Recommended Action None required.
105010
Error Message %FWSM-3-105010: (Primary) Failover message block alloc failedExplanation Block memory was depleted. This is a transient message and the module should recover. (Primary) can also be listed as (Secondary) for the secondary unit.
Recommended Action Use the show blocks command to monitor the current block memory.
105038
Error Message %FWSM-1-105038: (Primary) Interface count mismatchExplanation This failover message indicates that the number of interfaces configured on the primary and secondary units does not match. Failover cannot be enabled until both the primary and secondary units have the same number of interfaces. (Primary) can also be listed as (Secondary) for the secondary unit.
Recommended Action Check the VLAN configuration on the primary and secondary units. Look for any nameif command failure on the primary unit. After these configurations are verified and corrected, enter the failover comamnd on the primary unit to enable failover again.
105039
Error Message %FWSM-1-105039: (Primary) Unable to verify the Interface count with mate. Failover may be disabled in mate.Explanation Failover initially verifies that the number of interfaces configured on the primary and secondary modules are the same. This message indicates that the primary module is not able to verify the number of interfaces configured on the secondary module. This message indicates that the primary module is not able communicate with the secondary module over the failover interface. (Primary) can also be listed as (Secondary) for the secondary module.
Recommended Action Verify the failover VLAN, interface configuration, and status on the primary and secondary modules. Make sure the secondary module is running the firewall application and failover is enabled.
105040
Error Message %FWSM-1-105040: (Primary) Mate failover version is not compatible.Explanation The primary and secondary module should run the same failover software version to act as a failover pair. This message indicates that the secondary module's failover software version is not compatible with the primary module. Failover would be disabled on the primary module. (Primary) can also be listed as (Secondary) for the secondary module.
Recommended Action Maintain consistent software versions between the primary and secondary modules to enable failover.

Recommended Action None required.
105043
Error Message %FWSM-1-105043: (Primary) Failover interface failedExplanation Interface used to send failover messages to the secondary module failed. The active module remains as active and the standby module remains as standby. There will not be any failure detection or switchover activity until the failover interface becomes normal. (Primary) can also be listed as (Secondary) for the secondary module.
Recommended Action Verify that the VLAN is correctly configured and that the failover interface is configured as Secondary.
105044
Error Message %FWSM-1-105044: (Primary) Mate operational mode mode is not compatible with my mode mode.Explanation When the operational mode (single or multi) does not match between failover peers, failover will be disabled.
Recommended Action Configure the failover peers to have the same operational mode and then reenable failover.
105045
Error Message %FWSM-1-105045: (Primary) Mate license (number contexts) is not compatible with my license (number contexts).Explanation When the feature licenses do not match between failover peers, failover will be disabled.
Recommended Action Configure the failover peers to have the same feature license and then reenable failover.
106001
Error Message %FWSM-2-106001: Inbound TCP connection denied from IP_address/port to IP_address/port flags tcp_flags on interface interface_nameExplanation This is a connection-related message. This message occurs when an attempt to connect to an inside address is denied by your security policy. Possible tcp_flags values correspond to the flags in the TCP header that were present when the connection was denied. For example, a TCP packet arrived for which no connection state exists in the FWSM, and it was dropped. The tcp_flags values in this packet are FIN and ACK.
The tcp_flags values are as follows:–
–
–
–
–
–
Recommended Action None required.
106002
Error Message %FWSM-2-106002: protocol Connection denied by outbound list acl_ID src inside_address dest outside_addressExplanation This is a connection-related message. This message is logged if the specified connection fails because of an outbound deny command. The protocol variable can be ICMP, TCP, or UDP.
Recommended Action Use the show outbound command to check outbound lists.
106006
Error Message %FWSM-2-106006: Deny inbound UDP from outside_address/outside_port to inside_address/inside_port on interface interface_name.Explanation This is a connection-related message. This message is logged if an inbound UDP packet is denied by your security policy.
Recommended Action None required.
106007
Error Message %FWSM-2-106007: Deny inbound UDP from outside_address/outside_port to inside_address/inside_port due to DNS {Response|Query}.Explanation This is a connection-related message. This message is logged if a UDP packet containing a DNS query or response is denied.
Recommended Action If the inside port number is 53, the inside host probably is set up as a caching name server. Add an access-list command statement to permit traffic on UDP port 53. If the outside port number is 53, a DNS server was probably too slow to respond, and the query was answered by another server.
106010
Error Message %FWSM-3-106010: Deny inbound protocol src interface_name:dest_address/dest_port dst interface_name:source_address/source_portExplanation This is a connection-related message. This message is logged if an inbound connection is denied by your security policy.
