I have a question about setting up a SPAN session:
We have a banking ATM that needs to have all transaction data superimposed on the DVM monitoring images.
Accroding to the ATM people:
"The DVR device needs to be deployed onto a mirror port of the ATM. In this manner as the ATM transaction is mirrored onto the DVR port the message stream can be parsed for the transaction data so that it may be superimposed onto the DVR image."
My understanding of this is that it would be a simple monitor session configured to monitor the ATM port and mirror it onto the destination port, which is where the DVM equipment will be plugged into the switch.
If that is that case, can I still communicate with the DVM equipment if it is plugged into a mirror port?
Is the session destination port still active on the network like any other port, just has the data from both ports on it?
The link to the router is trunking two vlans on the switch, not sure if that makes a difference.
