Hello, I just want to know if Wireshark only collects information of client and server right? in between client and server there are many network components/elements. do we see that information also? for e.g. in wireshark log I see server is sending slow data but is it possible some router(or any network element in between client and server)may be slow?

Thanks, Manju

Wireshark can show you whatever happens on the "network segment" you capture on.

What "network segment" entails is a varying matter. For instance if you capture on an endpoint with an uplink to a switch you'll see the host traffic (to/from), broadcast traffic, multicast traffic for groups the endpoint has joined (in case of a multicast aware switch) and link-local traffic like IPv6 NDP, spanning tree and maybe switch specific traffic. But if the capture is taken from a monitor port it may be vastly different. Either you see all ingress and egress traffic of a collection of ports, or from a vlan, either with or without tags. Doing a capture on a switch or router uplink may show even other traffic, like OSPF, IS-IS, RIP or whatever.

So, bottom line is it all depends on the point you capture at.
