LABEL DESCRIPTION
GVRP 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 Port Isolation allows each port to communicate only with the CPU management
port and the Gigabit uplink ports but not communicate with each other. This option
is the most limiting but also the most secure.
Ingress Check Select this check box to activate ingress filtering on the Switch.
Clear this check box to disable ingress filtering the Switch.
Port 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.
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.
