Wildcard Masks; Class Of Service - D-Link DWS-1008 - AirPremier MobileLAN Switch Product Manual

When you specify source and destination IP addresses in an ACE, you must also include a mask for
each in the form source-ip-addr mask and destination-ip-addr mask.
The mask is a wildcard mask. The security ACL checks the bits in IP addresses that correspond to any
0s (zeros) in the mask, but does not check the bits that correspond to 1s (ones) in the mask. Specify
the IP address and wildcard mask in dotted decimal notation. For example, the IP address and wildcard
mask 10.0.0.0 and 0.255.255.255 match all IP addresses that begin with 10 in the first octet.
Class-of-service (CoS) assignment determines the priority treatment of packets transmitted by a switch,
corresponding to a forwarding queue on the AP.
The table below shows the results of CoS priorities you assign in security ACLs.
AP forwarding prioritization occurs automatically for Wi-Fi Multimedia (WMM) traffic. You do not need to
configure ACLs to provide WMM prioritization. For non-WMM devices, you can provide AP forwarding
prioritization by configuring ACLs.
If you disable WMM, AP forwarding prioritization is optimized for SpectraLink Voice Priority (SVP)
instead of WMM, and the AP does not tag packets it sends to the switch. Otherwise, the classification
and tagging described in "Displaying QoS Information".
If you plan to use SVP or another non-WMM type of prioritization, you must configure ACLs to tag the
packets.
Optionally, for WMM or non-WMM traffic, you can use ACLs to change the priority of traffic sent to an
AP or VLAN. (To change CoS for WMM or non-WMM traffic, see "Using ACLs to Change CoS".)
