ROMMON and TFTP
ROMMON uses TFTP to download an image and launch it. TFTP does not address network issues such as latency or error recovery. It does implement a limited packet integrity check so that packets arriving in sequence with the correct integrity value have an extremely low probability of error. But TFTP does not offer pipelining so the total transfer time is equal to the number of packets to be transferred times the network average RTT. Because of this limitation, we recommend that the TFTP server be located on the same LAN segment as the sensor. Any network with an RTT less than a 100 milliseconds should provide reliable delivery of the image. Be aware that some TFTP servers limit the maximum file size that can be transferred to ~32 MB.
IPS Management and Event Viewers
Use the following tools for configuring Cisco IPS 7.1(4)E4 sensors:
•Cisco IDM 7.1.4
IDM 7.1.4 is included within the IPS 7.1(4)E4 files.
IDM 7.1.4 is included within IME 7.2.1.

•Cisco IME 7.2.1
You can use IME 7.2.1 to configure IPS 6.1, 6.2, 7.0, and 7.1 sensors.
•IPS CLI included in IPS 7.1(4)E4.
•Cisco ASDM 6.3.4 and later.
Use the following tools for monitoring Cisco IPS 7.1(4)E4 sensors:
•IDM 7.1.4
•IME 7.2.1
•MARS minimum version 5.2 and latest version 6.0.5
MARS does not support the IPS 4500 series sensors.
•Cisco Security Manager 4.0 and later
Cisco Security Manager 4.0(2) does not support the IPS 4270-20.
Cisco Security Manager 4.3 and later supports the IPS 4500 series sensors.
Note You may need to configure viewers that are already configured to monitor the earlier version sensors to accept a new SSL certificate for the Cisco IPS 7.1 sensors.
New and Changed Information
Cisco IPS 7.1(4)E4 contains the following new and changed information:
•Support for the IPS 4510 and IPS 4520.
•Although IME 7.2.1 supports the new platforms (IPS 4510 and IPS 4520), the online help does not yet reference them.
•Contains signature update S648.
•Continuing support for the IPS 4270-20, IPS 4340, IPS 4360, ASA 5585-X IPS SSP series, and ASA 5500-X IPS SSP series.
AC Power Supply in the IPS 4300 Series V01 and V02 Chassis
The Cisco IPS 4300 series sensors with the AC power supply can restore the previous power state of the system if AC power is lost. Earlier IPS 4300s (V01) require you to turn on the power with the power switch. Newer IPS 4300s (V02) automatically turn on when you plug in the power cable.
To determine your version, do one of the following:
•At the CLI, enter the show inventory command and look for V01 or V02 in the output.
•On the back of the chassis, look at the VID PID label for V01 or V02.
The V01 chassis has the following limitations (these limitations do not apply to the V02 chassis):
•The sensor requires 50 seconds from the time that AC power is applied before the power state can be updated and stored. This means that any changes to the power state within the first 50 seconds of applying AC power will not be observed if AC power is removed within that time.
•The sensor requires 10 seconds from the time it is placed into standby mode before the power state can be updated and stored. This means any changes to the power state within the first 10 seconds of entering standby mode (including the standby mode itself) will not be observed if AC power is removed within that time.
For More Information
For information on the AC power supplies in the IPS 4300 series sensors, refer to Installing the IPS 4345 and IPS 4360.
The IDM and JRE 1.7
In IPS versions 7.1(1)E4 through 7.1(5)E4, the IDM fails to connect to the sensor due to a failure during the initial handshake, because the web server is not RFC 5746-compliant. Try the following workaround.
Problem Cannot launch the IDM, when the IDM is running under JRE 1.7 with IPS 7.1(1)E4 through 7.1(5)E4.
Solution Use JRE 1.6 or enable the SSL 2.0-compatible ClientHello format in the Java settings under Control Panel.
