Re: Network sniffing tools that work with iSeries

[Kirk Goins <kgoins@xxxxxxxxxxx>]

Are you using Switches or Hubs? If it's switches sniffing takes extra 
steps. 

As you may know Hubs broadcast whatever comes in a port out ALL of the 
other ports on the hub.  With this config you can plug in a sniffer into 
any port on that hub and see any and all trafffic going thru it.

Switches on the other hand build internal tables of what device is 
attached to what port. When data from device A enters the switch the 
switch looks up the destination in the packet( device B ), finds device 
B in its internal table and only sends data out the "1" port where the 
device  B is connected. A sniffer plugged into any other port won't see 
the data.

To work around the above can be done a couple ways.
#1 On a lot of the Managed Switches you can set them up to allow an port 
to monitor traffic.
#2 Plug a Hub into the switch and then the sniffer and the device(s) you 
want to monitor into that hub.
