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 “Using a policy setting to prevent VLAN impacts” on page 197.

The default VLAN impact propagation groups do not automatically appear. As explained in “Creating VLAN impact propagation group objects” on page 200, Auser must issue a certain command for the default VLAN impact propagation groups to appear.

Default VLAN impact propagation groups for the IP Manager shows 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.

Table 1. Default VLAN impact propagation groups for the IP Manager

VLAN impact propagation group

Target class and matching criteria

Default settings

VLANs

VLAN with attributes:

  • IsManaged = TRUE

  • CreationClassName = VLAN

  • VLANKey = <user-defined value>

Problem impact propagation policy over VLANs

Other VLANs

VLAN with attribute:

  • IsManaged = TRUE

No default settings

Two things to note about Default VLAN impact propagation groups for the IP Manager:

  • The only setting that is available to a VLAN impact propagation group is “Problem Impact propagation policy over VLANs.”

  • 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.
