Configuring IPX 15-13
The mask will also be ANDed to its corresponding field in each IPX packet as deter-
mined by IPX Filter Applications (described on
page 15-16 ). This result will be com-
pared to the AND result of the configured value and mask. If the two results match,
the filter will be applied. This process allows a number of packet field values to match
the AND result of the mask and value; for example:
Packet field =
1233
, Mask =
5678
:Packet field =
1237
, Mask =
5678

Filter Parameters
The following four tables list the IPX filter parameters. Explanations follow the tables.
Explanations of individual masks are not included below because they
were described in general on
page 15-12 .
