Error Message %ASA-4-4000nn: IPS:number string from IP_address to IP_address on interface interface_name

Explanation Messages 400000 through 400051 are Cisco Intrusion Prevention Service signature messages.

Recommended Action See the Cisco Intrusion Prevention Service User Guide on Cisco.com.

Not all signature messages are supported by the ASA in this release. IPS messages all start with 4-4000nn and have the following format:

For example:

%ASA-4-400013 IPS:2003 ICMP redirect from 10.4.1.2 to 10.2.1.1 on interface dmz
%ASA-4-400032 IPS:4051 UDP Snork attack from 10.1.1.1 to 192.168.1.1 on interface outside

The following table lists the supported signature messages.

Error Message %ASA-4-401001: Shuns cleared

Explanation The clear shun command was entered to remove existing shuns from memory. An institution to keep a record of shunning activity was allowed.

Recommended Action None required.

Error Message %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. An institution to keep a record of shunning activity was allowed.

Recommended Action None required.

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

ExplanationA single shunned host was removed from the shun database. An institution to keep a record of shunning activity was allowed.

Recommended Action None required.

Error Message %ASA-4-401004: Shunned packet: IP_address = IP_address on interface interface_name

ExplanationA 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. A record of the activity of shunned hosts was provided. This message and message %ASA-4-401005 can be used to evaluate further risk concerning this host.

Recommended Action None required.

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

ExplanationThe ASA is out of memory; a shun cannot be applied.

Recommended ActionThe Cisco IPS should continue to attempt to apply this rule. Try to reclaim memory and reapply a shun manually, or wait for the Cisco IPS to do this.

Error Message%ASA-4-402114: IPSEC: Received an protocol packet (SPI=spi , sequence number=seq_num ) from remote_IP to local_IP with an invalid SPI.

• >protocol— IPsec protocol
• >spi— IPsec Security Parameter Index
• seq_num>— IPsec sequence number
• remote_IP>— IP address of the remote endpoint of the tunnel
• >username— Username associated with the IPsec tunnel
• local_IP>— IP address of the local endpoint of the tunnel

ExplanationAn IPsec packet was received that specifies an SPI that does not exist in the SA database. This may be a temporary condition caused by slight differences in aging of SAs between the IPsec peers, or it may be because the local SAs have been cleared. It may also indicate incorrect packets sent by the IPsec peer, which may be part of an attack. This message is rate limited to no more than one message every five seconds.

Recommended ActionThe 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 connection successfully. Otherwise, if the problem occurs for more than a brief period, either attempt to establish a new connection or contact the peer administrator.

Error Message%ASA-4-402115: IPSEC: Received a packet from remote_IP to local_IP containing act_prot data instead of exp_prot data.

Explanation An IPsec packet was received that is missing the expected ESP header. The peer is sending packets that do not match the negotiated security policy, which may indicate an attack. This message is rate limited to no more than one message every five seconds.

• remote_IP>— IP address of the remote endpoint of the tunnel
• local_IP>— IP address of the local endpoint of the tunnel

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

ExplanationThe 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 use Telnet without IPsec encryption to access the outside interface on port 23, this message appears, but not with Telnet or traffic to the outside interface on ports other than 23. This error can also indicate an attack. This message is not generated except under these conditions (for example, it is not generated for traffic to the ASA interfaces themselves). See messages 710001, 710002, and 710003, which track TCP and UDP requests. This message is rate limited to no more than one message every five seconds.

Make sure that your authentication protocol matches the access concentrator and that your name and password are correct. Verify this information with your ISP or network support person.

Error Message %ASA-3-403504: PPPoE:No 'vpdn group group_name ' 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 ASA for PPPoE dialout. The my-username and my-password commands are used to authenticate the access concentrator, using PAP if necessary.

