for the port.
Untagged VLAN ID
If Tx Tag is overridden in the port and is set to UVID (Untagged VLAN ID),
then this field will show the VLAN ID the user wants to untag on egress.
Conflicts
Two users may have conflicting requirements to a port's configuration.
For instance, one user may require all frames to be tagged on egress
while another requires all frames to be untagged on egress.
Since both users cannot win, this gives rise to a conflict, which is solved
in a prioritized way. The Administrator has the least priority. Other
software modules are prioritized according to their position in the
drop-down list: The higher in the list, the higher priority.
If conflicts exist, it will be displayed as "Yes" for the "Combined" user and
the offending software module.
The "Combined" user reflects what is actually configured in hardware.
3.7.2.4 Private VLAN Membership
The private VLAN membership configuration for the switch can be monitored and modified from this
page. Private VLANs can be added or deleted and port members of each private VLAN can also be
added or removed.
Private VLANs are based on the source port mask and there are no connections to VLANs. This
means that VLAN IDs and private VLAN IDs can be identical.
A port must be a member of both a VLAN and a private VLAN to be able to forward packets. By
default, all ports are VLAN unaware and members of VLAN 1 and private VLAN 1.
A VLAN-unaware port can only be a member of one VLAN, but it can be a member of multiple private
VLANs.
Press the button
Add New Private VLAN
to add a new private VLAN ID. An empty row is added to
the table and the private VLAN can be configured as needed. The allowed range for a private VLAN
ID is the same as the switch port number range. Any values outside this range are not accepted and
a warning message appears.
The
Delete
button can be used to undo the addition of new private VLANs.
