TCP/UDP Port Filters
The IE-WL-VL-AP-BR-CL’s TCP/UDP port filter is a policy-based filter that can allow or filter out TCP/UDP-based
packets with a specified source or destination port.
The IE-WL-VL-AP-BR-CL provides 32 entities for setting the range of source/destination ports of a specific
protocol. In addition to selecting TCP or UDP protocol, you can set either the source port, destination port, or
both. The end port can be left empty if only a single port is specified. Of course, the end port cannot be larger
than the start port.
The Application name is a text string that describes the corresponding entity with up to 31 characters.
Remember to check the Active check box for each entity to activate the setting.

Only the packets fitting the entities on list can be allowed.
Drop

Any packet fitting the entities on list will be denied.
ATTENTION
Be careful when you enable the filter function:
Drop + “no entity on list is activated” = all packets are allowed
Accept + “no entity on list is activated” = all packets are denied
RSTP Settings (Master or Slave Mode Only)
The IE-WL-VL-AP-BR-CL supports IEEE 802.1D for Spanning Tree Protocol (STP) and IEEE 802.1w for Rapid
STP standards. In addition to eliminating unexpected path looping, STP/RSTP can provide a backup path
recovery if a wired/ wireless path fails accidentally. The reliability and availability can increase because this
fail-over function.
IE-WL-VL-AP-BR-CL’s STP/RSTP feature is disabled by default. To be completely effective, you must enable
RSTP/STP on every IE-WL-VL-AP-BR-CL connected to your network. If IE-WL-VL-AP-BR-CL plays a Slave role,
which is connected to a device (PLC, RTU, etc.) as opposed to network switch equipment, it is not necessary to
enable STP/RSTP. The reason is that it will cause unnecessary negotiation. IE-WL-VL-AP-BR-CLs support
STP/RSTP in Master or Slave mode only.
The following figures indicate which Spanning Tree Protocol parameters can be configured. A more detailed
explanation of each parameter is given below the figure.
