9.8 Subnet Based VLANs

Subnet based VLANs allow you to group traffic into logical VLANs based on the source IP subnet you
specify. When a frame is received on a port, the Switch checks if a tag is added already and the IP

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.
This field appears only in stacking mode. Click the drop-down list to choose the slot number of
the Switch in a stack.
This field displays the port number of the Switch. In stacking mode, the first number represents
the slot ID and the second is the port number. Please note that the default stacking ports (the
last two ports of your Switch) cannot be configured. They are reserved for stacking only.
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, the Switch discards incoming frames on a port for VLANs that do
not include this port in its member set.
Clear this check box to disable ingress filtering.
A PVID (Port VLAN ID) is a tag that adds to incoming untagged frames received on a port so
that the frames are forwarded to the VLAN group that the tag defines.
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.
Note: When the Switch is in stacking mode and the master Switch has VLAN1, all
other ports will be configured to untagged port.
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.
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.
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 begin configuring this screen afresh.
