Introduction

Cisco PDM Version 4.1 is a web-based application used to configure and monitor the Firewall Services Module (FWSM) on a Catalyst 6500 series switch or Cisco 7600 series router. PDM Version 4.1 requires FWSM Release 2.3 or 2.2 and supports all of the configuration features in this release. For more information, see FWSM Technical Documentation and the FWSM FAQ (Frequently Asked Questions) sections on Cisco.com..


Note PDM Version 4.1 is a single image that supports FWSM Release 2.3 and 2.2. It does not support FWSM Release 1.1 or the PIX operating system.


PDM Software Overview

PDM Version 4.1 is a single image that provides secure administration of the FWSM. PDM is implemented as a signed Java applet, which downloads to your PC or workstation when you point your browser at the FWSM and does not require a plug-in or other software to be preinstalled. PDM manages FWSM Release 2.3 and 2.2 when it runs in single or multiple context modes.

PDM provides a graphical user interface to the FWSM to administer it without requiring knowledge of the command-line interface (CLI). PDM also maintains compatibility with the FWSM CLI and includes a tool for using the standard CLI commands within the PDM application. PDM allows you to graph many aspects of the FWSM, as well as print or export graphs of the traffic through the FWSM and of system activity.

To help you use PDM, the application provides online help as well as a help table of contents, index, and glossary.

Switch and Router System Requirements

The following switch and router models that are supported by the FWSM are:

Catalyst 6500 series switches with the following required components:

Supervisor engine with Cisco IOS software or Catalyst operating system

Multilayer Switch Feature Card (MSFC 2) with Cisco IOS software

Cisco 7600 series routers, with the following required components:

Supervisor engine with Cisco IOS software

MSFC 2 with Cisco IOS software

For more information about supported supervisor engine and software versions and the supported Cisco IOS software, refer to the Catalyst 6500 Series Switch and Cisco 7600 Series Router Firewall Services Module Configuration Guide Version 2.3.


Note The FWSM does not support a direct connection to a switch WAN port because WAN ports do not use static virtual local area networks (VLANs). However, the WAN port can connect to the MSFC, which can also connect to the FWSM.


For more information on switch or router requirements for FWSM, go to the following website: http://www.cisco.com/en/US/products/hw/modules/ps2706/ps4452/tsd_products_support_model_home.html

The following sections list the system requirements for PDM Version 4.1 software.

FWSM Requirements

The FWSM must meet the following requirements to successfully install and run PDM:

Minimum Software Versions-Verify that your FWSM meets the requirements listed in the Release Notes for the Catalyst 6500 Series Switch and Cisco 7600 Series Router Firewall Services Module Software Release. You must have Release 2.3 or 2.2 installed on the FWSM before using PDM Version 4.1. For more information, refer to the Cisco PDM Installation and Configuration Guide for Firewall Services Module.

Upgrading Software-When you install a new version of PDM, close all browser sessions before launching PDM. For information on upgrading your FWSM, see the following websites:

http://www.cisco.com/cisco/software/navigator.html?a=ahttp://www.cisco.com/public/sw-center/index.shtmli=rpm

http://www.cisco.com/en/US/products/hw/modules/ps2706/ps4452/tsd_products_support_model_home.html


Caution If you are using Management Center for Firewalls, use PDM for monitoring only. All changes made using PDM will be overwritten the next time Management Center for Firewalls synchronizes with the FWSM.

Browser Requirements

The following are required to access one or more firewalls through PDM:

Java Virtual Machine (JVM)-PDM 4.1 supports native JVM on Microsoft Internet Explorer 6.0, Java Plug-in 1.4.2 or Java Plug-in 5.0. PDM 4.1 supports native JVM on Solaris Red Hat or Linux with Java Plug-in 1.4.2.

HTTP 1.1-For Microsoft Internet Explorer, be sure to use HTTP 1.1 for both proxy and non-proxy connections. This can be changed in Tools > Internet Options > Advanced tab. Scroll down to the "HTTP 1.1 settings" section.

Maximum Configuration File Size

For optimum performance, we recommend a configuration file of no more than 500 KB when using PDM.

