Chapter 8 VLAN 85
The following table describes the labels in this screen.
8.6 Port-based VLAN Setup
Port-based VLANs are VLANs where the packet forwarding decision is based on the
destination MAC address and its associated port.
Port-based VLANs require allowed outgoing ports to be defined for each port. Therefore, if
you wish to allow two subscriber ports to talk to each other, for example, between conference
rooms in a hotel, you must define the egress (an egress port is an outgoing port, that is, a port
through which a data packet leaves) for both ports.
Port-based VLANs are specific only to the switch on which they were created.
Note: When you activate port-based VLAN, the switch uses a default VLAN ID of 1.
You cannot change it.
In screens (such as IP Setup and Filtering ) that require a VID, you must enter
1 as the VID.

LABEL DESCRIPTION
GVRP 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.
Select this check box to permit VLAN groups beyond the local switch.
Port Isolation Port Isolation allows each port (1 to 26) to communicate only with the CPU
management port but not communicate with each other. All incoming ports are
selected while only the CPU outgoing port is selected. This option is the most
limiting but also the most secure.
Port This field displays the port number.
Ingress Check 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.
Clear this check box to disable ingress filtering.
PVID Enter a number between 1and 4094 as the port VLAN ID.
GVRP Select this check box to allow GVRP on this port.
Acceptable Frame
Type
Specify the type of frames allowed on a port. Choices are All and Tag Only .
Select All from the drop-down list box to accept all 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 will
be 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.
