Introduction

These release notes describe the new features, restrictions, and caveats for Cisco Secure PIX Firewall software version 6.0(4).

System Requirements

The sections that follow list the system requirements for operating a PIX Firewall with version 6.0(4) software.

Memory Requirements


Note All PIX Firewall units must have at least 32 MB of RAM memory or the PIX Firewall will not boot. In addition, all units except the PIX 506/506E must have 16 MB of Flash memory to boot. The PIX 506/506E has 8 MB of memory, which works correctly with version 6.0.


Table 1 lists Flash memory requirements for this release.

Table 1 Flash Memory Requirements

PIX Firewall Model
Flash Memory Required in 6.0

PIX 506/506E

8 MB

PIX 515/515E

16 MB

PIX 520

16 MB (Some PIX 520 units may need a memory upgrade because older units had 2 MB, though newer units have 16 MB.)

PIX 525

16 MB

PIX 535

16 MB


We highly recommend that you use Livengood Gigabit Ethernet cards in systems with a 64-bit/66 MHz PCI bus; for example, in a PIX 535. (If you use the Livengood Gigabit Ethernet cards in a PIX Firewall, the system RAM should be at least 128 MB.) For a PIX Firewall with only a 32-bit/33 MHz bus, such as the PIX 520 and PIX 525, we recommend that you use Wiseman Gigabit Ethernet cards.

Software Requirements

PIX Firewall requires the following for version 6.0(4):

1. The PIX Firewall image no longer fits on a diskette. If you are using a PIX Firewall unit with a diskette drive, you need to download the Boothelper file from Cisco.com to let you download the PIX Firewall image with TFTP.

2. If you are upgrading from version 4 or earlier and want to use the IPSec or VPN features or commands, you must have a new activation key. Before getting a new activation key, write down your old key in case you want to downgrade to version 4. You can have a new activation key sent to you by completing the form at the following website:

http://www.cisco.com/pcgi-bin/Software/FormManager/formgenerator.pl?pid=221&fid=324

3. If you are using PIX Firewall Syslog Server (PFSS), we recommend you install Windows NT Service Pack 6 to fix year 2000 conflicts in Windows NT.

4. If you are upgrading from a previous PIX Firewall version, save your configuration and write down your activation key and serial number. Refer to "Upgrading to a New Software Release" for new installation requirements.

Cisco IOS Software Interoperability

Cisco VPN Series
Interoperability

Cisco IOS Routers

If using IKE mode configuration on the PIX Firewall, the router must be running Cisco IOS Release 12.0(6)T or higher.

Cisco VPN 3000 Concentrators

PIX Firewall version 6.0(1) requires Cisco VPN 3000 Concentrator version 2.5.2 or higher for correct VPN interoperability.


Cisco VPN Client Interoperability

Cisco VPN Client
Interoperability Comments

Cisco Secure VPN Client v1.1

PIX Firewall version 6.0(1) requires Cisco Secure VPN Client version 1.1. Cisco Secure VPN Client version 1.0 and 1.0a are no longer supported.

Cisco VPN 3000 Client v2.5

PIX Firewall version 6.0(1) requires Cisco VPN 3000 Client version 2.5 or higher. This VPN client can be used with Windows 95, Windows 98, and Windows NT version 4.0. It is not supported on Windows 2000.

Cisco VPN Client v3.x

(Unified VPN Client Framework)

PIX Firewall version 6.0(1) supports the Cisco VPN Client version 3.x. The Cisco VPN Client runs on all current Microsoft Windows platforms. At this time, the Cisco VPN Client is not supported on UNIX, Linux, or Mac platforms.


Determining the Software Version

Use the show version command to verify the software version of your PIX Firewall unit.

Upgrading to a New Software Release

If you have a Cisco.com login, you can obtain software from the following website:

http://www.cisco.com/pcgi-bin/tablebuild.pl/pix

New and Changed Information

New Features in Release 6.0(4)

This release resolves a number of caveats. The PIX-4FE-66 card is also supported, except for PIX Classic, 10000 and 510 platforms.

New Features in Release 6.0(3)

This release resolves two caveats, CSCdw63021 and CSCdw75833.

New Features in Release 6.0(2)

The PIX 506E and PIX 515E join the PIX Firewall product line. Both the PIX 506E and PIX 515E have faster processors than the PIX 506 and PIX 515. Also, the PIX 506E has a physically different, but functionally equivalent, power supply than the PIX 506.

New Features in Release 6.0(1)

PIX 535 Interfaces

The PIX 535 now supports up to ten interfaces. A maximum of eight interfaces are available with a restricted license, and ten interfaces are available with an unrestricted license.

These practices must be followed to achieve the best possible system performance on the PIX 535:

PIX-1GE-66 interface cards should be installed first in the 64-bit/66 MHz buses before they are installed in the 32-bit/33 MHz bus. If more than four PIX-1GE-66 cards are needed, they may be installed in the 32-bit/33 MHz bus but with limited potential throughput.

PIX-1GE and PIX-1FE cards should be installed first in the 32-bit/33 MHz bus before they are installed in the 64-bit/66 MHz buses. If more than five PIX-1GE and/or PIX-1FE cards are needed, they may be installed in a 64-bit/66 MHz bus but doing so will lower that bus speed and limit the potential throughput of any PIX-1GE-66 card installed in that bus.

The PIX-1GE Gigabit Ethernet adaptor is supported in the PIX 535; however, its use is strongly discouraged because maximum system performance with the PIX-1GE card is much lower than that with the PIX-1GE-66 card. The software displays a warning at boot time if a PIX-1GE is detected.

Table 2 summarizes the performance considerations of the different interface card combinations.

Table 2 Gigabit Ethernet Interface Card Combinations

Interface Card Combination
Installed in Interface Slot Numbers
Potential Throughput

Two to four PIX-1GE-66

0 through 3

Best

PIX-1GE-66 combined with PIX-1GE or just PIX-1GE cards

0 through 3

Degraded

Any PIX-1GE-66 or PIX-1GE

4 through 8

Severely degraded



Caution The PIX-4FE and PIX-VPN-ACCEL cards can only be installed in the 32-bit/33 MHz bus and must never be installed in a 64-bit/66 MHz bus. Installation of these cards in a 64-bit/66 MHz bus may cause the system to hang at boot time.


Caution If Stateful Failover is enabled, the interface card and bus used for the Stateful Failover LAN port must be equal to or faster than the fastest card used for the network interface ports. For example, if your inside and outside interfaces are PIX-1GE-66 cards installed in bus 0, then your Stateful Failover interface must be a PIX-1GE-66 card installed in bus 1. A PIX-1GE or PIX-1FE card cannot be used in this case, nor can a PIX-1GE-66 card installed in bus 2 or sharing bus 1 with a slower card.

