Add and remove VLANs

Use this page to add and remove VLANs in the NetFoundry zLAN console.

VLANs overview

The VLANs tab displays all configured VLAN interfaces. If no VLANs exist, you'll see "No interfaces to display." To add a new VLAN, click + New VLAN.

Add a VLAN

1. Click + New VLAN in the VLANs tab.

2. Fill in the ID (VLAN number) and select the Parent interface (e.g., ens5).

3. Enter the IP & CIDR for the VLAN interface, or toggle DHCP ON or OFF as needed.

4. Configure additional options:

   • Enable Discovery Mode: Allows the VLAN to be discovered by other devices.
   • Allow ICMP: Permits ping and other ICMP traffic.
   • Allow SSH: Enables SSH access to the VLAN.
   • Enable Masquerade: Allows NAT for outbound traffic.
   • Enable VRRP: Enables Virtual Router Redundancy Protocol (VRRP) for high-availability failover. zLAN doesn't manage VRRP—enabling this toggle changes how the firewall handles local network traffic on that interface. Configure VRRP separately using your own tooling.
   • Enable OSPF: Enables Open Shortest Path First routing.
   • Enable EIGRP: Enables Enhanced Interior Gateway Routing Protocol.

5. Click Add Another to add more VLANs, or Done to finish.

VLAN configuration

After adding a VLAN, it appears in the VLANs list. Select a VLAN to view or change its configuration, rules, or details. Use the Config tab to toggle features for the selected VLAN.

Remove a VLAN

1. Select the VLAN you want to remove from the VLANs list.
2. Click Remove in the top right corner.
3. Confirm the deletion when prompted.
4. Click Save to apply the change.

note

Removing a VLAN does not take effect until you click Save.
