gateway that contains a more comprehensive routing table, determines the best path
for the datagram.
A subnet has at least one route associated with it, but you can add as many routes as
resources allow. In addition, routes can be dynamically redirected by the TCP/IP
subsystem. For instance, when a SUBNET object enters the STOPPED summary
state, any routes associated with that subnet are automatically redirected by the
subsystem to another available subnet. When adding a ROUTE object, follow the DSM
naming conventions. For more details on object names, see Object Names on
page 3-5.
Required Management Functions
Management of a subsystem involves monitoring and controlling the objects defined in
the subsystem, and monitoring and handling events occurring in the subsystem.
The ability to monitor the TCP/IP subsystem is significant. With the information made
available to you through monitoring, you can make decisions needed to maintain a
productive computing environment.
Monitoring the TCP/IP subsystem includes tasks such as:
•
Obtaining the version level of the subsystem software
•
Obtaining current attribute values for all the objects
•
Obtaining the names of subnets and routes known to the subsystem
•
Obtaining the current values of the statistics counters for all the objects
•
Obtaining information about the current states of all the objects
•
Obtaining information about the openers of the process
•
Retrieving information about events occurring in the subsystem
Once you have gained this information, you can make informed decisions to control
your subsystem. You can take action either programmatically or interactively using the
available commands.
Controlling your subsystem includes tasks such as:
•
Terminating the operation of subnets and routes
•
Adding subnets and routes to the subsystem
•
Changing certain attributes of a process or subnet
•
Removing subnets and routes from the subsystem
•
Resetting the statistics counters to the subsystem default values
•
Initiating the operation of subnets and routes
•
Tracing the activity of a process or subnet
