Monitoring CAt 4006

I have been asked to run a network scanner/sniffer on our switch to see what the traffic is like. I know that spanning needs to be set in order for one port to see all of the traffic of the switch. I have looked and saw how to configure to scan one port. Is there an easy way to monitor all of the ports to see what the traffic is like? What would the commands be? Thanks in advance.

Hi, I configured this way, because I use vlans.

set span 65,71-76,82-86 3/11 both inpkts disable learning enable create

For ports you can use :

set span

for example : set span 3/1-30 3/45

bye,

Paulo

Hi, you can even use

set span

Example set span 1,2,3 3/44

But be carefull, many span sources could overload your Cat4000 CPU and you also would loose frames when the mirrored traffic exceeds the destination port bandwith.
