Figure 139 WAN Summary Dashboard
The WAN summary dashboard page contains the following tables:
l Status : Displays the Link status and WAN Status for VLANs. For each VLAN, the green represents an up
status and red represents a down status for the Link and WAN.
l Throughput : Displays the In and Out traffic for VLANs. The Throughput table has four tabs for different
uplinks. First tab shows throughput of VLANs having high priority followed by other VLAN data based on its
priority. Clicking on each tab loads In and Out traffic throughput data for that particular VLAN.
l Latency :Displays Latency data for available VLANs.Each line represents one VLAN.
l Alerts : Lists the last five alerts with time stamp and description.
l Usage : Displays traffic based on Application Category or Application.
l Compression : Displays compression that occurred on all VLANs together.
Performance
The Performance page displays the performance details of the wireless clients and APs connected to the
controller.
Clients
This section displays the total number of wireless clients connected to the controller. You can view the
distribution of clients in different client health ranges, SNR ranges, associated data rate ranges, and data
transfer speed ranges using the histograms and distributed charts. You can click on the hyperlinked number to
view the data in different screens with histograms.
An AP’s client health is the efficiency at which that AP transmits downstream traffic to a particular client. This
value is determined by comparing the amount of time the AP spends transmitting data to a client to the
amount of time that would be required under ideal conditions, that is, at the maximum Rx rate supported by
client, with no data retries.
A client health metric of 100% means the actual airtime the AP spends transmitting data is equal to the ideal
amount of time required to send data to the client. A client health metric of 50% means the AP is taking twice
as long as is ideal, or is sending one extra transmission to that client for every packet. A metric of 25% means
the AP is taking four times longer than the ideal transmission time, or sending 3 extra transmissions to that
client for every packet.
