VLAN, Tag All and Untag All, and possible configuration are as
follows:

Untag Port VLAN : means that all VLAN identifiers will
remain as it ingress at the switch except VLAN identifiers
equal to the Port VLAN number. If VLAN Identifier (VID) of
the frame at the egressing queue is equal to Port VLAN,
switch will remove VID and frame will be forwarded as
untagged frame. Other VID numbers are not affected and
are forwarded with their VLAN identifier tag;

Tag All: means that all frames at the egressing queue will
be forwarded as tagged frame, including frames that had
entered at the switch as untagged;
 Untag All : means that all frames at the egressing queue
will be forwarded as untagged frame, including frames
that had entered at the switch as tagged;
o
Allowed VLANs: indicate the VLANs a port can become a member
of. Access ports have this field disabled, and these ports can only
be member of the Allowed Access VLANs identifier VLAN. Trunk and
Hybrid mode ports can be member of many VLAN, and this field
specifies all VLAN that these port modes can be member of.
Allowed values are the VLAN range values (from 1 to 4,095). It is
possible to insert specific VLAN identifiers separated by comma (for
instance, 1,2,10,40), a range of VLAN identifiers using the “ - “
character (for instance, 10-40), and a meshed specific and range
VLAN identifiers (for instance, 1,2,10-40). By default, Trunk and
Hybrid ports are members of all VLAN range (1 - 4,095);
o
Forbidden VLANs : indicate the VLAN a port cannot become a
member of. Access, Trunk and Hybrid mode ports can be
configured to refuse many VLAN identifier traffic, and this field
specifies all VLAN that these port modes cannot be member of.
Allowed values are the VLAN range values (from 1 to 4,095). It is
possible to insert specific VLAN identifiers separated by comma (for
instance, 1,2,10,40), a range of
VLAN identifiers using the “ - “
character (for instance, 10-40), and a meshed specific and range
VLAN identifiers (for instance, 1,2,10-40). By default, all ports have
this field empty, meaning that there is no VLAN restriction.
After one of the configurations described before is changed, there are buttons that
allows the user to save or discard the configurations.
o
Save : save configuration at the Running Config;
o
Reset : undo changes made locally at the Running Config.
