8.6 Port-based VLAN Setup

Port-based VLANs are VLANs where the packet forwarding decision is based on the
destination MAC address and its associated port.
Port-based VLANs require allowed outgoing ports to be defined for each port. Therefore, if
you wish to allow two subscriber ports to talk to each other, for example, between conference
rooms in a hotel, you must define the egress (an egress port is an outgoing port, that is, a port
through which a data packet leaves) for both ports.
Port-based VLANs are specific only to the switch on which they were created.

DESCRIPTION
GVRP (GARP VLAN Registration Protocol) is a registration protocol that defines a
way for switches to register necessary VLAN members on ports across the
network.
Select this check box to permit VLAN groups beyond the local switch.
Port Isolation allows each port to communicate only with the CPU management
port and the dual personality GbE interfaces but not communicate with each other.
This option is the most limiting but also the most secure.
This field displays the port number.
Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this
row first to set the common settings and then make adjustments on a port-by-port
basis.
Note: Changes in this row are copied to all the ports as soon as you
make them.
If this check box is selected for a port, the Switch discards incoming frames for
VLANs that do not include this port in its member set.
Clear this check box to disable ingress filtering.
Enter a number between 1and 4094 as the port VLAN ID.
Select this check box to allow GVRP on this port.
Specify the type of frames allowed on a port. Choices are All, Tag Only and Untag
Only.
Select All from the drop-down list box to accept all untagged or tagged frames on
this port. This is the default setting.
Select Tag Only to accept only tagged frames on this port. All untagged frames will
be dropped.
Select Untag Only to accept only untagged frames on this port. All tagged frames
will be dropped.
Enable VLAN Trunking on ports connected to other switches or routers (but not
ports directly connected to end users) to allow frames belonging to unknown VLAN
groups to pass through the Switch.
Click Apply to save your changes to the Switch's run-time memory. The Switch
loses these changes if it is turned off or loses power, so use the Save link on the
top navigation panel to save your changes to the non-volatile memory when you
are done configuring.
Click Cancel to reset the fields.
