I don't want to cause undue stress on the network, I would just like
to have the flexibility to monitor hosts on my network without having
to configure it every time. So instead, say I want to monitor a
specific host. How would I go about setting up monitoring in this
scenario:
[Wireshark]--Fa0/24--[SWITCH1]--Gi0/1--[SWITCH2]--Fa0/12-[TARGETHOST]
Thanks!