Changed Hardware Features in Release 6.0(1)


Note The PIX Firewall Classic, PIX10000, and PIX 510 platforms are not supported on version 6.0(1).


New Software Features in Release 6.0(1)

AAA—Authentication, Authorization, and Accounting

The aaa authentication command has been modified to support HTTP authentication. The PIX Firewall allows authentication verification of the HTTP server through the aaa authentication http console command before PDM can access the PIX Firewall. More information about this command is available in the "Command Reference" section.

Cisco VPN Client Version 3.x

PIX Firewall software versions 6.0(1) and higher support the Cisco VPN Client version 3.x. The Cisco VPN Client is a cross-platform Virtual Private Network (VPN) client.

CiscoView Support

The existing MIB II support on PIX Firewall version 6.0(1) has been enhanced to provide PIX Firewall platform-specific Object ID in the SNMP mib-2.system.sysObjectID variable.

The SNMP mib-2.system.sysObjectID variable now provides one of the following PIX Firewall platform-specific Object IDs:

.iso.org.dod.internet.private.enterprises.cisco.ciscoProducts.ciscoPIXFirewa ll506 (same 
as .1.3.6.1.4.1.9.1.389)
.iso.org.dod.internet.private.enterprises.cisco.ciscoProducts.ciscoPIXFirewa ll515 (same 
as .1.3.6.1.4.1.9.1.390)
.iso.org.dod.internet.private.enterprises.cisco.ciscoProducts.ciscoPIXFirewa ll520 (same 
as .1.3.6.1.4.1.9.1.391)
.iso.org.dod.internet.private.enterprises.cisco.ciscoProducts.ciscoPIXFirewa ll525 (same 
as .1.3.6.1.4.1.9.1.392)
.iso.org.dod.internet.private.enterprises.cisco.ciscoProducts.ciscoPIXFirewa ll535 (same 
as .1.3.6.1.4.1.9.1.393)

For other PIX Firewall platforms not mentioned in the preceding text:

.iso.org.dod.internet.private.enterprises.cisco.ciscoProducts.ciscoPIXFirewa
ll (same as .1.3.6.1.4.1.9.1.227)

clear logging Command

The clear logging command now works in privileged mode. More information about this command is available in the "Command Reference" section.

CPU Utilization Monitoring

The show cpu usage command has been added to the PIX Firewall for CPU Utilization monitoring support. More information about this command is available in the "Command Reference" section.

DHCP Support

The PIX Firewall Dynamic Host Configuration Protocol (DHCP) client/server support has been extended to let the user automatically leverage the DNS, WINS, and domain name values obtained by the
PIX Firewall DHCP client for use by the hosts served by the DHCP server.

The following commands have been modified or added to the PIX Firewall to provide DHCP client/server support:

ip address

dhcpd

The ip address command has been enhanced to let you enter the number of times the PIX Firewall will poll for DHCP information. Refer to the "Command Reference" section for more information.

Failover Support for HTTP

For PIX Firewall version 6.0(1), the following commands have been modified or added to the PIX Firewall to allow the stateful replication of HTTP sessions in a Stateful Failover environment:

failover replicate http

show failover

When HTTP replication is enabled, the show failover command displays the failover replicate http command.

Refer to the "Command Reference" section for more information.

fragment Command

The fragment command provides additional management of packet fragmentation and improves compatibility with NFS. Refer to the "Command Reference" section for more information.

L2TP—Layer 2 Tunnel Protocol

Layer 2 Tunneling Protocol (L2TP) is a Virtual Private Network (VPN) tunneling protocol that allows remote clients to use public networks to communicate securely with servers at private corporate networks.

PIX Firewall version 6.0(1) supports terminating the Microsoft Windows 2000 OS L2TP/IPSec client. This feature does not work with L2TP/IPSec clients from other vendors. L2TP traffic must be protected by the IPSec traffic, or the PIX Firewall will discard unsecured L2TP traffic.

The following commands have been modified or added to the PIX Firewall to provide L2TP support:

debug ppp

show vpdn

sysopt connection permit

vpdn group

crypto ipsec transform-set

Refer to the "Command Reference" section for more information.

Cisco PIX Device Manager (PDM)

The Cisco PIX Device Manager (PDM) is a browser-based configuration tool designed to help you set up, configure, and monitor your PIX Firewall graphically, without requiring an extensive knowledge of the PIX Firewall command-line interface (CLI). PDM ships with every PIX Firewall running software version 6.0(1) and higher.

The following commands have been modified or added to the PIX Firewall to provide this PDM support:

aaa authentication

clear logging

copy tftp flash

http

pdm

setup

Refer to the "Command Reference" section for more information.

Port Redirection

The PIX Firewall now provides static Port Address Translation (PAT) capability. This capability can be used to send multiple inbound TCP or UDP services to different internal hosts through a single global address. The global address can be a unique address, a shared outbound PAT, or shared with the external interface.

The static command has been modified to accommodate this feature. Refer to the "Command Reference" section for more information.

RADIUS Support

Two new aaa-server command options now support selection of RADIUS accounting and authentication ports. More information about this command is available in the "Command Reference" section.


Note The Release Notes for the Cisco Secure PIX Firewall Version 5.3.1 contained an error which included two sysopt command options, sysopt radius acct-port and sysopt radius auth-port, as performing this function. Those commands were not implemented and do not exist in version 5.3.1 or any other release.


show interface Command

The show interface command has been modified to display buffer counters. Refer to the "Command Reference" section for more information.

shun Command

The shun command, when issued from an appropriately configured Cisco Secure IDS unit (PIX Firewall shunning is supported in Cisco Secure IDS 3.0), provides dynamic packet filtering in response to a Cisco Secure IDS signature by preventing new connections from an attacking host and disallowing packets from the attacking host on any existing connection(s). When possible, the connection that caused the event is terminated. More information about this command is available in the "Command Reference" section.

SNMP Enhancements

Support for the PIX Firewall platform-specific object IDs has been added to the SNMP mib-2.system.sysObjectID variable. This enhancement is necessary for CiscoView Support of the PIX Firewall.

PIX Firewall version 6.0(1) supports up to 32 SNMP management stations.

Two new options have been added to the snmp-server host command to support specific configuration of trap and poll activities. Refer to the "Command Reference" section for more information.

SSL debug Support

Support for the Secure Socket Layer (SSL) protocol has been added to the debug command. SSL is a protocol for authenticated and encrypted communications between client and servers such as the Cisco PIX Device Manager (PDM) and the PIX Firewall. Refer to the "Debug Commands" section for more information.

Voice Over IP Skinny Protocol Support

The fixup protocol command has been enhanced to support the Skinny Client Control Protocol (SCCP), used for IP telephony.

Refer to the "Command Reference" section for more information.

