Action If the message recurs, copy the error message exactly as it appears on the console or in the system log, call your Cisco technical support representative, and provide the representative with the gathered information.

Feature Manager Messages

This section contains the feature manager error messages. The feature manager software module manages access control lists (ACLs). Most messages in this section are the result of a switch memory shortage, which includes hardware memory such as the forwarding table (TCAM) and label space versus CPU memory. Both kinds of memory shortages are described.

 FM-1-INIT: Feature Manager subsystem initialization failure.

Explanation    This message means that the feature manager subsystem failed to initialize. The most likely cause is insufficient memory at initialization. Either the hardware has failed, or the wrong image is installed.

Action Replace the failing hardware, or obtain the correct IOS image for this platform.

 FM-1-INITLABEL: Special initialization of label [dec] failed.

Explanation    Initialization of the access list hardware failed. Prioritization of routing protocol packets above other kinds of packets might not occur on some VLANs or routed ports.

Action Reduce other system activity to ease the CPU demands. If the conditions warrant, upgrade to a larger memory configuration.

 FM-2-NOSB: Cannot create subblock for interface [chars].

Explanation    This message means that the feature manager was unable to save per-interface information needed for its correct operation. Some per-interface features, such as access groups or VLAN maps, will not be correctly configured. [chars] is the interface name.

Action Use a less complicated configuration that requires less CPU DRAM.

 FM-2-NOVLB, FM, LOG_CRIT, 0, Cannot create memory block for VLAN [dec].

Explanation    This message means that the feature manager was unable to save per-VLAN information needed for its correct operation. Some per-interface features, such as access groups or VLAN maps, will not be correctly configured. [dec] represents the VLAN number.

Action Use a less complicated configuration that requires less CPU DRAM.

 FM-2-NOVMR: Cannot create VMR data structures for access list [chars].

Explanation    This message means that the feature manager could not allocate the data structures needed to describe an ACL in a form that can be loaded into hardware. This error is probably caused by a lack of available CPU DRAM. [chars] is the access-list name.

Action Use a less complicated configuration that requires less memory.

 FM-3-AUGMENTFAIL: Augmenting of access-map [chars] on [chars] label [dec] failed.

Explanation    This message means that the system ran out of CPU DRAM when attempting to merge internally required elements with the configured access maps. The first [chars] is the access-map name, and the second [chars] is the direction in which the map was applied (input or output). [dec] is the label number.

Action Reduce other system activity to ease the memory demands. If the conditions warrant, upgrade to a larger memory configuration.

 FM-3-GOTLABEL: Got label for [chars].

Explanation    This message means that the feature manager is able to allocate a hardware label for the interface. The interface needed a label before, but no label was available. [chars] is the label.

Action No action is required. (This message pairs with the FM-3-NOLABEL message and means that the previous error condition has rectified itself.)

 FM-3-GOTVLABEL: Got label for VLAN [dec].

Explanation    This message means that the feature manager is able to allocate a hardware label for the VLAN. The VLAN needed a label before, but no label was available. [dec] is the VLAN number.

Action No action is required. (This message pairs with the FM-3-NOLABELVL message and means that the previous error condition has rectified itself.)

 FM-3-INSERTFAIL: Insert of access-map [chars] [dec] into [chars] label [dec] 
failed.

Explanation    This message means that the system ran out of CPU DRAM when trying to merge sections of an access map. The first [chars] is the map name, and the second [chars] is the direction in which the map was applied. The first [dec] is the entry number, and the second [dec] is the label number.

Action Reduce other system activity to ease the memory demands. For example, remove any ACLs that have been defined but are not now used. Use simpler ACLs with fewer access control entries (ACEs). Use fewer VLANs, and remove any unneeded VLANs from the VLAN database. If the conditions warrant, upgrade to a larger memory configuration.

 FM-3-MERGEFAIL: [chars] ACL merge error [dec] on label [dec].

Explanation    This message means that the feature manager was unable to complete the merge of the configured features into a form suitable for loading into the hardware. Packets potentially affected by this feature are sent to the CPU for processing. The CPU processing needed to uphold the overflowed ACL severely degrades performance. [chars] is the ACL-type error (IP or MAC). The first [dec] is the error code, and the second [dec] is the label number.

Action Reorganize the ACLs so that all entries fit into hardware. Use less complicated and fewer ACLs.

 FM-3-NOLABEL: Cannot allocate [chars] label for interface [chars].

