Correcting a WAN Subsystem Process Configuration Problem
If a ConMgr process, TFTP server process, WANBoot process, or SNMP trap
multiplexer process has not been added or is not configured correctly, you must add or
modify it.
ConMgr Process
To add a ConMgr process, see the WAN Subsystem Configuration and Management
Manual.
You can only modify the executable object code file name (IOPOBJECT attribute) for
the ConMgr process by using the SCF ALTER PROCESS command:
ALTER PROCESS $ZZWAN.#cpu-num,
IOPOBJECT object-file
Verifying a WAN Subsystem Device
Configuration
This section describes the SCF commands used to determine if a WAN subsystem
device (DEVICE object) is configured correctly.
1. Determine the location of a WAN subsystem IOP by using the SCF INFO DEVICE
command:
INFO DEVICE $ZZWAN.#*
Determining the Location of a WAN Subsystem Device on page A-4 shows the
output of this command and explains how to interpret that output.
Note. You must use the SCF STOP PROCESS command to stop a WAN subsystem process
before altering it. You must use the SCF START PROCESS command to start a WAN
subsystem process after adding or altering it.
Note. If a device is a line-handler process (also referred to as a WAN subsystem IOP), the
primary and backup processes should be configured in the same processors as the preferred
and alternate TCP/IP processes that support the SWAN concentrator; for example, in
processors 0 and 1 or in processors 2 and 3. This is required to achieve optimum performance.
Note. If you do not know where the preferred and alternate TCP/IP processes are
configured, see Identifying the WAN Subsystem Processes and Objects
on page 3-6.
Note. Depending on which TCP/IP product you are using, for more information, see one
of these manuals:
