specified network interface. This testing is performed only if the PIX Firewall 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.
Error Message %PIX-1-105009: (Primary) Testing on interface int_name result.
Explanation This is a failover message. This message reports the result (either "Passed" or "Failed")
of a previous interface test. "(Primary)" can also be listed as "(Secondary)" for the secondary unit.
Recommended Action None required if the result is "Passed." If the result is "Failed," you should
check to be sure the network cable is properly connected to both failover units and that the network
itself is functioning correctly, and verify the status of the standby unit.
Error Message %PIX-3-105010: (Primary) Failover message block alloc failed
Explanation Block memory has been depleted. This is a transient message and the PIX Firewall
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.
Error Message %PIX-1-105011: (Primary) Failover cable communication failure
Explanation The failover cable is not permitting communication between the primary and secondary
units. "(Primary)" can also be listed as "(Secondary)" for the secondary unit.
Recommended Action Ensure that the cable is properly connected.
Error Message %PIX-1-105020: (Primary) Incomplete/slow config replication
Explanation When a failover occurs, the active PIX Firewall 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 PIX Firewall, the PIX Firewall
automatically reloads itself and loads configuration from Flash memory and/or resyncs with
another PIX Firewall. If failovers happen continuously, check the failover configuration and make
sure both PIX Firewall units can communicate with each other.
Messages 106001 to 112001
Error Message %PIX-2-106001: Inbound TCP connection denied from IP_addr/port to
IP_addr/port flags TCP_flags on interface int_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 PIX Firewall, and it was dropped. The
TCP_flags in this packet are FIN,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.
Error Message %PIX-2-106002: protocol Connection denied by outbound list list_ID src
laddr dest faddr
Explanation This is a connection-related message. This message is logged if the specified
connection fails because of an outbound deny command statement. The protocol variable can be
ICMP, TCP, or UDP.
Recommended Action Use the show outbound command to check outbound lists.
Error Message %PIX-2-106006: Deny inbound UDP from faddr/fport to laddr/lport on
interface int_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.
Error Message %PIX-2-106007: Deny inbound UDP from faddr/fport to laddr/lport due
to DNS flag.
Explanation This is a connection-related message. This message is logged if a UDP packet
containing a DNS query or response is denied. The flag variable is either Response or Query.
Recommended Action If the inside port number is 53, it is likely that the inside host is set up as a
caching nameserver. Add an access-list command statement to permit traffic on UDP port 53. If the
outside port number is 53, the most likely cause is that a DNS server was too slow to respond, and
the query was answered by another server.
Error Message %PIX-3-106010: Deny inbound <packet>
Explanation This is a connection-related message. This message is logged if an inbound connection
is denied by your security policy.
Recommended Action None required.
Error Message %PIX-7-106011: Deny inbound (No xlate) chars
Explanation This is a connection-related message. This message occurs when a packet is sent to the
same interface that it arrived on. This usually indicates that a security breach is occurring. When
the PIX Firewall receives a packet, it tries to establish a translation slot based on the security policy
you set with the global and conduit commands, and your routing policy set with the route
command.
Failing both policies, PIX Firewall allows the packet to flow from the higher priority network to a
lower priority network, if it is consistent with the security policy. If a packet comes from a lower
priority network and the security policy does not allow it, PIX Firewall routes the packet back to
the same interface.
To provide access from an interface with a higher security to a lower security, use the nat and
global commands. For example, use the nat command to let inside users access outside servers, to
let inside users access perimeter servers, and to let perimeter users access outside servers.
To provide access from an interface with a lower security to higher security, use the static and
conduit commands. For example, use the static and conduit commands to let outside users access
inside servers, outside users access perimeter servers, or perimeter servers access inside servers.
Recommended Action Fix your configuration to reflect your security policy for handling these attack
events.
Error Message %PIX-2-106012: Deny IP from IP_addr to IP_addr, IP options hex.
Explanation This is a connection-related message. An IP packet was seen with IP options. Because
IP options are considered a security risk, the packet was discarded.
Recommended Action A security breach was probably attempted. Check the local site for loose
source or strict source routing.
Error Message %PIX-2-106013: Dropping echo request from IP_addr to PAT address
IP_Addr
Explanation This message is logged when the PIX Firewall discards an inbound ICMP Echo
Request packet with a destination address that corresponds to a PAT global address. It is discarded
because the inbound packet cannot specify which PAT host should receive the packet.
Recommended Action None required.
Error Message %PIX-3-106014: Deny inbound icmp src interface name: IP_addr dst
interface name: IP_addr (type dec, code dec)
Explanation This message is logged when the PIX Firewall denies any inbound ICMP packet
access. By default, all ICMP packets are denied access unless specifically permitted using the
conduit permit icmp command.
Recommended Action None required.
Error Message %PIX-6-106015: Deny TCP (no connection) from IP_addr/port to
IP_addr/port flags flags on interface int_name.
Explanation This message is logged when the PIX Firewall discards a TCP packet that has no
associated connection in the PIX Firewall unit's connection table. PIX Firewall 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 PIX Firewall discards the packet.
Recommended Action None required unless the PIX Firewall 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.
Error Message %PIX-2-106016: Deny IP spoof from (IP_addr) to IP_addr on interface
int_name.
Explanation This message is logged when the PIX Firewall 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)
Furthermore, if the sysopt connection enforcesubnet command is enabled, PIX Firewall discards packets with a source address belonging to the destination subnet from traversing the PIX Firewall and logs this message.
To further enhance spoof packet detection, use the conduit command to configure the PIX Firewall to discard packets with source addresses belonging to the internal network.
Recommended Action Determine if an external user is trying to compromise the protected network.
Check for misconfigured clients.
Error Message %PIX-2-106017: Deny IP due to Land Attack from IP_addr to IP_addr
Explanation This message appears when PIX Firewall receives a packet with the IP source address
equal to the IP destination, and the destination port equal to the source port. This indicates a
spoofed packet 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.
