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.

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 information on the AC power supplies in the IPS 4300 series sensors, refer to Installing the IPS 4345 and IPS 4360.

Initializing the Sensor
This section describes how to initialize the sensor using the setup command, and contains the following sections:
- Understanding Initialization
- Simplified Setup Mode
- System Configuration Dialog
- Basic Sensor Setup
- Advanced Setup for the IPS Appliance
- Advanced Setup for the ASA 5500-X IPS SSP
- Advanced Setup for the ASA 5585-X IPS SSP
- Verifying Initialization
Understanding Initialization
Note You must be administrator to use the setup command.
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.
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.
Example 1 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.

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.
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-7.2.5.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.
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 about the IME, refer to Cisco Intrusion Prevention System Manager Express Installation Guide for IPS 7.3.

Restrictions and Limitations
The following restrictions and limitations apply to the Cisco IPS 7.3(5)E4 software and the products that run it:
- IME 7.2.7 is the only supported IME release for IPS 7.3(5)E4.
- After upgrading to 7.3(5)E4, you cannot create a hostname that contains '/'(slash) character.
- Due to a limitation in IPS, you only need to configure the primary DNS IP address and to avoid configuring secondary/tertiary DNS IP addresses. In a scenario where only the primary DNS IP address is configured either with a working or non-working DNS IP address, IPS works smoothly with the working DNS IP address and doesn't work with non-working DNS IP address as expected. If a secondary/tertiary DNS IP address is configured on IPS, then you need to disable the secondary/tertiary DNS IP addresses through the CLI first and then perform /etc/init.d/cids restart on the IPS device to configure Auto Update.
- Reassemble timeout of 10 seconds:
There are 1000 datagram slots, and with the reduced 10 second timeout, 1000/10=100 dgrams/sec can be achieved. Each datagram is at least 2 packets, and hence, with the revised fix for CSCun76930 IPS should handle at least 200pps, assuming all fragments are reassembled.
Workaround: Depending on the your network, you can tune a parameter from the service user prompt to handle up to 1000pps.
File to be modified: sensorApp.conf
- Based on lab testing, We observed that the IPS could comfortably handle upto 400pps.The IDM has been built and tested with JAVA 7 Update 45 and earlier. The IDM is not compatible with JAVA 7 Update 51. For IDM to function, you must use the older version of Java. Refer to CSCum55433 if you must use Java 7u51 and there is no option to use earlier versions.
- While executing the autoupgradenow command, you cannot use the IDM, IME or the CLI or start any new sessions until the upgrade is complete.
- IPS 7.3(5)E4 supports TLS 1.0 and later. If the peer uses an older SSL version, the connection cannot be established. All management applications using the IPS Web server, such as the IDM or CSM, are affected by this change. If the management application does not support TLS1.0 or later, the management connectivity is lost after upgrading to IPS 7.3(5) because it does not support TLS versions earlier than TLS1.0.
- If the client does not support SSHv2 or if SSHv2 is disabled, the management connectivity is lost after upgrading from IPS 7.1( x)E4 to IPS 7.3(5)E4 because SSHv1 is disabled by default in IPS 7.3(5) and later.
- LACP has been tested only on the IPS sensor and the Nexus 7000 switch and the Catalyst 6000 switch. Other combinations of IPS sensors and switches have not been tested. It is unknown if the solution will work as expected with other switches. Also, VPC/VSS configurations are NOT supported.
- Link state mirroring applies to the inline interface pair configuration only. Detecting that the peer interface is up or down and setting the state of the link may take up to 3.5 seconds.
- The IPS 4520 is the only platform that supports the dual configuration. You can add another 4520 module to an existing 4520 or you can order the 4520-XL with two modules already installed. Mixing 4510s and 4520s is not a valid configuration.
- To support the immediate automatic update feature, a default update schedule with a start time of 00:00:00 and interval of 24 hours has been set. You must enable the automatic update settings before issuing an immediate automatic update. Disable the automatic update schedule if you do not want to use the default scheduled update.
- 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.
- Applying any signature template erases any existing tunings associated with the targeted signature definition file. The ASA 5512-X IPS SSP and ASA 5515-X IPS SSP do not support signature templates (signature threat profiles).
- The ASA 5512-X IPS SSP and ASA 5515-X IPS SSP do not support HTTP advanced decoding.
- Enabling HTTP advanced decoding can have a significantly negative performance and memory impact on the sensor.
- 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 7.3(5)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.
- CSM 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 the SensorApp is reconfigured, there is a short period when the SensorApp is unable to respond to any queries. Wait a few minutes after reconfiguration is complete before querying the 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.
