RAS Server and Port Administration
The RAS server administration functions enable you to get information about a
specified RAS server and its ports. These functions also enable you to
terminate a connection on a specified RAS server port.
The
RasAdminServerGetInfo function returns a
RAS_SERVER_0 structure that contains information about the configuration of a RAS server.
The returned information includes the number of ports currently available for
connection, the number of ports currently in use, and the server version number.
The
RasAdminPortEnum function retrieves an array of
RAS_PORT_0 structures that contains information for each of the ports configured on a
RAS server. The information for each port includes:
- The name of the port
- Information about the device attached to the port
- Whether the RAS server associated with the port is a Windows NT Server
- Whether the port is currently in use, and if it is, information about the
connection
You can call the
RasAdminPortGetInfo function to get additional information about a specified port on a RAS
server. This function returns a
RAS_PORT_1 structure that contains a
RAS_PORT_0 structure and additional information about the current state of the port. The
RasAdminPortGetInfo function also returns an array of
RAS_PARAMETERS structures that describe the values of any media-specific keys associated
with the port. A
RAS_PARAMETERS structure uses a value from the
RAS_PARAMS_FORMAT enumeration to indicate the format of the value for each media-specific key.
The
RasAdminPortGetInfo function also returns a
RAS_PORT_STATISTICS structure that contains various statistic counters for the current
connection, if any, on the port. For a port that is part of a multilink connection,
RasAdminPortGetInfo returns statistics for the individual port and cumulative statistics for all
ports involved in the connection. You can use the
RasAdminPortClearStatistics function to reset the statistic counters for the port. The
RasAdminPortDisconnect function disconnects a port that is in use.
Use the
RasAdminFreeBuffer function to free memory allocated by the
RasAdminPortEnum and
RasAdminPortGetInfo functions. Use the
RasAdminGetErrorString function to get a string that describes a RAS error code returned by one of
the RAS server administration (RasAdmin) functions.
