Operation
Outgoing packets (from the gateway to the switch):
All outgoing packets are tagged, each according to its interface (control, media or OAM).
If the gateway’s native ID is identical to one of the other IDs (usually to the OAM ID), this
ID (for example, OAM) is set to zero on outgoing packets
(VlanSendNonTaggedOnNative = 0). This method is called Priority Tagging (p tag
without Q tag). If the parameter VlanSendNonTaggedOnNative is set to 1, the gateway
sends regular packets (with no VLAN tag).
Incoming packets (from the switch to the gateway):
The switch sends all packets intended for the gateway (according to the switch’s
configuration) to the gateway without altering them. For packets whose VLAN ID is
identical to the switch’s PVID. In this case, the switch removes the tag and sends a
packet.
The gateway only accepts packets that have a VLAN ID identical to one of its interfaces
(control, media or OAM). Packets with a VLAN ID that is 0 or packets without a tag are
accepted only if the gateway’s native VLAN ID is identical to the VLAN ID of one of its
interfaces. In this case, the packets are sent to the relevant interface. All other packets
are rejected.
Getting Started with VLANS and Multiple IPs
By default the gateway operates without VLANs and multiple IPs, using a single IP address,
subnet mask and default gateway IP address. This section provides an example of the
configuration required to integrate the gateway into a VLAN and multiple IPs network using
the Embedded Web Server (see
Integrating Using the Embedded Web Server
) and
ini
file
(see
Integrating Using the ini File
).
Table 54
shows an example configuration that is implemented in the following sections.
