Threshold groups for VLAN impact propagation are used to prevent device impact propagation in certain (user-specified) VLANs, such as management VLANs and default VLANs. These groups are described in the VMware Smart Assurance IP Manager User Guide, under “Performing tasks in the Thresholds tab”. The default VLAN impact propagation groups do not automatically appear. You must issue a certain command for the default VLAN impact propagation groups to appear.

The VMware Smart Assurance IP Manager Reference Guide provides information on the default VLAN impact propagation groups, their target classes and matching criteria, and their default settings. The target class for all VLAN impact propagation groups is VLAN.

  • The only setting that is available to a VLAN impact propagation group is “Problem Impact propagation policy over VLANs.” The VMware Smart Assurance IP Manager Reference Guide provides information on the “Problem Impact propagation policy over VLANs” setting parameters

  • The Other VLANs group has the lowest priority. VLANs that do not match the criteria for the VLANs group become members of the Other VLANs group.
