Token Ring Special Filter Database Window

At the Token Ring Special Filter Database window, Figure 4-14, you can view a list of the special Þlters for the selected bridge. There are 19 available Þlters in the Token Ring Special Filter Database. You can not add any additional Þlters. You can view Þve of these Þlters at a time in the Token Ring Special Filter Database window. Use the scroll bars to view the other fourteen Þlters.

When you Þrst open the window, all Þlters will be undeÞned. For each Þeld, bytes will be initialized with match any characters (xx) for each digit. Any hexadecimal byte will be accepted as valid for the corresponding wildcard (xx) characters. For example, a Source Address Þlter deÞned as Òxx-xx-xx-xx-bf-coÓ will pass the Þrst four bytes of a frameÕs source address unconditionally, but the last two bytes must match the Òbf-coÓ Þlter.