Recommended Action Modify the security policy if traffic should be permitted. If the message occurs at regular intervals, contact the remote peer administrator.
106011
Error Message %FWSM-3-106011: Deny inbound (No xlate) stringExplanation The message will appear under normal traffic conditions if there are internal users that are accessing the Internet through a web browser. Any time a connection is reset, when the host at the end of the connection sends a packet after the module receives the reset, this message will appear. It can typically be ignored.
Recommended Action Prevent this syslog message from getting logged to the syslog server by entering the no logging message 106011 command.
106012
Error Message %FWSM-6-106012: Deny IP from IP_address to IP_address, IP options hex.Explanation This is a packet integrity check message. An IP packet was seen with IP options. Because IP options are considered a security risk, the packet was discarded.
Recommended Action Contact the remote host system administrator to determine the problem. Check the local site for loose source routing or strict source routing.
106013
Error Message %FWSM-2-106013: Dropping echo request from IP_address to PAT address IP_addressExplanation This message is logged when the module discards an inbound ICMP Echo Request packet with a destination address that corresponds to a PAT global address. The inbound packet is discarded because it cannot specify which PAT host should receive the packet.
Recommended Action None required.
106014
Error Message %FWSM-3-106014: Deny inbound icmp src interface_name: IP_address dst interface_name: IP_address (type dec, code dec)Explanation This message is logged when the module denies any inbound ICMP packet access. By default, all ICMP packets are denied access unless specifically permitted.
Recommended Action None required.
106015
Error Message %FWSM-6-106015: Deny TCP (no connection) from IP_address/port to IP_address/port flags tcp_flags on interface interface_name.Explanation This message is logged when the module discards a TCP packet that has no associated connection in the module's connection table. The module looks for a SYN flag in the packet, which indicates a request to establish a new connection. If the SYN flag is not set, and there is not an existing connection, the module discards the packet.
Recommended Action None required unless the module receives a large volume of these invalid TCP packets. If this is the case, trace the packets to the source and determine the reason these packets were sent.
106016
Error Message %FWSM-2-106016: Deny IP spoof from (IP_address) to IP_address on interface interface_name.Explanation This message is logged when the module discards a packet with an invalid source address. Invalid source addresses are those addresses belonging to the following:
–
–
–
If the sysopt connection enforcesubnet command is enabled, the FWSM discards packets that have a source address belonging to the destination subnet and prevents them from traversing the module.
Recommended Action Determine if an external user is trying to compromise the protected network. Check for misconfigured clients.
106017
Error Message %FWSM-2-106017: Deny IP due to Land Attack from IP_address to IP_addressExplanation This message appears when the module receives a packet with the IP source address equal to the IP destination, and the destination port equal to the source port. This message indicates a spoofed packet that is designed to attack systems. This attack is referred to as a Land Attack.
Recommended Action If this message persists, an attack may be in progress. The packet does not provide enough information to determine where the attack originates.
106018
Error Message %FWSM-2-106018: ICMP packet type ICMP_type denied by outbound list acl_ID src inside_address dest outside_addressExplanation This message is logged because the outgoing ICMP packet with the specified ICMP from local host (inside_address) to the foreign host (outside_address) is denied by the outbound ACL list.
Recommended Action None required.
106020
Error Message %FWSM-2-106020: Deny IP teardrop fragment (size = number, offset = number) from IP_address to IP_addressExplanation The module discarded an IP packet with a teardrop signature containing either a small offset or fragment overlapping. This is a hostile event that circumvents the firewall or an Intrusion Detection System.
Recommended Action Contact the remote peer administrator or escalate this issue according to your security policy.
106021
Error Message %FWSM-1-106021: Deny protocol reverse path check from source_address to dest_address on interface interface_nameExplanation Someone is attempting to spoof an IP address on an inbound connection. This message appears when you have enabled Unicast Reverse Path Forwarding (Unicast RPF) with the ip verify reverse-path command. Unicast RPF, also known as reverse route lookup, detected a packet that does not have a source address represented by a route and assumes that it is part of an attack on your firewall.
Recommended Action None required.
106022
Error Message %FWSM-1-106022: Deny protocol connection spoof from source_address to dest_address on interface interface_nameExplanation This message only appears if a connection exists and a packet matching the connection arrives on a different interface from the interface that the connection began on.
For example, if a user starts a connection on the inside interface, but the module detects the same connection arriving on a perimeter interface, the module has more than one path to a destination. This is known as asymmetric routing and is not supported on the module.
