This section contains messages from 103003 to 199009.

103003

Error Message    %FWSM-1-103003: (Primary) Other firewall network interface 
interface_number failed.

Explanation    This is a failover message. This message is logged if the primary unit detects a bad network interface on the secondary unit. (Primary) can also be listed as (Secondary) for the secondary unit. Refer to Table 1-3 on page 1-11 for possible values for the interface_number variable.

Recommended Action    Check the network connections on the secondary unit and check the network hub connection. If necessary, replace the failed network interface.

103004

Error Message    %FWSM-1-103004: (Primary) Other firewall reports this firewall failed.

Explanation    This is a failover message. This message is logged if the primary unit receives a message from the secondary unit indicating that the primary has failed. (Primary) can also be listed as (Secondary) for the secondary unit.

Recommended Action    Verify the status of the primary unit.

103005

Error Message    %FWSM-1-103005: (Primary) Other firewall reporting failure.

Explanation    This is a failover message. This message is logged if the secondary unit reports a failure to the primary unit. (Primary) can also be listed as (Secondary) for the secondary unit.

Recommended Action    Verify the status of the secondary unit.

104001, 104002

Error Message    %FWSM-1-104001: (Primary) Switching to ACTIVE (cause: string).
Error Message    %FWSM-1-104002: (Primary) Switching to STNDBY (cause: string).

Explanation    Both instances are failover messages. These messages usually are logged when you force the pair to switch roles, either by entering the failover active command on the secondary unit, or the no failover active command on the primary unit. (Primary) can also be listed as (Secondary) for the secondary unit. Possible values for the string variable are as follows:

state check

bad/incompleted config

ifc [interface] check, mate is healthier

the otherside want me standby

in failed state, cannot be active

switch to failed state

Recommended Action    If the message occurs because of manual intervention, no action is required. Otherwise, use the cause reported by the secondary unit to verify the status of both units of the pair.

104003

Error Message    %FWSM-1-104003: (Primary) Switching to FAILED.

Explanation    This is a failover message. This message is logged when the primary unit fails.

Recommended Action    Check the system log messages for the primary unit for an indication of the nature of the problem (see message 104001). (Primary) can also be listed as (Secondary) for the secondary unit.

104004

Error Message    %FWSM-1-104004: (Primary) Switching to OK.

Explanation    This is a failover message. This message is logged when a previously failed unit now reports that it is operating again. (Primary) can also be listed as (Secondary) for the secondary unit.

Recommended Action    None required.

105001

Error Message    %FWSM-1-105001: (Primary) Disabling failover.

Explanation    This is a failover message. This message is logged when you enter the failover command with no arguments on the console, after having previously disabled failover. (Primary) can also be listed as (Secondary) for the secondary unit.

Recommended Action    None required.

105003

Error Message    %FWSM-1-105003: (Primary) Monitoring on interface interface_name 
waiting

Explanation    This is a failover message. The module is testing the specified network interface with the other unit of the failover pair. (Primary) can also be listed as (Secondary) for the secondary unit.

Recommended Action    None required. The firewall monitors its network interfaces frequently during normal operations.

105004

Error Message    %FWSM-1-105004: (Primary) Monitoring on interface interface_name 
normal

Explanation    This is a failover message. The test of the specified network interface was successful. (Primary) can also be listed as (Secondary) for the secondary unit.

Recommended Action    None required.

105005

Error Message    %FWSM-1-105005: (Primary) Lost Failover communications with mate on 
interface interface_name.

Explanation    This is a failover message. This message is logged if this unit of the failover pair can no longer communicate with the other unit of the pair. (Primary) can also be listed as (Secondary) for the secondary unit.

Recommended Action    Verify that the network connected to the specified interface is functioning correctly.

105006, 105007

Error Message    %FWSM-1-105006: (Primary) Link status `Up' on interface 
interface_name.
Error Message    %FWSM-1-105007: (Primary) Link status `Down' on interface 
interface_name.

