Cisco Systems (CSCO 0.29%) reports earnings on Wednesday this week. In this video, Motley Fool senior technology analyst Eric Bleeker tells investors why this is going to be the week's big notable technology stock to report earnings. Simply put, Cisco is still the most notable bellwether across networking and gives good insight into broader IT spending.  He also covers the performance of some of Cisco's peers this earnings season and how several have taken beatings due to weak growth. Lastly, Eric notes that while company guidance is always important, it's been the largest determining factor in how tech companies performed after earnings across this season. He suggests that if there's one number that will drive the reaction to Cisco's earnings, forward guidance will be the area taking center stage when investors react to Cisco's earnings on Wednesday night.
