Table 71. Acl_Ip_Key_Table_8 Field Parameters
This final stage of IP address look-up operates only on IPv6 addresses. This stage utilizes 256 records of two IPv6
addresses each. Each record contains three possible sets of result values.
ipv6_key_{0..1}[127:0]
ip_src_addr_index_{0..2}[8:0]
ip_src_flow_id_{0..2}[2:0]
ip_dest_addr_index_{0..2}[8:0]
ip_dest_flow_id_{0..2}[2:0]

Parameters
Offset = 0.0
A 128-bit IPv6 address value. This value is com-
pared against the search argument. The result of
this comparison is used to select one of two
index values for use in the next stage of the look-
up.
This value is used in conjunction with the ACL
index to select one of 1,024 ACE maps for the
corresponding IP source address.
This field identifies a flow associated with the
matching IP source address.
