1. Connection via SSH
Check the SSID with the following commands:
Router> _debug wireless_dbg iwconfig
Router> debug system brctl show
Assume the station is connecting to the SSID "Kuestriner VH" , we can see this SSID is "wlan-2-2", which the interface is "localbr0".
If the SSID is "wlan2-1", the interface is "br0".
2. Check Station
Check if the station is connected.
Router> show wlan slot1 list all sta --------for 2.4G clients
Router> show wlan slot2 list all sta ---------for 5G clients
3. Packet Trace
Confirm that the AP receives the packets from the station. Perform a ping to 184.108.40.206 from the station. You can see the packet flow displayed like the following.
Router> packet-trace interface localbr20
