Acl_Ip_Addr_Ace_Map_Table
Description: This table converts ACE map index values into ACE maps.
Table 52. Acl_Ip_Addr_Ace_Map_Table System Parameters
Table 53. Acl_Ip_Addr_Ace_Map_Table Field Parameters
This table is addressed by Acl_Ip_Addr_Ace_Map_Index_Table.ip_addr_ace_map_index[9:0] and
returns the 64-bit ACE map value for the associated IP address. An ACE map is a vector that identifies all of the
ACEs for which the associated IP address generates a match.
The following figure shows where this table fits in the ACL processing pipeline.
