Virtual Wire Interface
- Network > Interfaces > Ethernet
A virtual wire logically binds two Ethernet interfaces together, allowing for all traffic to pass between the interfaces, or just traffic with selected VLAN tags (no other switching or routing services are available). You can create virtual wire subinterfaces to classify traffic according to an IP address, IP range, or subnet. A virtual wire requires no changes to adjacent network devices. A virtual wire can bind two Ethernet interfaces of the same medium (both copper or both fiber optic), or bind a copper interface to a fiber optic interface.
To set up a virtual wire, decide which two interfaces to bind (
) and configure their settings as described in the following table.
If you are using an existing interface for the virtual wire, first remove the interface from any associated security zone.
Virtual Wire Interface Setting
The interface name is predefined and you cannot change it.
Enter an optional description for the interface.
If the firewall supports multiple virtual systems and that capability is enabled, select a virtual system for the interface or click
Virtual Systemto define a new vsys.
Select a security zone for the interface, or click
Zoneto define a new zone. Select
Noneto remove the current zone assignment from the interface.
Select a specific interface speed in Mbps or select
autoto have the firewall automatically determine the speed. Both interfaces in the virtual wire must have the same speed.
Select whether the interface transmission mode is full-duplex (
full), half-duplex (
half), or negotiated automatically (
auto). Both interfaces in the virtual wire must have the same transmission mode.
Select whether the interface status is enabled (
up), disabled (
down), or determined automatically (
Select to enable Link Layer Discovery Protocol (LLDP) on the interface. LLDP functions at the link layer to discover neighboring devices and their capabilities.
If LLDP is enabled, select an LLDP profile to assign to the interface or click
LLDP Profileto create a new profile (see Network > Network Profiles > LLDP Profile). Select
Noneto configure the firewall to use global defaults.
Enable in HA Passive State
If LLDP is enabled, select to configure an HA passive firewall to pre-negotiate LLDP with its peer before the firewall becomes active.
If LLDP is not enabled, select to configure an HA passive firewall to simply pass LLDP packets through the firewall.
