Messages and Recovery Procedures
This chapter lists and describes the Cisco IOS system error messages for the Catalyst 4500 series switch by facility. Within each facility, the messages are listed by severity levels 0 to 7. The highest severity level is 0, and the lowest severity level is 7. Each message is followed by an explanation and a recommended action, if available.
The system sends these error messages to the console (and, optionally, to a logging server on another system). Not all system error messages indicate problems with your system; some are purely informational, while others help diagnose problems with communication lines, internal hardware, or the system software.
Note
The messages listed in this chapter do not include the date/time stamp designation; the date/time stamp designation is displayed only if the software is configured for system log messaging.
Note
Note
When resolving system/hardware errors, you might need to contact your technical support representative for assistance. For detailed information on how to do this, see the Obtaining Technical Assistance section on page xvii.
ACL Messages
This section contains the access control list (ACL) message.
Error Message C4K_ACL-4-OUTOFMEMORY:Out of Memory while allocating [char]Explanation This message indicates that the software has failed to allocate memory for the given object while processing ACLs. Possibly, the configuration exceeded its maximum limit. If so, the feature using this ACL will not work.
Recommended Action If it is mandatory that the feature work normally, remove other unwanted features that require ACLs and retry the operation. If there are no features using ACLs that can be removed, contact your technical support representative.
BUFFERMANAGER Messages
This section contains the memory buffer management (BUFFERMANAGER) message.
Error Message C4K_BUFFERMANAGER-3-OUTOFVBUFS: Have run out of vbufs (internal buffers)Explanation This message indicates that the switch has run out of the internal memory buffers that are used for various tasks.
Explanation This is an unusual error because the internal buffers are generally used for only a short time, released, and then available for reuse. Usually this condition is transitory.
Recommended Action If the message reappears, reboot the system.
CHASSIS Messages
This section contains the chassis (CHASSIS) messages.
CHASSIS-2
Error Message C4K_CHASSIS-2-INSUFFICIENTFANSDETECTED:Too few working fans, the chassis will overheat. If not resolved, in 5 minutes all line cards will be placed into Reset-ModeExplanation This message indicates that one or more fans in the system fan tray or power supplies has failed. Although this is a minor alarm, system components could overheat and shut down.
Recommended Action Replace the system fan tray or broken fans.
Error Message C4K_CHASSIS-2-INSUFFICIENTFANSSHUTDOWN:Resetting linecards due to too few working fansExplanation This message indicates that one or more required fans in the fan tray or power supplies has failed. The modules have been reset to reduce heat generation.
Recommended Action Replace the broken fans as soon as possible.
Error Message C4K_CHASSIS-2-INSUFFICIENTPOWERDETECTED:
Insufficient power available for the current chassis configurationExplanation This message indicates that the current chassis configuration exceeds power availability. If this condition persists, the modules will reset.
Recommended Action If the power availability problem persists and impacts performance, replace the power supply with a larger capacity power supply.
Error Message C4K_CHASSIS-2-INSUFFICIENTPOWERSHUTDOWN:Resetting linecards due to insufficient powerExplanation This message indicates that the switch has been using more power than is available for the allowed time interval. The modules were reset to reduce power consumption.
Recommended Action If the power availability problem persists and impacts performance, replace the power supply with a larger capacity power supply.
Error Message C4K_CHASSIS-2-OVERHEATINGSHUTDOWN:Resetting linecards due to critical temperatureExplanation This message indicates that the maximum allowable operating temperature for the switch has been exceeded. The modules have been reset to reduce heat generation.

CHASSIS-3
Error Message C4K_CHASSIS-3-BADGBIC:Port [char]: Gbic's seeprom is bad, try reinserting: vendor: [char], p/n: [char], s/n: [char]Explanation This message indicates that a Gigabit Interface Converter (GBIC) with a serial EEPROM has been detected in the specified port in the message. Although a reading of the serial EEPROM's contents has succeeded, the contents are not valid (perhaps due to a bad checksum).
