Brocade Communications Systems IP250 Configuration requirements, Discovery of IPv6 addresses

3 IP discovery overview

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 46.

•Device IP addresses and subnets to probe during discovery. For more information, refer to “Configuring address ranges” on page 66, “Adding user credentials” on page 52, and “Defining global setting preferences” on page 60.

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 60.

NOTE

IronWare IPv6 devices must support the set of MIBs presented in Table 10 on page 34. 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 11 on page 36.

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 10 on page 34 or Table 11 on page 36.
