Installation Notes
This section contains important information regarding installation and upgrades to SDM.
Cisco 1700 Routers Running ITS/CCME and Cisco IOS Release 12.2(13)T
If you are installing SDM on a router that already has the Internet Telephony Service (ITS) or Cisco Call Manager Express (CCME) application installed in flash memory, you may exceed the number of files allowed in flash memory by installing SDM. Cisco 1700 routers using a Cisco IOS Release 12.2(13)T image cannot have more than 32 files in flash memory.
Before installing SDM, you must delete any unneeded files from flash memory. If no files can be deleted, do not install SDM on the router.
Downloading SDM from Cisco.com and Installing It on the Router
If SDM is not currently installed on the router, the document Downloading and Installing Cisco Router and Security Device Manager (SDM) explains how to download SDM from Cisco.com and install it on the router. To obtain this document, go to the following URL:
Upgrading to a New SDM Release
If a version of SDM later than version 1.0 is already installed on the router, you should use the SDM automatic update feature to install the latest files on the router. SDM automatically checks Cisco.com for more recent versions of SDM, downloads them to your PC, removes the old 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 > Update from CCO.
If you are currently using SDM version 1.0, you must download the file SDM-Vnn.zip at the following URL:
http://www.cisco.com/pcgi-bin/tablebuild.pl/sdm
The document Downloading and Installing Cisco Router and Security Device Manager (SDM) explains how to install SDM and all related files on the router. This document is available at the following URL:
Uninstalling SDM Files
If you want to remove 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.
SDM version 2.1 or later can be installed on your PC. To remove SDM from your PC, complete the following steps:
Step 1
Step 2
Step 3
Restrictions and Limitations
This section describes restrictions and limitations that may apply to SDM.
SDM Minimum Screen Resolution
SDM requires a screen resolution of at least 1024 x 768.
Restrictions for Cisco 7204VXR, 7206VXR, and 7301 Routers
The following restrictions apply to SDM running on Cisco 7204VXR, 7206VXR, and 7301 Routers:
•

Important Notes
This section contains important information for SDM.
Popup Blockers Disable SDM IPS and SDM Online Help
If you have enabled popup blockers in the browser you use to run SDM or SDM IPS, SDM IPS will not launch, and 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 SDM or SDMIPS. 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
SDM will not start when run under Internet Explorer using JRE plug-in versions 1.4.2_05 and proxy settings are 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 SDM Do Not Execute the Standard Cisco IOS Startup Sequence
Because a default configuration file is provided on a router shipped with 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 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 SDM. Please refer to the router quick start guide and to the SDM FAQ (available at http://www.cisco.com/go/sdm) for information about the minimum configuration required for using 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 SDM to change an existing configuration, refer to the instructions on starting 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 SDM. If this becomes necessary, 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 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 SDM.
Step 1
Step 2
Step 3
Step 4
Step 5
copy flash: filename tftp://tftp-server-address/filename
For example:
Router# copy flash: sdm.tar tftp://10.10.10.3/sdm.tarTable 2 lists the files SDM uses.

Example:
Router# copy tftp://10.10.10.3/SDM.tar flash:
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 SDM Launches
When 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 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 2.1.1
This section lists caveats that are open in release 2.1.1.
•
VPN status in the Monitor windows do not show IPSec security association (SA) parameters for DMVPN whenCLI status commands report that the crypto tunnels are up and traffic is passing through. The DMVPN tunnel is shown as established in the IKE SA tab.
Workaround: Use the CLI to view DMVPN status.
•
This problem is encountered on routers running Cisco IOS image c3825-advsecurityk9-mz.123-10.2. If an ATM interface is configured on routers running this image, WAN troubleshooting may display inconsistent results. PVC connections may be shown as UP when they are DOWN.
Workaround: None.
•
When both SDM and IPS are open, an open dialog box requiring an OK or Cancel in one application will prevent the user from working in the other application.
