This field defines the bits in the received frame, starting at the specified offset, that should be tested against the contents of the value field. Only the bits which have a value of B′1′ in the mask will be tested.

∙Logical Operator

The following operators can be used for testing:

−Equal

−Not_equal

−Less_than

−Greater_than

∙Value

This field specifies the 32-bit unsigned value against which the contents of a frame starting at the specified offset should be compared.

When you install the Multiprotocol Interconnect module (or after a cold start), the custom filter test table has 64 dummy entries defined for it. To define a test, select the Modify Entry parameter on this panel. A pop up window will be displayed, which allows you to define the parameters described above. Once the entry is defined, select Set Entry to confirm or Cancel to abandon the operation. An example of a Custom Filter Test Table entry is shown in Table 39.

This example enables the Multiprotocol Interconnect module to test the contents of two bytes, starting at offset 12 from the beginning of the MAC address against the value X′5DC′ (1500 decimal). In Ethernet frames, this is called the ″length″ or ″type″ field. In Ethernet V2 frames, this field always contains a value higher than 1500, whereas 802.3 frames always contain a value less than 1500. Therefore, this entry allows you to check and see if the frame is an 802.3 or Ethernet V2 frame.

2.Once you have defined all the desired tests, you must define the tests that should be performed on each port, using the Custom Filter Statement Table. Note that there is one Custom Filter Statement Table for each port.

To define entries in the Custom Filter Statement Table, select Custom Filter Statement Table from the Bridge menu. An example of this table is shown in Figure 159 on page 277.