An attacker also might be attempting to append packets from one connection to another as a way to break into the firewall. In either case, the module displays this message and drops the connection.
Recommended Action This message appears when the ip verify reverse-path command is not configured. Check that the routing is not asymmetric.
106023
Error Message %FWSM-4-106023: Deny protocol src [interface_name:source_address/source_port] dst interface_name:dest_address/dest_port [type {string}, code {code}] by access_group acl_IDExplanation An IP packet was denied by the ACL. This message displays even if you do not have the log option enabled for an ACL.
Recommended Action If messages persist from the same source address, messages might indicate a foot-printing or port-scanning attempt. Contact the remote host administrators.
106024
Error Message %FWSM-2-106024: Access rules memory exhaustedExplanation This message reports that the access list compilation process has run out of memory. All configuration information that has been added since the last successful access list is removed from the system and the most recently compiled set of access lists will continue to be used.
Recommended Action Access lists, AAA, ICMP, SSH, Telnet, and other rule types are stored and compiled as access list rule types. Remove some of these rule types so that others can be added.
106025, 106026
Error Message %FWSM-6-106025: Failed to determine the security context for the packet:sourceVlan:sourceIP destIP sourcePort destPort protocolError Message %FWSM-6-106026: Failed to determine the security context for the packet:sourceVlan:sourceIP destIP sourcePort destPort protocolExplanation These messages are generated when the security context of the packet in multiple context mode cannot be determined. Both messages can be generated for IP packets being dropped in either router and transparent mode.
Recommended Action None required.
106027
Error Message %FWSM-4-106027:Failed to determine the security context for the packet:vlansource Vlan#:ethertype src sourceMAC dst destMACExplanation This message is generated when a packet is denied because of an EtherType ACL.
Recommended Action None required.
106100
Error Message %FWSM-6-106100: access-list acl_ID {permitted | denied | est-allowed} protocol interface_name/source_address(source_port) -> interface_name/dest_address(dest_port) hit-cnt number ({first hit | number-second interval})Explanation This message is logged when packets match an ACL statement, if you configured the log option for the access-list command. The message level depends on the level set in the access-list command (by default, the level is 6). The message indicates either the initial occurrance or the total number of occurrances during an interval. This message provides more information than message 106023, which only logs denied packets, and does not include the hit count or a configurable level. The following list describes the message values:
•
•
•
•
•
•
•
•
•
•
Recommended Action None required.
106101
Error Message %FWSM-1-106101: The number of ACL log deny-flows has reached limit (number).Explanation If you configured the log option for an ACL deny statement (access-list id deny command), and a traffic flow matches the ACL statement, the module caches the flow information. When the number of matching flows that are cached on the module exceeds the user-configured limit (access-list deny-flow-max command), this message is logged.
The number value is the limit configured using the access-list deny-flow-max command.
Recommended Action None required. This message might be generated as a result of a DoS attack.
107001
Error Message %FWSM-1-107001: RIP auth failed from IP_address: version=number, type=string, mode=string, sequence=number on interface interface_nameExplanation This is an alert log message. The module received a RIP reply message with bad authentication. This message might be caused by a misconfiguration on the router or the module or by an unsuccessful attempt to attack the routing table of the module.
Recommended Action This message indicates a possible attack and should be monitored. If you are not familiar with the source IP address listed in this message, change your RIP authentication keys between trusted entities. An attacker might be trying to determine the existing keys.
107002
Error Message %FWSM-1-107002: RIP pkt failed from IP_address: version=number on interface interface_nameExplanation This is an alert log message. This message could be caused by a router bug, a packet with non-RFC values inside, or a malformed entry. This should not happen, and may be an attempt to exploit routing table of the module.
Recommended Action This message indicates a possible attack and should be monitored. The packet has passed authentication, if enabled, and bad data is in the packet. Monitor the situation and change the keys if there are any doubts about the originator of the packet.
108002
Error Message %FWSM-2-108002: SMTP replaced string: out source_address in inside_address data: stringExplanation This is a Mail Guard (SMTP) message generated by the fixup protocol smtp command. This message is logged if the module replaces an invalid character in an e-mail address with a space.
Recommended Action None required.
109001
Error Message %FWSM-6-109001: Auth start for user user from inside_address/inside_port to outside_address/outside_portExplanation This is an authentication, authorization and accounting (AAA) message. This message is logged if the module is configured for AAA and detects an authentication request by the specified user.

Recommended Action None required.
