Yes I think that these 2 ports are copnnected to a hub? Can you confirm that please?
Because the destination address for CDP frame is a multicast address and when it coems out from your port 3/3 it will reach the hub and hub will broadcast the frame and it will see port 3/9 as its naighbor and vice versa it will happen when the CDp frame will move out from port 3/9.
Now both the ports are in different vlan so this could be the behaviour is it possible can you configure both the ports into same vlan just to verify what will happen I think one port will go into blocking state.
Can you just make a change for a minute and verify?
I went over to the switch and tried tracing the cable. Not possible without my Probe&Toner which is on loan at the moment. So I come back to the office and turn off portfast (no spanning portfast), and shut, no shut the ports.
If there is indeed a loop on those ports, which it looks like there is, shouldn't spanning-tree put those in blocking state? I guess I know the theory of spanning-tree, but have never put it to the test. Shouldn't this be a good test?
Seeing that the ports are in 2 different vlans you are actually bridgeing the 2 vlans and is something can cause real problems,I'm not sure if spanning tree will take care of this if they are in 2 different vlans , maybe someone else can chime in , not a good situation if they connected to one another .
