Recommended Action    Once the failover is detected by the security appliance, the security appliance automatically reloads itself and loads configuration from Flash memory and/or resynchronizes with another security appliance. If failovers happen continuously, check the failover configuration and make sure both security appliance units can communicate with each other.

105021

Error Message    %PIX|ASA-1-105021: (failover_unit) Standby unit failed to sync due to 
a locked context_name config. Lock held by lock_owner_name

Explanation    During configuration synchronizing, a standby unit will reload itself if some other process locks the configuration for more than 5 minutes, which prevents the failover process from applying the new configuration. This can occur when an administrator pages through a running configuration on the standby unit while configuration synchronization is in process. See also the show running-config EXEC command and the pager lines num CONFIG command.

Recommended Action    Avoid viewing or modifying configuration on standby unit when it first comes up and is in the process of establishing a failover connection with the active unit.

105031

Error Message    %PIX|ASA-1-105031: Failover LAN interface is up

Recommended Action    Check that the LAN interface cable is connected.

105038

Error Message    %PIX|ASA-1-105038: (Primary) Interface count mismatch

Explanation    When a failover occurs, the active security appliance detects a partial configuration in memory. Normally, this is caused by an interruption in the replication service. (Primary) can also be listed as (Secondary) for the secondary unit.

Recommended Action    Once the failover is detected by the security appliance, the security appliance automatically reloads itself and loads the configuration from Flash memory and/or resyncs with another security appliance. If failovers happen continuously, check the failover configuration and make sure that both security appliance units can communicate with each other.

105039

Error Message    %PIX|ASA-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 security appliances are the same. This message indicates that the primary security appliance is not able to verify the number of interfaces configured on the secondary security appliance. This message indicates that the primary security appliance is not able communicate with the secondary security appliance over the failover interface. (Primary) can also be listed as (Secondary) for the secondary security appliance.

Recommended Action    Verify the failover LAN, interface configuration, and status on the primary and secondary security appliances. Make sure that the secondary security appliance is running the security appliance application and that failover is enabled.

Recommended Action    Make sure that the two failover units are the same.

105047

Error Message    %PIX|ASA-1-105047: Mate has a io_card_name1 card in slot slot_number 
which is different from my io_card_name2

Explanation    The two failover units have different types of cards in their respective slots.

Recommended Action    Make sure that the card configurations for the failover units are the same.

106001

Error Message    %PIX|ASA-2-106001: Inbound TCP connection denied from IP_address/port 
to IP_address/port flags tcp_flags on interface interface_name

Explanation    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 security appliance, and it was dropped. The tcp_flags in this packet are FIN and ACK.

The tcp_flags are as follows:

ACK—The acknowledgment number was received.

FIN—Data was sent.

PSH—The receiver passed data to the application.

RST—The connection was reset.

SYN—Sequence numbers were synchronized to start a connection.

URG—The urgent pointer was declared valid.

Recommended Action    None required.

106002

Error Message    %PIX|ASA-2-106002: protocol Connection denied by outbound list acl_ID 
src inside_address dest outside_address

Explanation    This is a connection-related message. This message is displayed 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    %PIX|ASA-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 displayed if an inbound UDP packet is denied by your security policy.

Recommended Action    None required.

106007

Error Message    %PIX|ASA-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 displayed 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, and a translation entry for the inside. 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    %PIX|ASA-3-106010: Deny inbound protocol src 
interface_name:dest_address/dest_port dst 
interface_name:source_address/source_port

Explanation    This is a connection-related message. This message is displayed 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    %PIX|ASA-3-106011: Deny inbound (No xlate) string

Explanation    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 security appliance 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    %PIX|ASA-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    %PIX|ASA-2-106013: Dropping echo request from IP_address to PAT address 
IP_address

Explanation    The security appliance discarded 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    %PIX|ASA-3-106014: Deny inbound icmp src interface_name: IP_address dst 
interface_name: IP_address (type dec, code dec) 

Explanation    The security appliance denied any inbound ICMP packet access. By default, all ICMP packets are denied access unless specifically permitted.

Recommended Action    None required.

106015

Error Message    %PIX|ASA-6-106015: Deny TCP (no connection) from IP_address/port to 
IP_address/port flags tcp_flags on interface interface_name.

