4.4.3 Packet
Classification
The AN-80i PMP deployment can be configured for use with VLAN tagged traffic,
untagged traffic, or a combination these two types. Ingress packets received on the
Ethernet port are classified according to the criteria in the following tables. Note that
specific cases are applied for packets with known addresses and unicast packets, etc.
Refer to the Group and Connection definitions later in this section.
Table 9: Web - PMP - Sector Controller Packet Classification
Type
Received on Ethernet port
Received on wireless port
Packet has a
VLAN tag
AND
a
Group has been
defined for this
VID.
Packet with VID matching a Group
definition has the matching VLAN
tag (outermost only) removed and
packet is forwarded over the
wireless interface to all Group
members.
a) Packet may optionally be re-
broadcast (unmodified) over the
wireless interface to all Group
members.
b) VLAN tag with VID for this Group
is added (outermost only) and
packet is forwarded over the sector
controller Ethernet interface.
Packet does not
have a VLAN tag
OR
Packet has a
VLAN tag
AND
no
Group exists for
this VID
.
Pass through Group exists:
Packet is forwarded
(unmodified) over the wireless
interface to all Group members.
No Pass through Group:
Packet is discarded.
Pass through Group exists:
a) Packet may optionally be re-
broadcast (unmodified) over the
wireless interface to all Group
members.
b) Packet is forwarded
(unmodified) over the sector
controller Ethernet interface.
No Pass through Group:
Packet is discarded.
Table 10: Web - PMP - Subscriber Packet Classification
Type
Received on Ethernet port
Received on wireless port
Packet has a
VLAN tag
AND
a
Group has been
defined for this
VID.
Packet with VID matching a Group
definition has the matching VLAN
tag (outermost only) removed and
packet is forwarded over the
wireless interface to the sector
controller.
VLAN tag with VID for this Group is
added (outermost only) and packet
is forwarded over the subscribers
Ethernet interface.
Packet does not
have a VLAN tag
OR
Packet has a
VLAN tag
AND
no
Group exists for
this VID
Pass through Group exists AND
subscriber is a member:
Packet is forwarded
(unmodified) over the wireless
interface to the sector
controller.
Subscriber is NOT a member of
Pass through group:
Packet is discarded.
Pass through Group exists AND
subscriber is a member:
Packet is forwarded (unmodified)
over the subscriber Ethernet
interface.
Notes:
1. The pass through group can be used to transparently pass VLAN traffic through to the
subscriber local network.
2. The separate processing at the sector controller (Group) and subscriber (Connection) can be
used to re-map VLANs from the core network to the subscriber local network.