Command Reference

This section documents new or modified commands in version 6.0(1). All other commands used with this version are documented in the Cisco PIX Firewall Configuration Guide, Version 6.0.

aaa authentication

The aaa authentication command has been modified to support PDM authentication. The PIX Firewall allows authentication verification of the HTTP server through the aaa authentication http console command before PDM can access the PIX Firewall.

[no] aaa authentication [serial | enable | telnet | ssh | http] console group_tag

Syntax Description

authentication

Enable or disable user authentication, prompt user for username and password, and verify information with the authentication server.

serial

Access verification for the PIX Firewall unit's serial console.

enable

Access verification for the PIX Firewall unit's privilege mode.

telnet

Access verification for the Telnet access to the PIX Firewall console.

ssh

Access verification for the SSH access to the PIX Firewall console.

http

Access verification for the Hypertext Transfer Protocol (HTTP) access to the PIX Firewall (via PDM).

console

Specifies that access to the PIX Firewall console requires authentication.

group_tag

The AAA server group tag defined by the aaa-server command.


Defaults

If an aaa authentication http console group_tag command statement is not defined, you can gain access to the PIX Firewall (via PDM) with no username and the PIX Firewall enable password (set with the password command). If the aaa command is defined but the HTTP authentication requests a time out, which implies the AAA servers may be down or not available, you can gain access to the PIX Firewall using the username pix and the enable password (set with the enable password command).

Use of the aaa authentication command requires that you previously used the aaa-server command to designate an authentication server.

The web browser prompts for the username and password with a pop-up window.

Examples

	router(config) aaa authentication telnet console radius

Related Commands

aaa-server

http

setup

aaa-server

Two new aaa-server commands, aaa-server radius-authport and aaa-server radius-acctport, have been added to support selection of the RADIUS server ports, which will be used for authentication and accounting.

aaa-server radius-authport port
aaa-server radius-acctport port


Note sysopt radius acct-port and sysopt radius auth-port, documented in Release Notes for the Cisco Secure PIX Firewall Version 5.3.1 were in error. Those commands do not exist.


Syntax Description

radius-authport

Sets the port number of the RADIUS server which the PIX Firewall will use for authentication functions. The default port number used for RADIUS authentication is 1645.

radius-acctport

Sets the port number of the RADIUS server which the PIX Firewall unit will use for accounting functions. The default port number used for RADIUS accounting is 1646.

port

Specifies the destination TCP/UDP port number of the remote RADIUS server host to which you wish to assign authentication or accounting functions for the PIX Firewall.

These port pairs are listed as assigned to authentication and accounting services on RADIUS servers:

1645 (authentication), 1646 (accounting) - default for PIX Firewall

1812 (authentication), 1813 (accounting) - alternate

You can view these and other commonly used port number assignments online at the following website:

http://www.iana.org/assignments/port-numbers


Defaults

By default, the PIX Firewall listens for RADIUS on ports 1645 for authentication and 1646 for accounting.

Usage Guidelines

If your RADIUS server uses ports 1812 for authentication and 1813 for accounting, you are required to reconfigure the PIX Firewall to use ports 1812 and 1813.


Note This is a global setting that takes effect when RADIUS service is started. The default ports are 1645 for authentication and 1646 for accounting as defined in RFC 2058. Newer RADIUS servers may use the port numbers 1812 and 1813 as defined in RFC 2138 and 2139. If your server uses ports other than 1645 and 1646, then you should define ports using the aaa-server radius-authport and aaa-server radius-acctport commands prior to starting the RADIUS service with the aaa-server command.


Examples

aaa-server radius-authport 1812 
aaa-server radius-acctport 1813

clear logging

The clear logging command clears the syslog message queue accumulated by the logging buffered command. New to version 6.0(1), the clear logging command is now permitted in privileged mode.

clear logging

Examples

clear logging

copy tftp flash

This command has been enhanced to lets you to copy a PDM image to Flash memory using TFTP.

copy tftp[:[[//location] [/pathname]]] flash[:[image | pdm]]

Syntax Description

copy tftp flash

Download Flash memory software images via TFTP without using monitor mode.

location

Either an IP address or a name that resolves to an IP address via the PIX Firewall naming resolution mechanism.

pathname

PIX Firewall must know how to reach this location via its routing table information. This information is determined by the ip address command, the route command, or also RIP, depending upon your configuration. The pathname can include any directory names in addition to the actual last component of the path to the file on the server.

image

Download the selected PIX Firewall image to Flash memory. An image you download is made available to the PIX Firewall on the next reload (reboot).

pdm

Download the selected PDM image files to Flash memory. These files are available to the PIX Firewall immediately, without a reboot.


Defaults

If the pdm image type is not specified, the default copies the PIX Firewall image.

Examples

copying tftp://171.69.38.195/cdisk to flash

setup

crypto ipsec transform-set

For PIX Firewall version 6.0(1), L2TP is the only protocol that can use the IPSec transport mode. PIX Firewall discards all other types of packets using IPSec transport mode.

crypto ipsec transform-set trans-name mode transport

Syntax Description

crypto ipsec transform-set

A transform set specifies one or two IPSec security protocols (either Encapsulating Security Payload (ESP) or Authentication Header (AH) or both) and specifies which algorithms to use with the selected security protocol. During the IPSec security association negotiation, the peers agree to use a particular transform set when protecting a particular data flow.

trans-name

IPSec transform set name.

mode

Specify IPSec transport mode for a transform set.

transport

Windows 2000 L2TP/IPSec client uses IPSec transport mode, so you need to select transport mode on the transform set.


Usage Guidelines

A transport-mode transform can only be used on a dynamic crypto map and causes the PIX Firewall to fail if you attempt to tie a transport-mode transform to a static crypto map.

Examples

crypto ipsec transform-set myset mode transport

dhcpd

Dynamic Host Configuration Protocol (DHCP) client/server support has been extended to let the user automatically leverage the DNS, WINS and domain name values obtained by the PIX Firewall DHCP client for use by the hosts served by the DHCP server.

dhcpd auto_config [client_ifx_name]

Syntax Description

auto_config

Enable PIX Firewall to automatically configure DNS, WINS and domain name values from the DHCP client to the DHCP server.

client_ifx_name

This optional argument supports only the outside interface at this time. When more interfaces are supported, this argument will specify which interface supports the DHCP auto_config feature.


Usage Guidelines

DHCP must be enabled to use this command. Use the dhcpd enable command to turn on DHCP.

The DHCP address pool is increased to 256 for all the PIX Firewall version 6.0(1) supported platforms. PIX 506 remains at 32.

Examples

dhcpd auto_config [client_ifx_name]

Related Commands

ip address

failover replicate http

The failover replicate http command allows the stateful replication of HTTP sessions in a Stateful Failover environment. The no form of this command disables HTTP replication in a Stateful Failover configuration. When HTTP replication is enabled, the show failover command displays the failover replicate http command.