Error Message %PIX-2-106018: ICMP packet type ICMP_type denied by outbound list
list_ID src laddr dest faddr
Explanation This message is logged because the outgoing ICMP packet with type ICMP_type from
local host laddr to foreign host faddr is denied by outbound list list_ID.
Recommended Action None required.
Error Message %PIX-2-106020: Deny IP teardrop fragment (size = num, offset = num)
from IP_addr to IP_addr
Explanation The PIX Firewall discarded an IP packet with a teardrop signature containing either a
small offset or fragment overlapping. This is a hostile event to circumvent the PIX Firewall or an
Intrusion Detection System.
Recommended Action Contact the remote peer administrator or escalate this issue according to your
security policy.
Error Message %PIX-1-106021: Deny protocol reverse path check from src_addr to
dest_addr on interface int_name
Explanation Someone is attempting to spoof an IP address on an inbound connection. Unicast
Reverse Path Forwarding, also known as reverse route lookup, detected a packet that does not have
a source address represented by a route and assumes it to be part of an attack on your PIX Firewall.
Recommended Action This message appears when you have enabled Unicast Reverse Path
Forwarding with the ip verify reverse-path command. This feature works on packets input to an
interface; if it is configured on the outside, then PIX Firewall checks packets arriving from the
outside.
PIX Firewall looks up a route based on the src_addr. 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, PIX Firewall 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 (in which there is more than one path to a destination. PIX Firewall does not support asymmetric routing.
If configured on an internal interface, PIX Firewall checks static route command statements or RIP and if the src_addr is not found, then an internal user is spoofing their address.
An attack is in progress. With this feature enabled, no user action is required. PIX Firewall repels the attack.
Error Message %PIX-1-106022: Deny protocol connection spoof from src_addr to
dest_addr on interface int_name
Explanation This message only appears if a connection exists and a packet matching the connection
arrives on a different interface than the interface the connection began on.
For example, if a user starts a connection on the inside interface, but the PIX Firewall detects the same connection arriving on a perimeter interface, the PIX Firewall has more than one path to a destination. This is known as asymmetric routing and is not supported on the PIX Firewall.
Alternately, an attacker is attempting to append packets from one connection to another as a way to break into the PIX Firewall. In either case, PIX Firewall displays this message and drops the connection.
Recommended Action This message appears when the ip verify reverse-path command is not
configured. Ensure routing is not asymmetric.
Error Message %PIX-4-106023: Deny protocol src [inbound-interface]:[src_address /
src_port] dst outbound-interface:dst_address / dst_port [type {type}, code
{code}] by access_group access-list-name
Explanation An IP packet was denied by the access-list.
Recommended Action Change permission of access-list if a permit policy is desired. If messages
persist from the same source address, messages could indicate a foot printing or port scanning
attempt. Contact the remote host administrator.
Error Message %PIX-1-107001: RIP auth failed from IP_addr: version=vers, type=type,
mode=mode, sequence=seq on interface int_name
Explanation This is an alert log message. PIX Firewall received a RIP reply message with bad
authentication. This could be due to misconfiguration on the router or the PIX Firewall or it could
be a unsuccessful attempt to attack the PIX Firewall unit's routing table.
Recommended Action This may be an 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 may be trying to deduce the existing keys.
Error Message %PIX-1-107002: RIP pkt failed from IP_addr: version=vers on interface
int_name
Explanation This is an alert message. This could be 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 the
PIX Firewall unit's routing table.
Recommended Action This may be an attack and should be monitored. The packet has passed
authentication, if enabled, and bad data is in the packet. The situation should be monitored and the
keys should be changed if there are any doubts as to the originator of the packet.
Error Message %PIX-2-108002: SMTP replaced chars: out src_addr in laddr data: chars
Explanation This is a Mail Guard (SMTP) message generated by the fixup protocol smtp
command. This message is logged if the PIX Firewall replaces an invalid character in an email
address with a space.
Recommended Action None required.
Error Message %PIX-6-109001: Auth start for user `username' from laddr/lport to
faddr/fport
Explanation This is an AAA message. This message is logged if the PIX Firewall is configured for
AAA and detects an authentication request by the specified user.
Recommended Action None required.
Error Message %PIX-6-109002: Auth from laddr/lport to faddr/fport failed (server
IP_addr failed) on interface int_name.
Explanation This is an AAA message. This message is logged if an authentication request fails
because the specified authentication server cannot be contacted by the PIX Firewall.
Recommended Action Check to be sure the authentication daemon is running on the specified
authentication server.
Error Message %PIX-6-109003: Auth from laddr to faddr/fport failed (all servers
failed) on interface int_name.
Explanation This is an AAA message. This message is logged if no authentication server can be
found.
Recommended Action Ping the authentication server(s) from the PIX Firewall. Make sure the
daemon(s) are running.
Error Message %PIX-6-109005: Authentication succeeded for user `user' from
laddr/lport to faddr/fport on interface int_name.
Explanation This is an AAA message. This message is logged when the specified authentication
request succeeds.
Recommended Action None required.
Error Message %PIX-6-109006: Authentication failed for user `user' from laddr/lport
to faddr/fport on interface int_name.
Explanation This is an AAA message. This message is logged if the specified authentication request
fails, possibly because of a mistyped password.
Recommended Action None required.
Error Message %PIX-6-109007: Authorization permitted for user `user' from
laddr/lport to faddr/fport on interface int_name.
Explanation This is an AAA message. This message is logged when the specified authorization
request succeeds.
Recommended Action None required.
Error Message %PIX-6-109008: Authorization denied for user `user' from faddr/fport
to laddr/lport on interface int_name.
Explanation This is an AAA message. This message is logged if a user is not authorized to access
the specified address, possibly because of a mistyped password.
Recommended Action None required.
Error Message %PIX-6-109009: Authorization denied from laddr/lport to faddr/fport
(not authenticated) on interface int_name.
Explanation This is an AAA message. This message is logged if the PIX Firewall is configured for
AAA and a user attempted to make a TCP connection across the PIX Firewall without prior
authentication.
Recommended Action None required.
Error Message %PIX-3-109010: Auth from laddr/lport to faddr/fport failed (too many
pending auths) on interface int_name.
Explanation This is an AAA message. This message is logged if an authentication request cannot
be processed because the server has too many requests pending.
Recommended Action Check to see if the authentication server is too slow to respond to
authentication requests. Enable Flood Defender with the floodguard enable command.
Error Message %PIX-2-109011: Authen Session Start: user 'user', sid session_num
Explanation An authentication session started between the host and the PIX Firewall and has not yet
completed.
Recommended Action None required.
Error Message %PIX-5-109012: Authen Session End: user 'user', sid session_num,
elapsed num seconds
Explanation The authentication cache has timed out. Users will need to reauthenticate on their next
connection. You can change the duration of this timer with the timeout uauth command.
Recommended Action None required.
Error Message %PIX-3-109013: User must authenticate before using this service
Explanation The user must be authenticated before using the service.
Recommended Action Authenticate using FTP, Telnet, or HTTP before using the service.
Error Message %PIX-7-109014: uauth_lookup_net fail for uauth_in()
Explanation A request to authenticate did not have a corresponding request for authorization.
Recommended Action Ensure that both the aaa authentication and aaa authorization command
statements are included in the configuration.
Error Message %PIX-6-109015: Authorization denied (acl=acl_ID) for user 'username'
from src_addr/src_port to dest_addr/dest_port on interface int_name
Explanation The access list check failed; either it matched a deny, or it matched nothing, such as an
implicit deny. Connection denied by user access list acl_ID, which was defined per the AAA
authorization policy on CiscoSecure ACS.
Recommended Action None required.
Error Message %PIX-3-109016: Can't find authorization ACL acl_ID on 'PIX' for user
'username'
Explanation The AAA authorization access-list command statement ID acl=acl_ID defined on the
remote AAA server has not been configured on the PIX Firewall unit. This error can occur if you
configure the AAA server before configuring the PIX Firewall.
Recommended Action Use the same access-list command statement ID on the PIX Firewall as you
specified on the AAA server.
Error Message %PIX-4-109017: User at IP_addr exceeded auth proxy connection limit
(max %d)\n
Explanation The AAA authorization access-list command statement ID acl=acl_ID defined on the
remote AAA server has not been configured on the PIX Firewall unit. This error can occur if you
configure the AAA server before configuring the PIX Firewall.
Recommended Action None required. If errors persist, this may indicate a possible DoS (denial of
service) attempt.
Error Message %PIX-6-110001: No route to dest_addr from src_addr
Explanation This message indicates a route lookup failure. A packet is looking for a destination
IP address which is not in the routing table.
Recommended Action Check the routing table and make sure there is a route to the destination.
Error Message %PIX-5-111001: Begin configuration: IP_addr writing to device
Explanation This message is logged when you enter the write command to store your configuration
on a device (either floppy, Flash memory, TFTP, the failover standby unit, or the console terminal).
The IP_addr indicates whether the login was made at the console port or via a Telnet connection.
Recommended Action None required.
Error Message %PIX-5-111003: IP_addr Erase configuration
Explanation This is a PIX Firewall management message. This message is logged when you erase
the contents of Flash memory by entering the write erase command at the console. The IP_addr
indicates whether the login was made at the console port or via a Telnet connection.
Recommended Action After erasing the configuration, you must reconfigure the PIX Firewall and
save the new configuration. Alternatively, you can restore information from a configuration that
was previously saved, either on floppy or on a TFTP server elsewhere on the network.
Error Message %PIX-5-111004: IP_addr end configuration: [FAILED]|[OK]
Explanation This message is logged when you enter the config floppy/memory/ network
command, or the write floppy/memory/network/standby command. The IP_addr indicates
whether the login was made at the console port or via a Telnet connection.
Recommended Action None required if the message ends with OK. If the message indicates a failure,
try to fix the problem. For example, if writing to a floppy, ensure that the floppy is not write
protected; if writing to a TFTP server, ensure that the server is up.
Error Message %PIX-5-111005: IP_addr end configuration: OK
Explanation This message is logged when you exit configuration mode. The IP_addr indicates
whether the login was made at the console port or via a Telnet connection.
Recommended Action None required.
Error Message %PIX-5-111006: Console Login from user at IP_addr
Explanation This message is logged when you are successfully authenticated via AAA server to
access the PIX Firewall console. The IP_addr indicates whether the login was made at the console
port or via a Telnet connection.
Recommended Action None required.
Error Message %PIX-5-111007: Begin configuration: IP_addr reading from device.

Error Message %PIX-6-199005: PIX Startup begin
Explanation This message is logged when the PIX Firewall starts.
Recommended Action None required.
Error Message %PIX-3-201002: Too many connections on static|xlate gaddr! econns
nconns
Explanation This is a connection-related message. This message is logged when the maximum
number of connections to the specified static address has been exceeded. The econns variable is the
maximum number of embryonic connections and nconns is the maximum number of connections
permitted for the static or xlate.
Recommended Action Use the show static command to check the limit imposed on connections to a
static address. The limit is configurable.
Error Message %PIX-2-201003: Embryonic limit exceeded neconns/elimit for
faddr/fport (gaddr) laddr/lport on interface int_name
Explanation This is a connection-related message. This message is logged when the maximum
number of embryonic connections from the specified foreign address via the specified static global
address to the specified local address has been exceeded. When the limit on embryonic connections
is reached, the PIX Firewall attempts to accept them anyway, but puts a time limit on the
connections. This allows some connections to succeed even if the PIX Firewall is very busy. The
neconns variable lists the number of embryonic connections received and elimit 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 simply a very heavy load of legitimate traffic. Use the show static
command to check the limit imposed on embryonic connections to a static address.
Error Message %PIX-3-201005: FTP data connection failed for IP_addr
Explanation This is a connection-related message. This message is logged when the PIX Firewall is
unable to 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.
Error Message %PIX-3-201006: RCMD backconnection failed for IP_addr/port
Explanation This is a connection-related message. This message is logged if the PIX Firewall is
unable to preallocate connections for inbound standard output for rsh commands due to insufficient
memory.