The Sensor and Jumbo Packet Frame Size
For IPS standalone appliances with 1 G and 10 G fixed or add-on interfaces, the maximum jumbo frame size is 9216 bytes. For integrated IPS sensors, such as the ASA 5500-X and ASA 5585-X series, refer to the following URL for information:
http://www.cisco.com/en/US/docs/security/asa/asa84/configuration/guide/interface_start.html#wp1328869
Note A jumbo frame is an Ethernet packet that is larger than the standard maximum of 1518 bytes (including Layer 2 header and FCS).
The ASA IPS Modules and Jumbo Packets
The jumbo packet count in the show interface command output from the lines Total Jumbo Packets Received and Total Jumbo Packets Transmitted for ASA IPS modules may be larger than expected due to some packets that were almost jumbo size on the wire being counted as jumbo size by the IPS. This miscount is a result of header bytes added to the packet by the ASA before the packet is transmitted to the IPS. For IPv4, 58 bytes of header data are added. For IPv6, 78 bytes of header data are added. The ASA removes the added IPS header before the packet leaves the ASA.

Note The controller type errors are a known issue and can be disregarded.
Step 3 Press Break or Esc at the following prompt while the system is booting to interrupt boot. Press the spacebar to begin boot immediately.
Note You have ten seconds to press Break or Esc.
Use BREAK or ESC to interrupt boot.
Use SPACE to begin boot immediately.
The system enters ROMMON mode. The rommon> prompt appears.
Step 4 Check the current network settings.
ROMMON Variable Settings:
The variables have the following definitions:
•Address—Specifies the local IP address of the IPS 4270-20.
•Server—Specifies the TFTP server IP address where the application image is stored.
•Gateway—Specifies the gateway IP address used by the IPS 4270-20.
•Port—Specifies the Ethernet interface used for IPS 4270-20 management.
•VLAN—Specifies the VLAN ID number (leave as untagged).
•Image—Specifies the system image file/path name.
•Config—Unused by these platforms.
Note Not all values are required to establish network connectivity. The address, server, gateway, and image values are required. If you are not sure of the settings needed for your local environment, contact your system administrator.
Step 5 If necessary, assign an IP address for the local port on the IPS 4270-20.
rommon> ADDRESS=ip_address
Note Use the same IP address that is assigned to the IPS 4270-20.
Step 6 If necessary, assign the TFTP server IP address.
rommon> SERVER=ip_address
Step 7 If necessary, assign the gateway IP address.
rommon> GATEWAY=ip_address
Step 8 Verify that you have access to the TFTP server by pinging it from your local Ethernet port with one of the following commands:
rommon> ping server_ip_address
Step 9 If necessary define the path and filename on the TFTP file server from which you are downloading the image.
rommon> IMAGE=path/file_name
UNIX Example
rommon> IMAGE=/system_images/IPS-4270_20-K9-sys-1.1-a-7.1-4-E4.img
Note The path is relative to the UNIX TFTP server default tftpboot directory. Images located in the default tftpboot directory do not have any directory names or slashes in the IMAGE specification.
Windows Example
rommon> IMAGE=\system_images\IPS-4270_20-K9-sys-1.1-a-7.1-4-E4.img
Step 10 Enter set and press Enter to verify the network settings.
Note You can use the sync command to store these settings in NVRAM so they are maintained across boots. Otherwise, you must enter this information each time you want to boot an image from ROMMON.
Step 11 Download and install the system image.
Caution
To avoid corrupting the system image, do not remove power from the IPS 4270-20 while the system image is being installed.
Note If the network settings are correct, the system downloads and boots the specified image on the IPS 4270-20. Be sure to use the IPS 4270-20 image.

After you install the sensor on your network, you must use the setup command to initialize it so that you can communicate with it over the network. You cannot use the IDM or the IME to configure the sensor until you initialize the sensor using the setup command.
