Stinky Toilet Paper...

this is gonna hurt you more than me...
spanning-tree port states... arrrrrrrrrrrrrrgh

after initializing, a switchport always enters the blocking state

blocking:
the port dumps the frames received
dumps frames switched for forwarding from another switch
doesn't learn shit
receives bpdu's

listening:

the port dumps the frames received
dumps frames switched for forwarding from another switch
doesn't learn shit
receives bpdu's

learning:
the port dumps the frames received
dumps frames switched for forwarding from another switch
finally gets off its dead ass and learns addresses
receives bpdu's

forwarding:
receives and forwards frames
forwards frames switched from another port
learns addresses
receives bpdu's

disabled:
doesn't do shit
