Source MAC Address

  To reduce traffic over the network, you may want to filter certain protocols that may be sent to the unit.

IP

  If the unit does not handle IP frames, but you have IP traffic on the network, you may want to filter these frames out so the unit ignores them. Or, you can route the traffic over a specific DLCI.
  If the unit is configured to bridge or route IP frames, this filter must be OFF.

NetBIOS

  Click on this button to turn filtering ON or OFF for this protocol. If ON, NetBIOS traffic will be filtered on all routes.

Management via LLC

  This filter enables you to control LLC traffic generated by the management program. If you are managing this unit via IP, and there are no downstream units being managed via LLC, you may want to filter this type of traffic.

Source MAC Address

  This feature enables you to filter packets sent by a specific MAC address.

Input IP Filters

  This feature enables you to discard or forward incoming IP traffic according to specified parameters.

IPX

  If the unit does not handle IPX frames, but you have IPX traffic on the network, you may want to filter these frames out so the unit ignores them. Or, you can route the traffic over a specific DLCI.
  If the unit is configured to bridge or route IPX frames, this filter must be OFF.

SNA/LLC2

  If the unit does not handle SNA/LLC2 frames, but you have SNA/LLC2 traffic on the network, you may want to filter these frames out so the unit ignores them. Or, you can route the traffic over a specific DLCI.

Other Frame Types

  Click on this button to turn filtering ON or OFF for this protocol. If ON, traffic, other than the ones mentioned above, will be filtered on all routes.

ARP Filter

  This type of filtering enables you to select the interfaces through which ARP packets are forwarded or discarded.

Output IP Filter

  This feature enables you to discard or forward outgoing IP traffic according to specified parameters.