Recommended Action Check the rsh client version; the PIX Firewall only supports the Berkeley rsh.
Also, reduce the amount of memory usage, or purchase additional memory.
Error Message %PIX-3-201008: The PIX is disallowing new connections.
Explanation This message occurs when you have enabled TCP syslogging and the syslog server
cannot be reached, or when using PFSS (PIX Firewall Syslog Server) and the disk on the Windows
NT system is full.
Recommended Action Disable TCP syslogging. If using PFSS, free up space on the Windows NT
system where PFSS resides. Also, make sure that the syslog host is up and you can ping the host
from the PIX Firewall console. Then restart TCP syslogging to allow traffic.
Error Message %PIX-3-202001: Out of address translation slots!
Explanation This is a connection-related message. This message is logged if the PIX Firewall 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.
Error Message %PIX-3-202005: Non-embryonic in embryonic list faddr/fport
laddr/lport
Explanation This is a connection-related message. This message is logged when a connection object
(xlate) is in the wrong list.
Recommended Action Contact Customer Support. This should never happen.
Error Message %PIX-3-208005: (function:line_num) pix clear command return
return_code
Explanation The PIX Firewall received a non-zero 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 is most likely due to NFS. Set the read and write size to be the interface MTU for
NFS.
Error Message %PIX-4-209003: Fragment database limit of counts exceeded: src =
IP_addr,
dest = IP_addr, proto = protocol, id = ID
Explanation Too many IP fragments are currently awaiting reassembly. The PIX Firewall limits the
number of IP fragments that can be concurrently reassembled. This restriction prevents memory
depletion at the firewall under abnormal network conditions. In general, fragmented traffic should
be a small percentage of the total traffic mix. A noticeable exception is in the network environment
with NFS over UDP. Consider NFS over TCP in such an environment, if such traffic is to be relayed
through the PIX Firewall. Refer to the fragment command page and the sysopt connection tcpmss
bytes command page in Chapter 5, "Command Reference" of the Configuration Guide for the Cisco
Secure PIX Firewall Version 6.0 for more information.
Recommended Action If this message persists, a DoS (denial of service) attack might be in progress.
Contact the remote peer's administrator or upstream provider.
Error Message %PIX-4-209004: Invalid IP fragment, size = bytes exceeds maximum size
= bytes: src = IP_addr, dest = IP_addr, proto = protocol, id = ID
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.
Error Message %PIX-4-209005: Discard IP fragment set with more than number elements:
src = IP_addr, dest = IP_addr, proto = protocol, id = ID
Explanation Too many elements are in a fragment set. The PIX Firewall disallows any IP packet that
is fragmented into more than 12 fragments. Refer to the fragment command page in Chapter 5,
"Command Reference" of the Configuration Guide for the Cisco Secure PIX Firewall Version 6.0
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.
Messages 210001 to 214001
Error Message %PIX-3-210001: LU SW_Module_Name error = error_code
Explanation This message is logged if a Stateful Failover error occurred.
Recommended Action If this error persists after traffic lessens through the PIX Firewall, report this
error to Customer Support.
Error Message %PIX-3-210002: LU allocate block (size) failed.
Explanation Stateful Failover could not allocate a block of memory to transmit stateful information
to the standby PIX Firewall.
Recommended Action Check the failover interface to make sure its xmit is normal using the show
interface command. 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 PIX Firewall
software to recover the lost blocks of memory.
Error Message %PIX-3-210003: Unknown LU Object ID
Explanation Stateful Failover received an unsupported Logical Update object and therefore was
unable to process it. This could be caused by corrupted memory, LAN transmissions, and other
events.
Recommended Action If you see this error infrequently, then no action is required. If this error occurs
frequently, check the Stateful Failover link LAN connection. If the error was not caused by a faulty
failover link LAN connection, determine if an external user is trying to compromise the protected
network. Check for misconfigured clients.
Error Message %PIX-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 PIX Firewall.
Recommended Action Check the available memory using the show memory command to make sure
the PIX Firewall has free memory in the system. If there is no available memory, add more physical
memory to the PIX Firewall.
Error Message %PIX-3-210006: LU look NAT for IP_addr failed
Explanation Stateful Failover was unable to locate an NAT group for the ip_address on the standby
unit. Most likely, the active and standby PIX Firewall units are out of sync.
Recommended Action Use the write standby command on the active unit to synchronize system
memory with the standby unit.
Error Message %PIX-3-210007: LU allocate xlate failed
Explanation Stateful Failover failed to allocate a translation slot (xlate) record.
Recommended Action Check the available memory by using the show memory command to make
sure the PIX Firewall has free memory in the system. If memory has been used up, you may need
to add more physical memory.
Error Message %PIX-3-210008: LU no xlate for laddr/l_port faddr/f_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.
Error Message %PIX-3-210010: LU make UDP connection for faddr:f_port laddr:l_port
failed
Explanation Stateful Failover was unable to allocate a new record for a UDP connection.
Recommended Action Check the available memory by using the show memory command to make
sure the PIX Firewall has free memory in the system. If memory has been used up, you may need
to add more physical memory.
Error Message %PIX-3-210020: LU PAT port port_number reserve failed
Explanation Stateful Failover is unable to allocate a specific PAT address which is in use.
Recommended Action If this error repeats frequently, use the write standby command on the active
unit to synchronize system memory between the active and standby units.
Error Message %PIX-3-210021: LU create static xlate global_IP ifc int_name failed
Explanation Stateful Failover is unable to create a translation slot (xlate).
Recommended Action If this error repeats frequently, use the write standby command on the active
unit to synchronize system memory between the active and standby units.
Error Message %PIX-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
PIX Firewall units to ensure there is enough memory to process the stateful information. Use the
show failover command to monitor the quality of stateful information updates.
Error Message %PIX-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 Customer Support.
Error Message %PIX-3-211003: CPU utilization for time seconds = %cpu_usage
Explanation This message is displayed if the percentage of CPU usage is greater than 100% for time
seconds.
Recommended Action If this message occurs frequently, contact Customer Support.
Error Message %PIX-3-212001: Unable to open SNMP channel (UDP port udp_port) on
interface interface_number, error code = code
Explanation This is an SNMP message. This message reports that the PIX Firewall is unable to
receive SNMP requests destined for the PIX Firewall from SNMP management stations located on
this interface. This does not affect the SNMP traffic passing through the PIX Firewall via any
interface.
An error code of -1 indicates that PIX Firewall could not open the SNMP transport for the interface.
An error code of -2 indicates that PIX Firewall could not bind the SNMP transport for the interface.
Recommended Action Once the PIX Firewall reclaims some of its resources when traffic is lighter,
use the snmp-server host command for that interface again.
Error Message %PIX-3-212002: Unable to open SNMP trap channel (UDP port udp_port)
on interface interface_number, error code = code
Explanation This is an SNMP message. This message reports that the PIX Firewall will be unable
to send its SNMP traps from the PIX Firewall to SNMP management stations located on this
interface. This does not affect the SNMP traffic passing through the PIX Firewall via any interface.
An error code of -1 indicates that PIX Firewall could not open the SNMP trap transport for the
interface.
An error code of -2 indicates that PIX Firewall could not bind the SNMP trap transport for the interface.
Recommended Action Once the PIX Firewall reclaims some of its resources when traffic is lighter,
issue the snmp-server host command for that interface again.
Error Message %PIX-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 PIX Firewall on the specified interface.
Recommended Action None required. The PIX Firewall SNMP agent will go back to wait for the next
SNMP request.
Error Message %PIX-3-212004: Unable to send an SNMP response to IP Address IP_addr
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 PIX Firewall to the specified host on the specified interface.
Recommended Action None required.
Error Message %PIX-3-212005: incoming SNMP request (number bytes) on interface
int_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, destined for the PIX Firewall, exceeds the size of the internal data buffer (512 bytes) used
for storing the request during internal processing; therefore, PIX Firewall is unable to process this
request. This does not affect the SNMP traffic passing through the PIX Firewall via 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. This may involve modifying the configuration of the SNMP manager
software.
Error Message %PIX-3-213001: PPTP control daemon socket io string, errno = num.
Explanation An internal TCP socket I/O error occurred.
Recommended Action Report the problem to Customer Support.
Error Message %PIX-3-213002: PPTP tunnel hashtable insert failed, peer = IP_addr.
Explanation An internal software error occurred while creating a new PPTP tunnel.
Recommended Action Report the problem to Customer Support.
Error Message %PIX-3-213003: PPP virtual interface number isn't opened.
Explanation An internal software error occurred while closing a PPP virtual interface.
Recommended Action Report the problem to Customer Support.
Error Message %PIX-3-213004: PPP virtual interface number client ip allocation
failed.
Explanation An internal software error occurred while allocating an IP address to the PPTP client.
Recommended Action This error occurs when the IP local address pool has been depleted. Consider
allocating a larger pool with the ip local pool command.
Error Message %PIX-2-214001: Terminating manager session from IP_addr on interface
int_name. Reason: incoming encrypted data (number bytes) longer than
upper_limit_number bytes
Explanation This message is logged when an incoming encrypted data packet destined at the
PIX Firewall management port indicates a packet length exceeding the specified upper limit. This
may be a hostile event. PIX Firewall immediately terminates this management connection.
Recommended Action Ensure that the management connection was initiated by Cisco Secure Policy
Manager.

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 access-list bound to the nat 0 access-list.
Error Message %PIX-3-305006: Regular translation creation failed for protocol src
int_name:IP_addr/port dst int_name:IP_addr/port
Explanation A protocol (UDP, TCP, or ICMP) failed to create a translation through the
PIX Firewall. This message appears as a fix to caveat CSCdr0063 that requested that PIX Firewall
not allow packets destined to network or broadcast addresses. PIX Firewall provides this checking
for addresses that are explicitly identified with static command statements. With the change, for
inbound traffic, PIX Firewall denies translations for a destined IP address identified as a network
or broadcast address.
PIX 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 PIX Firewall will not create an xlate 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 treated as a network address and 10.2.2.255 as the broadcast address. Without an existing xlate, PIX Firewall denies inbound packets destined for 10.2.2.128 or 10.2.2.255, and logs this syslog message.
In case the suspected IP is really a host IP, a separated static command statement with a host mask needs to be configured in front of the subnet static (first match rule for static command statements). The following static causes PIX Firewall to treat 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 xlate may be created by traffic started with the inside host with the questioned IP address. PIX Firewall treats a network or broadcast IP address as a host IP address with overlapped subnet static config, the network address translation for both static command statements must be the same.
Recommended Action This message can be either an internal error or an error in the configuration.
Error Message %PIX-6-305007: Orphan IP IP_addr on interface interface_number
Explanation The PIX Firewall has attempted to translate an address that it cannot find in any of its
global pools. The PIX Firewall assumes that the address has been deleted and drops the request.
Recommended Action None required.
Error Message %PIX-3-305008: Free unallocated global IP address.
Explanation The PIX Firewall 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
PIX Firewall is running a Stateful Failover setup and some of the internal states are momentarily
out of sync between the active and standby unit. This condition is not catastrophic, and the PIX
Firewall will recover automatically.
Recommended Action Report this condition to Customer Support if you continue to see this message.
Error Message %PIX-6-307001: Denied Telnet login session from IP_addr on interface
int_name.
Explanation This is a PIX Firewall management message. The PIX Firewall has denied an attempt
to connect to the Telnet port from the specified IP address on the inside network.
Recommended Action From the console, enter the show telnet command to verify that the PIX
Firewall is configured to permit Telnet access from that host or network.
Error Message %PIX-6-307002: Permitted Telnet login session from IP_addr
Explanation This is a PIX Firewall management message. This message logs a successful Telnet
connection to the PIX Firewall.
Recommended Action None required.
Error Message %PIX-6-307003: telnet login session failed from IP_addr (num attempts)
on interface int_name.
Explanation This is a PIX Firewall management message. The PIX Firewall logs this message after
an incorrect Telnet password was entered num times for the same connection. Up to three attempts
are allowed to log into a console Telnet session.
Recommended Action Verify the password and try again.
Error Message %PIX-4-307004: Telnet session limit exceeded. Connection request from
IP_addr on interface int_name.
Explanation This message is logged when the maximum number of Telnet connections to the
PIX Firewall is exceeded. PIX Firewall denies an attempt to connect to its Telnet port from the
specified IP address on the specified network.
Recommended Action None required.
Error Message %PIX-6-308001: PIX console enable password incorrect for num tries
(from IP_addr).
Explanation This is a PIX Firewall management message. This message is logged after the num
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 PIX Firewall. Verify the password and try again.
Error Message %PIX-4-308002: static gaddr1 laddr1 netmask mask1 overlapped with
gaddr2 laddr2
Explanation This message occurs if the IP addresses in one or more static command statements
overlap. gaddr is the global address, which is the address on the lower security interface and laddr
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, specify a host within
that range such as 10.1.1.5.
Error Message %PIX-3-309001: Denied manager connection from IP_addr.
Explanation This is a PIX Firewall management message. This message is logged when the
PIX Firewall denies an attempt to connect to its management port from the specified IP address.

Recommended Action None required.
Error Message %PIX-6-312001: RIP hdr failed from IP_addr: cmd=cmd, version=vers
domain=name on interface int_name
Explanation PIX Firewall received a RIP message with an operation code other than reply, the
message has a version number different than what is expected on this interface, and the routing
domain entry was non-zero.
Recommended Action This message is informational, but may also indicate that another RIP device
is not configured correctly to communicate with the PIX Firewall.
Error Message %PIX-3-313001: Denied ICMP type=icmp_type, code=type_code from
IP_addr on interface int_name
Explanation When using the icmp command with an access list, if the first matched entry is a permit
entry, ICMP packet continues to be processed. If the first matched entry is a deny entry or an entry
is not matched, PIX Firewall discards the ICMP packet and generates this syslog message. The
icmp command enables or disables pinging to an interface. With pinging disabled, the PIX Firewall
cannot be detected on the network. This feature is also referred to as configurable proxy pinging.
Recommended Action Contact the peer's administrator.
Error Message %PIX-6-314001: Pre-allocate RTSP UDP backconnection for faddr

Error Message %PIX-3-315001: Denied SSH session from IP_addr on interface int_name
Explanation This SSH message logs when the PIX Firewall denies an attempt to connect to the SSH
port from the specified IP address on the specified network interface.
Recommended Action From the console, enter the show ssh command to verify that the PIX Firewall
is configured to permit SSH access from the host or network.
Error Message %PIX-6-315002: Permitted SSH session from IP_addr on interface
int_name for user "user_id"
Explanation This SSH message appears when an SSH session starts. The ip_addr, IP address, is the
address of the host with the SSH client. The int_name, interface name, is the interface through
which the SSH session is started. The user_ID is the username to which the client is accessing. Use
the ssh show sessions command to view the status of SSH sessions. If the user_id is pix, the
connection is to the PIX Firewall console. For example, if host 10.21.196.38 on the outside
interface starts an SSH session to the PIX Firewall console, the message text appears as follows:
%PIX-6-315002: Permitted SSH session from 10.21.196.38 on interface outside for user
"pix"
Recommended Action None required.
Error Message %PIX-6-315003: SSH login session failed from IP_addr on (num attempts)
on interface int_name by user "user_id"
Explanation This SSH message appears after an incorrect user ID or password were entered num
times for the same connection. Up to three attempts are allowed to log into a SSH console session.
The ip_addr, IP address, is the address of the host with the SSH client. The int_name, interface
name, is the interface through which the SSH session is started. The user_ID is the username that
the client is attempting to access. If the user_id is pix, the connection attempt was to the
PIX Firewall console.
Recommended Action If this message appears infrequently, no action is required. If this message
appears frequently, it can indicate an attack. Inform the user to verify their username and password.
Error Message %PIX-3-315004: Fail to establish SSH session because PIX RSA host key
retrieval failed.
Explanation This SSH message appears when the PIX Firewall cannot find the PIX Firewall unit's
RSA host key, which is required for establishing an SSH session. The PIX Firewall host key may
be absent because no PIX Firewall host key has been generated or because the license for this PIX
Firewall does not allow DES or 3DES.
Recommended Action From the console, enter the show ca mypubkey rsa command to verify that
PIX Firewall unit's RSA host key is present. If not, also enter show version to check whether the
PIX Firewall unit's license allows DES or 3DES.
Error Message %PIX-4-315005: SSH session limit exceeded. Connection request from
IP_addr on interface int_name
Explanation This SSH message appears when the maximum number of SSH connections to the
PIX Firewall is exceeded. PIX Firewall denies an attempt to connect to its SSH port from the
specified IP address on the specified network.
Recommended Action None required.
Error Message %PIX-6-315011: SSH session from IP_addr on interface int_name for user
"user_id" terminated normally
Error Message %PIX-6-315011: SSH session from IP_addr on interface int_name for user
"user_id" disconnected by SSH server, reason: "text"
Explanation This message appears after an SSH session completes. If a user enters quit or exit, this
message displays "terminated normally." If the session disconnected for another reason, the text
describes the reason. Table 2-1 lists the possible reasons for why a session disconnected.

