Filter Defines
The TA 850 can filter packets based on certain parameters within the packet. The method used by the
TA 850 allows the highest flexibility for defining filters and assigning them to a PVC. The filters are set
up in two steps: (1) defining the packet types, and (2) adding them to a list under the PVC. This menu is
used to define the individual filter defines based on packet type.
Filter Defines /MAC Filter Defines
The MAC filter is applied to bridge packets only. Bridge packets which are forwarded by the bridge
functionality of the TA 850 are defined here. Up to 32 MAC defines can be specified.
Filter Defines /Pattern Filter Defines
The pattern filter is applied to bridge packets only. That is any packet which is forwarded by the bridge
functionality of the TA 850. Up to 32 pattern defines can be specified.
