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
ID; 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 ID; 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.
