Filtering Traffic by Protocols
You can configure the AP to NOT forward specific protocol traffic to the wireless network.
This could reduce unnecessary traffic and increase the network response time. However,
filtering the wrong protocols can negatively affect the operation of the network. When
solving network problems, you should clear all filters.
To select the protocol to filter using the AP Manager, perform the following steps:
1. Click on the Filtering button in the main window to access the Filtering Dialog Box.
2. Click on the Protocol tab.
3. For a RoamAbout R2, select the slot (1 or 2).
4. Select the protocols to filter, as described in Table 5-1. Only the filters supported by
the selected AP are available. The filters are enabled when they are checked, meaning
that traffic of the protocol specified is NOT forwarded by the AP.
5. Click OK to implement your change. The AP does not need to be reset.
If you select one or more protocols, the AP Manager applies those changes to ALL of the
APs selected in the Managed List field in the main window. The AP Manager prompts you
for confirmation before changing the parameters on multiple APs.
Table 5-1: Protocols to Filter
Protocol Description
IP V4 Does not forward IP version 4 packets carried in Ethernet V2 frames or IEEE 802.3
frames with Logical Link Control (LLC)/Subnetwork Access Protocol (SNAP)
headers. Also, the filter does not forward Address Resolution Protocol (ARP)
packets carried in Ethernet V2 frames.
IP is used in many environments, most notably UNIX networks and the Internet.
When enabled, IP, TCP/IP, and UDP/IP packets are not forwarded. This filter
should NOT be set if the AP is to be managed from a wireless node.
IPX Ethernet II Does not forward IPX packets carried in Ethernet V2 frames. Used primarily in
NetWare environments.
IPX - 802.2 Does not forward IPX packets carried in IEEE 802.3 frames with LLC headers.
Used primarily in NetWare environments.
NetBEUI Does not forward NetBEUI packets. Used primarily in Microsoft native
networking.
