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 messages are purely informational, while other messages 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 Writing to a module's serial EEPROM is not standard practice; when the module comes from the factory, the serial EEPROM is set to the correct values. We do not recommend that you change the factory defaults, because this action can cause the module to malfunction.


If the explanation that is provided for a given command does not sufficiently explain your problem and no recommended action is given, copy the error message exactly as it appears on the console or in the system log.

You should research and attempt to resolve the error using the Output Interpreter at this URL: https://www.cisco.com/cgi-bin/Support/OutputInterpreter/home.pl.

You can also enter the show tech-support command to gather additional information about the error. If the error message text, information from the Output Interpreter, or output from the show tech-support command do not help you solve the problem, contact your technical support representative and provide the representative with the information that you have gathered. For detailed information on how to contact your techincal support  representative, see the Obtaining Technical Assistance section on page xii.

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. The configuration might have 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.

C4K_JOB Message

This section contains the job management(C4K_JOB) message.

Error Message    C4K_JOB-4-OVERRUN: Job <job-num> ran <number> microseconds (its 
runTimeMax was <number>).

Explanation    This message is printed for accounting purposes. It can be safely ignored.

Recommended Action    This message should only appear in debug mode. If you see this message without debugging turned on, please check the Bug Toolkit to search for bugs. If you do not find an existing bug, get the output of the show version and show running commands and contact your technical support representative.

C4K_MDIO Message

This section contains the memory access (C4K_MDIO) message.

Error Message    C4K_MDIO-3-READNON0ERROR: MDIO device <device-num>: first bit after TA 
wasn't 0.

Explanation    This message indicates an internal memory failure. If this message is seen occasionally, it can be ignored. If it is seen frequently, it indicates faulty hardware.

Recommended Action    If this message is only seen once or is seen infrequently, it can be ignored. If it appears frequently, replace the identified hardware.

Error Message    

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. This error is unusual because the internal buffers are used for only a short time, released, and then available for reuse. Typically, this condition is transitory.

Recommended Action    If the message reappears, reboot the switch.

CHASSIS Messages

This section contains the chassis (CHASSIS) messages.

CHASSIS-2

Error Message    C4K_CHASSIS-2-INLINEPOWEROFF:Inline power to the switch has been 
turned off

Explanation    This message indicates that the software has detected that the pass-through current is disabled. This condition will cause all phones drawing inline power from the switch to be powered off.

Recommended Action    If you want inline power, verify that the inline power switch on the switch is turned on.

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-Mode

Explanation    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. This message could be a false positive if there is indication that the fan-tray failed but then seems to recover automatically within few seconds. Refer to bug id CSCeg70330.

Recommended Action    Replace the system fan tray if you verify with LEDs or output from a show environment status command.

Error Message    C4K_CHASSIS-2-INSUFFICIENTFANSSHUTDOWN:Resetting linecards due to too 
few working fans

Explanation    This message indicates that one or more required fans in the fan tray or the 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 configuration

Explanation    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 power supply that has a larger capacity.

Error Message    C4K_CHASSIS-2-INSUFFICIENTPOWERSHUTDOWN:Holding module in slot [dec] 
in reset, due to insufficient power

Explanation    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 power supply that has a larger capacity.

Error Message    C4K_CHASSIS-2-OVERHEATINGSHUTDOWN:Resetting linecards due to critical 
temperature

Explanation    This message indicates that the maximum allowable operating temperature for the switch has been exceeded. The modules have been reset to reduce heat generation.

Recommended Action    Verify that the switch is in the proper operating environment and that the fans are functioning properly.

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 (possibly due to a bad checksum).

The message lists the vendor, part number, and serial number from the GBIC's serial EEPROM. This error occurs 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 technical support 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 reinserting

Explanation    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.

Recommended Action    Add or replace a power supply to expand the power capacity of the chassis.

Error Message    C4K_CHASSIS-3-INSUFFICIENTPOWERSUPPLIESDETECTED:
Insufficient power supplies present for specified configuration

Explanation    This message indicates that the system software has detected that the current chassis configuration has fewer power supplies than required for the existing configuration.

Recommended Action    Add a power supply to meet the needs of the current chassis configuration.

Error Message    C4K_CHASSIS-3-LINECARDNOTVALIDINSLOT: Module (Field Replaceable Unit 
minor type [dec]) is not supported in slot [dec]

Explanation    This message indicates that the line card type has been identified, but it cannot be supported in this slot due to the insufficient number of backplane ports in this slot.

Recommended Action    This is an informational message only. No action is required.

Error Message    C4K_CHASSIS-3-LINECARDSEEPROMREADFAILED:Failed to read module [dec]'s 
serial eeprom, try reinserting module

Explanation    This message indicates that the switch cannot read the serial EEPROM of the specified module, and the module will not boot because the EEPROM failed to identify the module type. The read might fail if the module is not seated correctly in the slot.

Recommended Action    Remove and reinsert the module. If this message reappears, reboot the switch. If the switch is still unable to read the EEPROM, return the module to Cisco, and contact your technical support representative.

Error Message    C4K_CHASSIS-3-LINECARDSEEPROMWRITEFAILED:Failed to write module 
[dec]'s serial eeprom

Explanation    This message indicates that writing to the serial EEPROM has failed. The write might fail if the module is not seated correctly in the slot.

Recommended Action    Remove and reinsert the module. If this message reappears, reboot the switch. If the switch is still unable to write to the EEPROM, return the module to Cisco, and contact your technical support representative.

Error Message    C4K_CHASSIS-3-MDIOREADERROR: MDIO read for device <device-num>, phy 
<phy-num> and register <reg-num> failed.

Explanation    This message indicates an internal memory failure. If this message is seen occasionally, it can be ignored. If it is seen frequently, it indicates faulty hardware.

