Summary

Question

How are traffic parameters being calculated in vSZ?
Client traffic in vSZ/SZ
Total AP traffic (uplink/downlink)
WLAN traffic

Customer Environment

Resolution

The Traffic information on the AP Zone/WLAN shows the data utilized along with the historical and real time data.
Users can check the total amount of Traffic uplink and Traffic downlink traffic of connected clients, WLAN and AP pages respectively.



A drop-down selector at the top of the series of charts determines the reporting type:
1.    Historical  – this is a histogram of past reported data, based on the normal reporting interval of the system (e.g. 5 minutes)

When selected, there should also be a drop-down selector for time interval of the histograms. Time interval should support 1hr, 24hr.
When selected, there should also be a WLAN selector that allows either a specific WLAN to be selected, or all WLANs to be selected.



2.    Real-Time – this is a real-time display based on a live stat subscription to the AP:
When selected, there should be a WLAN selector which shows the WLAN specific or all WLANs.



Traffic real time chart can further be modified based on the Bytes, Packets and Rates:
Selecting “start” shows the real time traffic.

There are 5 total data displays, which are defined below.
1.    Historical Traffic – measures the total amount of traffic sent or received by the AP
a.    Chart Title: Traffic
b.    Drop-down Option for Charts

i.    Radio
1.    Total – if selected, report aggregate of both radios
2.    2.4 GHz – if selected, report only 2.4 GHz data
3.    5 GHz – if selected, report only 5 GHz data



ii.    Metric:
1.    Bytes
2.    Packets
3.    Rates



iii.    Direction
1.    Rx and Tx (Total uplink + Downlink)
2.    Tx - Downlink (from AP to client)
3.    Rx - Uplink (from client to AP)



c.    Chart Type: Line graph
d.    X-axis: Time
e.    Y-axis: Auto-adjust from Kbps, Mbps, Gbps
f.    Hover behavior: show 3 data points: total (aggregate of tx and rx for selected radio bands), tx, and rx for that time coordinate and radio band.

> The client tab below the traffic shows chart form of the number of clients connected along with the radio band info and the time frame:


> Second client tab in the traffic info shows the TOP clients and data utilized along with the OS info of all the clients in the Zone. Also, it shows the application details:
a.    When the administrator hovers:
i.    Client – show following data with labels
1.    Downlink – sent to client
2.    Uplink – received from client
3.    Total – total of uplink/downlink

ii.    OS / Device Type – show total device count for this OS type and % of selected scope (time and WLAN)
1.    Devices – count of devices over this time period
2.    % – percentage of all clients that match this OS type

iii.    Application – show total uplink bytes for application, downlink for application, and total of uplink/downlink
1.    Downlink – sent to client by this app
2.    Uplink – received from client by this app
3.    Total – total of uplink/downlink

b.    When the administrator clicks
i.    Client – do nothing
ii.    OS / Device Type – do nothing
iii.    Application – do nothing




 

Note: The timeframe is limited to 1 hour to 24 hours in the controller. We cannot view the info more than 24 hour in the traffic tab.