Workaround: Complete the work in the dialog box and click OK, or click Cancel to close the dialog box before switching to the other application.
•
If multiple instances of SDM are run under Netscape version 7.1 using the Java Virtual Machine (JVM) or the Java plug-in, and the user shuts down one instance of SDM, then all other open instances of SDM on that PC are shut down.
This problem occurs because Netscape version 7.1 uses only one instance of the JVM or the Java plug-in, even when multiple instances of Netscape are launched. As a result, when one instance of SDM is shut down, Netscape shuts down the JVM or the Java plug-in, and all other instances of SDM are also shut down.
Workaround: If SDM is run under Netscape version 7.1, open only one instance of SDM . Using Internet Explorer is advised when multiple instances of SDM must be opened, such as when the user must configure multiple routers at the same time.
•
When the crypto identity ca command is used, the Loopback0 interface is shown as having no configured IP address in the Edit Interfaces and Connections window when an IP address has been configured.
Workaround: Disregard the IP address information in the Interfaces and Connections window. If you need to view the IP address, choose the interface and click the Edit button.
•
This problem is caused by the Cisco IOS caveat CSCef46305. After an Easy VPN Remote connection has been brought up after a successful user authentication (Xauth), the remote peer may not be listed in the Easy VPN Remote Edit screen if SDM is refreshed or reinvoked. If this problem occurs, Easy VPN Remote troubleshooting might not behave as expected for this connection.
This problem will occur only when the Easy VPN server sends Xauth challenges to the Easy VPN remote at the same time that the Easy VPN remote is trying to establish a tunnel with the VPN server.
Workaround: None.
•
When an Easy VPN Server is configured using Digital Certificates for authentication, and an Easy VPN Remote connection is configured on another router, the client statistics for the Easy VPN server are all shown as 0 in the VPN Status window.
Workaround: To view client statistics, choose Tools > Telnet. Log in to the router, and issue the show crypto session command.
•
When adding a new signature to the ATOMIC.ICMP engine, you may see the error message "[Enum(xxx)-StorageKey-ATOMIC.ICMP] the value AaBb is not a valid value."
Workaround: In the Add Signature window, go to the parameter StorageKey, and click the green square to enable editing for this parameter. the green square icon will change to a red diamond icon. Choosing any value from the drop down box will fix this problem.
•
This problem is caused by the Cisco IOS caveat CSCef64124. When the user unchecks the Save Xauth username and password on the router check box in the Edit Easy VPN Remote dialog box and clicks OK, the command is delivered to the router, but SDM shows the check box as checked, and the corresponding command is still shown in the running configuration if SDM is refreshed.
This occurs when the user wants to remove the saved Xauth username and password in Easy VPN Remote.
•
If an Easy VPN Remote configuration has connections to more than one Easy VPN server configured, VPN troubleshooting decaveatging may report troubleshooting results for only one VPN server or give incorrect recommendations. This issue is seen only in some Cisco IOS images.
Workaround: None.
•
Invoking SDM with a user associated with SDM_Monitor view adds a PKI trust point and an Easy VPN profile. This behavior does not affect the running configuration.
Workaround: Invoke SDM with a user associated with a different CLI view, or with a user of privilege level 15.
•
SDM filenames are case sensitive. If the SDM files are copied from the PC hard disk to a flash card, File Explorer changes the names to uppercase. When this happens, SDM cannot be invoked from this flash card.
Workaround: Before removing the flash card from the PC, restore the filenames to lowercase.
•
When the router is running a Cisco IOS image that does not support the show pppoe session command, WAN troubleshooting may not report any reasons for failure or recommended actions for PPPoE connections that are found to be down.
Workaround: None.
•
If a firewall is configured for an interface which already has a Management Access policy associated with it, choosing Replace in the Merge/Replace dialog box might prevent access to certain networks.
This occurs because choosing Replace causes the policy access control entries (ACEs) to be disassociated from the interface but not from the vty or HTTP line.
