A company is deploying a WLAN for a new building. The wired network uses 802.1p CoS markings, but the wireless network will use WMM. The network team wants to ensure that wired CoS 5 (voice) traffic is mapped to the correct wireless priority when it reaches the WLC. What is the default mapping for CoS 5 to UP on a Cisco WLC?

A network engineer is configuring QoS for a WLAN that carries a mix of traffic. The engineer wants to ensure that traffic marked with DSCP CS6 (network control) is not placed in the highest WMM access category, because that category should be reserved for voice. What is the default UP mapping for DSCP CS6 on a Cisco WLC?
