2950 port monitoring - can I turn off VLAN tagging?
On a 2950 switch, when monitoring an access port via another access port all packets are getting VLAN tagged. While SnifferPro understands this, LANwatch and our other packet sniffing tools don't. They see Ethernet frame type 8100 [VLAN tagged frames] but cannot decode the packets.
Can I not have frames VLAN tagged while monitoring?

I asked TAC about this a few weeks ago and was told that a future IOS release would either reverse this behavior or at least provide a command that will do so. It does indeed occur whether or not the port is a trunk, and I'm somewhat at a loss as to the logic behind this.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
