Release Notes for Cisco Router and Security Device Manager 2.3.4
Revised: December 13, 2006 OL-5009-15Introduction
These release notes support Cisco Router and Security Device Manager version 2.3.4. They should be used with the documents listed in the "Related Documentation" section. These release notes are updated as needed.
Cisco Router and Security Device Manager (Cisco SDM) is a web-based configuration tool that allows you to configure LAN and WAN interfaces, routing, Network Admission Control (NAC), Network Address Translation (NAT), firewalls, Intrusion Prevention System (IPS), Virtual Private Networks (VPNs), and other features on the router. Cisco SDM 2.1 and later versions can be installed on a PC, or in router flash, disk, or slot memory. Earlier versions of Cisco SDM cannot be installed on PCs, and can be installed in router flash, disk, or slot memory. If you have a router listed in the "Hardware Supported" section, Cisco SDM is either preinstalled in router memory, or is shipped on a CD with the router.
Cisco SDM Express allows you to give a router a basic LAN, WAN, firewall and NAT configuration. It is installed in router memory.

Installation Notes
This section contains important information regarding installation and upgrades to Cisco SDM.
Cisco 1700 Routers Running Cisco ITS/Cisco CallManager Express and Cisco IOS Release 12.2(13)T
If you are installing Cisco SDM on a router that already has the Internet Telephony Service (ITS) or Cisco CallManager Express application installed in flash memory, you may exceed the number of files allowed in flash memory by installing Cisco SDM. Cisco 1700 routers using Cisco IOS Release 12.2(13)T cannot have more than 32 files in flash memory.
Before installing Cisco SDM, you must delete any unneeded files from flash memory. If no files can be deleted, do not install Cisco SDM on the router.
Downloading Cisco SDM from Cisco.com and Installing It on the Router
If Cisco SDM is not currently installed on the router, see Downloading and Installing Cisco Router and Security Device Manager (SDM) to learn how to download Cisco SDM from Cisco.com and install it on the router. To obtain this document, go to the following URL:
Upgrading to a New Cisco SDM Version
If a version of Cisco SDM later than version 1.0 is already installed on the router, use the automatic update feature to install the latest files on the router. Cisco SDM automatically checks Cisco.com for more recent versions of Cisco SDM, downloads them to your PC, removes the old Cisco SDM files from memory, runs the squeeze flash: command if necessary, and copies the latest files to the router. The update feature is available from the Tools menu. Choose Tools > Update SDM > From Cisco.com.
If you are currently using Cisco SDM 1.0, you must download the file SDM-Vnn.zip at the following URL:
http://www.cisco.com/cgi-bin/tablebuild.pl/sdm
See Downloading and Installing Cisco Router and Security Device Manager (SDM) to learn how to install Cisco SDM and all related files on the router at the following URL:
Click Install and Upgrade in the Technical Documentation and Tools box, and then click Install and Upgrade Guides.
Uninstalling Cisco SDM Files
If you want to remove Cisco SDM from flash memory or from a router disk file system, you can do so by logging onto the router and completing the following steps in EXEC mode:
Step 1
If the router has a flash file system, use the following command:
router# cd flash:If the router has a disk file system, use the following command:
router# cd diskNReplace N with the actual number of the disk. Use the slot keyword instead of the disk keyword if necessary.
Step 2
router# delete sdm.tarDelete filename [sdm.tar]?Delete flash:sdm.tar? [confirm]Press Return to confirm the deletion.
Step 3
Step 4
router# squeeze flash:It is not necessary to use the squeeze flash: command on DOS-based file systems.

Cisco SDM Does Not Support a Configuration File Larger Than 250 Kilobytes
Cisco SDM does not support router configuration files larger than 250 Kb. If the configuration file on your router is larger than 250 Kb, Cisco SDM stops and displays an error message indicating that the configuration file exceeds the 250 Kb limit.
Cisco SDM Security Dashboard May Display Threats Unrelated to Your Cisco IOS IPS Installation
Some (or all) of the top threats you obtain using the Cisco SDM Security Dashboard may not pertain to your Cisco IOS IPS installation. After you deploy the signatures applicable to the top threats displayed by the Cisco SDM Security Dashboard, the Cisco SDM Security Dashboard may still display some (or all) top threats with a red icon because applicable signatures could not be found. Those remaining top threats are unrelated to your Cisco IOS IPS installation and not a danger to your router running Cisco IOS software.
