You create an IP tag filter for one of the IP Managers so that the IP Manager can distinguish between the overlapping addresses that belong to the two different IP management domains. The use of the IP tag filter enables the IP Manager to do the following:
Store in their respective repositories the IP objects that represent the overlapping IP addresses that are used by the two locally distinct groups of devices in the two IP management domains.
IP tag filter groups provide a means to create an IP tag filter and specify a unique tag for a group of devices that share an IP address space with another group of devices. The procedure for creating IP tag filter groups is presented in the VMware Smart Assurance IP Manager User Guide.
The IP Manager with the IP tag filter will use the “IP-<IP address>/<tag>” naming scheme to name an IP address instance that is collected from its domain. The IP Manager without the IP tag filter will use the standard naming scheme of “IP-<IP address>” to name an IP address instance that is collected from its domain.
For example, if you create an IP tag filter group that has a “Domain_A” tag and matching criteria that allow the devices in the management domain for IP Manager_A to become members of the group, IP Manager_A will assign the name IP-<IP address>/Domain_A to the IP addresses that it collects from its management domain. IP Manager_B will assign the name IP-<IP address> to the IP addresses that it collects from its management domain.
