4\. Configure the new VLAN

**Important Note**

Vlans can be configured on the SBC in these cases:<br>

* Baremetal installation
* VMware installation with Passthrough or SR-IOV network interfaces
* VMware installation with a network interface using vlan ID 4095

\
Vlans should not be configured on the SBC in this case:<br>

* VMware installation with network interfaces using vlans from 1 to 4094

In this case, all interfaces on the SBC should be configured as untagged. Vlans are configured in the VMware port Groups.\
Please check here: [How to add VMware Network Interfaces](https://prosbcdocs.telcobridges.com/initial-installation/1.-instructions-by-platform/virtual-self-hosted-installation/virtual-vmware/adding-network-interfaces-in-vmware)\
\
If VLANs must be configured, follow these steps:<br>

* Enter a name for the VLAN
* If the port is to be used untagged, make sure Untagged is checked.
* If the port is to be used with a 802.1Q tag, uncheck Untagged and enter a VLAN ID.
* Click Create