Explanation    This message means that the feature manager was unable to allocate a label for the features on this interface. This means that the hardware cannot be programmed to implement the features, and packets for this interface will be filtered in software. There is a limit of 256 labels per direction. The first [chars] is the direction (input or output); the second [chars] is the interface name.

Action Reorganize the ACLs so that all entries fit into hardware. Use less complicated and fewer ACLs.

 FM-3-NOLABELVL: Cannot allocate [chars] label for VLAN [dec].

Explanation    This message means that the feature manager was unable to allocate a label for the features on this VLAN. This means that the hardware cannot be programmed to implement the features, and packets on this VLAN will be filtered in software. There is a limit of 256 labels per direction. [chars] is the direction (input or output); [dec] is the VLAN number.

Action Allocate more space to the relevant section of the TCAM and reboot the switch, or use a simpler configuration. Use the same VLAN map on multiple VLANs, if possible.

 FM-3-NULLCPU: Sending traffic on empty [chars] label [dec] to CPU.

Explanation    This message means that an internal software error occurred. [chars] is the direction (input or output), and [dec] is the label number.

Action Copy the error message exactly as it appears on the console or in the system log, call your Cisco technical support representative, and provide the representative with the gathered information.

 FM-3-RELOADED: Reloading [chars] label [dec] feature.

Explanation    This message means that the feature manager was able to fit more of the configured features on this label into the hardware. One or more features were previously unloaded because of a lack of space. [chars] is the direction (input or output), and [dec] is the label number.

Action No action is required.

 FM-3-TOSCOST: Minimize monetary cost TOS bit unsupported in hardware, ignored.

Explanation    This hardware platform does not support filtering based on the type of service (TOS) and precedence; it supports filtering based on differentiated services code points (DSCPs). The DSCP field does not include the minimize monetary cost bit from the TOS field; hardware ignores this bit when checking for a match to an access control entry (ACE), which can lead to unintended filtering actions.

Action Design filters that do not test for the minimum monetary cost TOS.

 FM-3-UNLOADING: Unloading [chars] label [dec] feature.

Explanation    This message means that the feature manager was unable to fit the complete configuration into the hardware, so some features will be applied in software. This error prevents some or all of the packets in a VLAN from being forwarded in hardware and requires them to be forwarded by the CPU. Multicast packets might be dropped instead of being forwarded. [chars] is the direction (input or output), and [dec] is the label number.

Action Allocate more space to the relevant section of the TCAM by using the sdm prefer global configuration command and reboot the switch, or use a simpler configuration. Use the same access control lists on multiple interfaces, if possible.

 FM-7-TRANSDEF: No augmentation function found for VMR.

Explanation    This message means that an internal error occurred. An access control list was not correctly interpreted. The value-mask result (VMR) is incorrect.

Action Copy the error exactly as it appears on the console or in the system log, call your Cisco technical support representative, and provide the representative with the gathered information.

output side.

Explanation    This message means that the set or trust policy-map class configuration command configured for a policy map take affect only if the policy map is attached to input side of an interface. If you attempt to attach a policy map with the set or trust actions to the output side, a warning message is logged, and the actions do not take affect on output side. This is a hardware limitation.

Action Remove the set or trust command from the policy map attached to the output side.

Spanning-Tree Messages

This section contains the spanning-tree messages:

 SPANTREE-2-BLOCK-PVD-PEER: Blocking on [chars] [chars]. Inconsistent peer vlan.

Explanation    This message means that the spanning-tree port associated with the listed spanning-tree instance and interface will be held in spanning-tree blocking state until the port VLAN ID (PVID) inconsistency is resolved. The listed spanning-tree instance is that of the native VLAN ID of the interface on the peer switch to which the listed interface is connected. The first [chars] is the spanning-tree instance; the second [chars] is the interface.

Action Verify that the configuration of the native VLAN ID is consistent on the interfaces on each end of the 802.1Q trunk connection. Once corrected, spanning tree automatically unblocks the interfaces as appropriate.

 SPANTREE-2-BLOCK-PVID-LOCAL: Blocking [chars] on [chars] Inconsistent local vlan.

Explanation    This message means that the spanning-tree port associated with the listed spanning-tree instance and interface will be held in spanning-tree blocking state until the port VLAN ID (PVID) inconsistency is resolved. The listed spanning-tree instance is that of the native VLAN ID of the listed interface. The first [chars] is the spanning-tree instance; the second [chars] is the interface.

