FM Messages Chapter 2 Messages and Recovery Procedures FM-4 Error Message %FM-2-TCP_FLAG_HW_EXCEPTION: No VLOUs available for TCP FLAGs for interface [chars] in [chars] direction: all features on the interface for the specified direction will be NOT effective Explanation No VLOUs are available for TCP flags. This condition cannot be handled in the software for all the features configured on the interface. A message is printed on the console to notify the user of this error condition. Because there are no features that the software can handle, the system will program an entry to permit all traffic. Recommended Action The hardware TCAM can handle up to 9 logical operations per interface and up to 64 logical operations in total. To recover from this error, recompute the ACLs for the features that cannot be handled in the software (for example, VACLs) to move entries using TCP flags before others entries are moved and to minimize the usage of TCP flags. Error Message %FM-2-TCP_FLAG_SW_EXCEPTION: No VLOUs available for TCP FLAGs on interface [chars] in [chars] direction: traffic will be software switched, features which are NOT processable in software will be NOT effective Explanation No VLOUs are available for TCP flags. This condition cannot be handled in the software for some features configured on the interface. A message is printed on the console to notify the user of this error condition. Because there are some features that can be handled in the software (for example, VACLs and RACLs), an exception entry and traffic on this interface will be sent to the software. Recommended Action The hardware TCAM can handle up to 9 logical operations per interface and up to 64 logical operations in total. To recover from this error, recompute the ACLs for the features that cannot be handled in the software (for example, VACLs) to move entries using TCP flags before others entries are moved and to minimize the usage of TCP flags. Error Message %FM-4-FLOWMASK_REDUCED: Features configured on interface [chars] have conflicting flowmask requirements, some features may work in software Explanation The configured features for this interface have a flow mask conflict. The traffic on this interface and the interfaces sharing the TCAM label with this interface will be sent to the software. Recommended Action Redefine and reapply or unconfigure one or more features to avoid the conflict. Error Message %FM-4-L2_DYN_TCAM_EXCEPTION: Failed to install Dynamic TCAM entry to filter Layer 2 traffic, error status: [dec], host IP address: [IP_address], interface: [chars] Explanation There is an error in installing the per-user policies in the Dynamic TCAM region to filter Layer 2 traffic. The TCAM might be full. As a result, host ingress traffic will be subjected to the default interface ACL. Recommended Action Attempt to free up TCAM resources. 2-138 Catalyst Supervisor Engine 32 PISA Cisco IOS System Message Guide, Release 12.2ZY OL-11469-02
