Discovery Preferences window: SNMP Devices page

This topic describes the Discovery Preferences window: SNMP Devices page.

Introduction

You can use this dialog to set SNMP discovery parameters to search for specific SNMP devices or groups of devices.

Fields

IP Addresses and Subnet Masks
Use the left panel to specify starting or seed addresses from which you can begin a discovery. You can specify one or more addresses: multiple addresses are searched concurrently. By default, the address of the IBM Director Server is added to this list. To optimize discovery, specify interconnect devices, like routers and name servers, as seed addresses. During discovery, address tables found on the specified devices are then searched, and the search continues until no more addresses are located.
Note: Specifying a subnet of 0.0.0.0 for any address in the seed list causes all SNMP devices that are located to be added to the IBM Director Console.
Add
Add an IP address, an IP address and subnet pair, or both. If no subnet is specified, the discovery function uses the subnet of the specified device.
Import
Add IP addresses from a text file. Use the file dialog to specify the location of the file. This file should be a simple list of IP addresses, with one address per line.
Note: If the network drives on the IBM Director Server are mapped using a different user name or password than the user name or password specified for the IBM Director service during installation (such as user name or password of the IBM Director support service), the network drives will be unavailable due to access limitations.
Replace
Change the selected IP address or IP address and subnet pair.
Remove
Remove the selected IP address or IP address and subnet pair from the list.
SNMP Version
Select the version of SNMP being used: SNMPv1, SNMPv2c, or SNMPv3.
SNMPv1 and SNMPv2c
If you select either of these values, then complete the following information.
Community Names
Use the right panel to specify the community names of systems that have restricted SNMP access; otherwise, discovery cannot include restricted systems as SNMP devices in the Groups pane of the IBM Director Console.
Note: The community names should be ordered from top to bottom in increasing level of access restriction.
Add
Add a community name to the list.
Replace
Change the selected community name.
Remove
Remove the selected community name from the list.
SNMPv3
If you select this value, then complete the following information.
Profile Names
Use the right panel to specify the profile names of systems that have restricted SNMP access; otherwise, discovery cannot include restricted systems as SNMP devices in the Groups pane of the IBM Director Console.
Add
Add a profile name to the list.
Remove
Remove the selected profile name from the list.
SNMP Devices
Configuration of both the automatic discovery and presence check intervals.
Auto-discover period (hours)
This setting is used to control how often the IBM Director Server will attempt to automatically discover SNMP devices for management. This feature can be disabled (the default) or set to a period of 1 - 168 hours (7 days).
Presence Check period (minutes)
This setting is used to control how often the IBM Director Server checks the status of each SNMP device it can manage. The presence check period determines how quickly the IBM Director Server detects that a system has gone offline (due to a problem or being shutdown), or has come online. The automatic presence check can be disabled, or set to repeat every 1 - 240 minutes (4 hours). The default setting is 15 minutes.
Auto-add unknown agents which contact server
When this check box is selected, devices that contact IBM Director Server, are automatically added.