Explanation    The security appliance discarded a TCP packet that has no associated connection in the security appliance's connection table. The security appliance 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 security appliance discards the packet.

Recommended Action    None required unless the security appliance 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    %PIX|ASA-2-106016: Deny IP spoof from (IP_address) to IP_address on 
interface interface_name.

Explanation    The security appliance discarded a packet with an invalid source address.  Invalid source addresses are those addresses belonging to the following:

Loopback network (127.0.0.0)

Broadcast  (limited, net-directed, subnet-directed, and all-subnets-directed)

The destination host (land.c)

To further enhance spoof packet detection, use the conduit command to configure the security appliance to discard packets with source addresses belonging to the internal network. Now that the icmp command has been implemented, the conduit command has been deprecated and is no longer guaranteed to work properly.

Recommended Action    Determine if an external user is trying to compromise the protected network. Check for misconfigured clients.

106017

Error Message    %PIX|ASA-2-106017: Deny IP due to Land Attack from IP_address to 
IP_address

Explanation    The security appliance received 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    %PIX|ASA-2-106018: ICMP packet type ICMP_type denied by outbound list 
acl_ID src inside_address dest outside_address

Explanation    The outgoing ICMP packet with the specified ICMP from local host (inside_address) to the foreign host (outside_address) was denied by the outbound ACL list.

Recommended Action    None required.

106020

Error Message    %PIX|ASA-2-106020: Deny IP teardrop fragment (size = number, offset = 
number) from IP_address to IP_address

Explanation    The security appliance discarded an IP packet with a teardrop signature containing either a small offset or fragment overlapping. This is a hostile event that circumvents the security appliance or an Intrusion Detection System.

Recommended Action    Contact the remote peer administrator or escalate this issue according to your security policy.

106021

Error Message    %PIX|ASA-1-106021: Deny protocol reverse path check from 
source_address to dest_address on interface interface_name

Explanation    An attack is in progress. Someone is attempting to spoof an IP address on an inbound connection. 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 security appliance.

This message appears when you have enabled Unicast RPF with the ip verify reverse-path command. This feature works on packets input to an interface; if it is configured on the outside, then the security appliance checks packets arriving from the outside.

The security appliance looks up a route based on the source_address. If an entry is not found and a route is not defined, then this syslog message appears and the connection is dropped.

If there is a route, the security appliance checks which interface it corresponds to. If the packet arrived on another interface, it is either a spoof or there is an asymmetric routing environment that has more than one path to a destination. The security appliance does not support asymmetric routing.

If the security appliance is configured on an internal interface, it checks static route command statements or RIP, and if the source_address is not found, then an internal user is spoofing their address.

Recommended Action    Even though an attack is in progress, if this feature is enabled, no user action is required. The security appliance repels the attack.

106022

Error Message    %PIX|ASA-1-106022: Deny protocol connection spoof from source_address 
to dest_address on interface interface_name

Explanation    A packet matching a 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 security appliance detects the same connection arriving on a perimeter interface, the security appliance has more than one path to a destination. This is known as asymmetric routing and is not supported on the security appliance.

An attacker also might be attempting to append packets from one connection to another as a way to break into the security appliance. In either case, the security appliance 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    %PIX|ASA-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_ID

Explanation    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    %PIX|ASA-2-106024: Access rules memory exhausted

Explanation    The access list compilation process has run out of memory. All configuration information that has been added since the last successful access list was 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    %PIX|ASA-6-106025: Failed to determine the security context for the 
packet:sourceVlan:source_address dest_address source_port dest_port protocol
Error Message    %PIX|ASA-6-106026: Failed to determine the security context for the 
packet:sourceVlan:source_address dest_address source_port dest_port protocol

Explanation    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    %PIX|ASA-4-106027:Failed to determine the security context for the 
packet:vlansource Vlan#:ethertype src sourceMAC dst destMAC 

Explanation    The security context of the packet in multiple context mode cannot be determined. This message is generated for non-IP packets being dropped in transparent mode only.

Recommended Action    None required.

106100

Error Message    %PIX|ASA-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})

If you configured the log option for the access-list command, the packets matched an ACL statement. 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.

When an access-list line has the log argument, it is expected that this syslog ID might be triggered because of a non-synchronized packet reaching the security appliance and being evaluated by the access-list. For example, if an ACK packet is received on the security appliance (for which no TCP connection exists in the connection table), the device might generate syslog 106100, indicating that the packet was permitted; however, the packet is later correctly dropped because of no matching connection.