[no] failover replicate http
show failover

Usage Guidelines

Enabling Stateful Failover of HTTP sessions has a significant impact on PIX Firewall system resources due to the large number of short-lived HTTP sessions. This command should be used with caution.

Examples

router (config)# show failover

fixup protocol

The fixup protocol command now supports the Skinny Client Control Protocol (SCCP), and support for the Session Initiation Protocol (SIP) has been enhanced.

fixup protocol [protocol skinny [port[-port]]
no fixup protocol [protocol] [port]

show fixup [protocol protocol]
show timeout sip

Syntax Description

fixup protocol

Performs enabling, disabling, viewing, or changing the configuration of a service or protocol through the PIX Firewall.

no

Disables the fixup of a protocol by removing all fixups of the protocol from the configuration using the no fixup command.  After removing all fixups for a protocol, the no fixup form of the command or the default port is stored in the configuration.

port

The port over which the designated protocol travels.

protocol

Specifies the protocol to fix up.

sip

Enables SIP.

show conn state

Displays the connection state of the designated protocol.

show fixup

The show fixup command lists all values or the show fixup protocol protocol command lists an individual protocol.

show timeout

Displays the timeout value of the designated protocol.

skinny

Enables SCCP. SCCP protocol supports IP telephony and can coexist in an H.323 environment. An application layer ensures that all SCCP signaling and media packets can traverse the PIX Firewall and interoperate with H.323 terminals.


Defaults

The default for fixup protocol sip is 5060.

The default for fixup protocol skinny is 2000.

Usage Guidelines

SCCP (skinny) protocol supports IP telephony and can coexist in an H.323 environment. An application layer ensures that all SCCP signaling and media packets can traverse the PIX Firewall and interoperate with H.323 terminals.

To support SIP calls through the PIX Firewall, signaling messages for the media connection addresses, media ports, and embryonic connections for the media must be inspected, because while the signaling is sent over a well known destination port (UDP/TCP 5060), the media streams are dynamically allocated. Therefore, SIP is a text-based protocol and contains the IP addresses throughout the text. The packets are inspected and NAT is provided for the IP addresses.


Note If Call Manager (CM) is configured for NAT and outside phones register to it via TFTP, the connection will fail because PIX Firewall currently does not NAT the configuration file transferred via TFTP.


For additional information about the SIP protocol see RFC 2543. For additional information about the Session Description Protocol (SDP) see RFC 2327.

Examples

fixup protocol [protocol skinny [port[-port]]

fragment

The fragment command provides additional management of packet fragmentation and improves compatibility with NFS.

fragment size database-limit [interface]
fragment chain chain-limit [interface]
fragment timeout seconds [interface]
clear fragment
show fragment
[interface]

Syntax Description

size

Sets the maximum number of packets in the fragment database.

chain

Specifies the maximum number of packets into which a full IP packet can be fragmented.

timeout

Specifies the maximum number of seconds that a packet fragment will wait to be reassembled after the first fragment is received before being discarded.

clear

Resets the fragment databases and defaults. All fragments currently waiting for reassembly are discarded and the size, chain, and timeout options are reset to their default values.

show

Displays the state of the fragment database:

Size - Maximum packets set by the size option.

Chain - Maximum fragments for a single packet set by the chain option.

Timeout - Maximum seconds set by the timeout option.

Queue - Number of packets currently awaiting reassembly.

Assemble - Number of packets successfully reassembled.

Fail - Number of packets which failed to be reassembled.

Overflow - Number of packets which overflowed the fragment database.

database-limit

The default is 200. The maximum is 1,000,000 or the total number of blocks.

chain-limit

The default is 24. The maximum is 8,200.

seconds

The default is 5 seconds. The maximum is 30 seconds.

interface

The PIX Firewall interface. If not specified, the command will apply to all interfaces.


Usage Guidelines

In general, the default values should be used. However, if a large percentage of the network traffic through the PIX Firewall is NFS, additional tuning may be necessary to avoid database overflow. See system log message 209003 for additional information.

In an environment where the MTU between the NFS server and client is small, such as a WAN interface, the chain option may require additional tuning. In this case, NFS over TCP is highly recommended to improve efficiency.

Setting the database-limit of the size option to a large value can make the PIX Firewall more vulnerable to a DoS attack by fragment flooding. Do not set the database-limit equal to or greater than the total number of blocks. The default values will limit DoS due to fragment flooding to that interface only.

Examples

fragment size database-limit [interface]

http

New http commands let you enable the PIX Firewall HTTP server and specify the clients that are allowed to access it.

http ip_address [netmask] [if_name]
no http ip_address netmask if_name

[no] http server enable

clear http
show http


Note The HTTP server must be enabled to configure and monitor the PIX Firewall through PDM.


Syntax Description

http

Relating to the Hypertext Transfer Protocol.

ip_address

Specifies the host or network authorized to initiate an HTTP connection to the PIX Firewall.

netmask

Specifies the network mask for the http ip_address.

if_name

PIX Firewall interface name on which the host or network initiating the HTTP connection resides.

http server enable

Enables the HTTP server required to run PDM.

clear http

Removes all HTTP hosts and disables the server.

show http

Lists the allowed hosts and the enable state of the HTTP server.


Defaults

If you do not specify a netmask, the default is 255.255.255.255 regardless of the class of IP address. The default if_name is inside.

Usage Guidelines

Access from any host will be allowed if 0.0.0.0 0.0.0.0 (or 0 0) is specified for ip_address and netmask.

Examples

The following http command example is used for one host:

http 16.152.1.11 255.255.255.255 outside

The following http command example is used for any host:

http 0.0.0.0 0.0.0.0 inside

ip address

The ip address command has been enhanced to let you enter the number of times the PIX Firewall will poll for DHCP information.

ip address outside dhcp [setroute] [retry retry_cnt]

Syntax Description

dhcp

Specifies PIX Firewall will use DHCP to poll for information.

outside

Interface from which the PIX Firewall will poll for information.

setroute

Tells the PIX Firewall to set the default route using the default gateway parameter the DHCP server returns.

retry

Enables PIX Firewall to retry a poll for DHCP information.

retry_cnt

Specifies the number of times PIX Firewall will poll for DHCP information. The values available are 4 to 16. If no value is specified, the default is 4.


By default the PIX Firewall will not retry to poll for DHCP information. The default value for retry_cnt is 4.

Examples

ip address outside dhcp retry 10

Related Commands

isakmp policy

The isakmp policy command lets you negotiate IPSec security associations and enable IPSec secure communications.

isakmp policy [priority] group 2

Syntax Description

priority

Uniquely identifies the Internet Key Exchange (IKE) policy and assigns a priority to the policy. Use an integer from 1 to 65,534, with 1 being the highest priority and 65,534 the lowest.

group 2

Specifies that the 1024-bit Diffie-Hellman group 2 be used in the IKE policy.


