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