Explanation
|
Action
|
Bad checkbytes
|
A mismatch was detected in the check bytes during an SSH key exchange.
|
Restart the SSH session.
|
CRC check failed
|
The CRC value computed for a particular packet does not match the CRC value embedded in the packet; the packet is bad.
|
No action required. If this message persists, call Customer Support.
|
Decryption failure
|
Decryption of an SSH session key failed during an SSH key exchange.
|
Check the RSA host key and try again.
|
Format error
|
A non-protocol version message was received during an SSH version exchange.
|
Check the SSH client, to ensure it is a supported version.
|
Internal error
|
This message indicates either an error internal to SSH on the PIX Firewall or an RSA key may not have been entered on the PIX Firewall or cannot be retrieved.
|
From the PIX Firewall console, enter the show ca mypubkey rsa to verify that RSA host key is present. If not, also enter the show version command to verify whether DES or 3DES is allowed. If an RSA host key is present, just restart the SSH session.
|
Invalid cipher type
|
The SSH client requested an unsupported cipher.
|
Enter the show version command to determine what features your license supports, then reconfigure the SSH client to use the supported cipher.
|
Invalid message length
|
The length of SSH message arriving at the PIX Firewall exceeds 262,144 bytes or is shorter than 4096 bytes. The data may be corrupted.
|
No action required.
|
Invalid message type
|
PIX Firewall received a non-SSH message or an unwanted SSH message.
|
Check whether the peer is an SSH client.
|
Out of memory
|
This message appears when the PIX Firewall is unable to allocate memory for use by the SSH server, probably when the PIX Firewall is busy with high traffic.
|
Restart the SSH session later.
|
Rejected by server
|
User authentication failed.
|
Ask the user to verify their username and password.
|
Reset by client
|
An SSH client sent the SSH_MSG_DISCONNECT message to the PIX Firewall.
|
No action required.
|
status code: hex (hex)
|
Users closed the SSH client window (running on Windows) instead of entering quit or exit at the SSH console.
|
No action required. Encourage users to exit the client gracefully instead of just exiting.
|
Terminated by operator
|
The SSH session was terminated by entering the ssh disconnect command at the PIX Firewall console.
|
No action required.
|
Time-out activated
|
The SSH session timed out because the duration specified by the ssh timeout command was exceeded.
|
No action required. Restart the SSH connection. You can use the ssh timeout command to increase the default value of 5 minutes up to 60 minutes if required.

Error Message %PIX-4-401001: Shuns cleared
Explanation The clear shun command has been issued, to remove existing shuns from memory.
Recommended Action None required. This message is issued to allow an institution to keep a record
of shunning activity.
Error Message %PIX-4-401002: Shun added: IP_addr IP_addr port port
Explanation A shun command has been issued 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 issued to allow an institution to keep a record
of shunning activity.
Error Message %PIX-4-401003: Shun deleted: IP_addr
Explanation A single shunned host has been removed from the shun database.
Recommended Action None required. This message is issued to allow an institution to keep a record
of shunning activity.
Error Message %PIX-4-401004: Shunned packet: IP_addr ==> IP_addr on interface
int_name
Explanation A packet has been 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 will 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-4-401005 can be used to evaluate further risk assessment
concerning this host.
Error Message %PIX-4-401005: Shun add failed: unable to allocate resources for
IP_addr IP_addr port port
Explanation The PIX Firewall is out of memory. A shun was unable to be applied.
Recommended Action The Cisco Secure Intrusion Detection System should continue to attempt to
apply this rule. Attempt to reclaim memory and reapply shun manually, or wait for the Cisco Secure
Intrusion Detection System to do this.
Error Message %PIX-4-402101: decaps: rec'd IPSEC packet has invalid spi for
destaddr=IP_addr, prot=protocol, spi=spi
Explanation Received IPSec packet specifies SPI that does not exist in SADB. This may be a
temporary condition due to slight differences in aging of SAs between the IPSec peers, or it may
be because the local SAs have been cleared. It may also be because of 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.
Otherwise, 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-4-402102: decapsulate: packet missing packet_type,
destadr=dest_addr, actual prot=protocol
Explanation Received IPSec packet 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. packet_type is
either AH or ESP.
Recommended Action Contact the peer's administrator.
Error Message %PIX-4-402103: identity doesn't match negotiated identity (ip)
dest_addr= IP_addr, src_addr= IP_addr, prot= protocol, (ident) local=IP_addr,
remote=IP_addr, local_proxy=IP_addr/IP_addr/port/port,
remote_proxy=IP_addr/IP_addr/port/port
Explanation An unencapsulated IPSec packet does not match the negotiated identity. The peer is
sending other traffic through this security association. It may be due to an security association
selection error by the peer. This may be a hostile event.
Recommended Action Contact the peer's administrator to compare policy settings.
Error Message %PIX-4-402106: Rec'd packet not an IPSEC packet (ip) dest_addr=
IP_addr, src_addr= IP_addr, 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 firewall 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 firewall
interfaces themselves). See messages 307001, 309001, and 315001 for messages that track some
denied sessions.
Recommended Action Contact the peer's administrator to compare policy settings.
Error Message %PIX-4-403101: PPTP session state not established, but received an
XGRE packet, tunnel_id=id, session_id=session
Explanation PIX Firewall received a PPTP XGRE packet without a corresponding control
connection session.
Recommended Action If this message occurs frequently, report the problem to Customer Support.
Error Message %PIX-4-403102: PPP virtual interface int_name rcvd pkt with invalid
protocol: protocol, reason: text.
Explanation PIX Firewall received an XGRE encapsulated PPP packet with an invalid protocol
field.
Recommended Action If this message occurs frequently, report the problem to Customer Support.
Error Message %PIX-4-403103: PPP virtual interface max connections reached.
Explanation PIX Firewall cannot accept additional PPTP connections.
Recommended Action None required. Connections are allocated as soon as they are freed.
Error Message %PIX-4-403104: PPP virtual interface int_name requires mschap for
MPPE.
Explanation The MPPE is configured but MS-CHAP authentication is not.
Recommended Action Add MS-CHAP authentication with the vpdn group group_name ppp
authentication command.
Error Message %PIX-4-403106: PPP virtual interface int_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.
Error Message %PIX-4-403107: PPP virtual interface int_name missing aaa server group
info
Explanation AAA server configuration information cannot be found.
Recommended Action Add AAA server information with the vpdn group group_name client
authentication aaa aaa_server_group command.
Error Message %PIX-4-403108: PPP virtual interface int_name missing client ip
address option
Explanation The client IP address pool information is missing.
Recommended Action Add IP address pool info with the vpdn group group_name client
configuration address local address_pool_name command.
Error Message %PIX-4-403109: Rec'd packet not an PPTP packet. (ip) dest_addr=
IP_addr, src_addr= IP_addr, data: text.