109010
Error Message %FWSM-3-109010: Auth from inside_address/inside_port to outside_address/outside_port failed (too many pending auths) on interface interface_name.Explanation This is an AAA message. This message is logged if an authentication request cannot be processed because the server has too many requests pending.
Recommended Action Check to see if the authentication server is too slow to respond to authentication requests. Enable the Flood Defender feature with the floodguard enable command.
109011
Error Message %FWSM-2-109011: Authen Session Start: user 'user', sid numberExplanation An authentication session started between the host and the module and has not yet completed.
Recommended Action None required.
109012
Error Message %FWSM-5-109012: Authen Session End: user 'user', sid number, elapsed number secondsExplanation The authentication cache has timed out. Users must reauthenticate on their next connection. You can change the duration of this timer with the timeout uauth command.
Recommended Action None required.

The entire text of the element is included in the syslog message. This message is usually caused by an invalid access-list command statement.
Recommended Action Correct the ACL component that has the indicated error on the AAA server.
109022
Error Message %FWSM-4-109022: exceeded HTTPS proxy process limitExplanation For each HTTPS authentication, the module dedicates a process to service the authentication request. When the number of concurrently running processes exceeds the system-imposed limit, the module does not perform the authentication, and this message is displayed.
Recommended Action None required.
109023
Error Message %FWSM-3-109023: User from src_IP_Adress/src_port to dest_IP_Address/dest_port on interface outside must authenticate before using this service.Explanation This is a AAA message. Based on the configured policies, you need to be authenticated before you can use this service (port).
Recommended Action Have the user authenticate using Telnet, FTP or HTTP before attempting to use the above service (port).
109024
Error Message %FWSM-6-109024: Authorization denied from source_IP_Address/src_port to dest_IP_Address/dest_port (not authenticated) on interface interface_name using protocolExplanation This is an AAA message. This message is logged if the module is configured for AAA and a user attempted to make a TCP connection across the module without prior authentication.
Recommended Action None required.
109025
Error Message %FWSM-6-109025: Authorization denied (acl=acl_ID) for user user from source_address/source_port to dest_address/dest_port on interface interface_name using protocolExplanation The access control list check failed. The check either matched a deny or did not match anything, such as an implicit deny. The connection was denied by the user access control list acl_ID, which was defined per the AAA authorization policy on Cisco Secure Access Control Server (ACS).
Error Message None required.110001
Error Message %FWSM-6-110001: No route to dest_address from source_addressExplanation This message indicates a route lookup failure. A packet is looking for a destination IP address that is not in the routing table.
Recommended Action Check the routing table and make sure that there is a route to the destination.
111001
Error Message %FWSM-5-111001: Begin configuration: IP_address writing to deviceExplanation This message is logged when you enter the write command to store your configuration on a device (floppy disk, Flash memory, TFTP, the failover standby unit, or the console terminal).

Messages 201002 to 215001
This section contains messages from 201002 to 215001.
201002
Error Message %FWSM-3-201002: Too many TCP connections on {static|xlate} global_address! econns nconnsExplanation This is a connection-related message. This message is logged when the maximum number of TCP connections to the specified global address was exceeded. The econns variable is the maximum number of embryonic connections and the nconns variable is the maximum number of connections permitted for the static or xlate.
Recommended Action Use the show static or show nat command to check the limit imposed on connections to a static address. The limit is configurable.
201003
Error Message %FWSM-2-201003: Embryonic limit exceeded nconns/elimit for outside_address/outside_port (global_address) inside_address/inside_port on interface interface_nameExplanation This is a connection-related message regarding traffic to the module. This message is logged when the number of embryonic connections from the specified foreign address with the specified static global address to the specified local address exceeds the embryonic limit. When the limit on embryonic connections to the module is reached, the module attempts to accept them anyway, but puts a time limit on the connections. This situation allows some connections to succeed even if the module is very busy. The nconns variable lists the number of embryonic connections received and the elimit variable lists the maximum number of embryonic connections specified in the static or nat command.
Recommended Action This message indicates a more serious overload than message 201002. It could be caused by a SYN attack, or by a very heavy load of legitimate traffic. Use the show static command to check the limit imposed on embryonic connections to a static address.
201004
Error Message %FWSM-3-201004: Too many UDP connections on {static|xlate} global_address! udp conn limitExplanation This is a connection-related message. This message is logged when the maximum number of UDP connections to the specified global address was exceeded. The udp conn limit variable is the maximum number of UDP connections permitted for the static or translation.
Recommended Action Use the show static or show nat command to check the limit imposed on connections to a static address. You can configure the limit.
