[cisco-voip] how to take wireshark trace between two routers.

[Norton, Mike]

Anand,

If you are new to configuring SPAN ports then I suggest starting with this article which turned up at the top of some quick Googlage:

Catalyst Switched Port Analyzer (SPAN) Configuration Example
http://www.cisco.com/en/US/products/hw/switches/ps708/products_tech_note09186a008015c612.shtml

Also please note that I did not indicate a willingness to take this discussion off-list. I'm re-adding the list to this thread, please keep it that way.

Hi Mike ,

I have connected the two routers with a cross cable on their ethernet interfaces.

You will need to get your Wireshark machine connected in between the two routers somehow. Since you didn't give any information about how the two routers are connected to each other, I can only offer guesses on how you might accomplish that. If they are connected straight to each other with Ethernet, then put a hub (or a switch with a SPAN port) in between or use an Ethernet tap. If they are connected to each other with something other than direct Ethernet, then I'm guessing you're SOL but at the very least you would need to provide us with information about the connection.

Hi

I have two routers .On 1 router i have router---switch--phone(1000)

second router   router----phone(3000)

i want take wireshark trace.I was able to take the trace when i called from 1000-3000 by connecting the pc to the switch.

In wireshark i can see information happening on first router but i cannot see any information about second router nor the phone.

My question is how to see the packets between the routers using wireshark trace.

thanks,
anand.