Explanation The PIX Firewall received a spoofed PPTP packet. This may be a hostile event.
Recommended Action Contact the peer's administrator to check the PPTP configuration settings.
Error Message %PIX-4-403110: PPP virtual interface int_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.
Error Message %PIX-4-404101: ISAKMP: Failed to allocate address for client from pool
pool_id
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.
Error Message %PIX-4-405101: Unable to Pre-allocate H225 Call Signalling Connection
for faddr faddr[/fport] to laddr laddr[/lport]
Explanation PIX Firewall 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 Customer Support. 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
xlates and connections. This could also be caused by insufficient memory; reduce the amount of
memory usage, or purchase additional memory.
Error Message %PIX-4-405102: Unable to Pre-allocate H245 Connection for faddr
faddr[/fport] to laddr laddr[/lport]
Explanation PIX Firewall 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 Customer Support. 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
xlates and connections. This could also be caused by insufficient memory; reduce the amount of
memory usage, or purchase additional memory.
Error Message %PIX-4-405103: H225 message from <src_ip/src_port> to
<dest_ip/dest_pot>t contains bad protocol discriminator <hex_value>
Explanation This event is logged when PIX is expecting the protocol discriminator, 0x08, but it
received something other than 0x08. This could happen because the endpoint is sending a bad
packet, or PIX received a message segment other than the first.
Recommended Action Action:Packet is let through since we currently do not handle segments.
Error Message %PIX-4-405104: H225 message received from faddr/fport to laddr/lport
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 PIX Firewall
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 %PIX-4-406001: FTP port command low port: IP_addr/port to IP_addr on
interface int_name
Explanation A client issued an ftp port command and supplied an address other than the address
used in the connection. This is indicative of an attempt to avert the site's security policy.
PIX Firewall drops the packet, terminates the connection, and logs the event.
Recommended Action None required.
Error Message %PIX-4-406002: FTP port command different address: IP_addr(IP_addr)
to IP_addr on interface int_name
Explanation A client issued an ftp port command and supplied a port lesser 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. PIX Firewall drops the packet, terminates the connection, and logs the
event.
Recommended Action None required.
Error Message %PIX-4-407001: Deny traffic for local-host interface:ip_addr, license
limit of count exceeded
Explanation The host limit has been 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 Cisco PIX Firewall within the last five minutes.
–
The inside host currently reserved an xlate connection or user authentication at the Cisco PIX Firewall.
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 Cisco PIX Firewall. To force 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 listed in
Table 2-3.

Error Message %PIX-5-500001: ActiveX content modified src IP_addr dest IP_addr on
interface int_name.
Explanation This message is logged after you turn on the activex option using the filter command,
and the PIX Firewall detects an ActiveX object. The activex option allows the PIX Firewall to filter
out ActiveX contents by modifying it so that it no longer is tagged as an HTML object.
Recommended Action None required.
Error Message %PIX-5-500002: Java content modified src IP_addr dest IP_addr on
interface int_name.
Explanation This message is logged after you turn on the java option using the filter command, and
the PIX Firewall detects an Java applet. The java option allows the PIX Firewall to filter out Java
contents by modifying it so that it no longer is tagged as an HTML object.
Recommended Action None required.
Error Message %PIX-5-500003: Bad TCP hdr length (hdrlen=bytes, pktlen=bytes) from
src_addr/sport to dest_addr/dport, flags: tcp_flags, on interface int_name
Explanation This message indicates that a header length in TCP is incorrect. Some operating
systems do not handle TCP RSTs (resets) correctly when responding to a connection request to a
disabled socket. If a client tries to connect to an FTP server outside the PIX 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 resulting in a negative number of bytes being transferred. A negative number is displayed by syslog as an unsigned number making it appear far larger than would be normal; for example, showing 4 GB transferred in 1 second.
Recommended Action None required. This message should occur infrequently.
Error Message %PIX-4-500004: Invalid transport field for protocol=protocol, from
src_addr/src_port to dest_addr/dest_port
Explanation This message appears when there is an invalid transport number, in which the source
or destination port number for a protocol is zero. The protocol field is 6 for TCP and 17 for UDP.
Recommended Action If these messages persist, contact the peer's administrator.
Error Message %PIX-6-602101: PMTU-D packet packet_length bytes greater than
effective mtu mtu_value dest_addr=dest_ip, src_addr=source_ip, prot=protocol
Explanation This message occurs when the PIX Firewall sends an ICMP destination unreachable
message and when fragmentation is needed, but the "don't-fragment" bit is set.
Recommended Action Ensure that the data is sent correctly.
Error Message %PIX-6-602102: Adjusting IPSec tunnel mtu...
Explanation The MTU for an IPSec tunnel is adjusted from Path MTU Discovery.
Recommended Action Check MTU of the IPSec tunnels. If effective MTU is smaller than normal,
check intermediate links.
Error Message %PIX-6-602301: sa created...
Explanation A new SA (security association) was created.
Explanation Informational message.
Error Message %PIX-6-602302: deleting sa...
Explanation An SA was deleted.
Recommended Action Informational message.
Error Message %PIX-6-603101: PPTP received out of seq or duplicate pkt, tnl_id=id,
sess_id=session, seq=num.
Explanation PIX Firewall received a PPTP packet that was out of sequence or duplicated.
Recommended Action If the packet count is high, contact the peer administrator to check client PPTP
configuration.
Error Message %PIX-6-603102: PPP virtual interface int_name - user: user aaa
authentication started.
Explanation PIX Firewall sent an authentication request to the AAA server.
Recommended Action None required.
Error Message %PIX-6-603103: PPP virtual interface int_name - user: user aaa
authentication status.
Explanation PIX Firewall received an authentication response from the AAA server.
Recommended Action None required.
Error Message %PIX-6-603104: PPTP Tunnel created, tunnel_id is id, remote_peer_ip is
IP_addr, ppp_virtual_interface_id is id, client_dynamic_ip is IP_addr, username is
login, MPPE_key_strength is chars
