Command History
This guide is platform-specic. For command information about other platforms, see the relevant Dell
Networking OS Command Line Reference Guide.
The following is a list of the Dell Networking OS version history for this command.
Version Description
9.8(0.0P5) Introduced on the S4048-ON.

Usage Information
You can attach an interface to either a nondefault VRF or a management VRF.
To assign a port-back to a default VRF, remove the VRF association from the interface. You can use this only
if there is no IP address congured on the interface.
There must be no prior Layer 3 conguration on the interface when conguring VRF.
You must enable VRF before using this command.
You can congure an IP subnet or address on a physical or VLAN interface that overlaps the same IP subnet
or address congured on another interface only if the interfaces are assigned to dierent VRFs. If you assign
two interfaces to the same VRF, you cannot congure overlapping IP subnets or the same IP address to
them.
