Hello,
When looking at the spanning-tree summary page, what does it mean when counters increment under the "Forwarding and STP active" column?
For example for VLAN0005 and 0006, I saw that the counters increment by 1 over the weekend. What does this tell me?

Hi,
it should be number of active ports in each VLAN (access ports and trunks which permitted VLAN).
Try to type command "show spanning-tree" and if you count number of interfaces for each VLAN you will get number in show spanning-tree summary
