Perform the following functions on this tab:
Egress COS
Use the Egress COS tab (Figure 85) to modify the default priorities assigned to 802.11 packets
leaving the AP by creating a COS-to-TCID mapping.
If a TCID-to-COS mapping is defined, the TCID value is obtained from the mapping table of the
interface based on the COS field of the frame. By default, COS-to-TCID mapping is one-to-one,
i.e. COS 0 maps TCID 0, 1 maps to 1 … and 7 maps to 7. If your network supports fewer than 8
priority levels, you can map multiple COS levels to a single TCID value.
