I have a virtual server and I'd like to capture traffic going to that virtual server. How do I span the port on my Cisco switch. I am not onsite so I do not know the port where the physical server is connected to. Any ideas? Thx

Do you have access to the server, for example, like RDP?

If you can, then you can install wireshark and capture the traffic, otherwise you need to find a switchport where the vm host is connected.  In that case, you will be capturing all the traffic going to the vm host.

Is it possible to capture the port where the virtual server is connected to? I am not sure how that will work?

You need to find the MAC address of the physical server and then look at the mac address table.

However, how/where are you going to SPAN the traffic if you don't have physical access to the switch?

Just to make sure if you do span the port you will capture ALL traffic to that physical server, not just the traffic to that VM.

This is what I have:
- I can access the switch
- I know the MAC and IP address of the physical server where the virtual server resides.
- I know the switch port where the physical server is connected to.
- I know the MAC address of the virtual server.

I just want to capture the traffic to the virtual server, not the whole physical server. It has to have a way to do this. Thx

Span session only know ports.  So all traffic going in/out of the port is mirrored.

If you have the correct access to the ESXi host you can capture traffic there using TCPDUMP.

I will just capture the port where the physical server is connected to and setup the filter on the virtual server. Thx