201005
Error Message %FWSM-3-201005: FTP data connection failed for IP_addrExplanation This message indicates that the module cannot allocate a structure to track the data connection for FTP because of insufficient memory.
Recommended Action Reduce the amount of memory usage or purchase additional memory.
201006
Error Message %FWSM-3-201006: RCMD backconnection failed for IP_address/portExplanation This is a connection-related message. This message is logged if the module is unable to preallocate connections for inbound standard output for rsh commands due to insufficient memory.
Recommended Action Check the rsh client version; the module only supports the Berkeley rsh. You can also reduce the amount of memory usage, or purchase additional memory.
202001
Error Message %FWSM-3-202001: Out of address translation slots!Explanation This is a connection-related message. This message is logged if the module has no more address translation slots available.
Recommended Action Check the size of the global pool compared to the number of inside network clients. A PAT address may be necessary. Alternatively, shorten the timeout interval of translates and connections. This error message could also be caused by insufficient memory; reduce the amount of memory usage if possible.
202005
Error Message %FWSM-3-202005: Non-embryonic in embryonic list outside_address/outside_port inside_address/inside_portExplanation This is a connection-related message. This message is logged when a connection object (xlate) is in the wrong list.
Recommended Action Contact Cisco TAC.
208005
Error Message %FWSM-3-208005: (function:line_num) FWSM clear command return codeExplanation The module received a nonzero value (an internal error) when attempting to clear the configuration in Flash memory. The message includes the reporting subroutine's filename and line number.
Recommended Action For performance reasons, the end host should be configured to not inject IP fragments. This configuration change is most likely due to NFS. Set the read and write size equal to the interface MTU for NFS.
209003
Error Message %FWSM-4-209003: Fragment database limit of number exceeded: src = IP_address,dest = IP_address, proto = protocol, id = numberExplanation Too many IP fragments are currently awaiting reassembly. By default, the maximum number of fragments is 200 (refer to the fragment size command in the Catalyst 6500 Series Switch and Cisco 7600 Series Router Firewall Services Module Command Reference to raise the maximum). The module limits the number of IP fragments that can be concurrently reassembled. This restriction prevents memory depletion at the module under abnormal network conditions. In general, fragmented traffic should be a small percentage of the total traffic mix. An exception is in a network environment with NFS over UDP where a large precentage is fragmented traffic; if this type of traffic is relayed through the module, consider using NFS over TCP instead. To prevent fragmentation, see the sysopt connection tcpmss bytes command in the Catalyst 6500 Series Switch and Cisco 7600 Series Router Firewall Services Module Command Reference.
Recommended Action If this message persists, a denial of service (DoS) attack might be in progress. Contact the remote peer's administrator or upstream provider.
209004
Error Message %FWSM-4-209004: Invalid IP fragment, size = bytes exceeds maximum size = bytes: src = IP_address, dest = IP_address, proto = protocol, id = numberExplanation An IP fragment is malformed. The total size of the reassembled IP packet exceeds the maximum possible size of 65,535 bytes.
Recommended Action A possible intrusion event may be in progress. If this message persists, contact the remote peer's administrator or upstream provider.
209005
Error Message FWSM-4-209005: Discard IP fragment set with more than number elements: src = Too many elements are in a fragment set.Explanation The module disallows any IP packet that is fragmented into more than 24 fragments.
Recommended Action A possible intrusion event may be in progress. If the message persists, contact the remote peer's administrator or upstream provider. You can change the number of fragments per packet by using the fragment chain xxx int_name command.
210002
Error Message %FWSM-3-210002: LU allocate block (bytes) failed.Explanation Stateful Failover could not allocate a block of memory to transmit stateful information to the standby module.
Recommended Action Check the failover interface using the show interface command to make sure its transmit is normal. Also check the current block memory using the show block command. If current available count is 0 within any of the blocks of memory, then reload the FWSM software to recover the lost blocks of memory.
210005
Error Message %FWSM-3-210005: LU allocate connection failedExplanation Stateful Failover cannot allocate a new connection on the standby unit. This may be caused by little or no RAM memory available within the module.
Recommended Action Check the available memory using the show memory command to make sure the module has free memory in the system. If there is no available memory, add more physical memory to the module.
210006
Error Message %FWSM-3-210006: LU look NAT for IP_address failedExplanation Stateful Failover was unable to locate a NAT group for the IP address on the standby unit. The active and standby firewall units may be out of synchronization.
Recommended Action Use the write standby command on the active unit to synchronize system memory with the standby unit.

Error Message %FWSM-3-210007: LU allocate xlate failedExplanation Stateful Failover failed to allocate a translation (xlate) slot record.
