Use this tab to control and optimize network performance.

Ethernet Protocol Filter

Filter Operation. If set to Allow, only the enabled Ethernet Protocols listed in the Filter Table will be active. If set to Deny, only the enabled Ethernet Protocols listed in the Filter Table will be inactive.

Ethernet Protocol Filter Table

This table is pre-populated, however, you may add specific protocols.

To add an entry, click Add, and then specify the Protocol Number and a protocol name in the Comment field.

  • Protocol Number. Enter the protocol number.
  • Protocol Name. Enter related information, typically the protocol name.
  • Status. Select Enable, Disable, or Delete.

To edit or delete an entry, click Edit. Edit the information, or select Enable, Disable, or Delete from the Status pull-down menu.

Static MAC Address Filter

You can use the Static MAC Address filter to optimize the performance of a wireless (and wired) network. The filter is an advanced Bridge setup parameter for AP-3 devices. It enables you to deny data traffic between two specific devices via the wireless interface(s) of the AP-3 bridge.

For example, to prevent redundant traffic from being transmitted over the wireless network, you could deny traffic between two particular servers, identified by their MAC Address and their location as perceived by the AP-3 (on the `wired' or wireless' port of the bridge).

In most situations, however, it will be easier to control redundant traffic via other filtering options, such as Protocol Filtering.

  • Wired MAC Address. Enter the MAC Address of the device.
  • Wired Mask. Enter the Wired Mask value.
  • Wireless MAC Address.Enter the MAC Address of the device.
  • Wireless Mask. Enter the Wireless Mask value
  • Comment. Enter related information.

Spanning Tree

An advanced Bridge setup option for complex network topologies that enables you to enhance data traffic efficiency and eliminate the possibility of data loops. With the spanning tree algorithm, all bridges on the LAN exchange special configuration messages that allow them to:

  • Elect a single bridge in connected LAN segments to be the root bridge.
  • Calculate the distance of the shortest path to the Root Bridge.
  • Elect a `Designated Bridge' in each LAN segment to forward packets.
  • between that LAN segment and the Root Bridge.
  • Select a `Root Port' among all ports of the bridge unit.

The spanning tree algorithm enables bridges to calculate a loop-free subset of the LAN topology that provides the most efficient level of connectivity between every pair of physically connected Local Area Network segments.

If the `shortest data path' fails, (for example as a result of a physical breakdown), the Spanning Tree will automatically rebuild the topology within the confines of the available bridged LAN components. These settings should be left at the default values.

  • Spanning Tree Status. Select Enable to allow Spanning Tree operations, or select Disable to prevent Spanning tree operations. Default is Enable.
  • Bridge Priority. Enter the Bridge Priority value. Default is 0. The bridge units must determine which unit is the root bridge amongst themselves.
  • Max Age. Enter the maximum age allowed. Default is 2000 seconds.
  • Hello Time. Enter the Hello Time value. Default is 200 seconds.
  • Forward Delay. Enter the Forward Delay value. Default is 1500 seconds.

Storm Threshold

An advanced Bridge setup option that you can use to protect the network against data overload by:

  • Specifying a maximum number of frames per second as received from a single network device (identified by its MAC address).
  • Specifying an absolute maximum number of messages per port.

The `Storm Threshold' parameters allow you to specify a set of thresholds for each port of the AP-3, identifying separate values for the number of broadcast messages/second and Multicast messages/second.

When the number of frames for a port or identified station exceeds the maximum value per second, the AP-3 will ignore all subsequent messages issued by the particular network device, or ignore all messages of that type.

  • Address Threshold. Enter the maximum allowed number of packets per second.
  • Interface 1 Threshold. Enter the maximum allowed number of packets per second.
  • Interface 2 Threshold. Enter the maximum allowed number of packets per second.
  • Interface 3 Threshold. Enter the maximum allowed number of packets per second.

Advanced Filtering

  • Proxy ARP Status. Select Enable to allow proxy Address Resolution Protocol, or Disable to prevent proxy Address Resolution Protocol.
  • IP/ARP Filtering Status. Select Enable to allow filtering, or Disable to prevent filtering.
  • IP/ARP Filtering Address. Enter the IP Address.
  • IP/ARP Subnet Mask. Enter the Subnet Mask.

The following advanced filtering protocols can filter in the wireless-to-Ethernet direction, the Ethernet-to-wireless direction, or both directions. Use the Status field to enable or disable the filter.

  • Deny IPX RIP
  • Deny IPX SAP
  • Deny IPX LSP
  • Deny IPX Broadcast
  • Deny IPX Multicasts

SpectraLink VoIP

SpectraLink is a third part provider of wireless phone sets operating on the 2.4 GHz band. This feature is used allow voice packets to be transmitted over the 802.11 wireless LAN protocol.

  • SpectraLink VoIP Status. Select Enable to allow SpectraLink VoIP operation, or Disable to prevent SpectraLink VoIP operation.