The message lists the vendor, part number, and serial number from the GBIC's serial EEPROM. This error might occur if the GBIC is not seated correctly.Recommended Action Remove and reinsert the GBIC. If this message appears repeatedly, insert the GBIC in another port to verify that it is the GBIC and not the port that is bad. If the GBIC fails in a different port, return the GBIC to your technical support representative for reprogramming. If the GBIC works in the other ports but not in the original port, the original port is bad, and you need to return the module to your representative for repair. To test the port further, insert a different GBIC into the port. If the other GBIC fails in that port, the port is bad.
Error Message C4K_CHASSIS-3-BADMACRANGEINSPROM:Module [dec]'s serial eeprom contains [dec] mac addresses, but needs [dec]Explanation This message indicates that the module's serial EEPROM contains a range of MAC addresses for this module. The range should contain the same number of MAC addresses as front-panel ports, because each MAC address corresponds to a front-panel port. The contents of the module's serial EEPROM is incorrect, and the range is smaller than the number of front-panel ports for the module.
Recommended Action Return the module to Cisco to reprogram the serial EEPROM, and contact your technical support representative.
Error Message C4K_CHASSIS-3-DAUGHTERCARDSEEPROMREADFAILED:Failed to read the serial eeprom on module [dec], daughter card [dec]Explanation This message indicates that the serial EEPROM for a daughter card on the specified module is unreadable. Because reading this EEPROM is the only way to determine the type of card, the card remains offline, as if it was not installed on the module.
Recommended Action Remove the module, and then remove and reseat the daughter card in the module. If this message reappears after you reinsert the module into the switch, the serial EEPROM might be bad. Return the module to Cisco, and contact your technical support representative.
Error Message C4K_CHASSIS-3-GBICSEEPROMREADFAILED:Failed to read gbic serial eeprom on port [char], try reinsertingExplanation This message indicates that a Gigabit Interface Converter (GBIC) with a serial EEPROM has been detected in the specified port, but a reading of the contents of the EEPROM has failed. The EEPROM must be read to determine the GBIC type. The read might fail if the GBIC is not seated correctly.
Recommended Action Remove and reinsert the GBIC. If this message reappears, insert the GBIC in another port to verify that it is the GBIC and not the port that is bad. If the GBIC fails in the other port, return the GBIC to your technical support representative for reprogramming. If the GBIC works in the other ports but not in the original port, the original port is bad, and you need to return the module to your technical support representative for repair. To test the port further, insert a different GBIC into the port. If the other GBIC also fails in that port, the port is bad.
Error Message C4K_CHASSIS-3-INSUFFICIENTPOWER:Insufficient power to bring up module in slot [dec]Explanation This message indicates that the module type has been identified, but the switch does not have sufficient power to bring the module up. The switch holds the module in reset mode to consume less power.

EBM-4
Error Message C4K_EBM-4-HOSTFLAPPING:Host [mac-addr] in vlan [dec] is flapping between port [char] and port [char]Explanation This message indicates that the specified host is detected as a source address on multiple ports. Normally, a host is supposed to be learned on only one port. The most common cause of this condition is spanning tree loops. All traffic from the specified host is temporarily dropped. After 15 seconds, forwarding is reenabled.
Recommended Action If the problem persists, the traffic from the problem host will continue to be dropped indefinitely.
Error Message C4K_EBM-4-ZEROETHERADDR:Filtering Ethernet MAC address of value zero from agent host table interface (port: [char])Explanation This message indicates that the switch has learned about a host with the MAC address 00:00:00:00:00:00. This MAC address is not valid and was probably generated by some non-IEEE 802.1D-compliant hardware or software in the network.
The host sort algorithm does not sort hosts with MAC addresses with all zeros (00:00:00:00:00:00), so a MAC address with all zeros is not listed in the learned host table. A request to show learned hosts, either by the show cam dynamic command or by an SNMP request, will not list a MAC address with all zeros.
Recommended Action Track the source of the bad MAC address, because it might cause other problems.

SPANTREE Messages
This section contains the Spanning Tree Protocol (SPANTREE) messages.
SPANTREE-2
Error Message SPANTREE-2-BLOCK_BPDUGUARD:Received BPDU on port [char] with BPDU Guard enabled. Disabling port.Explanation This message indicates that a BPDU was received in the specified interface that has the spanning tree BPDU guard feature enabled. As a result, the interface was administratively shut down.
Recommended Action Either remove the device sending BPDUs, or disable the BPDU guard feature. BPDU guard can be locally configured on the interface or globally configured on all ports that have PortFast enabled. After the conflict has been resolved, reenable the interface by entering the no shutdown command in interface configuration mode.
Error Message SPANTREE-2-BLOCK_PVID_LOCAL: Blocking [char] on [char]. Inconsistent local vlan.Explanation This message indicates that the spanning tree port that is associated with the listed spanning tree instance [char] and interface [char] 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.
Recommended Action Verify that the configuration of the native VLAN ID is consistent on the interfaces at each end of the 802.1Q trunk connection. When the configuration is consistent, spanning tree automatically unblocks the interfaces.
Error Message SPANTREE-2-BLOCK_PVID_PEER: Blocking [char] on [char]. Inconsistent peer vlan.Explanation This message indicates that the spanning tree port (with spanning-tree port ID [char]) that is associated with the listed instance and interface will be held in 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.
Recommended Action Verify that the configuration of the native VLAN ID is consistent on the interfaces on each end of the 802.1Q trunk connection. When corrected, spanning tree automatically unblocks the interfaces.
Error Message SPANTREE-2-CHNL_MISCFG:Detected loop due to etherchannel misconfiguration of [chars] [chars]Explanation This message indicates that a misconfigured channel group (with channel group ID [chars]) was detected. For example, the ports of one side of the EtherChannel either are not configured to be in the channel or failed to bundle, while ports on the other side of the EtherChannel were successfully bundled.
Recommended Action Locate the misconfigured local ports by entering the show interfaces status err-disabled command. Check the EtherChannel configuration on the remote device by entering the show etherchannel summary command on the remote device. After the configuration is corrected, enter the shutdown/no shutdown command on the associated port-channel interface.
Error Message SPANTREE-2-LOOPGUARD_BLOCK: Loop guard blocking port [char] on [char].Explanation This message indicates that the spanning tree message age timer has expired, because no BPDUs were received from the designated bridge. Because this condition could be caused by an unidirectional link failure, the interface is put into blocking state and marked as loop guard inconsistent in order to prevent possible loops from being created.
Recommended Action Use the show spanning-tree inconsistentports command to review the list of interfaces with loop guard inconsistencies. Determine why devices that are connected to the listed ports are not sending BPDUs. One reason could be that they do not run the Spanning Tree Protocol; in this case, you should disable loop guard in the inconsistent interfaces or start the spanning tree protocol on the other side of the links, depending on the context. Another reason could be a failure in the cable: If the link has a failure that makes it unidirectional (you can transmit but you cannot receive), you should replace the old cable with a new cable.
Error Message SPANTREE-2-LOOPGUARD_CONFIG_CHANGE: Loop guard [char] on port [char].Explanation This message indicates that the spanning tree loop guard configuration for the listed interface has been changed. If enabled, the interface will be put into blocking state and marked as loop guard inconsistent when the message age timer expires because no BPDUs were received from the designated bridge. This feature is mainly used to detect unidirectional links.
Recommended Action Verify that this is the desired configuration for the listed interface. Correct it if this is not the desired configuration; otherwise, no further action is required.
Error Message SPANTREE-2-LOOPGUARD_UNBLOCK: Loop guard unblocking port [char] on [char].Explanation This message indicates that the listed interface has received a BPDU, and if the inconsistency was due to an unidirectional link failure, the problem does not exist anymore. The loop guard inconsistency is cleared for the interface, which is taken out of the blocking state.
Recommended Action This is an informational message only. No action is required.
Error Message SPANTREE-2-PVSTSIM_FAIL: Superior PVST BPDU received on VLAN [dec] port [char]Explanation This message indicates that when a PVST+ switch is connected to an MST switch, the IST root (MSTOO) becomes the root for all PVST+ spanning trees. Looping can occur if any PVST+ spanning tree has a root with a better preference than IST. To prevent looping, the port, which is on the MST switch that receives the superior message from the PVST+ side, is blocked by root guard.
When STP is converging after a new switch, or switch port, is added to the topology, this condition might happen transiently. The port unblocks automatically in such cases.
