message from the secondary unit indicating that the primary has failed. "(Primary)" can be either
Primary or Secondary.
Recommended Action Verify the status of the primary unit.
Log Message %PIX-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 be either Primary or Secondary.
Recommended Action Verify the status of the failover unit with the show failover command.
Log Message %PIX-1-104001: (Primary) Switching to ACTIVE (cause: reason).
Log Message %PIX-1-104002: (Primary) Switching to STNDBY.
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 be either Primary or
Secondary.
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.
Log Message %PIX-1-104003: (Primary) Switching to FAILED.
Explanation This is a failover message. This message is logged when the primary or secondary unit
fails. "(Primary)" can be either Primary or Secondary.
Recommended Action Check the system log messages for the primary unit for an indication of
the nature of the problem (see message 104001).
Log Message %PIX-1-104004: (Primary) Switching to OK.

command with no arguments on the console, after having previously disabled failover. "(Primary)"
can be either Primary or Secondary.
Recommended Action None required.
Log Message %PIX-1-105003: (Primary) Monitoring on interface
interface_number waiting.
Explanation This is a failover message. The PIX Firewall is testing the specified network interface
with the other unit of the failover pair. "(Primary)" can be either Primary or Secondary.
Recommended Action None required. The PIX Firewall monitors its network interfaces
frequently during normal operations.
Log Message %PIX-1-105004: (Primary) Monitoring on interface
interface_number normal.
Explanation This is a failover message. The test of the specified network interface was successful.
"(Primary)" can be either Primary or Secondary.
Recommended Action None required.
Log Message %PIX-1-105005: (Primary) Lost failover communications with mate
on interface interface_number.
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 be either Primary or
Secondary.
Recommended Action Verify that the network connected to the specified interface is functioning
correctly.
Log Message %PIX-1-105006: (Primary) Link status `Up' on interface
interface_number.
Log Message %PIX-1-105007: (Primary) Link status `Down' on interface
interface_number.

the link status of the specified interface. "(Primary)" can be either Primary or Secondary.
Recommended Action If the link status is down, verify that the network connected to the specified
interface is operating correctly.
Log Message %PIX-1-105008: (Primary) Testing interface interface_number.
Explanation This is a failover message. This message is logged when the PIX Firewall tests a
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 be either
Primary or Secondary.
Recommended Action None required.
Log Message %PIX-1-105009: (Primary) Testing interface interface_number
result.
Explanation This is a failover message. This message reports the result (either "pass" or "fail") of
a previous interface test. "(Primary)" can be either Primary or Secondary.
Recommended Action None required if the result is "pass." If the result is "fail," 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.
Log 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 be either Primary or Secondary.
Recommended Action Use the show blocks command to monitor the current block memory.
Log 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 be
either Primary or Secondary.
Recommended Action Once the failover is detected by the PIX Firewall, the PIX Firewall
automatically reloads itself and loads configuration from Flash and/or resyncs with another PIX
Firewall. If failovers happen continuously, check the failover configuration and make sure both PIX
Firewalls can communicate with each other.
Messages 106001 to 112001
Log Message %PIX-2-106001: Inbound TCP connection denied from IP_addr/port
to IP_addr/port flags TCP_flags
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.
Log Message %PIX-2-106002: protocol Connection denied by outbound list
list_ID src laddr lport dest faddr fport
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 is 1 for
ICMP, 6 for TCP, and 17 for UDP. In some 4.4 versions, protocol may also display as the protocol
name; such as, TCP.
For ICMP connections, fport may also be one of the following values corresponding to the ICMP message type:
•0 - Echo Reply
•3 - Destination Unreachable
•4 - Source Quench
•5 - Redirect
•8 - Echo Request
•11 - Time Exceeded
•12 - Parameter Problem
•13/14 - Timestamp Request/Reply
•15/16 - Information Request/Reply
•A1 - Address Format Request
•A2 - Address Format Reply
Recommended Action Use the show outbound command to check outbound lists.
Log Message %PIX-2-106003: Connection denied src laddr dest faddr due to
JAVA Applet.
Explanation This is a connection-related message. This message is logged if JAVA filtering is
enabled, and a JAVA applet is prevented from downloading to a user on the inside network.
Recommended Action Use the show outbound command to check outbound lists for JAVA
access restrictions.