Workaround: When running Firewall wizard on an interface configured with Management Access policy, choose Merge option instead of Replace and proceed.
•
VPN troubleshooting may report a possible Maximum Transmission Unit (MTU) problem in the passthrough network when the tunnel is up. If the VPN interface is a dialer interface configured on an asynchronous interface, this problem may not always exist, and the displayed recommended action will have no effect.
Workaround: Ignore this message and the corresponding recommendation.
•
Due to a problem with Cisco IOS, if a custom protocol is mapped to a port and the same custom protocol is specified for matching under a classmap, and then the mapping of the custom protocol is deleted from the configuration , Cisco IOS does not give any warning message that the user should first delete the match protocol custom-01 commands that make use of the custom protocol mapping.
Workaround: Do the following:
–
–
–
•
This problem is caused by Cisco IOS caveat CSCef52919. A user with privilege level 1 who is associated with a view may be able to log in to SDM with a privilege level of 15. This occurs when authentication authorization and accounting (AAA) is enabled, and a vty line is configured with privilege level 2 through 15.
Workaround: Do not configure privilege 1-level users. The problem does not occur when users of higher privilege levels are configured.
•
When you update SDM, if any of the uploaded SDM files shows a size of zero bytes when show flash is invoked, no operations such as copy or delete can be performed on flash memory. This problem rarely occurs.
Workaround: Restart the router to be able to perform operations on flash memory. If files of zero bytes are shown in a show flash display, restart the router before starting SDM.
•
Router does not reload with default configuration when a' user executes a Reset To Factory Defaults operation in SDM.
If the router is running Cisco IOS Release 12.2(11)T6, and the last 4 bits of the config-register value are set to 0, for example 0x2100 or 0x1100, the router does not reload when the user performs a Reset To Factory Defaults. SDM indicates that it has sent a reload command to the router and shuts down, and the default configuration is copied to the startup-config, but the reload command has not executed, and the router is still using the running configuration that was present before the Reset To Factory Defaults operation.
Workaround: Use the CLI config-register command to ensure that the last 4 bits of the config register are not set to 0 (zero).
•
If you delete a WAN connection that you created, an ip nat inside command may still remain in a LAN interface configuration.
Workaround: To delete the ip nat inside command from the LAN interface configuration, go t o Edit Interfaces and Connections, choose the LAN interface, click Edit, and delete the association in the Association tab.
•
Enabling AES encryption or IP compression in the Add/Edit IKE Policy or Add/Edit Transform Set windows might not work even though the Cisco IOS image running on the router supports AES encryption or IP Compression. This may happen in the following circumstances:
–
–
Workaround: Do one of the following:
–
–
For more info on VPN Modules, refer to the document at the following URL:
http://www.cisco.com/en/US/products/hw/routers/ps259/products_data_sheet09186a0080088750.html
•
When configuring static routing, if a virtual-template interface is configured as the next hop interface in a static route, SDM generates corresponding CLI commands. Delivering such commands to the router may fail on some platforms.
Workaround: Do not configure a virtual-template interface as a next hop interface if it is not supported on the router.
•
When SDM runs with a Cisco IOS image of a release earlier than 12.3T, or earlier than Release 12.2(13)ZH, the HTTP server appends unnecessary characters to names of files it displays. As a result, when SDM is started, the web browser displays the warning "Content does not match the signature."
Workaround: Disregard the warning and click Yes to continue.
•
When an Easy VPN tunnel is active, using SDM to apply a NAT configuration to the Easy VPN inside and outside interfaces will deliver ip nat inside and ip nat outside commands to the router, but the running configuration will not be changed. SDM displays no error message when this is attempted.
Workaround: To apply a NAT configuration to interfaces that have been designated as Easy VPN inside or outside interfaces, complete the following steps in SDM:
–
–
–
•
SDM will not start on a Cisco 831 router with 32 MB of memory if run from Netscape. An exception will be displayed in the Java console window, and in the router console window indicating a memory allocation failure.