Recommended Action Clear the xlate memory.
210008
Error Message %FWSM-3-210008: LU no xlate for inside_address/inside_port outside_address/outside_portExplanation Unable to find a translation slot (xlate) record for a Stateful Failover connection; unable to process the connection information.
Recommended Action Enter the write standby command on the active unit to synchronize system memory between the active and standby units.
210022
Error Message %FWSM-6-210022: LU missed number updatesExplanation Stateful Failover assigns a sequence number for each record sent to the standby unit. When a received record sequence number is out of sequence with the last updated record, the information in between is assumed lost and this error message is sent.
Recommended Action Unless there are LAN interruptions, check the available memory on both FWSM units to ensure that there is enough memory to process the stateful information. Use the show failover command to monitor the quality of stateful information updates.
211001
Error Message %FWSM-3-211001: Memory allocation ErrorExplanation Failed to allocate RAM system memory.

Recommended Action This message indicates a configuration error. If dynamic NAT is desired for the source host, ensure that the nat command matches the source IP address. If static NAT is desired for the source host, ensure that the local IP address of the static command matches. If no NAT is desired for the source host, check the ACL bound to the NAT 0 ACL.
305006
Error Message %FWSM-3-305006: {outbound static|identity|portmap|regular) translation creation failed for protocol src interface_name:source_address/source_port dst interface_name:dest_address/dest_portExplanation A protocol (UDP, TCP, or ICMP) failed to create a translation through the firewall. The firewall provides this checking for addresses that are explicitly identified with static command statements. With the change, for inbound traffic, the firewall denies translations for a destined IP address identified as a network or broadcast address.
The firewall does not apply PAT to all ICMP message types; it only applies PAT ICMP echo and echo-reply packets (types 8 and 0). Specifically, only ICMP echo or echo-reply packets create a PAT xlate. So, when the other ICMP messages types are dropped, this message is generated.
The firewall utilizes the global IP and mask from configured static command statements to differ regular IP addresses from network or broadcast IP addresses. If the global IP address is a valid network address with a matching network mask, then the firewall does not create a translation for network or broadcast IP addresses with inbound packets.
For example:
static (inside,outside) 10.2.2.128 10.1.1.128 netmask 255.255.255.128
Global address 10.2.2.128 is responded to as a network address and 10.2.2.255 is responded to as the broadcast address. Without an existing translation, the firewall denies inbound packets destined for 10.2.2.128 or 10.2.2.255, and generates this system log message.
When the suspected IP is a host IP, configure a separated static command statement with a host mask in front of the subnet static (first match rule for static command statements). The following static causes the firewall to respond to 10.2.2.128 as a host address:
static (inside,outside) 10.2.2.128 10.2.2.128 netmask 255.255.255.255
static (inside,outside) 10.2.2.128 10.2.2.128 netmask 255.255.255.128The translation may be created by traffic started with the inside host with the questioned IP address. Because the firewall views a network or broadcast IP address as a host IP address with overlapped subnet static configuration, the network address translation for both static command statements must be the same.
Recommended Action None required.
305007
Error Message %FWSM-6-305007: addrpool_free(): Orphan IP IP_address on interface interface_numberExplanation The module has attempted to translate an address that it cannot find in any of its global pools. The module assumes that the address was deleted and drops the request.
Recommended Action None required.
305008
Error Message %FWSM-3-305008: Free unallocated global IP address.Explanation The module kernel detected an inconsistency condition when trying to free an unallocated global IP address back to the address pool. This abnormal condition may occur if the module is running a Stateful Failover setup and some of the internal states are momentarily out of synchronization between the active unit and the standby unit. This condition is not catastrophic, and the module recovers automatically.
Recommended Action Report this condition to Cisco TAC if you continue to see this message.
305009
Error Message %FWSM-6-305009: Built {dynamic|static} translation from interface_name:real_address to interface_name:mapped_addressExplanation An address translation slot was created.

Error Message %FWSM-3-322001: Deny MAC address mac-address, possible spoof attempt on interface interfaceExplanation The FWSM received a packet from the offending MAC address on the specified interface but the source MAC address in the packet is statically bound to another interface in your configuration. This could be caused by either be a MAC-spoofing attack or a misconfiguration.
Recommended Action Check the configuration and take appropriate action by either finding the offending host or correcting the configuration.
