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.
NAME | Identifies the filter entry. |
SRC ADDR | |
| comparison. (hexadecimal format) |
SRC MASK | Bits in the MAC source address which are |
| compared. (hexadecimal format) |
DEST ADDR | |
| comparison. (hexadecimal format) |
DEST MASK | Bits in the MAC destination address used for |
| comparison. (hexadecimal format) |
MAC TYPE | |
| (hexadecimal format) |
TYPE MSK | Bits in the MAC type field used for comparison. |
| (hexadecimal format) |
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.
NAME | Identifies the filter entry. |
OFFSET | Offset from beginning of packet of where to |
| start the pattern comparison. |
PATTERN | 64 bits used for comparison. (hexadecimal |
| format) |
MASK | Bits in the pattern to be compared. |
| (hexadecimal format) |
Filter Defines /IP Filter Defines
The IP filter defines apply to any IP packet, whether it is routed or bridged. Up to 32 IP defines can be specified.
NAME | Identifies the filter entry. |
IP SRC | IP address compared to the source address. |
| (dotted decimal format) |
