Memory Consistency Check Routines
Displaying OBFL Information
To display the OBFL information, use one or more of the privileged EXEC commands in Table 38-3:
For more information about using the commands in Table 38-3 and for examples of OBFL data, see the
command reference for this release.
Memory Consistency Check Routines
Note Memory consistency check routines are not supported on the Catalyst 2960-S switches.
The switch runs memory consistency check routines to detect and correct invalid ternary content
addressable memory (TCAM) table entries that can affect the performance of the switch.
If the switch cannot fix the error, it logs a system error message, specifying the TCAM space in which
the error is located:
• Unassigned space: Unassigned TCAM table entries for the current SDM template.
• Hulc Forwarding TCAM Manager (HFTM) space: Related to the Layer 2 and Layer 3 forwarding
tables.
• Hulc Quality of Service (QoS)/access control list (ACL) TCAM Manager (HQATM) space: Related
to ACL and ACL-like tables such as QoS classification and policy routing.
The output from the show platform tcam errors privileged EXEC command provides information about
the TCAM memory consistency integrity on the switch.
