Virtual Wire Subinterface
- Network > Interfaces > Ethernet
Virtual wire (vwire) subinterfaces allow you to separate traffic
by VLAN tags or a VLAN tag and IP classifier combination, assign
the tagged traffic to a different zone and virtual system, and then
enforce security policies for the traffic that matches the defined
criteria.
To add a Virtual Wire Interface select
the row for that interface, click Add Subinterface,
and specify the following information.
Virtual Wire Subinterface Settings | Description |
---|---|
Interface Name | The read-only Interface Name displays
the name of the vwire interface you selected. In the adjacent field, enter
a numeric suffix (1-9,999) to identify the subinterface. |
Comment | Enter an optional description for the subinterface. |
Tag | Enter the VLAN tag (0-4,094) for the subinterface. |
Netflow Profile | If you want to export unidirectional IP
traffic that traverses an ingress subinterface to a NetFlow server,
select the server profile or click Netflow Profile to
define a new profile (see Device > Server Profiles > NetFlow).
Selecting None removes the current NetFlow
server assignment from the subinterface. |
IP Classifier | Click Add and enter
an IP address, IP range, or subnet to classify the traffic on this vwire
subinterface. |
Virtual Wire | Select a virtual wire, or click Virtual
Wire to define a new one (see Network > Virtual Wires).
Select None to remove the current virtual
wire assignment from the subinterface. |
Virtual System | If the firewall supports multiple virtual
systems and that capability is enabled, select a virtual system
(vsys) for the subinterface or click Virtual System to
define a new vsys. |
Security Zone | Select a security zone for the subinterface,
or click Zone to define a new zone. Select None to
remove the current zone assignment from the subinterface. |
