Parameter
Description
Select
Select the IPX interface.

Note: This field is displayed in the IPX SAP Net Filter Web page, not in the Add IPX SAP Net Filter Web page.

Interface
Select the interface to which this filter will be applied to SAP packets sent and/or received on the interface.
Precedence
Specify the filter precedence (in order of importance) with 0 equal to most important.

Note: All SAP filters on the same interface must be assigned a unique filter precedence.

Net
Specify the network on which the server resides. A network number of ffffffff represents all networks.
Type
Specify the service type (in hex) that identifies the type of service the server provides. Well-known service types include:
  • Unknown (0)
  • Print Queue (3)
  • File Server (4)
  • Job Server (5)
  • Print Server (7)
  • Archive Server (9)
  • Remote Bridge Server (24)
  • Advertising Print Server (47)
  • NetWare Directory Services (278)
A value of ffff matches all service type values.
Direction
Select the direction of the filter in question. Filter choices include:
  • Inbound - Applies the filter only to SAP packets received on the interface.
  • Outbound - Applies the filter only to SAP packets sent on the interface.
  • Both - Applies the filter to SAP packets both sent and received on the interface

Default value is outbound.

Filter/Suppress
Disable whether the services matching Net and Type are filtered (inbound) or suppressed (outbound).
  • Filtered - Applies the filter only to SAP packets received (inbound direction) on the interface.
  • Suppressed - Applies the filter only to SAP packets sent (outbound direction) on the interface.
Select Disable to disable the filtering and suppression of traffic. The default is Enable.
Hops
Specify the number of routers (hops) that the packet must pass through before reaching the service(s) matched by the filter. This entry is used to override the value in the SAP packet.
Entering 0 ensures that there is no override in the transmission of data on the network.

Filtering all Services Except Netware Directory Services (NDS)

To configure your switch to filter all services except NDS a specific Interface, you must create two filters. Together, Filter 1 and Filter 2 filter services learned on the indicated interface except for NDS advertisements.

To create these filters using the Web Agent:

Filter 1

This filter ensures that all NDS packets received are not filtered on Interface Remote.

  1. In the navigation pane, expand the Routing > IPX > SAP folders, and then click Net Filters.

    2. The IPX SAP Net Filters Web page is displayed in the content pane. See Figure�183.

  2. Select CREATE. The Add IPX SAP Net Filter Web page is displayed. See Figure�184.
  3. Configure the following parameters:
    1. Select an interface name in the Interface field.
    2. Enter 0 in the Precedence field.

Note: Any filter with a Precedence of 0 will always override a filter with a precedence of 1 or higher.

    1. Enter ffffffff (which represents all networks) in the Net field.
    2. Enter 278 (which represents the type for NDS) in the Type field.
    3. Select Inbound in the Direction field.
    4. Select Disable in the Filter/Suppress field to ensure that NDS advertisements are not filtered.
    5. Enter 0 in the Hops field to ensure that there is no override in the transmission of data on the network.
  1. Click APPLY to save your changes, or CANCEL to restore previous settings.

Filter 2

Filter 2 ensures that all networks and service types are filtered for the indicated interface.

  1. In the navigation pane, expand the Routing > IPX > SAP folders, and then click Net Filters.

    2. The IPX SAP Net Filters Web page is displayed in the content pane. See Figure�183.

  2. Click CREATE to create a new filter. The Add IPX SAP Net Filter Web page is displayed. See Figure�184.
  3. Configure the following parameters:
    1. Select an interface name in the Interface field.
    2. Enter 1 in the Precedence field.
    3. Enter ffffffff (which represents all networks) in the Net field.
    4. Enter ffff (which represents all services/types) in the Type field.
    5. Select Inbound in the Direction field.
    6. Select Enable in the Filter/Suppress field.
    7. Enter 0 in the Hops field. Entering 0 ensures that there is no override in the transmission of data on the network.
  4. Click APPLY to save your changes, or CANCEL to restore previous settings.
