4. If the file does not exist in any of these subvolumes, an error is generated and the
WAN manager process does not exit.
5. If the file was located in one of the subvolumes, the WAN manager process
configures the object with the file resolved and saves the resolved subvolume in
the system CONFIG database.
The WAN manager process applies this algorithm while accepting SCF ADD and
ALTER commands and during the coldload of the system (and restart of WANMGR).
This method ensures that the files are taken from the current SYSnn/CSSnn or
SYSTEM subvolumes.
These files cannot reside on a system other than the system where the WANMgr
process, $ZZWAN, is running. WANMgr returns the error, WAN 00049, when
configuring a concentrator, device, process, and profile or a task using remote files.The
error is also returned when changing the configuration for a concentrator, device, or
process using remote files. WANMgr no longer stores system names in the CONFIG
file for these attributes.
WAN Subsystem SCF Interface
You make changes to the initial WAN subsystem configuration online using the SCF
interface to the WAN subsystem. The WAN subsystem SCF interface is provided to
configure, control, and display information about configured objects within the WAN
subsystem.
When you use SCF to add or alter WAN subsystem objects, the changes take effect as
soon as the object is started. These changes persist through system processor
reloads; they also persist through system loads, unless you load the system with a
different configuration file.
Table 3-2 briefly describes the WAN subsystem objects on which the WAN subsystem
SCF command operate. For more information about the WAN subsystem SCF
commands, see Section 6, SCF Commands.
Table 3-2. WAN Subsystem Objects (page 1 of 2)
Object Description
ADAPTER Represents the SWAN concentrator.
DEVICE Represents a data communications subsystem object that uses a line
on the SWAN concentrator.
PATH Defines an Ethernet path on a CLIP by defining an IP address to each
Ethernet port interface (SCC1 and SCC2) on each CLIP on the SWAN
concentrator.
PROCESS Represents the Concentrator Manager (ConMgr) process, the SNMP
trap multiplexer process, the TFTP server process, and the WANBoot
process.
PROFILE Defines configuration modifiers that are used by the data
communications subsystem objects.
