I am running BCM 12.1 and I'm seeing devices entries with unique host names but the same HostID. All of the entries are from the same device. Two entries are identified by the wired and wireless IP address assignment when the device was unmanaged. The third is the managed device entry on a wired interface but a different IP address.
Device Name IP Address Operating System Name Topology Device Type User Host ID
172.16.56.78 172.16.56.78 Microsoft Windows 7 Enterprise SP1 64-bit Unmanaged Device [same userid in domain\userid format] PC0KST38
172.16.56.85 172.16.56.85 Microsoft Windows 7 Enterprise SP1 64-bit Unmanaged Device [same userid in domain\userid format] PC0KST38
jzllt4037 172.16.28.92 Microsoft Windows 7 Enterprise Edition 64-bit Client [same userid in domain\userid format] PC0KST38
I usually see all entries being reconciled to a single object in BCM once the agent is installed, so I'm definitely missing something. My Connection Management settings are as follows.
Use the host name to uniquely identify device - No
Use host ID to uniquely identify device - No
Use the NetBIOS name to uniquely identify device - Yes
Use the MAC address to uniquely identify device - No
Use the disk serial number to uniquely identify device - No
Automatically Update Device Name - Yes
Case of Device Name - Indifferent
Client Identification Type - Host Name
Lost Client after Delay of - 30
Unit for Lost Client - Days
Lost Relay after Delay of - 24
Unit for Lost Relay - Hours
Allow Duplicate Device Names - No
Automatic Agent Version Upgrade - No
It seems that I should change the unique identifier to HostID rather than Host Name in Connection Management but is device identification strictly by the connection management settings even when the agent is installed? I was under the impression that once the agent was installed, the agent identification process became more robust to track changes on the host.
Just looking for a sounding board. Should I change the unique identifier or is there possibly another issue?
