Hello,
Switch Model - PowerConnect 5424
SW version - 2.0.0.46
I have a problem with BPDU Filtering (Spanning-Tree)
this is my topology (attached picture), both switches working fine with STP - MST
(CISCO Switch is the - root bridge for instance 1 + 2).
-----------------------------------------
My problem appear when i connect new switch to Dell PowerConnect 5424 that is working with PVST, but the connection port configured with STP DISABLE + global configuration (spanning-tree bpdu filtering).
In this situation the Dell Switch become the root bridge for instance 1 + 2.
What can i do to block bpdu message (PVST) from the new Switch that connect to dell and working with PVST. (Attached example),
Thanks,