Cisco SDM May not Launch Using IP Address of WebVPN Gateway
This information provides more information about the caveat CSCek33306. When Cisco SDM attempts to connect to a router with a WebVPN gateway configured using the Cisco IOS CLI, it might not launch from the IP address used by that gateway if the CLI statements necessary for Cisco SDM access are not included.
For example, if you have configured a WebVPN connection on the interface Fe 0/0 with the gateway IP address 10.10.10.1, and thegateway name MyWebVPN, you may not be able to launch Cisco SDM using that IP address.
To be able to launch Cisco SDM using that IP address, add the following Cisco IOS CLI commands:
Router#config tRouter(config)# interface loopback next-available-loopback-numberRouter(config-if)# description Do not delete - SDM WebVPN generated interfaceRouter(config-if)# ip address 192.168.1.1 255.255.255.252Router(config-if)# no shutdownRouter(config-if)# ip nat insideRouter(config-if)# exitRouter(config)# ip nat inside source static tcp 192.168.1.1 443 10.10.10.1 4443Router(config)# router(config)# webvpn gateway MyWebVPNRouter(config-webvpn-gateway)# http-redirect port 80Router(config) # interface FastEthernet 0/0Router(config-if)# ip nat outsideRouter(config-if)# exitAfter adding these commands, you can launch Cisco SDM by entering the following IP address and port in the browser:
https://10.10.10.1:4443If you remove the WebVPN gateway that was modified for Cisco SDM access, you must remove the loopback interface and NAT rule that you created to allow access in the first place. Enter the commands shown in the description of caveat CSCek38259.
Cisco SDM IPS User Guide Discontinued for Cisco SDM 2.2 and Later
The SDM IPS application has been merged with SDM version 2.2. Instructions for using IPS are included in the Cisco Router and Security Device Manager Version 2.2 User's Guide. No SDM IPS User's Guide has been published for this release.
Cisco SDM May Lose Connection to Network Access Device
This note concerns the NAC feature.
If the PC used to invoke Cisco SDM returns a posture state (Healthy, Infected, Checkup, Quarantine, or Unknown) and if the group policy on the ACS server attached to the posture token assigned to the PC has a redirect URL configured, the connection between Cisco SDM and the router acting as the Network Access Device (NAD) may be lost. The same problem can occur if an exception list entry attached to a policy with a redirect URL is configured with the IP address or MAC address of the PC.
If you try to reinvoke Cisco SDM from this PC, you will not be able to do so because the browser will be redirected to the location specified in the redirect URL.
There are two workarounds for this problem:
•
•
For more information, see the links in the Cisco SDM NAC online help pages.
Cisco SDM on PC May Not Launch under Windows XP with Service Pack 2
When Cisco SDM is installed on a PC running Windows XP with Service Pack 2, Internet Explorer may display HTML source code when you attempt to launch Cisco SDM. To fix this problem, go to Tools > Internet Options > Advanced. Then scroll to the Security section, check Allow active content to run in files on my computer, and click Apply. Then relaunch Cisco SDM.
Popup Blockers Disable Cisco SDM Online Help
If you have enabled popup blockers in the browser you use to run Cisco SDM, Cisco SDM online help will not appear when you click the help button. To prevent this from happening, you must disable the popup blocker when you run Cisco SDM. Popup blockers may be enabled in search engine toolbars, or may be standalone applications integrated with the web browser.
Microsoft Windows XP with Service Pack 2 blocks popups by default. In order to turn off popup blocking in Internet Explorer, go to Tools > Pop-up Blocker > Turn Off Pop-up Blocker.
If you have not installed and enabled pop up blockers, go to Tools >Internet Options > Privacy, and uncheck the Block popups checkbox.
Disable Proxy Settings
Cisco SDM will not start when run under Internet Explorer with proxy settings enabled. To correct this problem, choose Internet Options from the Tools menu, click the Connections tab, and then click the LAN settings button. In the LAN Settings window, disable the proxy settings.
