A customer has noticed that Client Band Select is enabled and no clients are utilizing the 5 GHz band. Which three parameters must be met to ensure that wireless clients use the 5 GHz band? (Choose three.)
A.
Ensure that channel bonding is enabled on the WLAN.
B.
Ensure that the co-channel interference has not exceeded גˆ’85 dBm.
C.
Ensure that the UNII-2 extended channels are enabled on the 802.11a radios.
D.
Ensure that the client is receiving RSSI above the minimum band select RSSI threshold.
Ensure that the UNII-2 extended channels are enabled on the 802.11a radios.
i thought the radios need to be active for this to be put in place? and if so F is already in the mix with C so CDE should still stand? or if it a case of you enable the channels but not necessarily enable the radio.
thanks in advance
Many clients do not support the UNII-2 Extended channels due to the DFS requirements, and thus the client manufacturer not wanting to spend the money to match the requirements of operating in that space, so it is definitely not one of the answers, in fact if you were having clients not joining the 5.0GHz with Band-Select enabled you would want to ensure UNII-2 channels are disabled.
