The following table describes the labels in this screen.
Table 7-3 802.1Q VLAN Port Settings
LABEL DESCRIPTION
GVRP GVRP (GARP VLAN Registration Protocol) is a registration protocol that defines a way for
switches to dynamically register necessary VLAN members on ports across the network.
Select this check box to permit VLAN groups beyond the local switch.
Port Isolation Port Isolation allows each port (1 to 26) to communicate with the CPU port, uplink ports and
stacking ports but not communicate with each other. This option is the most limiting but also the
most secure.
Port This field displays the port numbers.
Ingress Check If this check box is selected for a port, the device discards incoming frames for VLANs that do
not include this port in its member set.
PVID Each port on the switch is capable of passing tagged or untagged frames. To forward a frame
from an 802.1Q VLAN-unaware switch to an 802.1Q VLAN-aware switch, the switch first
decides where to forward the frame, and then inserts a VLAN tag reflecting the default ingress
port's VLAN ID, the PVID. The default PVID is VLAN 1 for all ports, but this can be changed to
any number between 0 and 4094.
GVRP Select this check box to permit VLANs groups beyond the local switch on this port. 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.
Acceptable
Frame Type Specify the type of frames allowed on a port. Choices are All , Tag Only and Untag Only .
Select All to accept all frames with 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 are dropped.
Select Untag Only to accept only untagged frames on this port. All tagged frames are 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.

7.2.2 802.1Q Static VLAN
You can dynamically have a port join a VLAN group using GVRP, permanently assign a port to be a member of a
VLAN group or prohibit a port from joining a VLAN group in this screen. Click
