A customer has dual-band devices that they want to use 40 MHz channels. If the customer is using Cisco 3600 Series access points with a 5508 controller. Which setting assists with this change?
A. Enable band select globally.
B. Enable aggressive load balancing.
C. Disable lower data rates on 802 .11G GHz radios.
D. Disable overlapping 802.11G channels.
A is correct
Although this feature is designed to help 802.11n capable dual band clients to select the 5Ghz band (and utilize the bonded/40MHz wide channels on the 5Ghz frequencies), it has to be used with caution on voice enabled WLANs (with time-sensitive voice clients) as it can cause roaming delays or dropped calls. Please make sure you test it thoroughly in your environment with the dual band clients before enabling it.
