9.6.2.1 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 (e.g.,
OAM) is set to zero on outgoing packets. This method is called Priority Tagging (p tag without Q
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.
9.6.3 Getting Started with VLANS and Multiple IPs
By default the MediaPack 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 MediaPack into a VLAN and multiple IPs network using the
Embedded Web Server (refer to Section 9.6.3.1 below) and ini file (refer to Section 9.6.3.2 on
page 200). Table
9-2 below shows an example configuration that is implemented in the following
sections.
