IP discovery overview

Rediscovery updates can occur using any of the following methods:

• Lazy polling.

• Adaptive discovery (triggered by snmp traps).

• Manual rediscovery (refer to “IP Rediscovery” on page 135).

Configuration requirements

Before configuring discovery, obtain the following information:

• SNMPv1 and SNMPv2c read-write community strings or SNMPv3 read-write credentials for the

devices to be included in discovery. Make sure that devices you want to manage have the

SNMP credentials configured. For more information, refer to “IP SNMP credentials” on

page 72.

• Device IP addresses and subnets to probe during discovery. For more information, refer to

“Configuring address ranges” on page 92, “Adding user credentials” on page 78, and

“Defining global setting preferences” on page 86.

Discovery of IPv6 addresses

The Management application discovers both IPv4 and IPv6 addresses of devices that have the IPv6

MIB objects implemented. The Management application discovers IPv4 addresses of devices

running IPv6 that do not have IPv6 MIB support. For more information, refer to “Defining global

setting preferences” on page 86.

NOTE

IronWare IPv6 devices must support the set of MIBs presented in Table 15 on page 60. To determine

IPv6 MIB object support on the device, refer to the release notes and user documentation for your

IPv6 product.

NOTE

Third-party IPv6 devices must support the set of MIBs presented in Table 16 on page 62.

MIB support

IP discovery requires SNMP management information base (MIB) support on the device for

management information collection. For a list of required MIBs, refer to Table 15 on page 60 or

Table 16 on page 62.