The following list describes the message values:

permitted | denied | est-allowed —These values specify if the packet was permitted or denied by the ACL. If the value is est-allowed, the packet was denied by the ACL but was allowed for an already established session (for example, an internal user is allowed to accesss the Internet, and responding packets that would normally be denied by the ACL are accepted).

protocolTCP, UDP, ICMP, or an IP protocol number.

interface_name—The interface name for the source or destination of the logged flow. The VLAN interfaces are supported.

source_address—The source IP address of the logged flow.

dest_address—The destination IP address of the logged flow.

source_port—The source port of the logged flow (TCP or UDP). For ICMP, this field is 0.

dest_port—The destination port of the logged flow (TCP or UDP). For ICMP, this field is icmp-type.

hit-cnt number—The number of times this flow was permitted or denied by this ACL entry in the configured time interval. The value is 1 when the security appliance generates the first syslog message for this flow.

first hit—The first message generated for this flow.

number-second interval—The interval in which the hit count is accumulated. Set this interval using the access-list command with the interval option.

Recommended Action    None required.

106101

Error Message    %PIX|ASA-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 security appliance caches the flow information. This message indicates that the number of matching flows that are cached on the security appliance exceeds the user-configured limit (using the access-list deny-flow-max command).

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    %PIX|ASA-1-107001: RIP auth failed from IP_address: version=number, 
type=string, mode=string, sequence=number on interface interface_name

Explanation    This is an alert log message. The security appliance received a RIP reply message with bad authentication. This message might be caused by a misconfiguration on the router or the security appliance or by an unsuccessful attempt to attack the routing table of the security appliance.

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    %PIX|ASA-1-107002: RIP pkt failed from IP_address: version=number on 
interface interface_name

Explanation    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 security appliance.

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    %PIX|ASA-2-108002: SMTP replaced string: out source_address in 
inside_address data: string

Messages 201002 to 217001

This section contains messages from 201002 to 217001.

201002

Error Message    %PIX|ASA-3-201002: Too many TCP connections on {static|xlate} 
global_address! econns nconns

Explanation    This is a connection-related message. This message is displayed 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    %PIX|ASA-2-201003: Embryonic limit exceeded nconns/elimit for 
outside_address/outside_port (global_address) inside_address/inside_port on interface 
interface_name

Explanation    This is a connection-related message regarding traffic to the security appliance. This message is displayed 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 security appliance is reached, the security appliance attempts to accept them anyway, but puts a time limit on the connections. This situation allows some connections to succeed even if the security appliance 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    %PIX|ASA-3-201004: Too many UDP connections on {static|xlate} 
global_address! udp connections limit

Explanation    This is a connection-related message. This message is displayed 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    %PIX|ASA-3-201005: FTP data connection failed for IP_address IP_address

Explanation    The security appliance could not allocate a structure to track the data connection for FTP because of insufficient memory.

208005

Error Message    %PIX|ASA-3-208005: (function:line_num) clear command return code

Explanation    The security appliance 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 probably due to NFS. Set the read and write size equal to the interface MTU for NFS.

209003

Error Message    %PIX|ASA-4-209003: Fragment database limit of number exceeded: src = 
source_address, dest = dest_address, proto = protocol, id = number

Explanation    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 Cisco Security Appliance Command Reference to raise the maximum). The security appliance limits the number of IP fragments that can be concurrently reassembled. This restriction prevents memory depletion at the security appliance 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 percentage is fragmented traffic; if this type of traffic is relayed through the security appliance, consider using NFS over TCP instead. To prevent fragmentation, see the sysopt connection tcpmss bytes command in the Cisco Security Appliance 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    %PIX|ASA-4-209004: Invalid IP fragment, size = bytes exceeds maximum 
size = bytes: src = source_address, dest = dest_address, proto = protocol, id = number

Explanation    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    %PIX|ASA-4-209005: Discard IP fragment set with more than number 
elements: src = Too many elements are in a fragment set. 

Explanation    The security appliance disallows any IP packet that is fragmented into more than 24 fragments. Refer to the fragment command in the Cisco Security Appliance Command Reference for more information.

