6. About this Video What will we cover in the video ?
Building and Subnet Investigation Methodology
Calls vs Streams
TCP vs UDP
Wired vs Wireless
VPN and Split Tunneling
Inside vs Outside

7. Building and Subnet Methodology
Starting at an all up number and then determinging an area to investigate
Wifi, Transport, Egress, VPN, etc
Wired
Compare to other wired subnets.
Wifi
Comparing WiFi to other WiFi subnets in the same building (e.g. is it bad just for this subnet or is it affecting other subnets too? ) This helps refine the investigation to if it is the subnet or the egress having the issue.
Second Reflexive - how do I use this
This only useful for UDP.
Indicates egress or public facing IP space.

8. Demo 1

9. Areas of investigation
Audio Poor Calls Streams vs. Audio Poor Streams
Calls = overall experience
Stream = occurred on this subnet
TCP/UDP
Use the template report to look at Audio Stream Total for TCP
Identify subnets where TCP is in use. Draw distinction between if it is a subnet or if it is the egress point
Wired/Wireless
Wired
Lightweight story of common things to look at
Wireless
Band
Channel (no overlapping)
Drivers (last thing to look at)

10. Demo 2

11. VPN and External users VPN Inside/Outside Client based vs. site-based
VPN flag
Information on Split-Tunneling:
b00d c3-ec7eab5a8a43?ui=en-US&rs=en-US&ad=US
Inside/Outside
Once building data has been uploaded you can use some of the other filters to exclude External users, for example.
