Acl_Tcp_Key_Table_3
Description: This table performs the fourth stage of TCP port number look-up.
Table 95. Acl_Tcp_Key_Table_3 Register Parameters
Table 96. Acl_Tcp_Key_Table_3 Field Parameters
This fourth stage of TCP port number look-up utilizes 64 records. Three TCP port number keys are stored in each
record. The comparisons between the search argument and the keys result in a selection of one of four index val-
ues. These index values are used to address records in the next stage of the look-up.