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 interface_name command.

210001

Error Message    %PIX|ASA-3-210001: LU sw_module_name error = number

This message reports that the security appliance is unable to receive SNMP requests destined for the security appliance from SNMP management stations located on this interface. This does not affect the SNMP traffic passing through the security appliance through any interface.

An error code of -1 indicates that the security appliance could not open the SNMP transport for the interface. This can occur when the user attempts to change the port on which SNMP accepts queries to one that is already in use by another feature. In this case, the port used by SNMP will be reset to the default port for incoming SNMP queries (UDP/161).

An error code of -2 indicates that the security appliance could not bind the SNMP transport for the interface.

Recommended Action    After the security appliance reclaims some of its resources when traffic is lighter, reenter the snmp-server host command for that interface.

212002

Error Message    %PIX|ASA-3-212002: Unable to open SNMP trap channel (UDP port port) on 
interface interface_number, error code = code

Explanation    This is an SNMP message. This message reports that the security appliance is unable to send its SNMP traps from the security appliance to SNMP management stations located on this interface. This does not affect the SNMP traffic passing through the security appliance through any interface.

An error code of -1 indicates that the security appliance could not open the SNMP trap transport for the interface.

An error code of -2 indicates that the security appliance could not bind the SNMP trap transport for the interface.

Recommended Action    After the security appliance reclaims some of its resources when traffic is lighter, reenter the snmp-server host command for that interface.

212003

Error Message    %PIX|ASA-3-212003: Unable to receive an SNMP request on interface 
interface_number, error code = code, will try again.

Explanation    This is an SNMP message. This message is displayed because of an internal error in receiving an SNMP request destined for the security appliance on the specified interface.

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    %PIX|ASA-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_port

Explanation    A protocol (UDP, TCP, or ICMP) failed to create a translation through the security appliance. This message appears as a fix to caveat CSCdr00663 that requested that security appliance not allow packets that are destined for network or broadcast addresses. The security appliance provides this checking for addresses that are explicitly identified with static command statements. With the change, for inbound traffic, the security appliance denies translations for a destined IP address identified as a network or broadcast address.

The security appliance 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, syslog message 305006 (on the security appliance) is generated.

The security appliance 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 security appliance 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, security appliance denies inbound packets destined for 10.2.2.128 or 10.2.2.255, and logs this syslog 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 security appliance 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 255.255.255.128


The translation may be created by traffic started with the inside host with the questioned IP address. Because the security appliance 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    %PIX|ASA-6-305007: addrpool_free(): Orphan IP IP_address on interface 
interface_number

Explanation    The security appliance has attempted to translate an address that it cannot find in any of its global pools. The security appliance assumes that the address was deleted and drops the request.

Recommended Action    None required.

305008

Error Message    %PIX|ASA-3-305008: Free unallocated global IP address.

Explanation    The security appliance 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 security appliance 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 sync recovers automatically.

Recommended Action    Report this condition to Cisco TAC if you continue to see this message.

305009

Error Message    %PIX|ASA-6-305009: Built {dynamic|static} translation from

Explanation    This is a security appliance management message. This message is displayed after the specified number of times a user incorrectly types the password to enter privileged mode. The maximum is three attempts.

Recommended Action    Verify the password and try again.

308002

Error Message    %PIX|ASA-4-308002: static global_address inside_address netmask netmask 
overlapped with global_address inside_address

Explanation    The IP addresses in one or more static command statements overlap. global_address is the global address, which is the address on the lower security interface, and inside_address is the local address, which is the address on the higher security-level interface.

Recommended Action    Use the show static command to view the static command statements in your configuration and fix the commands that overlap. The most common overlap occurs if you specify a network address such as 10.1.1.0, and in another static command you specify a host within that range such as 10.1.1.5.

version=number domain=string on interface interface_name

Explanation    The security appliance received a RIP message with an operation code other than reply, the message has a version number different from what is expected on this interface, and the routing domain entry was nonzero.

Recommended Action    This message is informational, but it may also indicate that another RIP device is not configured correctly to communicate with the security appliance.