Usage Guidelines

Cisco VPN Client version 3.x uses Diffie-Hellman group 2 and VPN Client version 2.5 uses Diffie-Hellman group 1. If you are using Cisco VPN Client version 3.x, configure Diffie-Hellman group 2 by using the isakmp policy command.

To configure Diffie-Hellman group identifier two, use the isakmp command as noted in the "Command Reference" section of the Cisco PIX Firewall IPSec User Guide, Version 6.0.


Note The Cisco VPN Client version 3.x does not require the crypto map map-name client configuration address initiate | respond command.


Examples

isakmp policy 93 group 2 n

pdm

A new family of commands support PDM communication with a PIX Firewall over an HTTP server. The pdm disconnect command lets you disconnect a specific PDM session using a session_id obtained with the show pdm sessions command. The show pdm sessions command lists all the open PDM sessions going to a PIX Firewall.


Note The pdm disconnect command, and the show pdm sessions command are accessible through the command line. The clear pdm, pdm history commands, pdm location, and pdm logging commands may appear in your configuration and are available through the CLI, but they are designed to work as internal PDM-to-PIX Firewall commands accessible through PDM.


clear pdm

pdm disconnect session_id
show pdm sessions

[no] pdm history enable
show pdm history
[view {all|12h|5d|60m|10m}][snapshot] [feature {all|blocks|cpu|failover|ids|interface if_name|memory|perfmon|xlates}][pdmclient]

pdm location ip_address netmask if_name

pdm logging [level [messages]]
no pdm logging
show pdm logging

Syntax Description

pdm

Pertaining to the Cisco PIX Device Manager.

clear pdm

Removes all locations, disables logging, and clears the PDM buffer. Internal PDM command.

pdm disconnect

Disconnects the specified PDM session from the PIX Firewall.

session_id

PDM session ID number available from the show pdm sessions command.

show pdm sessions

Displays a session_id for each active PDM session to the PIX Firewall, beginning with session number 0.

history enable

Internal PDM command. Take a data sample and store the sample data to the PDM history buffer. The no version of this command disables PDM data sampling.

show pdm history

Internal PDM command. Displays the contents of the PDM history buffer.

12h | 5d | 60m | 10m | all

Specifies the PDM history view to display: 12 hours (12h), 5 days (5d), 60 minutes (60m),10 minutes (10m), or all history contents in the PDM history buffer.

snapshot

Displays only the last PDM history data point.

pdmclient

Displays the PDM history in PDM-display format.

location

Internal PDM command. Associates an interface with an IP address.

ip_address

Specifies the host or network.

netmask

Specifies the network mask for the pdm location ip_address.

if_name

Specifies the interface name for the pdm location ip_address.

logging

Internal PDM command. Specifies the type and number of syslog messages displayed through the PDM syslog option.

level

Specifies the priority level of syslog messages displayed in the PDM syslog option.

messages

Specifies the number of messages stored in the PDM buffer. Once the buffer is full, old messages will be discarded.

show pdm logging

Internal PDM command. Displays the contents of the PDM buffer within PDM.


Defaults

Default PDM syslog level is 0. Default logging messages is 100 and the maximum is 512.

Usage Guidelines

The pdm location command can only associate one interface to an ip_address /netmask pair. Specifying an existing pair will replace the old definition. The PDM syslog messages are stored separately from the PIX Firewall syslog accessed through the logging buffered command.

Examples

This example shows how to report the last data point in PDM-display format:

The reload command has been enhanced with the new option noconfirm. It permits the PIX Firewall without user confirmation.

reload noconfirm

Syntax Description

reload

Reboot and reload configuration.

noconfirm

Permits the PIX Firewall to reload without user confirmation.


Usage Guidelines

The PIX Firewall does not accept abbreviations to the keyword noconfirm.

Command History

The noconfirm option was added to the reload command for PIX Firewall version 6.0(1).

Examples

reload noconfirm

service

This command has been enhanced with the resetoutside option. The resetoutside option allows the PIX Firewall to quickly terminate the identity request (IDENT) from an external SMTP or FTP server. Actively resetting these connections avoids the 32 second time-out delay. This option is recommended with dynamic or static interface PAT (available with version 6.0(1)).

service {resetinbound | resetoutside}

Examples

service {resetinbound | resetoutside}

setup

The setup command lets you provide pre-configuration information to a new PIX Firewall, so you can then configure and monitor your PIX Firewall graphically using PDM.

The host name you want to display in the PIX Firewall command line prompt.

Domain name:

The DNS domain name of the network on which the PIX Firewall runs, for example cisco.com.

IP address of host 
running PIX Device 
Manager:

IP address on which PDM connects to the PIX Firewall.

Use this configuration 
and write to flash?

Store the new configuration to Flash memory. Same as the write memory command. If the answer is yes, the inside interface will be enabled and the requested configuration will be written to Flash memory. If the user answers anything else, the setup dialog repeats using the values already entered as the defaults for the questions.


Usage Guidelines

A PIX Firewall requires some initial configuration before PDM can connect to it. The setup dialog appears, via the console, at boot time if there is no configuration in the Flash memory. You can also access the setup command by typing setup from the config mode.

The dialog asks for the inside IP address, network mask, host name, domain name and PDM host. The host and domain names are used to generate the default certificate for the SSL connection. The interface type is determined from the hardware.

show cpu usage

The show cpu usage command displays CPU utilization. This command is now permitted from privileged or configuration mode.

show cpu usage

Examples

The following example shows the new output:

CPU utilization for 5 seconds: p1%; 1 minute: p2%; 5 minutes: p3%

A more generic form of the output is:

CPU utilization for 5 seconds: p1%; 1 minute: p2%; 5 minutes: p3%

where:

p1 is the percentage utilization for 5 seconds.

p2 is the average percentage utilization for 1 minute.

p3 is the average percentage utilization for 5 minutes.

The percentage usage will be printed as NA (not available) if the usage is not available for any of the time intervals. This can happen if the user asks for CPU usage before the 5-second, 1-minute, or 5-minute time interval has elapsed.

show interface

The show interface command displays network interface information. The show interface command has been enhanced to include buffer counters. The buffer counters are only valid for Ethernet interfaces.

show interface

Usage Guidelines

Use the show interface command to view information about the interface. The show interface command displays the packet drop count of Unicast RPF for each interface. This value appears as the "unicast rpf drops" counter.

Examples

The following example shows the new output:

pix# show interface
interface ethernet0 "outside" is up, line protocol is up
 Hardware is i82559 ethernet, address is 00aa.0000.003b
 IP address 209.165.201.7, subnet mask 255.255.255.224

        4 input errors, 0 CRC, 4 frame, 0 overrun, 0 ignored, 0 abort
        1310091 packets output, 547097270 bytes, 0 underruns, 0 unicast rpf drops
        0 output errors, 28075 collisions, 0 interface resets

        0 lost carrier, 0 no carrier
        input queue (curr/max blocks): hardware (128/128) software (0/1)
        output queue (curr/max blocks): hardware (0/2) software (0/1)
...