With the setup command, you configure basic sensor settings, including the hostname, IP interfaces, access control lists, global correlation servers, and time settings. You can continue using advanced setup in the CLI to enable Telnet, configure the web server, and assign and enable virtual sensors and interfaces, or you can use the Startup Wizard in the IDM or the IME. After you configure the sensor with the setup command, you can change the network settings in the IDM or the IME.
Caution
You must have a valid sensor license for global correlation features to function. You can still configure and display statistics for the global correlation features, but the global correlation databases are cleared and no updates are attempted. Once you install a valid license, the global correlation features are reactivated.
Simplified Setup Mode
The sensor automatically calls the setup command when you connect to the sensor using a console cable and the sensor basic network settings have not yet been configured. The sensor does not call automatic setup under the following conditions:
•When initialization has already been successfully completed.
•If you have recovered or downgraded the sensor.
•If you have set the host configuration to default after successfully configuring the sensor using automatic setup.
When you enter the setup command, an interactive dialog called the System Configuration Dialog appears on the system console screen. The System Configuration Dialog guides you through the configuration process. The values shown in brackets next to each prompt are the default values last set.
System Configuration Dialog
When you enter the setup command, an interactive dialog called the System Configuration Dialog appears on the system console screen. The System Configuration Dialog guides you through the configuration process. The values shown in brackets next to each prompt are the current values.
You must go through the entire System Configuration Dialog until you come to the option that you want to change. To accept default settings for items that you do not want to change, press Enter.
To return to the EXEC prompt without making changes and without going through the entire System Configuration Dialog, press Ctrl-C. The System Configuration Dialog also provides help text for each prompt. To access the help text, enter ? at a prompt.
When you complete your changes, the System Configuration Dialog shows you the configuration that you created during the setup session. It also asks you if you want to use this configuration. If you enter yes, the configuration is saved. If you enter no, the configuration is not saved and the process begins again. There is no default for this prompt; you must enter either yes or no.
You can configure daylight savings time either in recurring mode or date mode. If you choose recurring mode, the start and end days are based on week, day, month, and time. If you choose date mode, the start and end days are based on month, day, year, and time. Choosing disable turns off daylight savings time.
Note You only need to set the date and time in the System Configuration Dialog if the system is an appliance and is NOT using NTP.
Note The System Configuration Dialog is an interactive dialog. The default settings are displayed.
Example 1 shows a sample System Configuration Dialog.

Basic Sensor Setup
To perform basic sensor setup using the setup command, follow these steps:
Step 1 Log in to the sensor using an account with administrator privileges.
Note Both the default username and password are cisco.
Step 2 The first time you log in to the sensor you are prompted to change the default password. Passwords must be at least eight characters long and be strong, that is, not be a dictionary word. After you change the password, basic setup begins.
Step 3 Enter the setup command. The System Configuration Dialog is displayed.
Step 4 Specify the hostname. The hostname is a case-sensitive character string up to 64 characters. Numbers, "_" and "-" are valid, but spaces are not acceptable. The default is sensor.
Step 5 Specify the IP interface. The IP interface is in the form of IP Address/Netmask,Gateway: X.X.X.X/nn,Y.Y.Y.Y, where X.X.X.X specifies the sensor IP address as a 32-bit address written as 4 octets separated by periods, nn specifies the number of bits in the netmask, and Y.Y.Y.Y specifies the default gateway as a 32-bit address written as 4 octets separated by periods.
Step 6 Enter yes to modify the network access list:
a. If you want to delete an entry, enter the number of the entry and press Enter, or press Enter to get to the Permit line.
b. Enter the IP address and netmask of the network you want to add to the access list.
Note For example, 10.0.0.0/8 permits all IP addresses on the 10.0.0.0 network (10.0.0.0-10.255.255.255) and 10.1.1.0/24 permits only the IP addresses on the 10.1.1.0 subnet (10.1.1.0-10.1.1.255). If you want to permit access to a single IP address than the entire network, use a 32-bit netmask. For example, 10.1.1.1/32 permits just the 10.1.1.1 address.
c. Repeat Step b until you have added all networks that you want to add to the access list, and then press Enter at a blank permit line to go to the next step.