For example:

ciscoasa# vpdn group my-pppoe request dialout pppoe
ciscoasa# vpdn group my-pppoe ppp authentication pap
ciscoasa# vpdn group my-pppoe localname my-username
ciscoasa# vpdn username my-username password my-password

Explanation You can configure the PPPoE client on an interface to use a particular VPDN group by entering the pppoe client vpdn group group_name command. If a PPPoE VPDN group of the configured name was not located during system startup, this message is generated.

• interface —The interface on which the PPPoE client failed
• group_name —The VPDN group name of the PPPoe client on the interface

Recommended Action Perform the following steps:

1. Add the required VPDN group by entering the vpdn group group_name command. Request dialout PPPoE in global configuration mode, and add all the group properties.
2. Remove the pppoe client vpdn group group_name command from the interface indicated. In this case, the PPPoE client will attempt to use the first PPPoE VPDN group defined.

Note	All changes take effect only after the PPPoE client on the interface is restarted by entering the ip address pppoe command.

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

Explanation The ASA 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 to see if they belong to a valid host.

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

Error Message %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 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. 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. If the problem persists, contact the Cisco TAC.

Error Message %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 ASA 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 translations and connections. In addition, reduce the amount of memory usage, or purchase additional memory. If this message occurs periodically, it can be ignored. If the problem persists, contact the Cisco TAC.

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

Explanation The ASA is expecting the protocol discriminator, 0x08, but it received something other than 0x08. The endpoint may be sending a bad packet, or received a message segment other than the first segment. The packet is allowed through.

Recommended Action None required.

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

Explanation An H.225 message was received out of order, before the initial SETUP message, which is not allowed. The ASA must receive an initial SETUP message for that H.225 call signalling channel before accepting any other H.225 messages.

Recommended Action None required.

Error Message %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 ACF, but the ASA did not send an 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 ASA.

Error Message %ASA-4-405106: H323 num channel is not created from %I/%d to %I/%d %s

Explanation The ASA tried to create a match condition on the H.323 media-type channel. See the match media-type command for more information.

Recommended Action None required.

Error Message %ASA-4-405107: H245 Tunnel is detected and connection dropped from %I/%d to %I/%d %s

Error Message %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 was not the same as the source IP address of the IP packet header.

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

Error Message %ASA-4-405300: Radius Accounting Request received from from_addr is not allowed

Explanation The accounting request came from a host that was not configured in the policy map. The message is logged and processing stops.

• from_addr —The IP address of the host sending the request

Recommended Action If the host was configured to send RADIUS accounting messages to the ASA, make sure that it was configured in the correct policy map that was applied to the service policy. If the host was not configured to send RADIUS accounting messages to the ASA, then check to see why the messages are being sent. If the messages are illegitimate, then create the proper ACLs to drop the packets.

Error Message %ASA-4-405301: Attribute attribute_number does not match for user user_ip

Explanation When the validate-attribute command was entered, the attribute values stored in the accounting request start received do not match those stored in the entry, if it exists.

• attribute_number —The RADIUS attribute to be validated with RADIUS accounting. Values range from 1 to 191. Vendor-specific attributes are not supported.
• user_ip —The IP address (framed IP attribute) of the user.

Recommended Action None required.

Error Message %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 usually devoted to server ports). This is indicative of an attempt to avert the site security policy. The ASA drops the packet, terminates the connection, and logs the event.

Recommended Action None required.

Error Message %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. An attempt to avert the site security policy occurred. For example, an attacker might attempt to hijack an FTP session by changing the packet on the way, and putting different source information instead of the correct source information. The ASA drops the packet, terminates the connection, and logs the event. The address in parentheses is the address from the port command.

Recommended Action None required.

Error Message %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 ASA within the last five minutes.
• The inside host has reserved an xlate connection or user authentication at the ASA.

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 ASA. 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 as given in the table below:

Error Message %ASA-4-407002: Embryonic limit nconns /elimit for through connections exceeded.outside_address /outside_port to global_address (inside_address )/inside_port on interface interface_name

Explanation The number of connections from a specified foreign address over a specified global address to the specified local address exceeded the maximum embryonic limit for that static. The ASA tries 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 ASA retains pertinent state information, drops the packet, and waits for the acknowledgment from the client. The message might indicate legitimate traffic or that a DoS attack is in progress.

