Conflicts occur when the BlueCat Cisco ACI workflow imports ACI components into BlueCat Address Manager (BAM), where BAM objects with the same names already exists. These conflicts are resolved as follows.
Conflicts when importing ACI fabrics
ACI Fabrics and BAM IPv4 Blocks/Networks:
New BAM IP4 blocks and networks are always created, except when the BlueCat Cisco ACI subnet range overlaps with an existing BAM IP4 block. The overlapping subnet range could be larger, smaller, or equal to the IP4 block range, which will result in the overlapping block being dropped.
ACI Devices:
If the BAM Configuration is empty, everything is imported. Otherwise, conflicts are handled as follows:
The ACI Fabric network range differs from the BAM IPv4 network range: None of the ACI Fabric devices will be imported. ACI fabric devices are imported only if the ACI network and BAM IP4 network ranges are identical.
For example, with the following conflicts, ACI Fabric devices will not be imported:
ACI fabric network CIDR:
10.0.0.0/16BAM IP4 network CIDR:
10.0.0.0/24ACI fabric network CIDR:
10.0.0.0/16BAM IP4 network CIDR:
10.0.0.0/8
-
A BAM Device with the same name as the ACI Device already exists: The BAM Device will be deleted and a new BAM Device will be created for the ACI Device.
A BAM device has the same IP address as an existing ACI device, but with a different name: The BAM Device will not be modified or deleted. The ACI device will not be imported.
Conflicts when importing ACI Tenants
The conflict resolution depends on whether the Overwrite Existing option was selected when configuring the Cisco ACI import. (See Using BlueCat Cisco ACI.)
If the Overwrite Existing import option is cleared
New BAM IPv4 Blocks and Networks are created except when the Cisco ACI subnet range overlaps with an existing BAM IPv4 Block. The overlapping subnet range could be larger, smaller, or equal to the IPv4 Block range, which will result in the overlapping block being dropped.
If the Overwrite Existing import option is selected
-
Cisco ACI subnets and BAM IPv4 Blocks/Networks:
New BAM IP4 blocks and networks are created except when the Cisco ACI subnet range overlaps with an existing BAM IPv4 Block. The overlapping subnet range could be larger, smaller, or equal to the IPv4 Block range.
Note: When the ranges overlap, ACI Devices in the subnet will also not be imported. -
Devices:
New BAM Devices are created except for the following cases:
-
A Device exists in BAM whose name matches the MAC address of the Cisco ACI device being imported.
-
A Device exists in BAM with an IP address that matches the primary or secondary IP address of the Cisco ACI Device being imported.
-
The ACI Device is in a subnet with an overlapping range (as described above).