Step 7 You must configure a DNS server or an HTTP proxy server for global correlation to operate:
a. Enter yes to add a DNS server, and then enter the DNS server IP address.

Step 3 Display the self-signed X.509 certificate (needed by TLS).
sensor# show tls fingerprint
MD5: C4:BC:F2:92:C2:E2:4D:EB:92:0F:E4:86:53:6A:C6:01
SHA1: 64:9B:AC:DE:21:62:0C:D3:57:2E:9B:E5:3D:04:8F:A7:FD:CD:6F:27
Step 4 Write down the certificate fingerprints. You need the fingerprints to check the authenticity of the certificate when connecting to this sensor with a web browser.
Logging In to the IDM
The IDM is a web-based, Java Web Start application that enables you to configure and manage your sensor. The web server for the IDM resides on the sensor. You can access it through Internet Explorer or Firefox web browsers.
Note The IDM is already installed on the sensor.
To log in to the IDM, follow these steps:
Step 1 Open a web browser and enter the sensor IP address. A Security Alert dialog box appears.
https://sensor_ip_address
Note The default IP address is 192.168.1.2/24,192.168.1.1, which you change to reflect your network environment when you initialize the sensor. When you change the web server port, you must specify the port in the URL address of your browser when you connect to the IDM in the format https://sensor_ip_address:port (for example, https://192.0.2.1:1040).
Step 2 Click Yes to accept the security certificate. The Cisco IPS Device Manager Version window appears.
Step 3 To launch the IDM, click Run IDM. The JAVA loading message box appears, and then the Warning - Security dialog box appears.
Step 4 To verify the security certificate, check the Always trust content from this publisher check box, and click Yes. The JAVA Web Start progress dialog box appears, and then the IDM on ip_address dialog box appears.
Step 5 To create a shortcut for the IDM, click Yes. The Cisco IDM Launcher dialog box appears.
Note You must have JRE 1.5 (JAVA 5) installed to create shortcuts for the IDM. If you have JRE 1.6 (JAVA 6) installed, the shortcut is created automatically.
Step 6 To authenticate the IDM, enter your username and password, and click OK. Both the default username and password are cisco. You were prompted to change the password during sensor initialization. The IDM begins to load. If you change panes from Home to Configuration or Monitoring before the IDM has completed initialization, a Status dialog box appears with the following message:
Please wait while IDM is loading the current configuration from the sensor.
The main window of the IDM appears.
Note If you created a shortcut, you can launch the IDM by double-clicking the IDM shortcut icon. You can also close the The Cisco IPS Device Manager Version window. After you launch the IDM, it is not necessary for this window to remain open.
Installing or Upgrading the IME
This section describes how to install and upgrade the IME, and how to migrate data from IEV or a previous version of IME.
Cisco IEV, Cisco IOS IPS, and CSM
If you have a version of Cisco IPS Event Viewer installed, the Install wizard prompts you to remove it before installing the IME.
The IME event monitoring is also supported in IOS-IPS versions that support the Cisco IPS 5.x/6.x signature format. We recommend IOS-IPS 12.4(15)T4 if you intend to use the IME to monitor an IOS IPS device. Some of the new IME functionality including health monitoring is not supported.
Caution
Do not install the IME on top of existing installations of CSM. You must uninstall CSM before installing the IME.
Installation Notes and Caveats
Note If you are using Windows 7 or Windows Server 2008, and an IME version earlier than 7.1.1, uninstall IME before upgrading it. Otherwise, just upgrade from your current IME version.
Observe the following when installing or upgrading the IME:
•You can install the IME over all versions of the IME but not over IEV. All alert database and user settings are preserved.
•The IME detects previous versions of IEV and prompts you to manually remove the older version before installing the IME or to install the IME on another system. The installation program then stops.