Action Verify that the configuration of the native VLAN ID is consistent on the interfaces on each end of the 802.1Q trunk connection. Once corrected, spanning tree automatically unblocks the interfaces as appropriate.

 SPANTREE-2-RECV-1Q-NON-1QTRUNK: Received 802.1Q BPDU on non 802.1Q trunk [chars] 
[chars].

Explanation    This message means that the listed interface, on which an SSTP BPDU was received, was in trunk mode but was not using 802.1Q encapsulation. [chars] are the connected interfaces.

Action Verify that the configuration and operational state of the listed interface and that of the interface to which it is connected are in the same mode (access or trunk). If the mode is trunk, verify that both interfaces have the same encapsulation (ISL or 802.1Q). Once these parameters are consistent, spanning tree automatically unblocks the interface as appropriate.

 SPANTREE-2-RECV-BAD-TLV: Received SSTP BPDU with bad TLV on [chars] [chars].

Explanation    This message means that the listed interface received an SSTP BPDU that was missing the VLAN ID tag. The BPDU is discarded. [chars] is the interface that received the SSTP BPDU.

Action If the message recurs, copy the message exactly as it appears on the console or in the system log, call your Cisco technical support representative, and provide the representative with the gathered information.

[chars] [chars].

Explanation    This message means that the listed interface received an SSTP BPDU that is tagged with a VLAN ID that does not match the VLAN ID on which the BPDU was received. This occurs when the native VLAN is not consistently configured on both ends of an 802.1Q trunk. [dec] is the VLAN ID; [chars] are the connected interfaces.

Action Verify that the configuration of the native VLAN ID is consistent on the interfaces on each end of the 802.1Q trunk connection. Once corrected, spanning tree automatically unblocks the interfaces as appropriate.

 SPANTREE-2-RX-PORTFAST: Received BPDU on PortFast enabled port. Disabling [chars].

Explanation    This message means that a BPDU was received on the listed interface, which has the spanning-tree PortFast feature enabled. Because spanning-tree BPDU guard is also enabled, the interface is administratively shut down. [chars] is the interface that received the BPDU.

Action Verify the PortFast configuration on the interface. If the PortFast behavior is desired, verify that the interface is connected to only a host or router and not to a bridge or a switch. After resolving the conflict, re-enable the interface by entering the no shutdown interface configuration command.

 SPANTREE-2-UNBLOCK-CONSIST-PORT: Unblocking [chars] on [chars]. Port consistency 
restored.

Explanation    This message means that the port VLAN ID or port type inconsistencies have been resolved and spanning tree will unblock the listed interface of the listed spanning-tree instance as appropriate. The first [chars] is the spanning-tree instance; the second [chars] is the interface.

Action No action is required.

 SPANTREE-3-PORT_SELF_LOOPED: [chars] disabled.- received BPDU src mac [enet] same 
as that of interface.

Explanation    This message means that a bridge protocol data unit (BPDU) was received on the listed interface with a source MAC address that matches the one assigned to the listed interface. This means that a port might be looped back to itself, possibly because of an installed diagnostic cable. The interface will be administratively shutdown. [chars] is the interface that received the BPDU; [enet] is the source MAC address.

Action Check the interface configuration and any cable plugged into the interface. Once the problem is resolved, re-enable the interface by entering the no shutdown interface configuration command.

 SPANTREE-7-BLOCK-PORT-TYPE: Blocking [chars] on [chars]. Inconsistent port type.

Explanation    This message means that the listed interface is being held in the spanning-tree blocking state until the port type inconsistency is resolved. The first [chars] is the spanning-tree instance; the second [chars] is the interface.

Action Verify that the configuration and operational state of the listed interface and that of the interface to which it is connected are in the same mode (access or trunk). If the mode is trunk, verify that both interfaces have the same encapsulation (ISL or 802.1Q). Once these parameters are consistent, spanning tree automatically unblocks the interface as appropriate.

 SPANTREE-7-RECV-1Q-NON-TRUNK: Received 802.1Q BPDU on non trunk [chars] [chars].

Explanation    This message means that a Shared Spanning Tree Protocol (SSTP) BPDU was received on the listed interface, which is not an operational trunking interface. [chars] are the connected interfaces.

Action Verify that the configuration and operational state of the listed interface and that of the interface to which it is connected are in the same mode (access or trunk). If the mode is trunk, verify that both interfaces have the same encapsulation (none, ISL, or 802.1Q). Once these parameters are consistent, spanning tree automatically unblocks the interface as appropriate.
