show pxf tcam
To display version information about Ternary Content Access Memory (TCAM) devices, register values, and
cell usage by application regions, use the show pxf tcam command in privileged EXEC mode.
Syntax Description This command has no arguments or keywords.
Command Modes Privileged EXEC
Command History Release
12.2(31)SB2

Usage Guidelines The TCAM can only match binary ranges. Therefore, the router creates multiple entries, which together
have binary ranges to cover a non-binary range. This is referred to as port expansion. Another example
of entry expansion is matching the established keyword. The router implements this as two entries: one
to check for the ACK bit and the other to check if the RST bit is set.
If per access control entry (ACE) accounting is required, the router limits you to 64K ACEs for each
access control list (ACL). Otherwise, the available TCAM space defines the ACE limitation. If no
TCAM space is available, the ACE is not placed into TCAM and the router uses an ACE equivalent to
deny ip any any. When sufficient space becomes available in TCAM, you must first remove the ACL
from the interface and then reapply it to activate it.
Examples The following sample output shows the types of information that displays when you enter the show pxf
tcam command:
