IP address discovery and reconciliation - BlueCat Integrity - 9.5.0

Address Manager Administration Guide

Product name
BlueCat Integrity

IP address discovery and reconciliation discovers IPv4 and IPv6 addresses on your network and returns their host information to Address Manager. After discovering the addresses on your network, you can add them to your Address Manager configuration.

Address Manager uses SNMP interrogation against one or more routers, and Layer 2/3 switches to discover the IP address, hardware address, and DNS host name (if DNS is available) for hosts on your network. Link Layer Discovery Protocol (LLDP) is also supported.

Discovering and reconciling Layer-2 switch port information and VLAN information for non-Cisco switches is supported in Address Manager. Address Manager also supports discovering and reconciling /32 device addresses when using SNMP policies. However, this isn't supported when using the pingsweep method. The IP reconciliation discovery tool can only detect devices connected to the access mode switch ports. Information won't be relayed to Address Manager if the device is connected through a port operating in trunk mode.

Address Manager displays the results on the Reconciliation Policy page. From this page, you can reconcile the IP addresses in Address Manager with the discovered IP addresses.

IP address discovery is controlled through an IP Reconciliation Policy. The policy includes address and SNMP information for a router(s) or switch(es), scheduling parameters to determine when and how often the discovery process runs, and other parameters. The discovery can run at scheduled intervals and on demand.
Note: You need to be an administrative user to create and run IP reconciliation policies.

The steps for creating IP reconciliation processes, running them, and working with the results are similar for both IPv4 and IPv6 policies. However, there are minor differences in the options available and the information returned for IPv4 and IPv6 networks.
