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.
