Cisco Catalyst Center Assurance Wi-Fi 6 Dashboard

Cisco Catalyst Center Assurance Wi-Fi 6 Dashboard


Note
We recommend you manage this feature using the Cisco Catalyst Center UI. The procedures are to be executed with for debugging purposes only.

The Cisco Catalyst Center Assurance Wi-Fi 6 Dashboard provides a visual representation of your wireless network. The dashboard contains various dashlets which show you the Wi-Fi 6 Readiness, and the efficiency of the Wi-Fi 6 networks compared to non-Wi-Fi 6 networks. For more information, see the Monitor Wi-Fi 6 Readiness section in the Cisco DNA Assurance User Guide.

  • Client Distribution by Capability: This dashlet shows all the clients associated and their capability in the wireless network. The inner circle shows the wireless protocol capabilities of all the different clients in the network. Capability here is the ability of wireless clients to associate with Wi-Fi 6 APs or non-Wi-fi 6 APs. The outer arc segment shows how many 802.11ax capable clients are joined to a Wi-Fi 6 network as well as how many of them are not.

  • Wi-Fi 6 Network Readiness: This dashlet shows all the APs in the network. The inner circle shows the APs which are Wi-Fi 6 APs and non Wi-Fi 6 APs. The outer arc segment shows the number of Wi-Fi 6 enabled AP in the network.

  • AP Distribution by Protocol: This dashlet shows the protocols enabled on your APs in real time.

  • Wireless Airtime Efficiency: This dashlet compares and displays the Airtime Efficiency between your Wi-Fi 6 network and Non-Wi-Fi 6 network for each of the access categories (voice, video, best effort, background).

    The spectrum is efficiently utilized if the AP’s radios can send more traffic (successful bytes transmitted to the client) in less airtime (microseconds) than other networks under similar RF conditions.

  • Wireless Latency by Client Count: This Dashlet compares the Wireless Latency between your Wi-Fi 6 and Non-Wi-Fi 6 Network for each of the access categories (voice, video, best effort, background).

    Wireless latency is measured by the time (microseconds) it takes for a packet to be successfully transmitted from an AP to the client. Hence, AP radios with a higher client count generally have higher latency than compared to those with a lower client count under similar RF conditions.


    Note
    Client count in this dashlet refers to the clients that are actively sending traffic for a given Access Category and are not just associated clients.

Configuring Wi-Fi 6 Parameters (CLI)

Procedure

Step 1

Enable subscription to Traffic Distribution by entering this command:

config network assurance subscribe ap-traffic-dist

Step 2

Configure Traffic distribution for AP-groups by entering this command:

config advanced wifi6 traffic-distribution {all | ap-group ap-grp-name } {enable | disable}

Note

 
The default AP group loses the configuration after the device is rebooted.

Note

 
When you execute the all option it will be applicable only for existing AP groups. Any new ap-group added after executing all option, the command needs to be executed for that ap-group separately or execute command with all option again.

Step 3

Configure the Traffic distribution statistics interval by entering this command:

config advanced wifi6 traffic-distribution {all | ap-group ap-grp-name } periodicity periodicity-secs

Step 4

View the status of the Traffic Distribution subscription by entering this command:

show network assurance subscription

Step 5

View the status of the Traffic Distribution by entering this command:

show advanced wifi6 ap-group default-group summary

Step 6

View the Traffic Distribution package statistics by entering this command:

test dsdump show traffic-distribution ap-mac slot-id package-type

  • Package Type 1: Packet count per MCS rate

  • Package Type 2: Byte Count, Air Time Used

  • Packet Type 3: Packet Count Per Latency Level (Good, Medium, High, Very High)

  • Package Type 4: Byte Count, Air Time Used

Step 7

View AP DFS counters by entering this command:

show ap auto-rf { 802.11a | 802.11b | 802.11-abgn } ap-name

Verifying Wi-Fi 6 Access Point Parameters (CLI)

Verifying Wi-Fi 6 Access Point Parameters in AP Console

Enter these commands in the AP console.

Procedure

  • To verify the traffic distribution statistics configuration, use the following command:

    show ap traffic distribution configuration

  • To verify the exported data from the AP to the controller, use the following command:

    show interfaces dot11Radio slot-id traffic distribution { cumulative | instantaneous | periodic} database

  • To verify Access Point DFS counters, use the following command:

    show interfaces dot11radio slot-id dfs

  • To debug the traffic distribution statistics, use the following command:

    { no} debug traffic wireless distribution dump { periodic | aggregated}

  • To clear the traffic distribution dump, use the following command:

    clear traffic distribution dump
