Status:
Enable/Disable the GVRP feature for the port. The port type
should be set to TRUNK before enabling the GVRP feature.
LeaveAll Timer:
Once the LeaveAll Timer is set, the port with GVRP enabled can
send a LeaveAll message after the timer times out, so that other
GARP ports can re-register all the attribute information. After that,
the LeaveAll timer will start to begin a new cycle. The LeaveAll
Timer ranges from 200 to 6000 centiseconds.
Join Timer:
To guarantee the transmission of the Join messages, a GARP port
sends each Join message two times. The Join Timer is used to
define the interval between the two sending operations of each
Join message. The Join Timer ranges from 10 to 100
centiseconds.
Leave Timer:
Once the Leave Timer is set, the GARP port receiving a Leave
message will start its Leave timer, and deregister the attribute
information if it does not receive a Join message again before the
timer times out. The Leave Timer ranges from 20 to 600
centiseconds.
LAG:
Displays the LAG to which the port belongs.
Note:
LeaveAll Timer >= 10* Leave Timer, Leave Timer >= 2*Join Timer.

Private VLAN
Private VLANs, designed to save VLAN resources of uplink devices and decrease broadcast,
are sets of VLAN pairs that share a common primary identifier. To guarantee user information
security, the ease with which to manage and account traffic for service providers, in campus
network, service providers usually require that each individual user is Layer-2 separated. VLAN
feature can solve this problem. However, as stipulated by IEEE 802.1Q protocol, a device can
only support up to 4094 VLANs. If a service provider assigns one VLAN per user, the VLANs will
be far from enough; as a result, the number of users this service provider can support is limited.