The counters in the last two lines are as follows:

Input queue—the input (receive) hardware and software queue.

Hardware—(current and maximum blocks). The number of blocks currently present on the input hardware queue, and the maximum number of blocks previously present on that queue. In the example, there are currently 128 blocks on the input hardware queue, and the maximum number of blocks ever present on this queue was 128.

Software—(current and maximum blocks). The number of blocks currently present on the input software queue, and the maximum number of blocks previously present on that queue. In the example, there are currently 0 blocks on the input software queue, and the maximum number of blocks ever present on this queue was 1.

Output queue—the output (transmit) hardware and software queue.

Hardware—(current and maximum blocks). The number of blocks currently present on the output hardware queue, and the maximum number of blocks previously present on that queue. In the example, there are currently 0 blocks on the output hardware queue, and the maximum number of blocks ever present on this queue was 2.

Software—(current and maximum blocks). The number of blocks currently present on the output software queue, and the maximum number of blocks previously present on that queue. In the example, there are currently 0 blocks on the output software queue, and the maximum number of blocks ever present on this queue was 1.

For Fast Ethernet and Gigabit Ethernet interfaces, the current and maximum count for the number of blocks on the input (receive) queue will always be the same. Currently the count is 128 for Fast Ethernet and 63 for Gigabit Ethernet. The number of blocks on the receive queue is always fixed.

show vpdn

The show vpdn command has been enhanced to display L2TP tunnel and session information.

show vpdn tunnel [l2tp | pptp] [id tunnel_id | packets | state | summary | transport]

show vpdn session [l2tp | pptp] [id session_id | packets | state | window]

The l2tp and pptp command options display either the L2TP or PPTP tunnel information. The PIX Firewall shows both tunnel protocols if this option is not specified.

Syntax Description

show vpdn tunnel

Display tunnel information.

show vpdn session

Display session information.

l2tp | pptp

Select either l2tp or pptp to display that tunnel information. The PIX Firewall shows both tunnel protocols if this option is not specified.

shun

The shun command allows a dynamic response to an attacking host by preventing new connections and disallowing packets from any existing connection. The shun command is intended for use primarily by a Cisco Secure IDS device.

[no] shun src_ip [dst_ip sport dport [protocol]]
clear shun [statistics]
show shun src_ip

Syntax Description

shun

Enable a blocking function (shun) based on src_ip.

no

Disable a shun based on src_ip, the actual address used by the PIX Firewall for shun lookups.

clear

Disable all shuns currently enabled and clears shun statistics. Specifying statistics only clears the counters for that interface.

show

Display all shuns currently enabled in the exact format specified.

src_ip

The address of the attacking host.

dst_ip

The address of the of the target host.

sport

The source port of the connection causing the shun.

dport

The destination port of the connection causing the shun.

protocol

The optional IP protocol, such as UDP or TCP.

statistics

Clear only interface counters.


Defaults

If the shun command is used only with the source IP address of the host, then the other defaults will be 0. No further traffic from the offending host will be allowed.

Usage Guidelines

The shun command applies a blocking function to the interface receiving the attack. Packets containing the IP source address of the attacking host will be dropped and logged until the blocking function is removed manually or by the Cisco Secure IDS master unit. No traffic from the IP source address will be allowed to traverse the PIX Firewall unit and any remaining connections will time out as part of the normal architecture. The blocking function of the shun command is applied whether or not a connection with the specified host address is currently active.

Examples

In the following example, the offending host (10.1.1.27) makes a connection with the victim (10.2.2.89) with TCP. The connection in the PIX Firewall connection table reads as follows:

10.1.1.27, 555-> 10.2.2.89, 666 PROT TCP

if the shun command is applied in the following way:

shun 10.1.1.27 10.2.2.89 555 666 tcp 

The preceding command would delete the connection from the PIX Firewall connection table, and it would also prevent packets from 10.1.1.27 from going through the PIX Firewall. The offending host can be inside or outside of the PIX Firewall.

PIX Firewall version 6.0(1) supports up to 32 SNMP management stations. The snmp-server host command has been modified to facilitate finer granularity in configuring trap and poll activities. There are two enhanced snmp-server host command options.

snmp-server host [if_name] ip_addr [trap | poll]

Syntax Description

snmp-server host

Specify an IP address of the SNMP management station to which traps should be sent and/or from which the SNMP requests come. You can specify up to 32 SNMP management stations.

if_name

The interface name where the SNMP management station resides.

ip_addr

The IP address of a host to which SNMP traps should be sent and/or from which the SNMP requests come.

trap | poll

Specify whether traps, polls, or both are acted upon. Use with these parameters:

trapOnly traps will be sent. This host will not be allowed to poll.

poll—Traps will not be sent. This host will be allowed to poll.

The default allows both traps and polls to be acted upon.


Defaults

If you do not specify either option, the snmp-server host command behaves as in previous versions. The polling is permitted from all configured hosts on the affected interface. Traps are sent to all configured hosts on the affected interface.

Usage Guidelines

Use the trap and poll command options to configure hosts to participate only in specific SNMP activities. Poll responses and traps are sent only to the configured entities. Hosts configured with the trap command option will have traps sent to them, but will not be allowed to poll. Hosts configured with the poll command option will be allowed to poll, but will not have traps sent to them.

Accessibility to the PIX Firewall MIBs is based on configuration, MIB support, and authentication based on the community string. Unsuccessful polling attempts, except for failed community string authentication, are not logged or otherwise indicated. Community authentication failures result in a trap where applicable.

Examples

snmp-server host perimeter 10.1.2.42 trap poll

static

This command has been modified to allow TCP and UDP port redirection.

static [(internal_if_name, external_if_name)] {tcp | udp} {global_ip | interface} global-port local_ip local-port [netmask mask] [max_conns [emb_limit [norandomseq]]]

Syntax Description

internal_if_name

The internal network interface name. The higher security level interface you are accessing.

external_if_name

The external network interface name. The lower security level interface you are accessing.

tcp

Specifies TCP port redirection.

udp

Specifies UDP port redirection.

global-ip

The global IP address used for redirection.

interface

The outside interface address is taken to be the global address.

global-port

Global TCP or UDP port for port redirection.

local-port

Local TCP or UDP port for port redirection.

global_ip

A global IP address. The IP address on the lower security level interface you are accessing.

local_ip

The local IP address from the inside network. The IP address on the higher security level interface you are accessing.

netmask

Reserve word required before specifying the network mask.

mask

Mask pertains to both global_ip and local_ip. For host addresses, always use 255.255.255.255. For network addresses, use the appropriate class mask or subnet mask; for example, for Class A networks, use 255.0.0.0. An example subnet mask is 255.255.255.224.

max_conns

The maximum number of connections permitted through the static at the same time.

em_limit

The embryonic connection limit. An embryonic connection is one that has started but not yet completed. Set this limit to prevent attack by a flood of embryonic connections. The default is 0, which means unlimited connections.

norandomseq

Do not randomize the TCP/IP packet's sequence number. Only use this option if another inline firewall is also randomizing sequence numbers and the result is scrambling the data. Use of this option opens a security hole in the PIX Firewall.


