 # VLAN Translation Policies
 
-!!! info "This feature was introduced in NetBox v4.2."

 VLAN translation is a feature that consists of VLAN translation policies and [VLAN translation rules](./vlantranslationrule.md). Many rules can belong to a policy, and each rule defines a mapping of a local to remote VLAN ID (VID). A policy can then be assigned to an [Interface](../dcim/interface.md) or [VMInterface](../virtualization/vminterface.md), and all VLAN translation rules associated with that policy will be visible in the interface details.
 
 There are uniqueness constraints on `(policy, local_vid)` and on `(policy, remote_vid)` in the `VLANTranslationRule` model. Thus, you cannot have multiple rules linked to the same policy that have the same local VID or the same remote VID. A set of policies and rules might look like this:

 # VLAN Translation Rules
 
-!!! info "This feature was introduced in NetBox v4.2."
-
 A VLAN translation rule represents a one-to-one mapping of a local VLAN ID (VID) to a remote VID. Many rules can belong to a single policy.
 
 See [VLAN translation policies](./vlantranslationpolicy.md) for an overview of the VLAN Translation feature.
