BSU VLAN Configuration
The HTTP Interface to configure BSU VLAN parameters is shown in the following figure.
BSU Function – Trunk Mode SU Function – Trunk Mode SU Function – Access Mode
Up to 256 VLAN IDs can be
configured on a BSU.
BSU discards all untagged
frames received from the
Ethernet interface or from any of
the associated SUs
(unexpected).
If a valid VLAN ID is configured,
BSU forwards only VLAN-tagged
frames received from the
Ethernet interface or from any of
the associated SUs that are
tagged with the configured VLAN
IDs; it discards all other tagged
frames.
If a valid management VLAN ID is
configured, BSU allows only
management frames tagged with
the configured management
VLAN ID to access it.
If a valid management VLAN ID is
configured, BSU tags all
management frames generated
by the BSU with the configured
management VLAN ID and
priority.
If the management VLAN ID is
configured as -1 (untagged), BSU
allows only untagged
management frames to access it.
Up to 16 VLAN IDs can be
configured on an SU.
SU discards all untagged frames
received from the Ethernet
interface or from the BSU
(unexpected).
If a valid VLAN ID is configured,
SU forwards only VLAN-tagged
frames received from the
Ethernet interface or from the
BSU that are tagged with the
configured VLAN IDs; it discards
all other tagged frames.
If a valid management VLAN ID is
configured, SU allows only
management frames tagged with
the configured management
VLAN ID to access it.
If a valid management VLAN ID is
configured, SU tags all
management frames generated
by the SU with the configured
management VLAN ID and
priority.
If the management VLAN ID is
configured as -1 (untagged), SU
allows only untagged
management frames to access it.
SU discards all tagged frames received
from the Ethernet interface and all
untagged frames received from the
BSU (unexpected).
SU tags all untagged frames received
from the Ethernet interface with the
configured Access VLAN ID and
forwards them to the BSU.
SU untags all tagged frames received
from the BSU that are tagged with the
configured Access VLAN ID and
forwards them to the Ethernet
interface; it discards all other tagged
frames from the BSU.
If a valid management VLAN ID is
configured, SU allows only
management frames tagged with the
configured management VLAN ID to
access it from the BSU.
If a valid management VLAN ID is
configured, SU tags all management
frames generated by the SU with the
configured management VLAN ID and
priority and forwards them to the BSU.
If the management VLAN ID is
configured as -1 (untagged), SU allows
only untagged management frames to
access it from the BSU.
SU allows only untagged management
frames to access it from the Ethernet
interface, regardless of the value of the
management VLAN ID.
