# Reconfiguration

During reconfiguration, you can only add or remove virtual interfaces, which determines whether the system configures an IP interface for the associated network on the server. You can also modify the trunk VLAN list using the Network configuration wizard, where adding a VLAN includes it on all server ports using that network, and removing a VLAN removes it from those ports. These changes do not update the host OS automatically, so you must run the appropriate workflow to apply the required configuration on the compute host.

**Supported Actions from Reconfigure Instance**

- **Add a new virtual interface** for one of the trunk VLANs in the network specified for the primary interface
- **Delete a virtual interface**  for one of the trunk VLANs that was previously added

**Supported Actions from Network Edit**

- **Add a VLAN to the trunk VLAN list** adds the VLAN to the server ports of servers consuming this network
- **Delete a VLAN from the trunk VLAN list**  removes the VLAN from the server ports of servers consuming this network
