We have a stack of 6, 48 port 3750 cisco switches and I would like to setup mirroring across the stack to send the data to a network analyser. I have done mirroring before on a single switch, but never on a stack of swtiches. My question is, what sort of things do I need to consider when trying to monitor a stack of c3750 switches with multiple vlans if I want to monitor all of the traffic on all VLANS with my network analyzer?
Since each switch is already stacked, do I only need to setup a single monitor port on one of the switches?
When I specify the port range that I want to monitor, should I just set the source port as being the various vlans I want to monitor, and then set the destination port as being a single port?
switch 1 provision ws-c3750-48ts switch 2 provision ws-c3750-48ts switch 3 provision ws-c3750-48ts switch 4 provision ws-c3750-48ts switch 5 provision ws-c3750-48p switch 6 provision ws-c3750-48p
Sorry for asking multiple questions in a single post, I can break it up if needed - it just seems like all of the questions are a part of the overall question regarding configuring SPAN across a switch stack.