313001

Error Message    %PIX|ASA-3-313001: Denied ICMP type=number, code=code from IP_address 
on interface interface_name

Explanation    When using the icmp command with an access list, if the first matched entry is a permit entry, the ICMP packet continues processing. If the first matched entry is a deny entry or an entry is not matched, the security appliance discards the ICMP packet and generates this syslog message. The icmp command enables or disables pinging to an interface. With pinging disabled, the security appliance cannot be detected on the network. This feature is also referred to as configurable proxy pinging.

Recommended Action    Contact the administrator of the peer device.

313003

Error Message    %PIX|ASA-4-313003: Invalid destination for ICMP error

Explanation    The destination for the ICMP error message is different than the source of the IP packet that induced the ICMP error message.

Recommended Action    If the message occurs frequently, this could be an active network probe, an attempt to use the ICMP error message as a covert channel, or a misbehaving IP host. Contact the administrator of the host that originated the ICMP error message.

313004

Error Message    %PIX|ASA-4-313004:Denied ICMP type=icmp_type, from source_address 
oninterface interface_name to dest_address:no matching session

Explanation    ICMP packets were dropped by the security appliance because of security checks added by the stateful ICMP feature that are usually either ICMP echo replies without a valid echo request already passed across the security appliance or ICMP error messages not related to any TCP, UDP, or ICMP session already established in the security appliance.

Recommended Action    None required.

Error Message    %PIX|ASA-3-322001: Deny MAC address MAC_address, possible spoof 
attempt on interface interface

Explanation    The security appliance 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    %PIX|ASA-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 security appliance. 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.

322003

Error Message    %PIX|ASA-3-322003:ARP inspection check failed for arp 
{request|response} received from host MAC_address on interface interface. This host

bound to any MAC Address. 

Explanation    If the ARP inspection module is enabled, it checks whether a new ARP entry advertised in the packet conforms to the statically configured IP-MAC address binding before forwarding ARP packets across the security appliance. 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.

Error Message    %PIX|ASA-4-401001: Shuns cleared

Explanation    The clear shun command was entered to remove existing shuns from memory.

Recommended Action    None required. This message is displayed to allow an institution to keep a record of shunning activity.

401002

Error Message    %PIX|ASA-4-401002: Shun added: IP_address IP_address port port

Explanation    A shun command was entered, where the first IP address is the shunned host. The other addresses and ports are optional and are used to terminate the connection if available.

Recommended Action    None required. This message is displayed to allow an institution to keep a record of shunning activity.

401003

Error Message    %PIX|ASA-4-401003: Shun deleted: IP_address

Explanation    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    %PIX|ASA-4-401004: Shunned packet: IP_address ==> IP_address on interface 
interface_name

Explanation    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 %PIX|ASA-4-401005 can be used to evaluate further risk assessment concerning this host.

401005

Error Message    %PIX|ASA-4-401005: Shun add failed: unable to allocate resources for 
IP_address IP_address port port

Explanation    The security appliance 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    %PIX|ASA-4-402101: decaps: rec'd IPSEC packet has invalid spi for 
destaddr=dest_address, prot=protocol, spi=number 

Explanation    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.

Error Message    %PIX|ASA-4-402102: decapsulate: packet missing {AH|ESP}, 
destadr=dest_address, actual prot=protocol 

Explanation    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.

Recommended Action    Contact the peer's administrator.

402103

Error Message    %PIX|ASA-4-402103: identity doesn't match negotiated identity (ip) 
dest_address= dest_address, src_addr= source_address, prot= protocol, (ident) 
local=inside_address, remote=remote_address, 
local_proxy=IP_address/IP_address/port/port, 
remote_proxy=IP_address/IP_address/port/port

Explanation    An unencapsulated IPSec packet does not match the negotiated identity. 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    %PIX|ASA-4-402106: Rec'd packet not an IPSEC packet (ip) dest_address= 
dest_address, src_addr= source_address, prot= protocol

Explanation    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 security appliance 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 security appliance 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.

402117

Error Message    %PIX|ASA-4-402117: IPSEC: Received a non-IPSec (protocol) packet from 
remote_IP to local_IP.

Explanation    This message is displayed when 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 firewall may be configured to only accept 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, but not on telnet or traffic to the outside interface on ports other than 23. This error can also indicate an attack. This system log message is not generated except under these conditions (for example, it is not generated for traffic to the firewall interfaces themselves). See messages 710001, 710002, and 710003 for messages that track TCP and UDP requests. This message is rate limited to no more than one message every five seconds

403110

Error Message    %PIX|ASA-4-403110: PPP virtual interface interface_name, user: user 
missing MPPE key from aaa server.

