I am reading this good document and essential for lab preperation: I saw this on page 41 and I wonder if it is a misprint.
page 41: "IEEE 802.11e, IEEE 802.1P, and DSCP Mapping WLAN data in a Unified Wireless network is tunneled via LWAPP (IP UDP packets). To maintain the QoS classification that has been applied to WLAN frames, a process of mapping classifications to and from DSCP to CoS is required. For example, when WMM classified traffic is sent by a WLAN client, it has an IEEE 802.1P classification in its frame. The AP needs to translate this classification into a DSCP value for the LWAPP packet carrying the frame to ensure that the packet is treated with the appropriate priority on its way to the WLC. A similar process needs to occur on the WLC for LWAPP packets going to the AP. A mechanism to classify traffic from non-WMM clients is also required, so that their LWAPP packets can also be given an appropriate DSCP classification by the AP and the WLC." This caught my eye: "traffic is sent by a WLAN client, it has an IEEE 802.1P classification in its frame" Am I going mad or should this not be 802.11e ? cause 801.1p is COS used on the wire vlan trunks. Right ?? your thoughts ? regards. Kristjan _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com