Log Message %PIX-2-106006: Deny inbound UDP from laddr/lport to faddr/fport
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.
Log 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. Set up a conduit for 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 already answered by another
server.
Log Message %PIX-2-106009: Translation for src_addr to dest_addr/dport
denied by outbound (destination is denied) port
Explanation This is a connection-related message. This message is logged if the specified
outbound list prevents an address translation request from being fulfilled. port may also be the ICMP
message type (refer to message %PIX-2-106002 for a list of ICMP message type values).
Recommended Action Use the show outbound command to verify the outbound list.
Log Message %PIX-3-106010: Deny inbound from outside:IP_addr to
inside:IP_addr chars.
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.
Log 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.
Log Message %PIX-2-106012: Deny IP from IP_addr to IP_addr, IP options hex.
Explanation This is a connection-related message. A 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.
Log 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 can not specify which PAT host should receive the packet.
Recommended Action None required.
Log 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.
Log Message %PIX-6-106015: Deny TCP (no connection) from IP_addr/port to
IP_addr/port flags.
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.
Log Message %PIX-2-106016: Deny IP spoof from (IP_addr) to IP_addr
Explanation This message is logged when the PIX Firewall discards a packet with an invalid
source address. Invalid sources addresses are those addresses belonging to (i) loopback network
(127.0.0.0), (ii) broadcast (limited, net-directed, subnet-directed, and all-subnets-directed), or
(iii) the destination host (land.c). Furthermore, if sysopt connection enforcesubnet 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.
Log Message %PIX-2-106017: Packet contains ActiveX content and has been
modified src laddr dest to faddr
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.
Log 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 outgoing ICMP packet with type ICMP_type from
local host lhost to foreign host fhost is denied by outbound list list_ID.
Recommended Action None required.
Log Message %PIX-2-108002: SMTP replaced chars: out src_addr in laddr data:
chars
Explanation This is a Mail Guard (SMTP) message. This message is logged if the PIX Firewall
replaces an invalid character in an email address with a space.
Recommended Action None required.
Log 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.
Log Message %PIX-6-109002: Auth from IP_addr/port to IP_addr/port failed
(server IP_addr failed)
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.
Log Message %PIX-6-109003: Auth from laddr/lport to faddr/fport failed (all
servers failed)
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.
Log Message %PIX-6-109005: Authentication succeeded for user `user' from
laddr/lport to faddr/fport.
Explanation This is an AAA message. This message is logged when the specified authentication
request succeeds.
Recommended Action None required.
Log Message %PIX-6-109006: Authentication failed for user `user' from
laddr/lport to faddr/fport.
Explanation This is an AAA message. This message is logged if the specified authentication
request fails, possibly because of a misstyped password.
Recommended Action None required.
Log Message %PIX-6-109007: Authorization permitted for user `user' from
laddr/lport to faddr/fport.
Explanation This is an AAA message. This message is logged when the specified authorization
request succeeds.
Recommended Action None required.
Log Message %PIX-6-109008: Authorization denied for user `user' from
laddr/lport to faddr/fport.
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 misstyped password.
Recommended Action None required.
Log Message %PIX-6-109009: Authorization denied from laddr/lport to
faddr/fport (not authenticated)
Explanation This is an AAA message. This message is logged if the PIX Firewall is configured for
aaa, and a user attempts to make a TCP connection across the firewall without prior authentication.
Recommended Action None required.
Log Message %PIX-3-109010: Auth from laddr/lport to faddr/fport failed (too
many pending auths)
Explanation This is an AAA message. This message is logged if an authentication request can not
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 floodguard with the floodguard 1 command.
Log 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.
Log Message %PIX-5-109012: Authen Session End: user 'user', sid
session_num, elapsed num_seconds 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.
Log Message %PIX-3-109013: User must authenticate before using this service
Explanation You have not authenticated before using the service.
Recommended Action Authenticate yourself using FTP, Telnet, or HTTP before using the service.
Log 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 provided in the configuration.
Log Message %PIX-3-110002: No ARP for host IP_addr
Explanation This is a routing message. This message is logged if the PIX Firewall cannot resolve
the address of a host on one of its immediately connected networks. This usually occurs if the
specified host does not exist or is not reachable on the network the PIX Firewall expects it to be on,
for example, if the host's address is incorrectly subnetted.