Explanation    The AAA server is not returning the MPPE key attributes required to set up the MPPE encryption policy.

Recommended Action    Check the AAA server configuration and if the AAA server cannot return MPPE key attributes, use local authentication instead with the vpdn group group_name client authentication local command.

403500

Error Message    %PIX|ASA-6-403500: PPPoE - Service name 'any' not received in PADO. 
Intf:interface_name AC:ac_name.

Explanation    The security appliance requested the PPPoE service "any" from the access controller at the Internet service provider. The response from the service provider includes other services but does not include the service "any." This is a discrepancy in the implementation of the protocol. The PADO packet is processed normally and connection negotiations continue.

Recommended Action    None required.

403501

Error Message    %PIX|ASA-3-403501: PPPoE - Bad host-unique in PADO - packet dropped. 
Intf:interface_name AC:ac_name

Explanation    The security appliance sent an identifier called the host-unique value to the access controller. The access controller responded with a different host-unique value. The security appliance is unable to identify the corresponding connection request for this response. The packet is dropped and connection negotiations are discontinued.

Recommended Action    Contact the Internet service provider. Either the access controller at the service provider is mishandling the host-unique value or the PADO packet is being forged.

403502

Error Message    %PIX|ASA-3-403502: PPPoE - Bad host-unique in PADS - dropping packet. 
Intf:interface_name AC:ac_name

Explanation    The security appliance sent an identifier called the host-unique value to the access controller. The access controller responded with a different host-unique value. The security appliance is unable to identify the corresponding connection request for this response. The packet was dropped and connection negotiations were discontinued.

Recommended Action    Contact the Internet service provider. Either the access controller at the service provider is mishandling the host-unique value or the PADO packet is being forged.

403503

Error Message    %PIX|ASA-3-403503: PPPoE:PPP link down:reason 

Explanation    The PPP link has gone down. There are many reasons why this could happen. The first format will display a reason if PPP provides one.

Recommended Action    Check the network link to ensure that the link is connected. The access concentrator could be down. Ensure that your authentication protocol matches the access concentrator. Ensure that your name and password are correct. Check with your ISP or network support person.

403504

Error Message    %PIX|ASA-3-403504: PPPoE:No 'vpdn group' for PPPoE is created

Explanation    PPPoE requires a dial-out configuration before starting a PPPoE session. In general, the configuration should specify a dialing policy, the PPP authentication, the username, and a password. The following example configures the security appliance for PPPoE dialout. The my-username and my-password commands are used to authenticate the access concentrator, using PAP if necessary.

For example:

	vpdn group my-pppoe request dialout pppoe
	vpdn group my-pppoe ppp authentication pap
	vpdn group my-pppoe localname my-username
	vpdn username my-username password my-password
	ip address outside pppoe setroute

Recommended Action    Configure a VPDN group for PPPoE.

403505

Error Message    %PIX|ASA-4-403505: PPPoE:PPP - Unable to set default route to IP_address 
at interface_name

Explanation    This message is usually followed by the message - default route already exists.

Recommended Action    Remove the current default route or remove the "setroute" parameter so that there is no conflict between PPPoE and the manually configured route.

403506

Error Message    %PIX|ASA-4-403506: PPPoE:failed to assign PPP IP_address netmask netmask 
at interface_name

Explanation    This message is followed by - subnet is the same as interface, or on failover channel.

Recommended Action    In the first case, change the address causing the conflict. In the second case, configure the PPPoE on an interface other than the failover interface.

404101

Error Message    %PIX|ASA-4-404101: ISAKMP: Failed to allocate address for client from 
pool string

Explanation    ISAKMP failed to allocate an IP address for the VPN client from the pool that you specified with the ip local pool command.

Recommended Action    Use the ip local pool command to specify additional IP addresses for the pool.

404102

Error Message    %PIX|ASA-3-404102: ISAKMP: Exceeded embryonic limit

Explanation    More than 500 embryonic security associations (SAs) exist, which could mean a DoS attack.

Recommended Action    Enter the show crypto isakmp ca command to determine the origin of the attack. After the source is identified, deny access to the offending IP address or network.

