Attribute Meaning
VLAN Port Type By default, this is Q, indicating that it is to operate in the existing manner.
The other option is Q-in-Q, which indicates that it must be adding and
removing the S-Tag, and adding a C-Tag if necessary for untagged packets.
The VLAN Port type corresponds to the Ethernet port of the SM/BHS.
Currently, the internal management interfaces will always operate as Q ports.
Accept QinQ Frames This option is valid for the Q-in-Q port so that the user may force blocking of
existing 802.1ad Q-in-Q frames. This way, only untagged or single tagged
packets will come in and out of the Ethernet interface. If a Q-in-Q frame is
about ingress or egress the Ethernet interface and this is disabled, it is
dropped and a filter entry will show up on the VLAN Statistics page as
DVLAN Egress or DVLAN Ingress.
Allow Frame Types Select the type of arriving frames that the SM must tag, using the VID that is
stored in the Untagged Ingress VID parameter. The default value is All
Frames.
Tagged Frames Only: The SM only tags incoming VLAN-tagged frames
Untagged Frames Only: The SM will only tag incoming untagged frames
Dynamic Learning Specify whether the SM must (Enable) or not (Disable) add the VIDs of
upstream frames (that enter the SM through the wired Ethernet interface) to
the VID table. The default value is Enable.
VLAN Aging Timeout Specify how long the SM/BHS must keep dynamically learned VIDs. The
range of values is 5 to 1440 (minutes). The default value is
25 (minutes).
Note
VIDs that you enter for the Untagged Ingress VID and
Management VID parameters do not time out.
Management VID Enter the VID that the SM/BHS must share with the AP/BHM. The range of
values is 1 to 4095. The default value is 1.
