System information

348 Observer Suite: SNMP Management
Lists have only one limitation regarding type of object: they cannot display tabular
objects. Lists can display text, IP addresses, descriptions, and numeric variables, but not
tables.
Lists are best for objects that have a one-to-one relationship. For example: a
statistic that does not change, such as SystemName; or a statistic that does
not have a variable number of data points, such as RouteMetrics. Tables are
best to display items that may have a variable number of responses, such as
a list of current connections by IP address.
To receive list information from an agent, select the Lists item in the SNMP Agents
request area, then select the List tree item you wish to view.
List requests are created and modified using the MIB Editor. See “Using the MIB Editor”
on page 354.
When you select a list menu request, SNMP Management Console sends the request to the
agent and (if the agent is running and configured properly) receives a reply, which can be
viewed in the list display in the agent information window. If necessary, SNMP Extension
will re-send the request.
Read Values Display
Some objects in the list are writable, which means you can use SNMP Management
Console to set the value of the object remotely. Writable objects display “[RW]” in the
Access column of the display. Read-only objects show “[RO]” in the Access column.
Writable Object Setting
To define a setting for a writable object:
1. Select the writable object entry in the agent window.
2. Enter or select a new value for the object in the textbox that is displayed at the bottom
of the window.
3. Click the S
ET button. SNMP Management Console sets the value of the writable
object and repeats the original request to make sure that the value was changed.
