LABEL DESCRIPTIO N
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.
Ingress Check If this check box is selected, the Switch discards incoming frames on a port for VLANs that do
not include this port in its member set.
Clear this check box to disable ingress filtering.
PVID A PVID (Port VLAN ID) is a tag that adds to incoming untagged frames received on a port so
that the frames are forwarded to the VLAN group that the tag defines.
Enter a number between 1 and 4094 as the port VLAN ID.
Acceptable

dropped.