Recommended Action Check to be sure that the host's IP address is appropriate to the network
topology and your subnet scheme. Verify that the host is reachable by pinging it from another host.
Use the show arp command to display the PIX Firewall unit's ARP table. At the very least, the
PIX Firewall must be able to resolve the addresses of its SNMP server, routers, and syslog host.
Log Message %PIX-2-110003: No interface is configured (with nameif).
Explanation This is a routing or interface naming error message. This message is logged if the
specified interface name does not exist. This could occur if you specify an interface that has not yet
been defined with the nameif command, or if you mistype the interface name in a command such as
outbound, static, or conduit.
Recommended Action Check the spelling of the interface parameters in the outbound, static, and
conduit commands. Use the show nameif command to confirm the correct spellings and to verify
that the interface has been defined.
Log Message %PIX-5-111001: Begin configuration: IP_addr writing to device
Explanation This is a PIX Firewall Manager message. This message is logged when a user on the
specified IP_addr host enters the write command to write a configuration to the specified device
(either "floppy," "memory," "net," "standby," or "terminal").
Recommended Action None required.
Log Message %PIX-5-111003: IP_addr erase configuration
Explanation This is a PIX Firewall Manager message. This message is logged when a user at the
specified IP_addr host erases the contents of Flash memory, either by entering the write erase
command at the console, or by clicking OK to clear Flash memory in the PIX Firewall Manager.
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.
Log Message %PIX-5-111004: IP_addr end configuration: [FAILED]|[OK]
Explanation This is a PIX Firewall Manager message. This message is logged when a user on the
specified host IP_addr enters the config floppy/memory/ network command, or the write
floppy/memory/network/standby command.
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.
Log Message %PIX-5-111005: IP_addr end configuration: OK
Explanation This is a PIX Firewall Manager message. This message is logged when a user on the
host specified by IP_addr exits configuration mode.
Recommended Action None required.
Log Message %PIX-5-111006: Console login from user at IP_addr
Explanation This is a PIX Firewall Manager message. This message is logged when the specified
user connects to the PIX Firewall. If authentication is enabled, the username is reported; otherwise,
the string "nobody" appears. The IP_addr indicates whether the login was made at the console port
or via a Telnet connection.
Recommended Action None required.
Log Message %PIX-5-111007: Begin configuration: IP_addr reading from
device.
Explanation This is a PIX Firewall Manager message. This message is logged when a host at the
specified IP_addr enters the reload or configure command to read a configuration from the specified
device (either "floppy," "memory," "net," "standby," or "terminal").
Recommended Action None required.
Log Message %PIX-5-111008: User 'user' executed the 'command' command.
Explanation This message indicates that a command change to the configuration has been made in
an AAA authenticated session.
Recommended Action None required.
Log Message %PIX-2-112001: (chars:dec) pix clear finished
Explanation This is a PIX Firewall Manager message. This message is logged when a request to
clear the PIX Firewall configuration has finished. The source file and line number are identified.
Recommended Action None required.
Messages 199001 to 201008
Log Message %PIX-5-199001: PIX reload command executed from IP_addr.
Explanation This is a PIX Firewall Manager message. This message logs the address of the host
initiating a PIX Firewall reboot with the reload command.
Recommended Action None required.
Log Message %PIX-6-199002: PIX startup completed. Beginning operation.
Explanation This is a PIX Firewall Manager message. This message is logged after the
PIX Firewall finishes its initial boot and Flash memory reading sequence, and is ready to begin
operating normally.
Note If you are using the no logging message command to block syslog messages, note that this message cannot be blocked.
Recommended Action None required.
Log Message %PIX-6-199003: Reducing link MTU dec.
Explanation This is a PIX Firewall Manager message. This message is logged when the
PIX Firewall receives a packet from the outside network that uses a larger MTU than the inside
network. The PIX Firewall then sends an ICMP message to the outside host to negotiate an
appropriate MTU. The log message includes the ICMP message's sequence number.
Recommended Action None required.
Log Message %PIX-6-199005: PIX Startup begin
Explanation This message is logged when the PIX Firewall starts.
Recommended Action None. required.
Log Message %PIX-3-201001: Out of connections! dec/dec.
Explanation This is a connection-related message. This message is logged when the maximum
number of permitted connections has been exceeded. The two numbers reported are current
connections and maximum connections permitted.
