VLAN tab of BHM
Figure 13
VLAN tab of BHM
In the
VLAN
tab of BHS, you may set the following parameters.
Table 12
BHM VLAN tab attributes
Attribute
Meaning
VLAN
Specify whether VLAN functionality for the BHM and all linked
BHS must be (
Enabled
) or may not (
Disabled
) be allowed. The
default value is
Disabled
.
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 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.
Management VID
(Range 1-4094)
Enter the VID that the BHS must share with the BHM. The range of
values is 1 to 4095. The default value is
1
.
Default Port VID
(Range 1-4094)
This is the VID that is used for untagged frames and corresponds to
the Q-Tag for 802.1Q frames (if VLAN Port Type is Q), or the C-Tag
for 802.1ad frames (if the VLAN Port Type is Q-in- Q).
