POSTED BY Zevenet | 25 October, 2021

VLAN interfaces (VLAN tagging) permit isolating logical network architectures at OSI layer 2 over the same physical NIC interface, each with its independent routing table. See how to configure and manage VLAN interfaces below.

VLAN Interfaces List

This table lists all the VLAN interfaces configured in the system.

The actions available for the selected interfaces are:

  • Create VLAN. This option pops out the VLAN form for creating a VLAN interface.
  • Bring up. Starts the interface and configures it to accept traffic.

The following are the column names of the table above.

Name. The name of the VLAN interface. It also indicates the parent NIC, bonding, and VLAN tag.
Alias. A name to easily identify an interface within a farm or any other service.
IP. Network-layer IP address of the VLAN interface if configured. It Supports IPv4 and IPv6.
MAC. Link-layer address of the VLAN interface. The VLAN will inherit it from the parent NIC or the bonding interface if it is not configured.
Netmask. A subnet mask of the VLAN interface that is configured. The NETMASK can only be configured if the IP address is configured too.
Gateway. Default gateway used by the VLAN interface if configured. It must be on the same subnet.
Status. The status of a given VLAN interface. These are the status indicators:

  • Green. If the virtual interface is UP.
  • Red. If the virtual interface is DOWN.

Actions. The following are the actions for the interface.

  • Edit. Changes the VLAN configuration like its IP address, MAC address, netmask, and gateway.
  • Bring down. It shuts down the interface and stops it from accepting traffic.
  • Delete. Clears the configuration and removes the VLAN interface.