Usage Guidelines

If the tcp or udp keyword is specified, a static UDP or TCP port redirection is configured. If the interface keyword is specified, the outside-interface address is taken to be the global IP address.


Note A conduit or access-list command statement must be configured in addition to the static command to enable an inbound connection.


Examples

This example redirects Telnet traffic from the PIX Firewall unit's outside interface to inside host 10.1.1.15:

static (inside,outside) tcp interface telnet 10.1.1.15 telnet

This example redirects FTP traffic to the PIX Firewall outside interface to inside host 10.1.1.30:

static (inside,outside) tcp interface ftp 10.1.1.15 ftp

This example redirects DNS traffic to the PIX Firewall outside interface to inside host 10.1.1.30:

static (inside,outside) udp interface domain 10.1.1.30 domain

This example redirects all traffic to the PIX Firewall outside interface to inside host 10.1.1.15:

static (inside, outside) interface 10.1.1.15

sysopt connection permit

This sysopt connection permit-12tp command allows L2TP traffic to bypass conduit or access-list command statement checking. The sysopt connection permit-ipsec command implicitly permits all L2TP or IPSec traffic.

sysopt connection permit-l2tp
sysopt connection permit-ipsec

Syntax Description

permit-l2tp

Allows L2TP traffic to bypass conduit or access-list command statement checking.

permit-ipsec

Allows IPSec traffic to bypass conduit or access-list command statement checking.


Usage Guidelines

There is no need to enter the sysopt connection permit-12tp command if the sysopt connection permit-ipsec command is present.

Examples

sysopt connection permit-12tp

vpdn group

New functionality has been added to implement the Point-to-Point Tunneling Protocol (PPTP) and Layer 2 Tunnelling Protocol (L2TP) feature within virtual private dial-up network (VPDN) groups.

vpdn group group_name accept dialin [pptp | l2tp]
vpdn group group_name l2tp tunnel hello [hello_timeout]
vpdn group group_name client accounting [aaa_server_tag]

Syntax Description

Identify the virtual private dial-up network group.

group_name

An ASCII string identifying a VPDN group. Maximum group_name length is 128 bytes.

accept dialin

Accept PPTP or L2TP dial-in request.

pptp | l2tp

Select PPTP or L2TP protocol.

l2tp tunnel hello

Specify the L2TP keep-alive hello timeout value. The default is 60 seconds if not specified. The minimum is 10 seconds and maximum is 300 seconds.

hello_timeout

Tunnel hello keep-alive message timeout period (in seconds).

client accounting

Generate AAA accounting start and stop record for the L2TP (and PPTP) session.

aaa_server_tag

The aaa_server_tag defined from the aaa-server command. The AAA server does not need to be the same server as the AAA authentication server.


Usage Guidelines

The accounting record consists of the following fields:

user-name
Login username.

caller-id

Client's IP address.

acct-flag

Start or stop.

elapsed_time

The duration of the session.

bytes_in/bytes_out

Input and output byte count.

task_id

A unique ID to identify a task.

Nas-P-addr

Address of PIX Firewall.


Examples

The following examples show different configurations of the vpdn group command:

vpdn group 1 accept dialin 12tp
vpdn group 1 12tp tunnel hello 60
vpdn group 1 client accounting myaaa

Important Notes

The following section describes important notes for the 6.0(1) release.

AAA Authentication

Configure the access list specified in Attribute 11 (specifies per-user access-list name) on the PIX Firewall. Otherwise, remove Attribute 11 from the AAA RADIUS server configuration if no access list is intended for user authentication. If the access list is not configured on the PIX Firewall when the user attempts to log in, the login will fail. AAA, RADIUS, and Attribute 11 information can be found at the following websites:

http://www.cisco.com/univercd/cc/td/doc/product/access/acs_soft/csacs4nt/csnt30/user/ad.htm

http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_61/config/mngacl.htm

Downloading PIX Firewall image

Fast Ethernet cards in 64-bit slots are not visible in monitor mode. This problem means that the TFTP server cannot reside on one of these interfaces. The user should use the copy tftp flash command to download the PIX Firewall image file via TFTP.

DHCP Server Functionality

The functionality of the DHCP server on the PIX Firewall has been changed to lets users define a pool of up to 256 DHCP addresses on the PIX 515 and larger platforms. The PIX 506 remains at 32 addresses.

Restrictions

Version 6.0(1) does not support FDDI, PL2, or Token Ring interfaces.

Version 6.0(1) no longer supports PFM; PFM has been replaced by the PIX Device Manager (PDM).

Resolved Caveats - Release 6.0(3)

The caveats in Table 5 are resolved in this release.

Table 5 Resolved Caveats 

DDTS Number
Description
CSCds10112

The system reloads after experiencing continuous denied enroll attempts.

CSCds29190

The PIX Firewall fails over silently when generating an RSA key the size of 2048.

CSCds54310

The PIX crypto map can become corrupted when multiple show crypto commands are issued while the VPN client is running.

CSCds60366

The PIX Firewall reloads after being unable to establish a tunnel.

CSCds80108

Cisco Secure Intrusion Detection System (Cisco Secure IDS) signature number 1101 is not supported by PIX Firewall. When attempted to be accessed, PIX Firewall returns an incorrect error message: Invalid signature number.

CSCds83357

If the certificates and keys are changed, under some circumstances, the PIX Firewall reloads if it is then unable to establish a tunnel.

CSCds89340

If the user enables "debug skinny," the messages accumulate to a certain size and triggers the Watchdog Timeout.

Workaround: Do not enable the "debug skinny".

CSCdt09454

The primary unit's large configuration did not synchronize to the secondary unit.

CSCdt21999

The graphing tables do not load in realtime with Internet Explorer and PDM history metrics disabled on the PIX Firewall.

Workaround: Enable PDM history metrics on your PIX Firewall. This is the default setting.

CSCdt51419

The logging settings on the PIX Firewall are not shown in the configuration when it is configured for no logging on. The logging settings (such as logging monitor debug, etc.) are shown under show logging but not show configuration.

When logging is on, then the logging settings show up.

