  • 1.  WiNG 7.6.3 Options for viewing client channel capabilities

    Posted 01-24-2022 16:36
    Pretty sure in XIQ you can see the end clients capabilities, including what channels they can do. Is this possible anywhere in WiNG 7.6.3 using Wing Man or Nova GUI or even CLI?

    Best I can find is show wireless client detail "MAC address". And lists about everything but channels.

    Would like to use DFS channels, but would like to know current client capabilities.

    Hello Josh,
           There is no method on WiNG to identify the wireless client channels that are supported. You are correct regarding the "show wireless client detail", it shows the wireless client capabilities, except the channels the wireless client supports. 

    You should be able to obtain the specifications sheet for any wireless client from the vendor, which would illustrate the wireless client supported channels. 

    Most 5GHz wireless clients today support the following channels:

    36,40,44,48,140,149,153,157,161,165 (I have probably seen only 2 devices that don't support channel 165). 

    You can take a wireless capture from an AP, prior to when the wireless client associates to the AP, and after the wireless client associates successfully, the wireless capture will have the channel capabilities available. 

    From AP CLI:

    service pktcap on radio 2 count 200 write tftp://xxx.xxx.xxx.xxx/wirelessclient.pcap filter ether host yy-yy-yy-yy-yy-yy (x represents TFTP server IP and y represents the wireless client mac address)

    You can view the pcap file via Wireshark (freeware) and review the wireless client association request during the association process. Under the association request, expand IEEE 802.11 Wireless Management/Tagged parameters and expand Tag: Supported Channels

    You should see something similar to the following:

    Hope this helps.