Recommended Action    If this message is only seen once or is seen infrequently, it can be ignored. If it appears frequently, replace the identified hardware.

Error Message    C4K_CHASSIS-3-MIXINPOWERDETECTED:Power supplies in the chassis are of 
different types (AC/DC) or wattage

Explanation    This message indicates that the software has detected different kinds of power supplies in the chassis. In a Catalyst 4006 chassis, the power values default to the wattage of the weakest power supply. If you mix power supplies in a Catalyst 4500 series chassis, the switch will use the power supply in power supply bay 1 (PS1) and ignore the power supply in power supply bay 2 (PS2). We do not recommend mixing power supplies of different wattages.

Recommended Action    Verify that both power supplies are the same kind and wattage.

Error Message    C4K_CHASSIS-3-MODULENOTSUPPORTHALF:Module [dec] does not support 10 Mb 
or 100Mb Half duplex operation. Please have your card upgraded if you need half 
duplex operation.

Explanation    This message indicates that some preproduction boards have interfaces that do not work in half-duplex mode.

Recommended Action    Contact your technical support representative, and return the switch to Cisco for replacement.

Error Message    C4K_CHASSIS-3-ONLYLXSFPSALLOWED:Port [char] has a non-LX SFP, which is 
not supported

Explanation    This message indicates that the WS-X4448-GB-LX module supports only LX SFP. It marks any other type of Small Form-factor Pluggable (SFP) as faulty.

Recommended Action    Replace the SFP with an LX SFP that is known to be supported by Cisco.

Error Message    C4K_CHASSIS-3-OUTOFMEMORY:Ran out of memory - cannot allocate internal 
buffers

Explanation    This message indicates that the switch has run out of memory in the temporary buffers.

Recommended Action    If this message reappears, reboot the switch.

Error Message    C4K_CHASSIS-3-SEEPROMREADFAILEDAFTERWRITE:Error reading back module 
[dec]s serial EEPROM data after write

Explanation    This message indicates that after writing a module's serial EEPROM in response to a CLI request, the switch tries to read it back in, to ensure that the correct values were written out. What the switch reads back in differs from what the switch wrote out. The read or write might fail if the module is not seated correctly in the slot.

Recommended Action    Remove and reinsert the module. If that does not work, reboot the switch. If the read or write still fails, return the module to Cisco, and contact your technical support representative.


Note Writing the module's serial EEPROM is not standard practice; when the module comes from the factory, its serial EEPROM is set to the correct values. We do not recommend that you change the factory defaults, because this action could cause the module to malfunction.


Error Message    C4K_CHASSIS-3-SFPCRCINTEGRITYCHECKFAILED:SFP integrity check on port 
[char] failed: bad crc

Explanation    This message indicates that only the Cisco-qualified Small Form-factor Pluggables (SFPs) are supported. Other SFPs place the associated port in a faulty status.

The checksum of the SFP SEEPROM is not valid, indicating a bad or non-Cisco SFP.

Recommended Action    Replace the SFP with an SFP that is known to be supported by Cisco.

Error Message    C4K_CHASSIS-3-SFPINTEGRITYCHECKFAILED:SFP integrity check on port 
[char] failed: bad key

Explanation    This message indicates that only the Cisco-qualified Small Form-factor Pluggables (SFPs) are supported. Other SFPs place the associated port in a faulty status.

Recommended Action    Replace the SFP with an SFP that is known to be supported by Cisco.

Error Message    C4K_CHASSIS-3-SFPSERIALINTEGRITYCHECKFAILED:SFPs on ports [char] and 
[char] have duplicate serial numbers

Explanation    This message indicates that only the Cisco-qualified Small Form-factor Pluggables (SFPs) are supported. Other SFPs place the associated port in the faulty status.

All SFPs must have a unique serial number. This message indicates a cloned SFP SEEPROM.

Recommended Action    Replace the SFP with an SFP that is known to be supported by Cisco.

Error Message    C4K_CHASSIS-3-STUBPHYMISMATCH: Stub type mismatch: stub [dec]/[dec] is 
type [dec], should be type [dec]

Explanation    This message indicates that the stubs have nonmatching physical types for the specified module.

Recommended Action    Verify that the physical types for every stub on the module match.

Error Message    C4K_CHASSIS-3-TEMPERATURESENSORREADFAILED: Failed to read the 
supervisor temperature sensor

Explanation    The temperature sensor on the supervisor engine cannot be read. If the chassis becomes overheated, this condition will not be reported.

Recommended Action    If this message appears only once, this error could be transient and no action is required. If this message appears repeatedly (once every 30 minutes), inspect and, if necessary, replace the temperature sensor on the supervisor engine.

Error Message    C4K_CHASSIS-3-UNKNOWNLINECARD:Unknown module (Field Replaceable Unit 
minor type [dec]) in slot [dec]

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    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] is 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 is 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 are 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 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 occurs 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 a switch port is added to the topology, this condition occurs 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, contact your technical support representative, and provide the representative with the gathered information.

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 condition 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 enable root guard 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 the one that is 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 condition occurs 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.

Recommended Action    Contact your technical support representative.

Error Message    SPANTREE-3-PORT_SELF_LOOPED: [char] disabled.- received BPDU src mac 
([mac-addr])  same as that of interface

Explanation    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-4

Error Message    SPANTREE-4-PORT_NOT_FORWARDING: [char] [char] [char] [char] 

Explanation    This message indicates that the specified interface is not in the forwarding state and forwarding packets.

Recommended Action    Contact your technical support representative.

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).

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 cannot 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 errdisable state.

Recommended Action    If automatic recovery is preferred, the errdisable 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 memory