Explanation    Both instances are failover messages. These messages report the results of monitoring the link status of the specified interface. (Primary) can also be listed as (Secondary) for the secondary unit.

Recommended Action    If the link status is down, verify that the network connected to the specified interface is operating correctly.

105008

Error Message    %FWSM-1-105008: (Primary) Testing interface interface_name.

Explanation    This is a failover message. This message is logged when the module tests a specified network interface. This testing is performed only if the module fails to receive a message from the standby unit on that interface after the expected interval. (Primary) can also be listed as (Secondary) for the secondary unit.

Recommended Action    None required.

105010

Error Message    %FWSM-3-105010: (Primary) Failover message block alloc failed

Explanation    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 mismatch

Explanation    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.

105042

Error Message    %FWSM-1-105042: (Primary) Failover interface OK 

Explanation    Interface used to send failover messages to the secondary module is functioning. (Primary) can also be listed as (Secondary) for the secondary module.

Recommended Action    None required.

105043

Error Message    %FWSM-1-105043: (Primary) Failover interface failed 

Explanation    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_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 FWSM, and it was dropped. The tcp_flags values in this packet are FIN and ACK.

The tcp_flags values 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    %FWSM-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 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_port 

Explanation    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) 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 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_address 

Explanation    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:

Loopback network (127.0.0.0)

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

The destination host (land.c)

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_address 

Explanation    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_address 

Explanation    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_address 

Explanation    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_name 

Explanation    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_name 

Explanation    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_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

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:

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 module 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 interval option.

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_name 

Explanation    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_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 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.

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 nconns 

Explanation    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_name 

Explanation    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 limit 

Explanation    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_addr

Explanation    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/port 

Explanation    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_port 

Explanation    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 code 

Explanation    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 = 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 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 = 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    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 failed

Explanation    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 failed

Explanation    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.

210007

Error Message    %FWSM-3-210007: LU allocate xlate failed

Explanation    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_port 

Explanation    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 updates

Explanation    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 Error

Explanation    Failed to allocate RAM system memory.

Recommended Action    If this message occurs periodically, it can be ignored. If it repeats frequently, contact Cisco TAC.

212002

Error Message    %FWSM-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 FWSM is unable to send its SNMP traps from the module to SNMP management stations located on this interface. This does not affect the SNMP traffic passing through the module through any interface.

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

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

Recommended Action    After the module reclaims some of its resources when traffic is lighter, enter the snmp-server host command for that interface again.

212003

Error Message    %FWSM-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 logged because of an internal error in receiving an SNMP request destined for the module on the specified interface.

Recommended Action    None required. The module SNMP agent goes back to wait for the next SNMP request.

212004

Error Message    %FWSM-3-212004: Unable to send an SNMP response to IP Address 
IP_address Port port interface interface_number, error code = code 

Explanation    This is an SNMP message. This message is logged because of an internal error in sending an SNMP response from the module to the specified host on the specified interface.

Recommended Action    None required.

212005

Error Message    %FWSM-3-212005: incoming SNMP request (number bytes) on interface 
interface_name exceeds data buffer size, discarding this SNMP request.

Explanation    This is an SNMP message. This message reports that the length of the incoming SNMP request which is destined for the module exceeds the size of the internal data buffer (512 bytes) used for storing the request during internal processing. The module is unable to process this request. This situation does not affect the SNMP traffic passing through the module using any interface.

Recommended Action    Have the SNMP management station resend the request with a shorter length. For example, instead of querying multiple MIB variables in one request, try querying only one MIB variable in a request. You may need to modify the configuration of the SNMP manager software.

interface_name:dest_address/dest_port dst 
interface_name:source_address/source_port 

Explanation    A packet does not match any of the outbound nat command rules.

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_port 

Explanation    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 255.255.255.128


The 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_number 

Explanation    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_address 

Explanation    An address translation slot was created. The slot translates the source address from the local side to the global side. In reverse, the slot translatse the destination address from the global side to the local side.

