rules depending on AP status. This process is called priority mapping. The set of QoS priority
parameters decides the scheduling priority and forwarding priority of the packet.
Priority mapping is implemented with priority mapping tables and involves priorities such as 802.11e
priority and 802.1p priority.
Introduction to Priority Mapping Tables
The AP provides various types of priority mapping table, as listed below.
z dot11e-lp: 802.11e-to-local priority mapping table.
z dot1p-lp: 802.1p-to-local priority mapping table.
z dscp-lp: DSCP-to-local priority mapping table, which applies to only IP packets.
z lp-dot11e: Local-to-802.11e priority mapping table.
z lp-dot1p: Local-to-802.1p priority mapping table.
z lp-dscp: Local-to-DSCP priority mapping table.
Table 7-4 through Table 7-7 list the default priority mapping tables.
