# VLAN

VLAN (802.1Q) is operational only in bridge mode.

## VLAN Configuration

### Mode

The RF interface operates in VLAN "Tagged" mode only.

Untagged: Devices on this interface are not using VLAN tags. Incoming (ingress) packets are tagged with the port VLAN ID (PVID). VLAN tags are removed on outgoing (Egress) packets. See the "Advanced Settings" section for more options.

Tagged: Devices on this interface are using VLAN tags. Incoming (ingress) packets are forwarded with their VLAN ID. Outgoing (Egress) packets are also keeping their VLAN tags. See the "Advanced Settings" section for more options.

### Port VLAN ID

Set the port VLAN ID (PVID)

### Member Of Management VLAN (bridge mode)

This parameter is only active when the "Management VLAN" parameter is enabled (see "Home -> Basic Settings") and the Viper is operating in bridge mode. User can access the internal applications of the Viper (HTTP, FTP, Command Shell) through this port if "Member of Management VLAN" is enabled. This is true only for ports of type "Tagged". Ports of type "Untagged" can always access the internal functions of the Viper (HTTP, FTP, Command Shell).

### Member Of Management VLAN (router mode)

This parameter is only active when the Viper is operating in router mode and VLAN is enabled. Disable "Member of Management VLAN" when you dont want external applications to access internall applications using the IP address (and PVID if set) of this interface.

### Advanced Settings

Change the advanced settings (the default actions are highlighted).
