I'm doing exactly that. I have two 5509s spanning into a smaller switch, and the smaller switch spanning into my sensor. But we're moving in a few months, and after the move, I'll be trunking the 5509s, so I won't need to do that anymore.

Williams Sent: Wednesday, June 19, 2002 10:20 PM To: [EMAIL PROTECTED] Subject: Multi-Switch SPAN/Monitor question [7:47026] Okay....... Let's say I have three switches (or four or whatever)..... assume these switches are capable of SPANning/Monitoring *all* of the traffic on the switch to a single port..... (assume the bandwidth required for the span port isn't more than the bandwidth of the port, which for this discussion is 100Mbps). So, now I have 3 switches , each of which are sending all of their traffic out of a span port. Is it possible to take each of those 100Mbps span links, then connect them into another switch (say a 3550 or something that takes 100Mbps ports and has Gig out) and span them out on a single link? Since a 3550 can span all traffic in a VLAN (which would be all traffic coming into the switch by default) to a port, could I use that 3550 so combine all of the data coming in across all 3 of those 100Mbps span ports from the other switches and combine them and span them out of a gig port on the 3550? Reason I ask, is that we were trying to think of a way to "span" all of the traffic across multiple switches into a single line to connection to an IDS sensor...... Anyone ever do this? Any of your security/IDS people every do this? TIA, Mike W.
