Frame Tag Operation

Basically, the default settings for tagged or untagged VLAN

will be shown automatically when you type VLAN ID/Name

and check the Active box. By the way, you can modify the tag

operation for each VLAN in this page for obtaining proper

control. Use the drop down list to choose a tag operation for

each port.

Tagged – All the computers behind that port must support

VLAN and are tagged with certain VLAN groups with specified

ID numbers.

Untagged - All the computers behind that port do not support

VLAN feature.

Note: It is recommended to group computers that do not
support VLAN feature or support VLAN feature but their
Untagged VLAN settings are checked in one port with untagged.
This device will tag proper port VLAN ID for untagged PC
respectively for making them communicating with the router.

Management Port

It can help users to communicate with router still even though

configuring the wrong setting in the 802.1Q VLAN tag. The

management port will lock index 4. We recommend that users

enable the management port to fix the fourth VLAN settings

unless users want to use the fourth VLAN and ensure the

settings are correct. You have to set Port VLAN ID for P4

previously before you check Management Port.

Port VALN ID

Type the ID for each port used for identification on VLAN.

When the tag operation for each port (representing for different

computers connected to this router) is marked by untagged, to

avoid conflict occurred, the system will apply the ID listed in

these boxes automatically for each port (P1 to P4) to ensure

proper and correct network operation.

The Simple Network Management Protocol (SNMP) is an application layer protocol that

facilitates the exchange of management information between network devices. There is a set

of protocols for managing complex networks. SNMP works by sending messages, called

protocol data units (PDUs), to different parts of a network. SNMP enables network

administrators to manage network performance, find and solve network problems, and plan for

network growth.

A SNMP-managed network consists of three key components, managed devices, agents, and

network-management systems (NMSs).

A managed device is a network node that contains an SNMP agent and that resides in a

managed network. Managed devices collect and store management information and make this