322002
Error Message %FWSM-3-322002: ARP inspection check failed for arp {request|response} received from host mac-address on interface interface. This host is advertising MAC Address mac-address-1 for IP Address ip-address, which is {statically|dynamically} bound to MAC Address mac-address-2.Explanation If the ARP inspection module is enabled, it checks whether a new ARP entry advertised in the packet conforms to the statically configured or dynamically learned IP-MAC address binding before forwarding ARP packets across the FWSM. If this check fails, the ARP inspection module drops the ARP packet and generates this message. This situation may be caused by either ARP spoofing attacks in the network or an invalid configuration (IP-MAC binding).
Recommended Action If the cause is an attack, you can deny the host using the ACLs. If the cause is an invalid configuration, correct the binding.

Recommended Action None required. This message is displayed to allow an institution to keep a record of shunning activity.
401003
Error Message %FWSM-4-401003: Shun deleted: IP_addressExplanation A single shunned host was removed from the shun database.
Recommended Action None required. This message is displayed to allow an institution to keep a record of shunning activity.
401004
Error Message %FWSM-4-401004: Shunned packet: IP_address ==> IP_address on interface interface_nameExplanation A packet was dropped because the host defined by IP SRC is a host in the shun database. A shunned host cannot pass traffic on the interface on which it is shunned. For example, an external host on the Internet can be shunned on the outside interface.
Recommended Action None required. This message provides a record of the activity of shunned hosts. This message and message %FWSM-4-401005 can be used to evaluate further risk assessment concerning this host.
401005
Error Message %FWSM-4-401005: Shun add failed: unable to allocate resources for IP_address IP_address port portExplanation The module is out of memory; a shun could not be applied.
Recommended Action The Cisco Intrusion Detection System should continue to attempt to apply this rule. Attempt to reclaim memory and reapply a shun manually, or wait for the Cisco Intrusion Detection System to do this.
402101
Error Message %FWSM-4-402101: decaps: rec'd IPSEC packet has invalid spi for destaddr=dest_address, prot=protocol, spi=numberExplanation Received IPSec packet specifies a security parameters index (SPI) that does not exist in the security association database (SADB). This may be a temporary condition due to slight differences in aging of SAs between the IPSec peers or it may be due to the clearing of the local SAs. This condition may also be caused by incorrect packets sent by the IPSec peer. This may also be an attack.
Recommended Action The peer may not acknowledge that the local SAs have been cleared. If a new connection is established from the local router, the two peers may then reestablish successfully. If the problem occurs for more than a brief period, either attempt to establish a new connection or contact the peer's administrator.
402102
Error Message %FWSM-4-402102: decapsulate: packet missing {AH|ESP}, destadr=dest_address, actual prot=protocolExplanation Received IPSec packet is missing an expected AH or ESP header. The peer is sending packets that do not match the negotiated security policy. This may be an attack.

The peer is sending other traffic through this security association because of a security association selection error by the peer. This may be a hostile event.
Recommended Action Contact the peer's administrator to compare policy settings.
402106
Error Message %FWSM-4-402106: Rec'd packet not an IPSEC packet (ip) dest_address= dest_address, src_addr= source_address, prot= protocolExplanation The received packet matched the crypto map ACL, but it is not IPSec-encapsulated; the IPSec peer is sending unencapsulated packets. This error can occur because of a policy setup error on the peer. For example, the module only accepts encrypted Telnet traffic to the outside interface port 23. If you attempt to Telnet without IPSec encryption to the outside interface on port 23, this message appears. This error can also signify a hostile event. This syslog message is not generated except under the conditions cited (for example, it is not generated for traffic to the module interfaces themselves). See messages 710001, 710002, and 710003 for messages that track TCP and UDP requests.
Recommended Action Contact the peer's administrator to compare policy settings.

You can check the size of the global pool compared to the number of inside network clients. A PAT address may be necessary. Alternatively, shorten the timeout interval of translates and connections. This error message may also be caused by insufficient memory; try reducing the amount of memory usage, or purchasing additional memory.
405102
Error Message %FWSM-4-405102: Unable to Pre-allocate H245 Connection for foreign_address outside_address[/outside_port] to local_address inside_address[/inside_port]Explanation The module failed to allocate RAM system memory while starting a connection or has no more address translation slots available.
Recommended Action If this message occurs periodically, it can be ignored. If it repeats frequently, contact Cisco TAC. You can also check the size of the global pool compared to the number of inside network clients. A PAT address may be necessary. Alternatively, shorten the timeout interval of translates and connections. This error message may also be caused by insufficient memory; try reducing the amount of memory usage, or purchasing additional memory.
