Mode
Operation

(the Default)
Enables the port to dynamically join any VLAN for which it receives an
advertisement, and allows the port to advertise other other VLANs it knows.
Block
Prevents the port from dynamically joining a VLAN that is not statically
configured on that port. The port will still forward advertisements that were
received by the switch on other ports. Block should typically be used on
ports in unsecure networks, where there is exposure to “attacks”, such as
ports where intruders can connect.
Disable
Causes the port to ignore and drop all GVRP advertisements it receives and
also prevents the port from sending any GVRP advertisements.
GVRP Enabled
(Required for Unknown
VLAN operation.)