405001

Error Message    %PIX|ASA-4-405001: Received ARP {request | response} collision from 
IP_address/MAC_address on interface interface_name

Explanation    The security appliance received an ARP packet, and the MAC address in the packet differs from the ARP cache entry.

Recommended Action    This traffic might be legitimate, or it might indicate that an ARP poisoning attack is in progress. Check the source MAC address to determine where the packets are coming from and check to see if it belongs to a valid host.

405002

Error Message    %PIX|ASA-4-405002: Received mac mismatch collision from 
IP_address/MAC_address for authenticated host

Explanation    This packet appears for one of the following conditions:

The security appliance received a packet with the same IP address but a different MAC address from one of its uauth entries.

You configured the vpnclient mac-exempt command on the security appliance, and the security appliance receives a packet with an exempt MAC address but a different IP address from the corresponding uauth entry.

Recommended Action    This traffic might be legitimate, or it might indicate that a spoofing attack is in progress. Check the source MAC address and IP address to determine where the packets are coming from and check to see if they belong to a valid host.

405101

Error Message    %PIX|ASA-4-405101: Unable to Pre-allocate H225 Call Signalling 
Connection for foreign_address outside_address[/outside_port] to local_address 
inside_address[/inside_port]

Explanation    The security appliance failed to allocate RAM system memory while starting a connection or 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 xlates and connections. This could also be caused by insufficient memory; reduce the amount of memory usage, or purchase additional memory. If this message occurs periodically, it can be ignored. If it repeats frequently, contact Cisco TAC.

405102

Error Message    %PIX|ASA-4-405102: Unable to Pre-allocate H245 Connection for 
foreign_address outside_address[/outside_port] to local_address 
inside_address[/inside_port]

Explanation    The security appliance failed to allocate RAM system memory while starting a connection or 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 xlates and connections. This could also be caused by insufficient memory; reduce the amount of memory usage, or purchase additional memory. If this message occurs periodically, it can be ignored. If it repeats frequently, contact Cisco TAC.

405103

Error Message    %PIX|ASA-4-405103: H225 message from source_address/source_port to 
dest_address/dest_port contains bad protocol discriminator hex

Explanation    PIX is expecting the protocol discriminator, 0x08, but it received something other than 0x08. This might happen because the endpoint is sending a bad packet, or received a message segment other than the first segment.

Recommended Action    None required. The packet is allowed through.

405104

Error Message    %PIX|ASA-4-405104: H225 message received from outside_address/outside_port 
to inside_address/inside_port before SETUP

Explanation    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 security appliance must receive an initial SETUP message for that H.225 call signalling channel before accepting any other H.225 messages.

Recommended Action    None required.

405105

Error Message    %PIX|ASA-4-405105: H323 RAS message AdmissionConfirm received from 
source_address/source_port to dest_address/dest_port without an AdmissionRequest

Explanation    A gatekeeper has sent an admission confirm (ACF), but the security appliance did not send an admission request (ARQ) to the gatekeeper.

Recommended Action    Check the gatekeeper with the specified source_address to determine why it sent an ACF without receiving an ARQ from the security appliance.

405201

Error Message    %PIX|ASA-4-405201: ILS ILS_message_type from 
inside_interface:source_IP_address to outside_interface:/destination_IP_address has wrong 
embedded address embedded_IP_address

Explanation    The embedded address in the ILS packet payload is not the same as the source IP address of the IP packet header.

Recommended Action    Check the host with the specified with the source_IP_address to determine why it sent an ILS packet with an incorrect embedded IP address.

406001

Error Message    %PIX|ASA-4-406001: FTP port command low port: IP_address/port to 
IP_address on interface interface_name

Explanation    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). This is indicative of an attempt to avert the site's security policy. The security appliance drops the packet, terminates the connection, and logs the event.

Recommended Action    None required.

406002

Error Message    %PIX|ASA-4-406002: FTP port command different address: 
IP_address(IP_address) to IP_address on interface interface_name

Explanation    A client entered 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.

407001

Error Message    %PIX|ASA-4-407001: Deny traffic for local-host 
interface_name:inside_address, license limit of number exceeded

Explanation    The host limit was exceeded. An inside host is counted toward the limit when one of the following conditions is true:

The inside host has forwarded traffic through the security appliance within the last five minutes.

