The following table describes the labels in this screen.
16.4 Port Link Aggregation
Use the Port Link Aggregation screen to configure a port trunk group and set LACP timeout.
To open the configuration screen, right-click on the switch in the Device List Panel, and click
Configuration > Ethernet Port > Port Link Aggregation. Then select a device and the
port(s) to which you want to apply this configuration.

LABEL DESCRIPTION
Ingress This feature is not supported on all models.
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 IEEE 802.1Q VLAN-unaware switch to an IEEE 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 1 and 4094.
GVRP Select the check box to permit VLAN 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 and Tag 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.
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.
