The matching criteria for a VLAN impact propagation group are the VLAN class and two of its attributes:
By default, the value of the CreationClassName attribute is set to “VLAN,” and the value of the VLANKey attribute is undefined. The value that you specify for the VLANKey attribute determines which VLANs become members of a VLAN impact propagation group.
The value of the VLANKey attribute is included in the value of the Name attribute for a VLAN object in the following way:
The value of the VLANKey attribute distinguishes a VLAN from all other VLANs in the managed topology and consists of any combination of the following identifiers:
<management domain name> <user-defined VLAN tag> <VLAN number (ID)>
An example of a VLANKey value consisting of just a management domain name is:
An example of a VLANKey value consisting of a user-specified VLAN tag and a VLAN number is:
An example of a VLANKey value consisting of just a VLAN number is 1.
