I am trying to use Wireshark to resolve a QoS issue. We have
a polycom video conference camera on our site that is setting up a session with
a remote polycom. Our ISP says they are not seeing any packets marked appropriately.
Their evidence is NETFLOW reports collected from their edge router located on
campus.
Should I be able to set up a remote span session (all Cisco
hardware) and see the QoS in the packet’s Differentiated Services Field?
My monitor session look something like this:
Switch 1 (site with our Polycom)
Monitor sess 1 source inter fast x/x both
Monitor sess 1 dest remote vlan 400
Switch 2 (my office)
Monitor sess 1 source remote vlan 400
Monitor sess 1 dest inter fast x/x
I have been looking for a sample QoS trace just to see what
it would look like but could not find one.
Thanks.