Workaround: Run SDM using Internet Explorer version 5.5 or later. Or, if you want to continue to use Netscape, log in to the router CLI and enter the following memory-size command in global configuration mode:
Router# memory-size iomem 10•
XAuth authentication intermittently fails, and Easy VPN tunnels cannot be established using SDM on routers running Cisco IOS Release 12.3(4)T. When the user attempts to do an Xauth authentication in SDM, the following error message is displayed:
Unable to establish a session with the router to process XAUTH request from the Easy VPN server. Easy VPN tunnel cannot be successfully brought up.This message is followed by another indicating that the connect command was delivered to the router, but that the tunnel was not established.
Workaround: In the VPN Connections window, choose the Easy VPN tunnel configuration and click the Reset Tunnel button to clear the tunnel and reconnect it. If this does not bring up the tunnel, use the Login button, more than once if necessary, to bring up the tunnel.
•
When SDM Express runs with Cisco IOS image of Release 12.2(15)T, it fails to download the configuration file from the CNS server through the SDM Express wizard. See CSCin65539 for more details. This issue occurs only with Cisco IOS Release 12.2(15)T.
Workaround: Upgrade to Cisco IOS Release 12.3(4)T or later.
•
On Cisco 7x00 routers, the SDM Update feature is supported if the current SDM files were loaded onto the router flash disk or CompactFlash disk. However, the SDM Updates feature fails to upload new SDM files to the router if the current SDM files were installed in flash memory. The SDM Updates feature uses RCP protocol to upload the new SDM files to the router, but the RCP Server misinterprets the "flag" sent by the RCP Client for the above mentioned file systems.
Workaround: If the current SDM files were loaded into flash memory, update to the new SDM version by manually copying the new SDM files to the file system of the router using a TFTP server. To make use of the automatic SDM Update feature, always install SDM files on the flash disk or CompactFlash disks (disk0, disk1, disk2).
•
SDM should not get invoked from boot images such as kboot images on 72xx routers. Such boot images are a subset of the Cisco IOS software and do not support all router functions.
Workaround: Boot the router with an SDM-supported Cisco IOS image, and then invoke SDM. See Table 1 for the Cisco IOS releases that SDM supports.
•
On 72xx platforms, encryption is not supported on PA-4T port adapters. Because the CLI does not support crypto maps for these types of interfaces, SDM will fail to assign crypto maps to these interfaces. The PA-4T port adapter will not support future compression and encryption features.
Workaround: Upgrade your 72xx router hardware to the 4t+ PA port adapter.
•
Whenever any unconfigured interface contains the description $FW_INSIDE$, on a router configured with a firewall, adding a new NTP server will not modify the firewall ACLs to allow NTP passthrough traffic. Instead, when the user edits the firewall's outside interface in the Interfaces and Connections window, SDM prompts the user to add the NTP passthrough traffic.
Workaround: Use the CLI to manually remove the description $FW_INSIDE$ from the unconfigured interface.
•
If the interface used for the primary backup connection is configured for PPPoE encapsulation, the backup connection will not function properly if the next hop address is specified during configuration. A Cisco IOS caveat (CSCin64336) has been filed for this problem. If the interface used for the primary backup connection is an Ethernet interface configured without encapsulation, the backup connection will not function properly if the next hop address is not specified during configuration.
Workaround: Do one of the following:
–
–
•
If the WAN wizard is used to configure an analog modem connection as a primary backup connection, and the analog modem connection is deleted, SDM may report that the interface contains unsupported configuration parameters.
Workaround: Click Refresh on the SDM toolbar, and delete the connection.
•
The Interfaces and Connections window may display the Backup option in disabled state for asynchronous interfaces on Cisco 831 and Cisco 837 routers. This will occur when the following operations have been performed:
–
–
–
When the IP address of the primary interface is changed, SDM displays a Yes or No warning popup asking if you want to remove the backup configuration. If you choose Yes, SDM removes the backup configuration, but the Interfaces and Connections window still shows the backup option as disabled, preventing you from choosing the asynchronous interface as a backup interface.
