g. The thing to remember is that you are adding the Age field twice to the pivot table. Now you can add the age field again, to the value section, plus any other relevant fields. Here we see the grouping options below with an interval range of 10.
This will give you the full age range here, for example from 20 to 60 years.Ĭlick on a single year entry and use the menu to select the 'Group Field' or 'Group Selection' option on the PivotTable Options/Analyse tab (depending on your version of Excel). We now want to group them by age range so it gives us the frequency of particular age ranges from the lowest to the highest.įirst of all, insert a Pivot table as normal against this data and add the 'Age' field to the Row section. Their age has been calculated from the DOB of the person and the current date. In the example below, there is a list of participants, all aged between 20 and 60. anyone from 1 to 10, 11 to 20, 21 to 30, etc.Įxample on how to group numbers in an Excel pivot table For example, you can group them by age range - e.g. You could group data by a specified range or percentage as well. For example, you can group all your sales by sales region or division, or group your data by numbers such as Division 1 to 8. We all know Pivot Tables are a great feature in Excel, so if you are already familiar with the basics you may get to a position where you want to group data in pivots.
