sh spanning-tee summary shows us some details that are configured on the protocol. In this demonstration, discovering the amount of VLAN's there are. We'll add some more VLAN's and then check again.
sh vlan brief is the main way to discover VLAN information.
I have added 4 more VLAN's on the switch. To find the procedure of adding and configuring VLAN's, see this page.
Now we can see the added VLAN's, the total of 5.
