Configuration > MAC-Based VLAN Settings
The 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 authentication function operated on the port. Therefore each entry specifies a
relationship of a source MAC address with a VLAN.
Figure 4.62 - Configuration > MAC-based VLAN
MAC Address:
Specify the MAC address to be reauthenticated by entering it into the MAC Address field.
VID (1-4094) / VLAN Name:
Enter the VID or VLAN name of a previously configured VLAN.
Configuration > GVRP Settings
The GVRP 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.
Figure 4.63 - Configuration > GVRP Settings
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.
