Bridging

Data Type

Displays the hexadecimal two-byte Þeld for the Þlter which can be used to mask out a speciÞed protocol type Þeld. Examples of protocol type are:

¥0800 = IP

¥8137 = Novell

¥0bad = Banyan

¥80f3 = AppletalkARP

Data Offset

Indicates the offset (in bytes, from the beginning of the data in the packet) where the Data Mask will be applied. The default for this Þeld is 0000 (no data offset). An example of a valid offset to enter into this Þeld is 0016 (16 bytes).

Data Mask

Displays the 64-byte overlay used to Þlter packets. The Data Mask is applied to the packet after the Þxed part of the packet, which includes Source Address, Destination Address, and Type Þelds. The Þlter applies the mask directly at the start of the data portion of the packet unless there is a Data Offset. If a Data Offset has been deÞned, the mask will apply to the data that comes after the speciÞed offset in the packet.

Receive Port(s)

Indicates the ports at which the packet must be received for Þltering information to be applied. Note that you can only immediately see one receive port per Þlter, even though you can set more than one receive port for the Þltering action to apply. The receive port Þeld can display each device bridge port, BRIM port, or Ò*Ó. The Ò*Ó indicates that a packet can be received at any port for the Þlter to apply (i.e., the port is promiscuous).

Port Filtering

forwarding Indicates the forwarding/blocking information for the Þlter at each port on the device. Note that you can only view two ports at a time.

blocking

Use the scroll bar at the top of the column to view the

 

hidden ports.

Selected Filter

This Þeld, visible at the bottom of the window, displays the number of the Þlter that is currently highlighted. The possible range is from 01-19.

Defining and Editing Filters in the Special Database

You can edit an existing Þlter or deÞne a new Þlter using the following steps:

1.Click to select the filter you wish to edit. (The filter is selected when it is highlighted. When the bridge uses the Special Database, it starts with the lowest numbered enabled filter.)