The inside host currently reserved an xlate connection or user authentication at the security appliance.

Recommended Action    The host limit is enforced on the low-end platforms. Use the show version command to view the host limit. Use the show local-host command to view the current active hosts and the inside users that have sessions at the security appliance. To forcefully disconnect one or more users, use the clear local-host command. To expire the inside users more quickly from the limit, set the xlate, connection, and uauth timeouts to the recommended values or lower. (See Table 2-5.)

Table 2-5 Timeouts and Recommended Values

407002

Error Message    %PIX|ASA-3-407002: Embryonic limit nconns/elimit for through connections 
exceeded.outside_address/outside_port to global_address (inside_address)/inside_port on 
interface interface_name

Explanation    This message is about connections through the security appliance. This message is displayed 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. The security appliance attempts to accept the connection if it can allocate memory for that connection. It proxies on behalf of local host and sends a SYN_ACK packet to the foreign host. The security appliance retains pertinent state information, drops the packet, and waits for the client's acknowledgment.

Recommended Action    The message might indicate legitimate traffic, or indicate that a denial of service (DoS) attack is in progress. Check the source address to determine where the packets are coming from and whether it is a valid host.

407003

Error Message    %PIX|ASA-4-407003: Established limit for RPC services exceeded number

Explanation    The security appliance tried 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.

Recommended Action    Wait for other holes to be closed (through associated timeout expiration) or limit the number of active pairs of servers or services.

408001

Error Message    %PIX|ASA-4-408001: IP route counter negative - reason, IP_address 
Attempt: number

Explanation    An attempt to decrement the IP route counter into a negative value failed.

Recommended Action    Enter the clear ip route * command to reset the route counter. If the message continues to appear consistently, copy the messages exactly as they appear, and report it to Cisco TAC.

408002

Error Message    %PIX|ASA-4-408002: ospf process id route type update address1 netmask1 
[distance1/metric1] via source IP:interface1 address2 netmask2 [distance2/metric2] interface2

Explanation    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 probably disabled 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.

409001

Error Message    %PIX|ASA-4-409001: Database scanner: external LSA IP_address netmask is

409003

Error Message    %PIX|ASA-4-409003: Received invalid packet: reason from IP_address, 
interface_name

Explanation    An invalid OSPF packet was received. Details are included in the error message. The cause might be an incorrect OSPF configuration or an internal error in the sender.

Recommended Action    Check the OSPF configuration of the receiver and the sender configuration for inconsistency.

409004

Error Message    %PIX|ASA-4-409004: Received reason from unknown neighbor IP_address

Explanation    The OSPF hello, database description, or database request packet was received, but the router could not identify the sender.

Recommended Action    This situation should correct itself.

409005

Error Message    %PIX|ASA-4-409005: Invalid length number in OSPF packet from IP_address 
(ID IP_address), interface_name

Explanation    The system received an OSPF packet with a field length of less than normal header size or inconsistent with the size of the IP packet in which it arrived. This indicates a configuration error in the sender of the packet.

Recommended Action    From a neighboring address, locate the problem router and reboot it.

409006

Error Message    %PIX|ASA-4-409006: Invalid lsa: reason Type number, LSID IP_address from 
IP_address, IP_address, interface_name

Explanation    The router received an LSA with an invalid LSA type. The cause is either memory corruption or unexpected behavior on a router.

Recommended Action    From a neighboring address, locate the problem router and reboot it. To determine what is causing this problem, contact Cisco TAC for assistance.

409007

Error Message    %PIX|ASA-4-409007: Found LSA with the same host bit set but using 
different mask LSA ID IP_address netmask New: Destination IP_address netmask

409009

Error Message    %PIX|ASA-4-409009: OSPF process number cannot start. There must be at 
least one up IP interface, for OSPF to use as router ID

Explanation    OSPF failed while attempting to allocate a router ID from the IP address of one of its interfaces.

Recommended Action    Make sure that there is at least one interface that is up and has a valid IP address. If there are multiple OSPF processes running on the router, each requires a unique router ID. You must have enough interfaces up so that each of them can obtain a router ID.

409010

Error Message    %PIX|ASA-4-409010: Virtual link information found in non-backbone 
area: string

Explanation    An internal error occurred.

Recommended Action    To determine what is causing this problem, contact Cisco TAC for assistance.
