Chapter 7 Configuring QoS on an Access Point
Configuration Guidelines
Ethernet Interface Transmit Queue
Since the Ethernet interface always has a larger bandwidth than radio interface, there is no need to maintain priority queues for Ethernet interface. There will be only one transmit queue per Ethernet interface.
802.1Q Untagged Voice Packets
If VLAN is enabled, IOS bridging code adds 802.11q tags into the untagged voice packets. The class of service (CoS) value should be part of the VLAN configuration. For a voice VLAN, the CoS should be
(6).
If VLAN is not enabled, the access point relies on the
QoS on VLAN
The default cos value for all the VLANs is zero (best effort). This ensures that the access point provides differentiate services based on VLAN IDs. Packets sends to these clients are queued into the appropriate priority queue based on their VLAN CoS value.
If VLAN is enabled, packets from a wireless client that must be forwarded to the wired network, a 802.1q tag is added by the forwarding module.