•Make sure you close any open instances of the IME before upgrading to a new version of the IME.
•Disable any anti-virus or host-based intrusion detection software before beginning the installation, and close any open applications. The installer spawns a command shell application that may trigger your host-based detection software, which causes the installation to fail.
•You must be administrator to install the IME.
•The IME coexists with other instances of the MySQL database. If you have a MySQL database installed on your system, you do NOT have to uninstall it before installing the IME.
Installing or Upgrading the IME
To install the IME, follow these steps:
Step 1 From the Download Software site on Cisco.com, download the IME executable file to your computer, or start the IDM in a browser window, and under Cisco IPS Manager Express, click download to install the IME executable file. IME-7.2.2.exe is an example of what the IME executable file might look like.
Step 2 Double-click the executable file. The Cisco IPS Manager Express - InstallShield Wizard appears. You receive a warning if you have a previous version of Cisco IPS Event Viewer installed. Acknowledge the warning, and exit installation. Remove the older version of IEV, and then continue the IME installation
Step 3 Click Next to start the IME installation.
Step 4 Accept the license agreement and click Next.
Step 5 Click Next to choose the destination folder, click Install to install the IME, and then click Finish to exit the wizard. The Cisco IME and Cisco IME Demo icons are now on your desktop.
Note The first time you start the IME, you are prompted to set up a password.
Migrating IEV Data
To migrate IEV 5.x events to the IME, you must exit the installation and manually export the old events by using the IEV 5.x export function to move the data to local files. After installing the IME, you can import these files to the new IME system.
Note The IME does not support import and migration functions for IEV 4.x.
To export event data from IEV 5.x to a local file:
Step 1 From IEV 5.x, choose File > Database Administration > Export Database Tables.
Step 2 Enter the file name and select the table(s).
Step 3 Click OK. The events in the selected table(s) are exported to the specified local file.
Importing IEV Event Data In to IME
To import event data in to the IME, follow these steps:
Step 1 From the IME, choose File > Import.
Step 2 Select the file exported from IEV 5.x and click Open. The contents of the selected file are imported in to the IME.
For More Information
For more information about the IME, refer to Cisco Intrusion Prevention System Manager Express Installation Guide for IPS 7.1.

Disabling Anomaly Detection Using the CLI
If you have anomaly detection enabled and you have your sensor configured to see only one direction of traffic, you should disable anomaly detection. Otherwise, you will receive many alerts, because anomaly detection sees asymmetric traffic as having incomplete connections, that is, like worm scanners, and fires alerts.
To disable anomaly detection, follow these steps:
Step 1 Log in to the CLI using an account with administrator privileges.
Step 2 Enter analysis engine submode.
sensor# configure terminal
sensor(config)# service analysis-engine
Step 3 Enter the virtual sensor name that contains the anomaly detection policy you want to disable.
sensor(config-ana)# virtual-sensor vs0
Step 4 Disable anomaly detection operational mode.
sensor(config-ana-vir)# anomaly-detection
sensor(config-ana-vir-ano)# operational-mode inactive
sensor(config-ana-vir-ano)#
Step 5 Exit analysis engine submode.
sensor(config-ana-vir-ano)# exit
sensor(config-ana-vir)# exit
sensor(config-ana-)# exit
Step 6 Press Enter to apply your changes or enter no to discard them.
For More Information

Restrictions and Limitations
The following restrictions and limitations apply to Cisco IPS 7.1(4)E4 software and the products that run it:
•On the IPS 4510 and IPS 4520, no interface-related configurations are allowed when the SensorApp is down.
•When the IPS 4510 and IPS 4520 are configured in VLAN pairs, the packet display command does not work without the VLAN option if the expression keyword is also used.
•The IPS 4510 and IPS 4520 take about 10 to 15 seconds longer to boot up as compared to the IPS 4270-20.