CSCdt58542

Configure the access-list specified in Attribute 11 (specifies per-user access-list name) on the PIX Firewall. Otherwise, remove Attribute 11 from the AAA RADIUS server configuration if no access-list is intended for user authentication. If the access-list is not configured on the PIX Firewall when the user attempts to log in, the login will fail.

CSCdt63922

Fast Ethernet cards in 64-bit slots are not visible in monitor mode. This problem means that the TFTP server cannot reside on one of these interfaces. The user should use the copy tftp flash command to download the PIX Firewall image file via TFTP.

CSCdt77025

Sporadically, under automated IPSec stress testing, the system indicates that an internal memory packet block has become corrupted.

CSCdt78562

When a refresh is requested, a message dialog is sent: "PDM is unable to get the current version information about your PIX. Your PIX may be unreachable for this moment." This can give the appearance that the PDM is hanging. The solution would be to open this window as a Frame and not as a dialog message. If this window is a Frame, it will be seen on the task bar and will be easier for the user to locate it.

Workaround: The only way to get to the message is to use the alt-tab to the PDM window.

CSCdt79999

When initially bringing up a graph in Internet Explorer, it occasionally picks up one or two extra data points. The table is correct though.

CSCdt81787

Refresh time for PDM is 3 minutes with Sun Sparc Ultra-2/Solaris 2.8/296 MHz/512 MB/Netscape 4.76 and 10 seconds with Windows NT 4.0/500 MHz/128 MB/Internet Explorer 5.50 for 100 KB configuration.

CSCdt83330

The command buffer does not clear after discarding.

CSCdt83450

Many of the realtime graphs are showing the same information as in the 10m graph. They should show the information from the time they are opened.

CSCdt87109

The system slows down and the screen may not refresh properly. The Java console reports a ComFailException error as PDM loads (Low System Resources). This problem typically occurs with Internet Explorer on Windows ME 9. It may happen on other platforms as well and also in Netscape.

If you run PDM and close the PDM window without closing the browser, and then launch PDM again, each time you do this, it consumes more resources, approximately 10% more each time. Eventually, you will run out of resources and the system starts behaving erratically.

CSCdt90421

Memory is not released after clearing all IPSec and ISA SAS connections.

CSCdt92714

In the Hosts/Networks tab on PDM, a network object is edited but no changes are applied. PDM always asks to apply the changes and it does not verify if there are changes or not.

CSCdt93673

Call forwarding from the SIP Proxy server does not work in a single or double PIX Firewall scenario when the call is forwarded to a SIP gateway.

CSCdt94747

Interoperability occurs when using the command fixup protocol H3231720 between a Skinny phone (on the outside) and a Gateway (with a POTs phone) on the inside of a network.

CSCdu00850

NICs (network interface cards) that use the 82542 controller chip are not recommended for installation in the PIX 525. It will result in degraded performance.

CSCdu01836

PIX Device Manager sessions are not released after closing all of the browsers.

CSCdu03550

At startup time, PDM seems frozen if you are using Solaris 2.8, CDE 1.4, Netscape 4.7x environments, but continues to load when you move the mouse.

CSCdu08222

PDM does not accept an `any any' destination address when `static' is not defined when adding a Rule.

CSCdu09113

In the multiple-line command window, it is not clear how to paste a CLI into this window. Right-clicking does not work. The only way to paste CLIs into the command window is to use Ctrl-v.

CSCdu10483

PIX Firewall version 6.0.1 does not delete the ISA SAS if the peer does not negotiate SA.

CSCdu10680

When you copy and paste multiple CLI commands in the CLI window, not all of the commands are configured on the PIX Firewall and there are no errors reported. This problem occurs when you configure the hostname or password in PDM using the CLI window in the multiple line command mode.

CSCdu10826

When configuring the TFTP server on the outside interface by using PDM, the configuration file name defaults to a TFTP directory name. We just need a file name not a directory/file name.

CSCdu12321

The PIX Firewall fails to perform the write memory command when a long command line precedes it.

CSCdu12552

On some Linux machines running only Netscape, when you select an item on the System Properties tab or the Monitoring tab, the entire PDM window shifts up a few pixels to the left and up. Eventually, the title bar of the PDM window may move out of view. On some window managers, you may have to right-click on the edge of the window to get a menu so that you can move the PDM window back into view. On other window managers, pressing the middle mouse button on the edge of the window and dragging it will move the window.

CSCdu12628

The user may have to wait without any hour-glass signal from the PDM after configuring the DHCP Client to run on the PIX Firewall outside interface through the PDM.

CSCdu12990

The graphs for the 2560 byte blocks for both "Blocks Used" and "Blocks Free" always show up as 0.

CSCdu13592

The history view time is incorrect if the connection is lost or the clock is changed.

CSCdu13760

Performance monitoring values increase when you use the show perfmon command.

CSCdu16015

Clicking the Help button a second time causes the help screen to stall.

CSCdu19903

The PDM graphs no longer plot new points when the connection from the PIX Firewall is lost.

Workaround: Close the PDM window and restart.

CSCdu20593

When the Cisco Secure VPN Client version 1.1 is using the mode configuration address, on rekey, the user is prompted for the username and password. On entering the username and password, if you type the show uauth command on the PIX Firewall, one can see two entries for the same client with the same username, one with the mode configuration address and one with the internal address.

CSCdu22069

An xlate entry appears for an outside Proxy's IP address. The call from the inside SIP Phone to the outside SIP Phone through the OUT Proxy is successful but bytes or responses to bytes from the outside phone do not go through.

CSCdu22771

PIX Firewall is sending initial contact during rekeying from PIX Firewall to PIX Firewall. Initial contact should be sent only during the first isakmp negotiation.

CSCdu23013

After adding a policy, it is impossible to cancel or discard changes.

CSCdu23112

PIX Firewall sends invalid data to Entrust CA while getting root certificate.

CSCdu23894

First enrollment request to Baltimore CA fails.

CSCdu24181

If a packet used in setting up an L2TP tunnel arrives late, then the PIX Firewall may reload.

CSCdu25228

Modifying the interface after a change is made to the security level always brings up the security level dialog.

CSCdu25691

L2TP does not respond to a ping for packets larger than 1373 bytes.

CSCdv39306

Opening a TAC Case

The online TAC Case Open Tool (http://www.cisco.com/tac/caseopen) is the fastest way to open P3 and P4 cases. (Your network is minimally impaired or you require product information). After you describe your situation, the TAC Case Open Tool automatically recommends resources for an immediate solution. If your issue is not resolved using these recommendations, your case will be assigned to a Cisco TAC engineer.

For P1 or P2 cases (your production network is down or severely degraded) or if you do not have Internet access, contact Cisco TAC by telephone. Cisco TAC engineers are assigned immediately to P1 and P2 cases to help keep your business operations running smoothly.

To open a case by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447

TAC Case Priority Definitions

To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.

Priority 1 (P1)—Your network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Priority 3 (P3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