Recommended Action    None required.

305010

Error Message    %FWSM-6-305010: Teardown {dynamic|static} translation from

tries (from IP_address)

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

Recommended Action    The privileged mode password is not necessarily the same as the password for Telnet access to the module. Verify the password and try again.

308002

Error Message    %FWSM-4-308002: static global_address inside_address netmask netmask overlapped with global_address inside_address 

Explanation    This message occurs if 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 statement you specify a host within that range such as 10.1.1.5.

309001

Explanation    The module 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 module.

313001

Error Message    %FWSM-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 module discards the ICMP packet and generates this syslog message. The icmp command enables or disables pinging to an interface. With pinging disabled, the module 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.

313004

Error Message    %FWSM-4-313004:Denied ICMP type=icmp_type, from src_IP_address 
oninterface intf_name to dest_IP_address:no matching session

Explanation    ICMP packets were dropped by the FWSM 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 firewall or ICMP error messages not related to any TCP, UDP, or ICMP session already established in the FWSM.

Recommended Action    None required.

314001

Error Message    %FWSM-6-314001: Pre-allocate RTSP UDP backconnection for

319001

Error Message    %FWSM-3-319001: Acknowledge for arp update for IP address dest_addr 
not received (number).

Explanation    The ARP process in the FWSM lost internal synchronization because the system was overloaded.

Recommended Action    No immediate action is required. The failure is only temporary. Check the average load of the system and make sure it is not used beyond its capabilities.

319002

Error Message    %FWSM-3-319002: Acknowledge for route update for IP address dest_addr 
not received (number).

Explanation    The routing module in the FWSM lost internal synchronization because the system was overloaded.

Recommended Action    No immediate action required. The failure is only temporary. Check the average load of the system and make sure it is not used beyond its capabilities.

319003

Error Message    %FWSM-3-319003: Arp update for IP address address to NPn failed. 

Explanation    When an ARP entry has to be updated, a message is sent to the network processor (NP) in order to update the internal ARP table. If the module is experiencing high utilization of memory or if the internal table is full, the message to the NP may be rejected and this message generated.

Recommended Action    Verify if the ARP table is full. If it is not full, check the load of the module with respect to the CPU utilization and connections per second. If CPU utilization is high and/or there is a large number of connections per second, normal operations will resume when the load returns to normal.

319004

Error Message    %FWSM-3-319004: Route update for IP address dest_addr failed (number).

Explanation    The routing module in the FWSM lost internal synchronization because the system was overloaded.

Recommended Action    None required.

322001

Error Message    %FWSM-3-322001: Deny MAC address mac-address, possible spoof attempt 
on interface interface 

Explanation    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.

322003

Error Message    %FWSM-3-322003: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 not 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 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.

401001

Error Message    %FWSM-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    %FWSM-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    %FWSM-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    %FWSM-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 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 port 

Explanation    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=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.

402102

Error Message    %FWSM-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    %FWSM-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    %FWSM-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 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.

403101

Error Message    %FWSM-4-403101: PPTP session state not established, but received an 
XGRE packet, tunnel_id=number, session_id=number 

Explanation    The module received a PPTP XGRE packet without a corresponding control connection session.

Recommended Action    If this message occurs frequently, report the problem to Cisco TAC.

403102

Error Message    %FWSM-4-403102: PPP virtual interface interface_name rcvd pkt with 
invalid protocol: protocol, reason: reason.

Explanation    The module received an XGRE encapsulated PPP packet with an invalid protocol field.

Recommended Action    If this message occurs frequently, report the problem to Cisco TAC.

403103

Error Message    %FWSM-4-403103: PPP virtual interface max connections reached.

Explanation    The module cannot accept additional PPTP connections.

Recommended Action    None required. Connections are allocated as soon as they are available.

403104

Error Message    %FWSM-4-403104: PPP virtual interface interface_name requires mschap 
for MPPE.

Explanation    The Microsoft Point-to-Point Encryption (MPPE) is configured but MS-CHAP authentication is not.