Workaround: Delete the asynchronous interface configuration using the Interfaces and Connections window.
•
When the router is configured to use PPPoE, users may not be able to download a file using FTP or display web pages from Internet hosts that they are able to ping or access using telnet. This can happen if SDM is being used on a router with interfaces that SDM does not support, such as Token Ring or VLAN interfaces. SDM does not deliver the command ip tcp adjust-mss 1452 to unsupported interfaces.
Workaround: Use the CLI to add the ip tcp adjust-mss 1452 command to the VLAN or Token Ring interface configuration. Use Telnet to access the router and enter the following command in VLAN or Token Ring interface configuration mode:
Router# ip tcp adjust-mss 1452•
The SDM Express wizard may not deliver the configuration to a Cisco 2691 router running Cisco IOS images of Release 12.2(15)T or 12.2(15)ZJ when SSH is used to communicate between SDM Express and the router. When SDM Express is invoked using the string https://router-IP-address, it uses SSH.
Workaround: When launching SDM Express, click Cancel in the SSH credentials window. SDM Express will use the Telnet protocol to communicate with the router. Enter the login ID and password in the Telnet credentials window.
•
When launching the Dynamic Multipoint Virtual Private Network (DMVPN) Hub and Spoke wizard, SDM may take up to 12 seconds to display the first wizard window. This latency may occur if a JRE plug-in of any version is running in the browser, or if SDM is using the SSH or Telnet communications module.
•
SDM may take several seconds to display screens in the DMVPN wizard. This latency may occur if a Java plug-in is running in the browser.
•
Using anIP unnumbered interface as a DMVPN tunnel source may cause Cisco IOS to crash. An interface configured as IP unnumbered uses the IP address of another interface on the router. This Cisco IOS problem does not always occur.
Workaround: Instead of using an IP unnumbered interface as the DMVPN tunnel source, use the interface that is referenced in the ip unnumbered command. If you are configuring a hub, the interface must have a static IP address.
•
The router reloads when an NHRP tunnel interface is removed. This is a Cisco IOS caveat which you may encounter when deleting a DMVPN tunnel. This caveat duplicates CSCed41641.
Workaround: There is no workaround for this problem.
•
If an Analog Modem or ISDN connection is deleted using SDM, the dialer interface may not be deleted from the configuration and the router may reload. This is due to a Cisco IOS caveat, CSCin69090. This occurs on routers using Cisco IOS images of Release 12.3(4)XG or later, or Cisco IOS Release 12.3(7)T.
Workaround: There is no workaround for this problem.
•
On routers running Cisco IOS Release 12.3(6), Cisco IOS may reload if SDM is started using HTTPS.
Workaround: Start SDM by entering http://ip-address. Do not use https://ip-address.
•
The SDM Express wizard may fail if the router is running Cisco IOS Release 12.3(9) and there is not sufficient space in NVRAM to save the startup configuration. This problem should not occur with new routers.
Workaround: If this problem occurs, use the CLI to remove unneeded files from NVRAM.
•
SDM does not issue the ntp update-calendar Cisco IOS command on Cisco 7200 routers if there are no new settings to enter and if the Network Time Protocol (NTP) server was configured using the CLI, only one NTP server IP address was provided and no ntp update-calendar Cisco IOS command was present in the running configuration.
Workaround: Use SDM to delete the NTP server configuration entry, click Refresh, and then re-create the entry, or make changes to the existing NTP server entry.
•
Because of a Cisco IOS issue (CSCee63313), if SDM is used to enable IPS on an interface, and then used to disable IPS on that interface, the router crashes.
•
Due to a Cisco IOS issue (refer to CSCee58000), SDM is unable to configure a virtual auxiliary port on Cisco 831, 836, or 837 routers running Cisco IOS Release 12.3(7)XR1.
