The following sample output describes the information displayed in the next section of the command
output from the show pxf cpu access-lists security command. There are 16 banks of XCM in each PXF
column. This output section shows the usage level of each bank.

Table 45, Part 3, describes the significant fields shown in the display.
Ta b l e 45, Part 2 show pxf cpu access-lists security Field Descriptions
Field Description
Block Indicates the block number.
Use Describes the IP packet field that is being matched.
Rows An indication of where the largest variety of values are in use
in the ACLs that are being applied. In the output, 12/128
means that there are 12 different values of significance in the
field. If there are other rules added and the value exceeds 128,
more memory will be needed to accommodate the new rules.
Columns An indication of the number of TurboACLs in PXF memory.
In the output, 1/32 means there is only one TurboACL in PXF
memory. If there are more than 31 added, another chunk of
memory is needed to accommodate the new ACLs.
Memory used Displays the total amount of memory used for this particular
lookup table.
Ta b l e 45, Part 3 show pxf cpu access-lists security Field Descriptions
Field Description
Banknum The block of memory used for this particular lookup table.
Heapsize The total amount of memory, in bytes, allocated for this
block.
Freesize The amount of memory, in bytes, that is currently available
for use by this block of memory.
%Free The percentage of memory that is free and available for use for
this block of memory. When the %Free drops to 0, the router
cannot hold any more ACLs in PXF memory, and any new
ACL will not pass traffic.
