5 Configuration
Join Time (100-100000): Indicates the time in milliseconds that PDUs are transmitted. The default value is
200ms.
Leave Time (100-100000): Indicates the amount of time in milliseconds that the device waits before leaving
its GARP state. The leave time is activated by a leave all time message sent/received, and cancelled by the
Join message. The default value is 600ms.
Leave_All Time (100-100000): Used to confirm the port within the VLAN. The time in milliseconds between
messages sent. The default value is 10000ms.

VLAN > GVRP > GVRP Port Settings
The GVRP Port Settings page allows user to determine whether the Switch will share its VLAN configuration
information with other GARP VLAN Registration Protocol (GVRP) enabled switches. In addition, Ingress
Checking can be used to limit traffic by filtering incoming packets whose PVID does not match the PVID of
the port. Results can be seen in the table under the configuration settings, as seen below.
From Port/To Port: These two fields allow user to specify the range of ports that will be included in the Port-
based VLAN that user is creating using the 802.1Q Port Settings page.
PVID(1-4094): The read-only field in the 802.1Q Port Table shows the current PVID assignment for each
port, which may be manually assigned to a VLAN when created in the Settings table. The Switch's default is
to assign all ports to the default VLAN with a VID of 1. The PVID is used by the port to tag outgoing,
untagged packets, and to make filtering decisions about incoming packets. If the port is specified to accept
only tagged frames - as tagging, and an untagged packet is forwarded to the port for transmission, the port
will add an 802.1Q tag using the PVID to write the VID in the tag. When the packet arrives at its destination,
the receiving device will use the PVID to make VLAN forwarding decisions. If the port receives a packet, and
Ingress filtering is enabled, the port will compare the VID of the incoming packet to its PVID. If the two are
unequal, the port will drop the packet. If the two are equal, the port will receive the packet.
NOTE: Leave time must be greater than or equal
to three times the join time.
Leave_all time must be greater than the
leave time.