Recommended Action If the port remains blocked, identify the root bridge as reported in the message, and configure a worse priority for the VLAN spanning tree. There could be better PVST roots than the message indicates, and the port will not recover until all such roots are cleared. If you are unsure whether the roots are cleared, disable and enable the port again.
Error Message SPANTREE-2-RECV_1Q_NON_1QTRUNK: Received 802.1Q BPDU on non 802.1Q trunk [char] [char].Explanation This message indicates that a Shared Spanning Tree Protocol (SSTP) bridge protocol data unit (BPDU) was received on the listed interface. The interface was in trunk mode but was not using 802.1Q encapsulation. The interface ID is [char].
Recommended Action Verify that the configuration and operational state of the listed interface and 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.
Error Message SPANTREE-2-RECV_BAD_TLV:Received SSTP BPDU with bad TLV on [char][char].Explanation This message indicates that the listed interface has received an SSTP BPDU that was missing the VLAN ID tag. The BPDU is discarded. [char] is the interface ID.
Recommended Action If the error message reappears, copy the message exactly as it appears on the console or in the system log, and contact your technical support representative.
Error Message SPANTREE-2-RECV_PVID_ERR: Received BPDU with inconsistent peer vlan id [dec] on [char] [char]Explanation This message indicates that the listed interface has 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 error occurs when the native VLAN is not consistently configured on both ends of an 802.1Q trunk. [dec] is the VLAN ID. The interface ID is [char].
Recommended 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 the configuration is consistent, spanning tree automatically unblocks the interfaces.
Error Message SPANTREE-2-ROOTGUARD_BLOCK: Root guard blocking port [char] on [char].Explanation This message indicates that a BPDU was received on the listed interface that advertised a spanning tree root bridge that was superior to the one already in use. The interface is put into a blocking state and marked as root guard inconsistent to prevent a suboptimal spanning tree topology from forming.
Recommended Action Enter the show spanning-tree inconsistentports command to review the list of interfaces with root guard inconsistencies. Determine why devices that are connected to the listed ports are sending BPDUs with a superior root bridge, and then take action to prevent further occurrences. Once the invalid BPDUs have been stopped, the interfaces automatically recover and resume normal operation. By looking at the configuration, ensure that it is appropriate to have root guard enabled on the interface.
Error Message SPANTREE-2-ROOTGUARD_CONFIG_CHANGE: Root guard [char] on port [char].Explanation This message indicates that the spanning tree root guard configuration for the listed interface has been changed. If root guard is enabled, any BPDU that is received on the interface that advertises a superior spanning tree root bridge to that already in use will cause the interface to be put into blocking state and marked as root guard inconsistent.
Recommended Action Verify that this is the correct configuration for the listed interface. If this is not the correct configuration, change the configuration to one that is appropriate for the interface.
Error Message SPANTREE-2-ROOTGUARD_UNBLOCK:Root guard unblocking port [char] on [char].Explanation This message indicates that the listed interface is no longer receiving BPDUs that are advertising a superior root bridge. The root guard inconsistency is cleared for the interface and then is taken out of the blocking state if appropriate.
Recommended Action This is an informational message only. No action is required.
Error Message SPANTREE-2-UNBLOCK_CONSIST_PORT: Unblocking [char] on [char]. Port consistency restored.Explanation This message indicates that the port VLAN ID and/or port type inconsistencies have been resolved. The Spanning Tree Protocol will unblock the listed interface of the spanning tree instance. The interface ID is [char].
Recommended Action This is an informational message only. No action is required.
SPANTREE-3
Error Message SPANTREE-3-BAD_PORTNUM_SIZE:Rejected an attempt to set the port number field size to [dec] bits (valid range is [dec] to [dec] bits).Explanation This message indicates that the spanning tree port identifier is a 16-bit field that is, by default, divided evenly between the port priority and the port number. Each subfield is 8 bits wide, allowing the port number field to represent port numbers between 1 and 255. On systems with more than 255 ports, the STP subsystem must increase the size of the port number portion of the port ID to support the greater number of ports. This happens at system initialization because the maximum number of ports on a particular platform will not change. This error occurs because of an error in the platform-specific code that caused it to request more (or fewer) bits than were possible.
