The IP Manager uses Internet Control Message Protocol (ICMP) and Simple Network Management Protocol (SNMP) to discover IPv4-only, IPv6-only, and dual-stack systems in the managed network environment. A dual-stack system is configured with both IPv4 (32-bit) and IPv6 (128-bit) addresses.
The IP Manager supports IPv4 ICMP (also known as ICMPv4), IPv6 ICMP (also known as ICMPv6), IPv4 SNMP, and IPv6 SNMP. Because many Management Information Bases (MIBs) have not yet been modified to accommodate IPv6 addresses, certain IP Manager features are not available to IPv6.
Starting from IP 8.1.1, IPv6 addresses on a device that are link-local (FE80::), site-local (FEC0::), multicast (FF00::), or loopback (::1) do not get discovered and are not added to the topology. For example, a valid link-local IPv6 address FE80:0:0:0:20F:35FF:FEC1:2400, will not be discovered.
The IP Manager also supports SNMPv1, v2c, and v3.
The IP Manager User Guide provides information about ICMP, SNMP, and Asynchronous SNMP (ASNMP). Unless specified otherwise, the term ICMP is used to refer to IPv4 and IPv6 ICMP polling, and the term SNMP is used to refer to IPv4 and IPv6 SNMP polling.
