Discussing the User Interface System
The software (Multiprotocol Routing Services) is a multitasking system that
schedules use of the CPU among various processes and hardware devices. The
router software:
vProvides timing and memory management, and supports both local and remote
operator consoles from which you can view and modify the router’s operational
parameters.
vConsists of functional modules that include various user interface processes, all
network interface drivers, and all protocol forwarders purchased with the router.
Understanding the First-Level User Interface
The user interface to the software consists of the main menu (process) and several
subsidiary menus (processes). These menus are related to the multiple levels of
processes in the software.
The first level of processes consists of the OPCON and CONFIG-ONLYprocesses.
In most cases, you will use the OPCON process to access the second level to
configure or operate the base services, features, interfaces, and protocols you will
run on your IBM 2210.
The second level of processes consists of the processes listed by the status
command. Youuse the talk
pid
command to access the second-level processes.
There are processes that you cannot use in the software. See Table1 on page 10
for an overview of the processes.
Figure 1shows the processes and how they fit within the structure of the router
software.
