Warning
Warning. In DSM interfaces, a condition encountered in performing a command or other
operation, that can be significant but does not cause the command or operation to fail.
A warning is less serious than an error. Compare error.
well-known port. Any of a set of protocol ports preassigned for specific uses by transport
level protocols (that is, TCP and UDP). Servers follow the well-known port assignments
so clients can locate them. Examples of well-known port numbers include ports
assigned to echo servers, time servers, remote login (TELNET) servers, and file
transfer (FTP) servers.
wide area network (WAN). A network that operates over a larger geographical area than a
local area network (LAN)—typically, an area with a radius greater than one kilometer.
The elements of a WAN may be separated by distances great enough to require
telephone communications. Contrast with local area network (LAN).
wide area network (WAN) subsystem. The Subsystem Control Facility (SCF) subsystem
for configuration and management of WAN objects in G-series RVUs.
wild-card character. A character that stands for any possible character(s) in a search string
or in a name applying to multiple objects. In DSM object-name templates, two wild-card
characters can appear: question mark (?) for a single character and asterisk (*) for
zero, one, or more consecutive characters. See also object-name template.
X.25. The CCITT standard protocol for transport-level network service. Originally designed
to connect terminals to computers, X.25 provides a reliable stream transmission
service that can support remote login.
X.25AM. See X.25 Access Method (X.25AM).
X.25 Access Method (X.25AM). An HP product that implements, for WANs, the services of
the Network Layer and layers below.
X.25 network. Any network or subnetwork linked using X.25 standards. X.25 standards are
CCITT standards that define packet switching carrier communication in the Network
Layer over wide area networks (WANs). See also International Telecommunications
Union Telecommunications (ITU-T) and packet switching.
$ZZLAN. See LAN manager (LANMAN) process.
$ZZWAN. See WAN manager process.
