Hi,


If you set private Vlans on 3750 and 2950 does not support it, then hosts in the same vlan will be able to communicate with each other throught 2950 switch (layer 2 traffic).

If you want to create a fully private vlan topology then you need to configure it on both 3750 and 2950 switch (upgreat IOS to one that supports pvlan).


Hope that expalains why, if yes, please rate it.

2950 - use protected port?