Error Message SPANTREE-3-PORT_SELF_LOOPED: [char] disabled.- received BPDU src mac ([mac-addr]) same as that of interfaceExplanation This message indicates that a BPDU with a source MAC address that matches the address assigned to the listed interface was received. A port looped back on itself, possibly due to a diagnostic cable that was plugged into the interface. The interface is administratively shut down. [char] is the interface ID.
Recommended Action Check the interface configuration and any cable that is plugged into the interface. Once the problem is resolved, reenable the interface by entering the no shutdown command on the interface.
SPANTREE-5
Error Message SPANTREE-5-EXTENDED_SYSID:Extended SysId [char] for type [char]Explanation This message indicates that the extended system ID feature has been either enabled or disabled for the given type of spanning tree. If the feature was enabled, the spanning tree instance identifier is stored in the lower portion of the bridge ID priority field; this will cause the allowed values for the bridge priority to be limited to the range of 0 to 61,440, in increments of 4096. If the feature was disabled, the bridge ID priority field consists entirely of the configured priority, but some spanning tree features might not be available on a given platform (for example, 4096 VLAN support). On some platforms, this feature might be mandatory.
Recommended Action This is an informational message only. No action is required.
SPANTREE-6
Error Message SPANTREE-6-PORT_STATE: Port [char] instance [dec] moving from [char] to [char]Explanation This message indicates that the spanning tree port has changed to another state.
Recommended Action No action is required.
SPANTREE-7
Error Message SPANTREE-7-BLOCK_PORT_TYPE: Blocking [char] on [char]. Inconsistent port type.Explanation This message indicates that the listed interface is being held in spanning tree blocking state until the port type inconsistency is resolved. The port ID is [char].
Recommended 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 type (ISL or 802.1Q). When these parameters are consistent, spanning tree automatically unblocks the interface.
Error Message SPANTREE-7-RECV_1Q_NON_TRUNK: Received 802.1Q BPDU on non trunk [char] [char].Explanation This message indicates that an SSTP BPDU was received on the listed interface, which is not an operational trunking interface. The interface ID is [char].
Recommended 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 type (none, ISL, or 802.1Q). Once these parameters are consistent, spanning tree automatically unblocks the interface.
Error Message SPANTREE_FAST-7-PORT_FWD_UPLINK: [char] [char] moved to Forwarding (UplinkFast).Explanation This message indicates that the listed interface has been selected as the new root port for the listed spanning tree instance.
Recommended Action This is an informational message only. No action is required.
SPANTREE_VLAN_SW Messages
This section contains the spanning tree fast convergence (SPANTREE_VLAN_SW) message.
Error Message SPANTREE_VLAN_SW-2-MAX_INSTANCE:Platform limit of [dec] STP instances exceeded. No instance created for [char] (port [char]).Explanation This message indicates that the number of currently active VLAN spanning tree instances has reached a platform specific limit. No additional VLAN instances will be created until the number of instances drops below that limit.
Recommended Action Reduce the number of currently active spanning tree instances by either disabling some of the instances or deleting the VLANs that are associated with them. You need to manually enable those spanning trees that could not be created due to limited instances.
STORM_CONTROL Messages
This section contains the broadcast storm control (STORM_CONTROL) messages.
Error Message STORM_CONTROL-3-FILTERED: A [char] storm detected on [char]. A packet filter action has been applied on the interface.Explanation This message indicates that the amount of traffic that has been detected on the interface has exceeded the configured threshold values. The system filters excess traffic when a packet is received. Packet traffic is not being forwarded by the system.
Recommended Action Determine and fix the root cause of the excessive traffic on the interface.
Error Message STORM_CONTROL-3-SHUTDOWN: A packet storm was detected on [char]. The interface has been disabled.Explanation This message indicates that the amount of traffic that has been detected on the interface has exceeded the configured threshold values. Because the interface was configured to be shut down if a packet storm event is detected, it has been placed in an error disable state.
Recommended Action If automatic recovery is preferred, the error disable recovery mechanism can be used. Determine and fix the root cause of the excessive traffic on the interface.
STORE Messages
This section contains the storage (STORE) message.
Error Message C4K_STORE-2-OUTOFCHUNKS:Out of chunks of memoryExplanation This message indicates that the system has run out of memory.