FWSM Firewall configuration files over 500 KB may interfere with the performance of PDM on your workstation in the following situations:

While executing commands such as write term and show run

Failover (the configuration synchronization time)

During a PDM Refresh Operation or loading PDM for the first time

PC and Workstation Requirements

PDM has different requirements depending on the platform from which it is accessed. PDM is not supported for use on computers equipped with the Macintosh operating system, or other versions of the Windows operating systems.

Supported Platforms

Table 1 lists the supported and recommended platforms for PDM Version 4.1.


Note The Japanese version of Windows (JOS) is supported in the PDM Version 4.1 release.

New and Changed Information

The following sections provide new and changed information for this release.

HTTPS Authentication Proxy

This feature provides a secure mechanism for exchanging username and password information between an HTTP client and FWSM using HTTPS.

ACL Per User Override

This feature allows an external server to override the configuration of the access rules policy for that interface. This feature only applies to inbound ACLs.

Resource Manager for ACL Memory Pool

This feature allows you to manage resources for ACLs, including the ACL memory pool or ACL tree instances, which are used when compiling ACLs.

Resource Class for PDM Sessions

This feature allows you to specify the number of PDM sessions for a particular context.

Suspend/Resume Failover Configuration Sync

This feature provides the ability to disable failover synchronization from an active device to a standby device.

Same Security Intra Interface

This feature allows a packet to come in and go out on the same interface. A router might forward a packet to the FWSM so that it can apply the user's firewall policy on that packet.

TFTP Fixup

This feature inspects the TFTP protocol and dynamically creates a connection and xlate if necessary to permit file transfer between a TFTP client and server. This feature was included in FWSM 2.2.

Syslog Enhancements

These enhancements allow you to specify the amount of memory that can be allocated for the syslog messages per context and to optionally deny connections if the syslog queue is full.

Important Notes

This section describes important notes for PDM software Version 4.1.

One-time Password

PDM does not support the one-time password (OTP) authentication mechanism.

Fixups

Both fixup SIP over TCP and fixup SIP over UDP are supported in FWSM Release 1.1, but fixup SIP over UDP cannot be disabled in FWSM Release 1.1. Fixup SIP over UDP can only be disabled in FWSM Release 2.x.

CLI Command Support

This section indicates which CLIs PDM supports.

Fully Supported CLI Commands

PDM parses these commands when uploading or creating the FWSM configuration and gives you full access to all PDM user-interface tabs.

Table 2 lists the CLI commands that PDM fully supports. PDM parses these commands in the FWSM configuration and allows PDM to operate successfully.

Exceptions are noted in the table and occur when PDM cannot parse certain combinations of command statements. Commands that PDM cannot parse stay in the configuration, their values cannot be changed with PDM, and they appear in the list of unparseable commands.

Miscellaneous CLI Command Operation Limitations

Table 5 lists miscellaneous CLI command limitations in PDM 4.1.

Table 5 Miscellaneous CLI Command Limitations 

FWSM Commands
Result

access-list

Ignored if the access-list is not used anywhere in the configuration.

prefix-list

Ignored if it is not used in an OSPF area (CLI: area <area-id> filter-list prefix)

Discontinuous net masks such as 255.255.0.255. Example CLI: ip address inside 192.168.2.1 255.255.0.255

n/a

Use of aaa ... include and aaa ... match

Limited to monitor-only

No access to write, show pdm, show version, and show curpriv

PDM will not run.

Sharing of ACLs. Example CLI: access-group myACL in interface inside and access-group myACL in interface outside

PDM will display this as expected. However if you make a modification to an ACL that is being shared, PDM will prompt you to duplicate this ACL so that the ACL is no longer shared.


PDM does not support the one-time password (OTP) authentication mechanism.

CLI Commands Ignored by PDM in FWSM

These CLI commands are displayed in the list of unparseable commands in PDM. However, PDM does not change or remove these commands from your configuration, and the presence of these commands does not limit your access to the user-interface tabs in PDM. To see ignored commands, select Options > Show Commands Ignored by PDM on Firewall.

PDM Sessions

The FWSM can be configured to support up to five PDM sessions in single mode or five PDM sessions per context in multiple mode up to a total of 32 PDM sessions.