•On the IPS 4270-20, rx/tx flow control is disabled. This is a change from IPS 7.0 where rx/tx flow control is enabled by default.
•The memory usage statistics on the sensor will always show a high value, because the SensorApp reserves the entire memory with the exception of about 2 GB. This makes the memory management more efficient.
• For the ASA 5585-X IPS SSP, IPS 4510, and IPS 4520, when monitored through the IDM or the IME, the CPU usage is always shown as 100% even when no traffic is being inspected. This is due to the SensorApp threads continuously polling the Regex accelerator card queues to get the packets for processing. You can obtain the actual inspection load by using the following command:
sensor# show statistics virtual-sensor | in Load
Processing Load Percentage = 1
•The show interface command output for the IPS 4510 and IPS 4520 does not include the total undersize packets or total transmit FIFO overruns.
•When the IPS 4510 and IPS 4520 are in bypass mode, VLAN statistics in the show interface and packet display/capture command output do not show any packets.
•After you upgrade the IPS software on your sensor, you must restart IDM so that the latest features for the new software version are present in IDM.
•The IPS 4345 and IPS 4360 do not support hardware bypass.
•The ASA 5512-X IPS SSP and the ASA 5515-X IPS SSP do not support the Regex accelerator card and the String XL engines.
•Use the show statistics virtual-sensor | include load command (CLI) or look at the statistics for the virtual sensor at Configuration > Sensor Monitoring > Support Information > Statistics (IDM/IME) to determine the load value over a longer period of time. The show statistics analysis-engine command (CLI) and the statistics for the Analysis Engine show values over a shorter period of time. If you compare the output, the values will appear to be inconsistent due to the different time periods. To get an accurate comparison between them, compare the processing load percentage from the statistics for the virtual sensor and the one-minute averaged value from the statistics for the Analysis Engine.
•TACACS+ authentication is not supported in IPS 7.1(4)E4.
•The CLI timeout feature is applicable only for sessions established through SSH, Telnet, and the console. Service account logins are not affected.
•Anomaly detection does not support IPv6 traffic; only IPv4 traffic is directed to the anomaly detection processor.
•IPv6 does not support the following event actions: Request Block Host, Request Block Connection, or Request Rate Limit.
•Global correlation does not support IPv6.
•There is no support for IPv6 on the management (command and control) interface.
•ICMP signature engines do not support ICMPv6, they are IPv4-specific, for example, the Traffic ICMP signature engine. ICMPv6 is covered by the Atomic IP Advanced signature engine.
•Cisco Security Manager and MARS do not support IPv6.
•When deploying an IPS sensor monitoring two sides of a network device that does TCP sequence number randomization, we recommend using a virtual senor for each side of the device.
•For IPS 5.0 and later, you can no longer remove the cisco account. You can disable it using the no password cisco command, but you cannot remove it. To use the no password cisco command, there must be another administrator account on the sensor. Removing the cisco account through the service account is not supported. If you remove the cisco account through the service account, the sensor most likely will not boot up, so to recover the sensor you must reinstall the sensor system image.
•After you upgrade any IPS software on your sensor, you must restart the IDM to see the latest software features.
•The IDM does not support any non-English characters, such as the German umlaut or any other special language characters. If you enter such characters as a part of an object name through IDM, they are turned into something unrecognizable and you will not be able to delete or edit the resulting object through IDM or the CLI. This is true for any string that is used by the CLI as an identifier, for example, names of time periods, inspect maps, server and URL lists, and interfaces.
•When SensorApp is reconfigured, there is a short period when SensorApp is unable to respond to any queries. Wait a few minutes after reconfiguration is complete before querying SensorApp for additional information.
•The IDM and IME launch MySDN from the last browser window you opened, which is the default setting for Windows. To change this default behavior, in Internet Explorer, choose Tools > Internet Options, and then click the Advanced tab. Scroll down and uncheck the Reuse windows for launching shortcuts check box.
