Q1. How does the WLC queue packets ingress and egress? FIFO? Any documentation?
Q5. If the AP is not configured for WMM, what queuing does it use? WMM uses EDCF right?
Q6. All four WMM queues seem like Strict Priority queues, where each queue will be fully served before a lower priority queue?
Answered:
Q2. How does the AP assign a packet to the Queue? based on 802.1p? Or any packet on the WLAN with Platinum profile will be put into Voice queue irrespective of the 802.1p?
>>1st, 802.1p is ignored from SW-->WLC, only DSCP mapped
Q3. Leading from Q2 - Does the WLC or AP remark QoS of traffic from the Switch or User according to the QoS Profile?
eg. packet with 802.1p=0 comes into WLC from the switch on a VLAN with Platinum Profile, does it get changed to 802.1p=5
>>yes, but only if it is greater
Q4. Documents say that with QoS Profiles applied to a WLAN, the AP may remark the LWAPP CoS value if the 802.1p value is higher than the Profile. Leaves the encapsulated DSCP the same yes?
>>yes DSCP stays same, it is only a ceiling for 802.1p/e
