Hi all,

I'm trying to deploy a Snort box in my LAN. I have a Linksys SRW248G4 and trying to configure Port mirroring so that Snort can listen everything on the network in promiscuous mode.

So in ADMIN / Port Mirroring, I have 3 things:

Source Port (e1,...e48, g1...g4)
Type (Rx, Tx, Both)
Target (e1...e48, g1...g4)

Last time I played with it, I killed all traffic on the switch, I had to reboot it several times... so now I'm asking question before:

Do I need to configure each Source Port (from 1 to 48) to forward to the single promiscuous port ? 48 rules !? Is that correct ?

Thanks !

We have a database in which all the PKs are GUIDs, and most of the PKs are also the clustered index for the table. We know that this is bad (due to the random nature of GUIDs).
