VLAN Management
A VLAN is a group of ports that can be located anywhere
in the network, but communicate as though they belong
to the same physical segment .
in the network, but communicate as though they belong
to the same physical segment .
VLANs help to simplify network management by allowing
you to move devices to a new VLAN without having
to change any physical connections . VLANs can be
easily organized to reflect departmental groups (such
as Marketing or R&D), usage groups (such as e-mail), or
multicast groups (used for multimedia applications such
as videoconferencing) . You can create up to 256 VLANs on
the Switch .

You can configure VLAN behavior for specific interfaces,

(PVID), and ingress filtering .
including the mode, accepted frame type, VLAN identifier
(PVID), and ingress filtering .
Mode
Indicates VLAN membership mode for an interface .
(Default: General)
Access
Is the default setting for all ports . The port is a
member of a single, untagged VLAN .
Trunk
Specifies a port as an end-point for a VLAN
trunk . A trunk is a direct link between two switches,
so the port transmits tagged frames that identify the
source VLAN . Note that frames belonging to the port’s
default VLAN (that is, associated with the PVID) are also
transmitted as tagged frames .

default VLAN (that is, associated with the PVID) are also
transmitted as tagged frames .
General
Specifies a hybrid VLAN interface . The port
may transmit tagged or untagged frames .
Acceptable Frame Type
Sets the interface to accept all
frame types, including tagged or untagged frames, or
only tagged frames . When set to receive all frame types,
any received frames that are untagged are assigned to the
default VLAN . (Options: All, Tagged, Active; Default: All)
only tagged frames . When set to receive all frame types,
any received frames that are untagged are assigned to the
default VLAN . (Options: All, Tagged, Active; Default: All)
PVID (Port VLAN dentfer)
VLAN ID assigned to
untagged frames received on the interface . (Default: 1)
If an interface is not a member of VLAN 1 and you assign
its PVID to this VLAN, the interface will automatically
be added to VLAN 1 as an untagged member . For all
other VLANs, an interface must first be configured as an
untagged member before you can assign its PVID to that
group .