Routers Shipped with Cisco SDM Do Not Execute the Standard Cisco IOS Startup Sequence
Because a default configuration file is provided on a router shipped with Cisco SDM, the router will not execute the standard Cisco IOS startup sequence. If you are expecting to use the Cisco IOS setup utility, a TFTP/BOOTP configuration download, or other features available through the standard Cisco IOS startup, you will need to erase the configuration file.
To erase the existing configuration and take advantage of the Cisco IOS startup sequence, perform the following steps. This will leave Cisco SDM on the router if you later decide you want to use it, but you will need to configure the router manually before you can begin using Cisco SDM. Please see the router quick start guide and to the Cisco SDM FAQ (available at http://www.cisco.com/go/sdm) for information about the minimum configuration required for using Cisco SDM.
Step 1
Step 2
Step 3
Step 4
yourname> enablePassword: ciscoyourname#Step 5
yourname# erase startup-configStep 6
Step 7
yourname# reloadStep 8
After the router completes the reload operation, it enters into the standard Cisco IOS startup sequence. You can use the startup sequence to give the router a configuration manually, or to copy a configuration file from the network. If you later decide you want to use Cisco SDM to change an existing configuration, see the instructions on starting Cisco SDM included in the quick start guide for the router.
Unable to Perform "squeeze flash:" Operation
If the router is using a Cisco IOS image earlier than release 12.3T, or release 12.2(13)ZH, it may be necessary to use the squeeze flash: command to reclaim flash memory after repeated use of Cisco SDM. If this becomes necessary, Cisco SDM will inform you that the squeeze flash: command must be used, and will execute the command upon your confirmation.
However, the squeeze flash: command will not work if an erase flash: command has never been executed on the router. If this is the case you will receive an "Unable to perform `squeeze flash'" warning message, and you will need to run the erase flash: command to enable the use of the squeeze flash: command.
Executing the erase flash: command removes Cisco SDM and the Cisco IOS image from the router flash memory, and you will lose your connection to the router. Complete the following steps to save files in flash memory, execute erase flash:, and copy the files back so you can reconnect to Cisco SDM.
Step 1
Step 2
Step 3
Step 4
Step 5

Note
Step 9
Now that an erase flash: operation has been performed on the router, you will be able to execute the squeeze flash: command when necessary.
Security Alert Dialog May Remain After Cisco SDM Launches
When Cisco SDM is launched using HTTPS, a security alert dialog box that informs you of possible security problems and asks you if you want to proceed with program launch may appear. This can happen if the router does not have the following global configuration command in the running configuration:
ip http timeout-policy idle 600 life 86400 requests 10000Caveats
Caveats describe unexpected behavior in Cisco SDM. Severity 1 caveats are the most serious caveats, severity 2 caveats are less serious, and severity 3 caveats are the least serious of these three severity levels.
Open Caveats—Release 2.3.4
This section lists caveats that are open in release 2.3.4
•
If you use the SDM install wizard to install SDM on a router that is running Cisco IOS 12.4(12), or if the file management feature is used to place a .tar file on the router running Cisco IOS 12.4(12), the operation may fail.
Workaround:
The workaround for both problems is to manually copy the files from the PC to the router using TFTP or FTP.
•
If the router is configured to allow Cisco SDM access through a WebVPN gateway that listens on the standard port 443, and that gateway is modified to listen on another custom port, the commands that were added for Cisco SDM access are not automatically removed, and must be removed using the Cisco IOS CLI. The WebVPN gateway may have been configured using the Cisco SDM WebVPN wizard, or it may have been configured manually and then modified to allow Cisco SDM access by adding the commands described in Cisco SDM May not Launch Using IP Address of WebVPN Gateway.
Workaround:
To safely edit the the WebVPN gateway to listen to a port other than 443, do the following:
a.
b.
c.
d.
e.
Cisco SDM can now be invoked using the standard HTTPS port 443.
If you prefer to use the Cisco IOS CLI, enter the following commands to remove the loopback interface and NAT rule that were added to allow Cisco SDM access. In these steps, Loopback 0 with an IP address of 192.168.1.1, and FastEthernet 0/0 with an IP address of 10.20.30.40 are used as examples.
Router# config tRouter(config)# no interface Loopback0Router(config)# interface FastEthernet0/0Router(config-if)# no ip nat outsideRouter(config-if)# exitRouter(config)# no ip nat inside source static tcp 192.168.1.1 443 10.20.30.40 4443Router(config)# exit
