MSS displays IP addresses in dotted decimal notation — for example, 
192.168.1.111. MSS makes use of both subnet masks and wildcard 
masks. 

Unless otherwise noted, use classless interdomain routing (CIDR) format 
to express subnet masks — for example, 192.168.1.112/24. You indicate 
the subnet mask with a forward slash (/) and specify the number of bits in 
the mask. 

Security access control lists (ACLs) use source and destination IP addresses 
and wildcard masks to determine whether the wireless LAN switch filters 
or forwards IP packets. Matching packets are either permitted or denied 
network access. The 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. You specify the wildcard mask in dotted decimal 
notation. 

For example, the address 10.0.0.0 and mask 0.255.255.255 match all IP 
addresses that begin with 10 in the first octet.

Name “globbing” is a way of using a wildcard pattern to expand a single 
element into a list of elements that match the pattern. MSS accepts user 
globs, MAC address globs, and VLAN globs. The order in which globs 
appear in the configuration is important, because once a glob is matched, 
processing stops on the list of globs.

A user glob is shorthand method for matching an authentication, 
authorization, and accounting (AAA) command to either a single user or 
a set of users. 

A user glob can be up to 80 characters long and cannot contain spaces or 
tabs. The double-asterisk (**) wildcard characters with no delimiter 
characters match all usernames. The single-asterisk (*) wildcard character 
matches any number of characters up to, but not including, a delimiter 
character in the glob. Valid user glob delimiter characters are the at (@) 
sign and the period (.).