Recommended Action Check the source address to determine where the packets are coming from and whether or not a valid host is sending them.

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

Explanation The ASA 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.

Error Message %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 problem persists, contact the Cisco TAC.

Error Message %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 time out. 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.

Error Message %ASA-4-408003: can't track this type of object hex

Explanation A component of the tracking system has encountered an object type that is not supported by the component. A STATE object was expected.

• hex —A hexidecimal value(s) depicting variable value(s) or addresses in memory

Recommended Action Reconfigure the track object to make it a STATE object.

Error Message %ASA-4-408101: KEYMAN : Type encrption_type encryption unknown. Interpreting keystring as literal.

Explanation The format type was not recognized by the system. A keystring format type value of 0 (unencrypted keystring) or 7 (hidden keystring), followed by a space, can precede the actual keystring to indicate its format. An unknown type value will be accepted, but the system will consider the keystring as being unencrypted.

Recommended Action Use the correct format for the value type or remove the space following the value type.

Error Message %ASA-4-408102: KEYMAN : Bad encrypted keystring for key id key_id.

Explanation The system could not successfully decrypt an encrypted keystring. The keystring may have been corrupted during system configuration.

Recommended Action Re-enter the key-string command, and reconfigure the key string.

Error Message %ASA-4-412001:MAC MAC_address moved from interface_1 to interface_2

Explanation A host move was detected from one module interface to another. In a transparent ASA, mapping between the host (MAC) and ASA port is maintained in a Layer 2 forwarding table. The table dynamically binds packet source MAC addresses to an ASA 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 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.

Error Message %ASA-4-412002:Detected bridge table full while inserting MAC MAC_address on interface interface . Number of entries = num

Explanation The bridge table was full and an attempt was made to add one more entry. The ASA 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. This might be an attempted attack.

Recommended Action Make sure that the new bridge table entries are valid. In case of attack, use EtherType ACLs to control access to vulnerable hosts.

Error Message %ASA-4-447001: ASP DP to CP queue_name was full. Queue length length , limit limit

Explanation This message indicates a particular data path (DP) to control point (CP) event queue is full, and one or more multiple enqueue actions have failed. If the event contains a packet block, such as for CP application inspection, the packet will be dropped by the DP, and a counter from the show asp drop command will increment. If the event is for punt to CP, a typical counter is the Punt no memory ASP-drop counter.

• queue —The name of the DP-CP event queue.
• length —The current number of events on the queue.
• limit —The maximum number of events that are allowed on the queue.

Recommended Action The queue-full condition reflects the fact that the load on the CP has exceeded the CP processing ability, which may or may not be a temporary condition. You should consider reducing the feature load on the CP if this message appears repeatedly. Use the show asp event dp-cp command to identify the features that contribute the most load on the event queue.

Error Message %ASA-4-448001: Denied SRTP crypto session setup on flow from src_int :src_ip /src_port to dst_int :dst_ip /dst_port , licensed K8 SRTP crypto session of limit exceeded

Explanation For a K8 platform, the limit of 250 SRTP crypto sessions is enforced. Each pair of SRTP encrypt or decrypt sessions is counted as one SRTP crypto session. A call is counted toward this limit only when encryption or decryption is required for a medium, which means that if the pass-through is set for the call, even if both legs use SRTP, they are not counted toward this limit.

• src_int —The source interface name (inside or outside)
• src_ip —The source IP address
• src_port —The source port
• dst_int —The destination interface name (inside or outside)
• dst_ip —The destination IP address
• dst_port —The destination port
• limit —The K8 limit of SRTP crypto sessions (250)

Recommended Action None required. You can set up new SRTP crypto sessions only when existing SRTP crypto sessions have been released.
