MAC-based VLAN Settings

This table is used to create MAC-based VLAN entries on the switch. A MAC Address can be mapped to any existing
static VLAN and multiple MAC addresses can be mapped to the same VLAN. When a static MAC-based VLAN entry
is created for a user, the traffic from this user is able to be serviced under the specified VLAN regardless of the
authentiucation function operated on the port. Therefore each entry specifies a relationship of a source MAC address
with a VLAN.

Description
These two fields allow you to specify the range of ports that will be included in the Port-based
VLAN that you are creating using the 802.1Q Port Settings window.
The Group VLAN Registration Protocol (GVRP) enables the port to dynamically become a
member of a VLAN. GVRP is Disabled by default.
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 802.1Q Port 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.
This field can be toggled using the space bar between Enabled and Disabled. Enabled
enables the port to check if the ingress port is a member port of the VLAN that the VID of an
incoming packet indicates. If it is not, the packet will be dropped. If it is, the packet will be
forwarded to the VLAN.
Disabled disables ingress filtering. Ingress Checking is Disabled by default.
This field denotes the type of frame that will be accepted by the port. The user may choose
between Tagged Only, which means only VLAN tagged frames will be accepted, and
Admit_All, which means both tagged and untagged frames will be accepted. Admit_All is
enabled by default.