405104
Error Message %FWSM-4-405104: H225 message received from outside_address/outside_port to inside_address/inside_port before SETUPExplanation This message appears after an H.225 message is received out of order. The H.225 message was received before the initial SETUP message, which is not allowed. The FWSM must receive an initial SETUP message for that H.225 call signalling channel before accepting any other H.225 messages.
Recommended Action None required.
406001
Error Message %FWSM-4-406001: FTP port command low port: IP_address/port to IP_address on interface interface_nameExplanation A client entered an FTP port command and supplied a port less than 1024 (in the well known port range typically devoted to server ports).

Recommended Action None required.
406002
Error Message %FWSM-4-406002: FTP port command different address: IP_address(IP_address) to IP_address on interface interface_nameExplanation A client issued an FTP port command and supplied an address other than the address used in the connection. This message indicates an attempt to avert the site's security policy. The module drops the packet, terminates the connection, and logs the event.
Recommended Action None required.
407002
Error Message %FWSM-4-407002: Embryonic limit neconns/elimit for through connections exceeded.outside_address/outside_port to global_address (inside_address)/inside_port on interface interface_nameExplanation This message relates to connections through the module and is logged when the number of connections from a specified foreign address over a specified global address to the specified local address exceeds the maximum embryonic limit for that static address. The module attempts to accept the connection if it can allocate memory for that connection. It proxies on behalf of the local host and sends a SYN_ACK packet to the foreign host. The module retains pertinent state information, drops the packet, and waits for the client's acknowledgment.
Recommended Action The traffic might be legitimate, or a denial-of-service (DoS) attack might be in progress. Check the source address to determine where the packets are coming from and whether it is a valid host.
407003
Error Message %FWSM-4-407003: Established limit for RPC services exceeded numberExplanation This message is generated when the FWSM tries to open a new hole for a pair of RPC servers or services that have already been configured after the maximum number of holes has been met.

408002
Error Message %FWSM-4-408002: ospf process id route type update address1 mask1 [distance1/metric1] via source IP:interface1 address2 mask2 [distance2/metric2] interface2Explanation A network update was received from a different interface with the same distance and a better metric than the existing route. The new route overrides the existing route that was installed through another interface. The new route is for redundancy purposes only and means that a path has shifted in the network. This change must be controlled through topology and redistribution. Any existing connections affected by this change are most likely dead and will timeout. This path shift only occurs if the network topology has been specifically designed to support path redundancy, in which case it is expected.
Recommended Action None required.

412001
Error Message %FWSM-4-412001:MAC <mac-address> moved from <interface-1> to <interface-2>Explanation This message is generated when a host move is detected from one module interface to another. In a transparent firewall, mapping between the host (MAC) and firewall port is maintained in a Layer 2 forwarding table. The table dynamically binds packet source MAC addresses to a firewall port. In this process, whenever movement of a host from one interface to another interface is detected, this message is generated.
Recommended Action The host move might be valid or the host move might be an attempt to spoof host MACs on other interfaces. If it is a MAC spoof attempt, you can either locate vulnerable hosts on your network and remove them or configure static MAC entries, which will not allow MAC address and port binding to change. If it is a genuine host move, no action is required.
412002
Error Message %FWSM-4-412002:Detected bridge table full while inserting MAC <mac-address> on interface <interface>. Number of entries = <num>Explanation This message is generated when the bridge table is full and an attempt is made to add one more entry. The FWSM maintains a separate Layer 2 forwarding table per context and the message is generated whenever a context exceeds its size limit. The MAC address will be added, but it will replace the oldest existing dynamic entry (if available) in the table
Recommended Action This might be an attempted attack. Make sure that the new bridge table entries are valid. In case of attack, use EtherType ACLs to access control vulnerable hosts.

This section contains messages from 500003 to 504002.
500003
Error Message %FWSM-5-500003: Bad TCP hdr length (hdrlen=bytes, pktlen=bytes) from source_address/source_port to dest_address/dest_port, flags: tcp_flags, on interface interface_nameExplanation This message indicates that a header length in TCP is incorrect. Some operating systems do not handle TCP resets (RSTs) correctly when responding to a connection request to a disabled socket. If a client tries to connect to an FTP server outside the firewall and FTP is not listening, then the server sends an RST. Some operating systems send incorrect TCP header lengths, which causes this problem. UDP uses ICMP port unreachable messages.
The TCP header length may indicate that it is larger than the packet length, which results in a negative number of bytes being transferred. A negative number is displayed by syslog as an unsigned number, which makes it appear much larger than it would be normally; for example, it may show 4 GB transferred in 1 second.
Recommended Action None required. This message should occur infrequently.
