I wonder if someone can please help.
A customer has two Layer2 switch's trunked to each other, and is requesting what conversations are flowing between the two switches. There is a total of 10 Vlans on each switch. They need a permanent setup to check the dataflow. We don't really want to leave a sniffer running on one of the switch's SPANning the Trunk port. Is there another way we can see source/destination IPs such as VACL's. One of the switches is a 4948.
