Re: Reccomend a Switch for Network troubleshooting?

Hello,

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

I'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,
Scott<-