Recommended Action First, check inside hosts for runaway processes that are using up too many
connections. The show xlate command may indicate which hosts have requested excessive numbers
of connections. In addition, the PIX Firewall license structure limits the number of permitted
connections. If you need to accommodate more connections, contact your Cisco Systems
representative for a license with a higher connection ceiling.
Log Message %PIX-3-201002: Too many connections on static|xlate gaddr!
econns nconns
Explanation This is a connection-related message. This is a connection-related message. This
message is logged when the maximum number of connections to the specified static address has been
exceeded.
Recommended Action Use the show static command to check the limit imposed on connections
to a static address. The limit is configurable.
Log Message %PIX-2-201003: Embryonic limit exceeded neconns/elimit for
faddr/fport (gaddr) laddr/lport
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.
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.
Log 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.
Log 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.
Log Message %PIX-3-201007: Unable to allocate new udp connections
(faddr/fport-laddr/lport)
Explanation This is a connection-related message. This message is logged if the PIX Firewall
cannot allocate new UDP connections between the specified foreign address and port and the
specified local address and port, due to insufficient memory.
Recommended Action Reduce the amount of memory usage, or purchase additional memory.
Log Message %PIX-3-201008: The PIX is disallowing new connections.
Explanation This message indicates that the PIX Firewall is set to disallow new connections.
Recommended Action None required.
Messages 202001 to 209002
Log 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.
Log Message %PIX-3-202002: getxlate failed int_name.
Explanation The PIX Firewall was unable to find a translation slot for an incoming packet. The
error could occur because the translation slot timeout is set too low, and the slot resource was freed;
or because the specified inside address is not a valid NAT address; or because of a routing problem
(possibly an asymmetric routing loop).
Recommended Action Use the show timeout command to display the translation timeout. Use the
show nat command to determine whether the inside address is a valid destination. Use the show
route command to display the PIX Firewall unit's routing table.
Log Message %PIX-3-202003: Couldn't find xlate gaddr laddr dest_addr
int_name.
Explanation This is a connection-related message, and applies to outbound connections. This
message can occur if an outbound list blocks connections to the specified address, or if the inside
address is not part of a NAT group. A less likely possibility is that there are too many current PAT
connections, and the PIX Firewall cannot allocate a PAT address for the connection.
Recommended Action Use the show outbound command to verify that connections to the
specified address are blocked. Use the show nat command to determine if the inside address is
included in a NAT group. Make sure the global pool is not running out of addresses.
Log Message %PIX-3-202004: Couldn't find xlate gaddr laddr dest_addr
int_name
Explanation This is a connection-related message. This message is logged when a request for a
PAT address failed.
Recommended Action Use the show xlate command to determine if all PAT translation slots are
used up.
Log Message %PIX-3-203001: ESP Error: No Key SPI hex SRC IP_addr DEST
IP_addr
Explanation This is Private Link message. This message is logged if no encryption key could be
found to match the key specified by the remote Private Link unit.
Recommended Action Use the show link command to display information about the keys. If you
recently changed keys, you must change keys on both PIX Firewall units, and you should reboot both
units to activate the new keys.
Log Message %PIX-3-208005: (chars:dec) pix clear command return return_code
Explanation This is a PIX Firewall management message. The PIX Firewall received a non-zero
value (an internal error) when attempting to clear a configuration from 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.
Log Message %PIX-3-209001: IPFRAG: Unable to allocate frag record for
src_addr/src_port to dest_addr/dest_port
Explanation More than 1024 IP fragment packets were received within 10 seconds. PIX Firewall
was unable to allocate a record for each fragment. This could be an indication of a fragment attack
or a host injecting IP fragments, which can occur with NFS when the MTU is set incorrectly.
Recommended Action For performance reasons, the end host should be configured not to inject
IP fragments. Set the read and write size to be the interface MTU for NFS.
Log Message %PIX-3-209002: IPFRAG: First Frag have not been seen
source_host to dest_host
Explanation A noninitial IP fragment was found because either a denial of service attack is
occurring or a remote host is injecting out of order IP fragments, which can occur with NFS. The
source_host is the IP address of the host sending the packet and the dest_host is the host to which
the packet was sent.
Recommended Action For performance reasons, the end host should be configured to not inject
IP fragments. Set the read and write size to be the interface MTU for NFS.
