9.6 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.
"
When you activate port-based VLAN, the Switch uses a default VLAN ID of 1.
You cannot change it.
* 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.
PVID Enter a number between 1and 4094 as the port VLAN ID.
GVRP Select this check box to allow GVRP on this port.
Acceptable
Frame Type
Specify the type of frames allowed on a port. Choices are All and Tag 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.
VLAN Trunking 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.
Isolation Select this to allows this port to communicate only with the CPU management port
and the ports on which the isolation feature is not enabled.
Apply 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.
Cancel Click Cancel to begin configuring this screen afresh.
