you configure for each VLAN that the Bridge secures. The
routable VLAN IDs received on clear interfaces are translated,
according to the routing map, into non-routable IDs and
transmitted on an encrypted interface, and vice versa (non-
routable VLAN IDs received on encrypted interfaces are
translated into routable IDs and transmitted on a clear
interface).
NOTE: VLAN
translation occurs
only on traffic received
in one zone (clear or en-
crypted) and transmit-
ted in the other zone.
VLAN IDs passed from
one interface to another
within the same zone
are not translated.
Routable VLAN IDs must therefore be part of a trunk in the
clear zone, and
Non-Routable VLAN IDs must be part of a trunk
on an encrypted port. VLAN IDs that are passed within the
same zone do not have to be present in the VLAN routing map.
The Bridge can support up to 24 VLANs in translate mode:
each translation requires two VLAN IDs, for a maximum of 48
VLAN IDs on the VLAN translation map.
If the Bridge's encrypted and clear interfaces reside on the
same OSI layer-2 switch, use
Translate mode.
3.9.2 Native VLAN
The native VLAN can be used as management VLAN, allowing
you to use tagged traffic to manage the Bridge.
On an interface with a VLAN
Switching Mode of Trunk, you can
access the Bridge’s management interface only with packets
tagged with the Bridge’s
Native VLAN ID. You can manage the
Bridge on an interface with a VLAN
Switching Mode of Access
only with untagged packets and only when the interface’s
Default VLAN ID matches the Bridge’s global Native VLAN ID.
You can reconfigure the Bridge to use a native VLAN ID other
than 1 (the default), which automatically adds the new number
to the Bridge’s VLAN ID table (described in Section 3.9.3). If
the new ID is already present on the VLAN ID table, it will
simply be selected as the
Native VLAN ID.
VLAN functions are available only in Advanced View.
To configure basic VLAN settings
1 Log on to the Bridge GUI through an Administrator-level
account and select
ADVANCED VIEW in the upper right corner
of the page, then
Configure -> VLAN from the menu on the
left.
2 In the VLAN Settings frame, enter new values for those
settings you want to configure (described above).
3 Click APPLY in the upper right of the screen (or RESET
screen settings to cancel your changes).
4 If you selected a VLAN Mode of Normal or Translate, refer to
Section 3.9.3 to configure additional VLANs. For
Translate
mode, refer to Section 3.9.4 to create VLAN map records.
You cannot configure VLANs when
STP or FastPath Mesh is
selected as the Bridge’s
Bridging Mode (refer to Section 3.2).
