You would get the feature on the first HP managed switch, but you may expect packet loss quickly.
If you can plug between the core switch and the other, then you could buy a TAP.
What sort of troubleshooting are you looking for ?

I'm not sure how much traffic is on the Switch. (-; That's why I'd like to take a peak inside and see what's flying around in there. I have some 10Meg Hubs, though Thought it should not be to much overhead to copy the packet to a 2nd port if Hubs can do it to all Ports. I know its not built the same, though ....
What I usually end up doing is Putting the Hub at the Uplink port on the Switch where it goes to the next mainstream switch, or router. SO in the case of finding out who is hogging our internet connection I put the Hub between the firewall and the Core LAN Switch. So I get any packets in and out of the firewall to the local LAN. We looking for a more 'efficient' solution.
So no Low end switches that can do this?
Thanks,

mirroring port or monitor port (the same) copy packet from/to a port to another. While that sound great in debugging, that overload the switch. I already saw Cisco 3550 starting to loose packet when activating the mirroring, just for a port with 10Mb/s.
For 16 ports, your may just use a hub ;)
How much traffic in total through all these 16 ports do you expect ?
TAP are great for this activity, but i think it's limited to one cable at a time

"Scott Townsend" <scooter133@xxxxxxxxxxxxxxxx> wrote in message news:umQSvVqBIHA.5868@xxxxxxxxxxxxxxxxxxxxxxxI'm looking for a switch I can use for helping with network troubleshooting. One that has one port on it that will see all of the Packets on the switch regardless of the port the packet is destined for. I think its called a Mirror or RMON port?? I would need at least 16 ports.
Any recommendations?
Thanks,