Recommended Action    Add MS-CHAP authentication with the vpdn group group_name ppp authentication command.

403106

Error Message    %FWSM-4-403106: PPP virtual interface interface_name requires RADIUS 
for MPPE.

Explanation    The MPPE is configured but RADIUS authentication is not.

Recommended Action    Add RADIUS authentication with the vpdn group group_name ppp authentication command.

403107

Error Message    %FWSM-4-403107: PPP virtual interface interface_name missing aaa 
server group info

Explanation    The AAA server configuration information cannot be found.

Recommended Action    Add the AAA server information with the vpdn group group_name client authentication aaa aaa_server_group command.

403108

Error Message    %FWSM-4-403108: PPP virtual interface interface_name missing client ip 
address option

Explanation    The client IP address pool information is missing.

Recommended Action    Add IP address pool information with the vpdn group group_name client configuration address local address_pool_name command.

403109

Error Message    %FWSM-4-403109: Rec'd packet not an PPTP packet. (ip) dest_address= 
dest_address, src_addr= source_address, data: string.

Explanation    The module received a spoofed PPTP packet. This may be a hostile event.

Recommended Action    Contact the peer's administrator to check the PPTP configuration settings.

403110

Error Message    %FWSM-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.

404101

Error Message    %FWSM-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 you specified with the ip local pool command statement.

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

404102

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

Explanation    The module 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.

405101

Error Message    %FWSM-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 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 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 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 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_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 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.

406002

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

Explanation    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_name 

Explanation    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 number 

Explanation    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.

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    %FWSM-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    %FWSM-4-408002: ospf process id route type update address1 mask1 
[distance1/metric1] via source IP:interface1 address2 mask2 [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 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.

409001

Error Message    %FWSM-4-409001: Database scanner: external LSA IP_address netmask is 
lost, reinstalls

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.

Messages 500003 to 504002

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_name 

Explanation    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.

500004

Error Message    %FWSM-4-500004: Invalid transport field for protocol=protocol, from

710002

Error Message    %FWSM-7-710002: {TCP|UDP} access permitted from 
source_address/source_port to interface_name:dest_address/service 

Explanation    For a TCP connection, this message appears when the second TCP packet destined to the module requests to establish a TCP session. This packet is the final ACK of the three-way handshake. This message appears when the respective access control list (Telnet, HTTP, or SSH) has permitted the packet. Also, the SYN cookie verification is successful and the state is reserved for the TCP session.

For a UDP connection, the connection was permitted. For example, this message appears (with the service snmp) when the module receives an SNMP request from an authorized SNMP management station, and the request has been processed. When the service is SNMP, this message occurs a maximum of once every 10 seconds so that the log receiver is not overwhelmed.

Recommended Action    None required.

710003

Error Message    %FWSM-3-710003: {TCP|UDP} access denied by ACL from 
source_address/source_port to interface_name:dest_address/service 

Explanation    This message appears when the module denies an attempt to connect to the interface service. For example, this message appears (with the service SNMP) when the module receives an SNMP request from an unauthorized SNMP management station.

Recommended Action    Use the show http, show ssh, or show telnet command to verify that the module is configured to permit the service access from the host or network. If this message appears frequently, it can indicate an attack.

710005

Error Message    %FWSM-7-710005: {TCP|UDP} request discarded from 
source_address/source_port to interface_name:dest_address/service 

Explanation    This message appears when the module does not have a UDP server that services the UDP request. The message can also indicate a TCP packet that does not belong to any session on the module. In addition, this message appears (with the service SNMP) when the module receives an SNMP request with an empty payload, even if it is from an authorized host. When the service is SNMP, this message occurs a maximum of once every 10 seconds so that the log receiver is not overwhelmed.

Recommended Action    In networks that heavily utilize broadcasting services such as DHCP, RIP or NetBios, the frequency of this message can be high. If this message appears in excessive numbers, it may indicate an attack.
