user glob
A D-Link convention for matching fully qualied structured usernames or sets of usernames
during authentication by means of known characters plus two special “wildcard” characters.
Double asterisks (**) represent all usernames. A single asterisk (*) can appear either before
or after the delimiter in a user glob and can represent any number of characters up to the next
delimiter. A delimiter can be an at (@) sign or a dot (.). See also MAC address glob; VLAN
glob.
user group
A collection of users with the same authorization attributes.
vendor-specic attribute
See VSA.
virtual LAN
See VLAN.
VLAN
Virtual LAN. A set of ports that share a single Layer 2 network. Because the ports that constitute
a VLAN can be on a single network device or multiple devices, VLANs enable you to partition
a physical network into logical networks that meet the needs of your organization. You can
divide a single device into multiple logical Layer 2 switches, with each VLAN operating as a
separate switch, or make multiple devices members of multiple logical Layer 2 networks. By
default, all DWS-1008 switch ports are members of VLAN 1, which is named default.
VLAN glob
A D-Link convention for applying the authentication, authorization, and accounting (AAA)
attributes in the location policy on a switch to one or more users, based on a virtual LAN
(VLAN) attribute. To specify all VLANs, use the double-asterisk (**) wildcard characters. To
match any number of characters up to, but not including a delimiter character in the glob, use
the single-asterisk wildcard. Valid VLAN glob delimiter characters are the at (@) sign and the
dot (.). See also location policy; MAC address glob; user glob.
Voice over IP
See VoIP.
VoIP
Voice over IP. The ability of an IP network to carry telephone voice signals as IP packets in
compliance with International Telecommunications Union Telecommunication Standardization
Sector (ITU-T) specication H.323. VoIP enables a router to transmit telephone calls and
faxes over the Internet with no loss in functionality, reliability, or voice quality.
