How to configure the mask of an ACL on a WLAN device

For WLAN devices, masks (wildcards) must be specified for the source and destination IP addresses in ACL rules.

The wildcard is in dotted decimal notation. In a binary wildcard, the value 0 indicates that this bit needs to be matched and the value 1 indicates that this bit does not need to be matched. 0s and 1s in a wildcard can be discontinuous.

For example, the IP address 192.168.1.169 and the wildcard 0.0.0.172 represent address 192.168.1.x0x0xx01. x can be 0 or 1.
