This section of the sample command output indicates the memory usage of the MiniACLs in the router.
All of the rows state about the same thing. To determine the actual number of MiniACLs in play, divide
the memory used in any of blocks 1 to 10 by 256, or blocks 11 to 14 by 16.
MiniACL XCM Tables:
Block Use Memory Used %Free
0 IP Src 1 768 99
1 IP Src 2 768 99
2 IP Src 3 768 99
3 IP Src 4 768 99
4 IP Dest 1 768 99
5 IP Dest 2 768 99
6 IP Dest 3 768 99
7 IP Dest 4 768 99
8 ToS 768 99

10 TCP Flags/Fragment 768 99
11 Source Port 1 48 99
12 Source Port 2 48 99
13 Destination Port 2 48 99

The following describes the information displayed in the last section of the sample output from the show
pxf cpu access-lists security command:
Available MiniACL count = 8191

Table 45, Part 4, describes the significant fields shown in the display.
PRE2 and PRE3 Security ACLs Examples (Cisco 10000 Series Router)
This section compares the output from the show pxf cpu access-lists security command when issued on
the PRE2 and PRE3.
For the PRE2, the following sample output displays VMR (value, plus a mask and result) data for the
ACL named ICMP_IGMP_MATCH:
