The fabric capacity is the aggregated maximum speed of all 24 ports. The 8024f has 24 SFP+ ports that are 10Gb. This means the equation come out to be: 24 (ports) * 2 (duplex) * 10(Gbps) = 480Gbps. This indicates that the switch is non blocking and can handle the total bandwidth of all ports. The switch does have a utilization page you can view. The page provides the following information: [IMAGE] The Open Manage network manager also offers the ability to track Bandwidth capacity utilization.

Hello^^ Actually the question what I say is different from other questions that people make inquires. Nevertheless, I want to know my question because there's no person who teach me...  From old times, I wondered how to measure traffic That is, I want to know measuring "Fabric Capacity" I can easily see "Fabric Capacity" in the datasheet.  In the Dell 8024F datasheet, I found below one. [IMAGE] There's "Fabric Capacity up to 480Gbps". I believe 480Gbps means traffic capacity, right?  When we choose Router or Switch, we always refer datasheet.    As I mentioned to you continually, the idea what I want to is below thing. How to know and how to measure my traffic?  Maybe in order to measure capacity, there's a something program or another method?  Thank you.
