30CHAPTER 1: USING THE COMMAND-LINE INTERFACE

Wildcard Masks Security access control lists (ACLs) use source and destination IP addresses and wildcard masks to determine whether the WX 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.

The ACL mask must be a contiguous set of zeroes starting from the first bit. For example, 0.255.255.255, 0.0.255.255, and 0.0.0.255 are valid ACL masks. However, 0.255.0.255 is not a valid ACL mask.

User Globs, MAC Name “globbing” is a way of using a wildcard pattern to expand a single Address Globs, and element into a list of elements that match the pattern. MSS accepts user

VLAN Globs 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

User 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 (.).

For example, in Table 3, the following globs identify the following users:
