The SNMP devices page allows you to customize the discovery parameters
for SNMP devices.
Complete the following steps to configure discovery preferences for
SNMP devices:
- In IBM Director Console,
click .
- In the Discovery Preferences window on the SNMP Devices page, configure
the discovery preferences for SNMP devices.
- In the Auto-discover period (hours) field,
select the frequency with which IBM Director Server attempts
to discover SNMP devices automatically. The possible range is one to 168 hours
(seven days). By default, autodiscovery is disabled.
- In the Presence Check period (minutes) field,
select the frequency that IBM Director Server checks
the status of each SNMP device. A presence check detects whether an SNMP device
is online or offline. The possible range is one to 240 minutes (four hours);
this feature also can be disabled. By default, a presence check is set to
occur every 15 minutes.
- Select the Auto-add unknown agents which contact
server check box to ensure that IBM Director Server adds
objects for newly-discovered SNMP devices to the Group Contents pane.
- Configure seed addresses for SNMP discovery:
- In the IP Address and Subnet masks group
box, specify the seed addresses. You can specify multiple IP addresses; the
addresses are searched concurrently. By default, the IP address of the management
server is added to this list. To optimize the chance of discovering all SNMP
devices, be sure to specify the IP addresses for routers and DNS servers.
During the discovery operation, IBM Director Server locates
the address tables located on the specified devices and adds those addresses
to the list of addresses to search. The process is repeated for every new
SNMP device that is discovered from the new addresses. The discovery operation
continues until no more addresses are found.
- In the SNMP Version field, select the
SNMP version.
- In the Community Names field, type the
community names and click Add. Continue until all community
names are added. For SNMP versions 1 and 2c, be sure to order the community
names appropriately.
