I am monitoring one of my VLANs. I use a reflector port to an RSPAN VLAN. The switch is a 3550. When I analyze the resutlts in my sniffer, I notice I am getting both RX/TX for the port in question.
The port has an IP phone connected to it. I dial from a PSTN line in to that phone, and the sniffer shows the 2 way conversation, when I expected to only see the PSTN side (RX) of the conversation. But as I mentioned, I see TX and RX. Why is that? Quite frankly, I prefer RX/TX, but this makes no sense.
Sample of my config:
My sniffer is connected to port fa0/47 on the dest switch. Nothing is connected to Fa0/24 on the monitored switch
The actual SPAN traffic is carried by the physical port and not the Etherchannel? ON the second switch, do I configure the source as port 23 or should it be ?monitor session 1 source interface port-channel 1"?
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
