Acl_Tcp_Key_Table_1
Description: This table performs the second stage of TCP port number look-up.
Table 91. Acl_Tcp_Key_Table_1 Register Parameters
Table 92. Acl_Tcp_Key_Table_1 Field Parameters
This second stage of TCP port number look-up utilizes four 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
values. These index values are used to address records in the next stage of the look-up.
