Release Notes for Cisco Intrusion Prevention System 7.1(1)E4
Published: March 31, 2011Revised: October 31, 2012
Note The Cisco ASA 5585-X with the ASA 5585-X IPS SSP is currently the only platform that supports Cisco IPS 7.1(1)E4. No other Cisco IPS sensors currently support this version.
Note The Cisco ASA 5585-X with the ASA 5585-X IPS SSP is supported in ASA 8.2(4.4) and higher as well as ASA 8.4(2) and higher. It is not supported in ASA 8.3(x).
IPS File List
The following files are part of Cisco IPS 7.1(1)E4:
•System Image Files
•Recovery Image Files
Cisco IPS 7.1(1)E4 is supported on the following platforms:
•ASA 5585-X SSP-10 with IPS SSP-10
•ASA 5585-X SSP-20 with IPS SSP-20
•ASA 5585-X SSP-40 with IPS SSP-40
•ASA 5585-X SSP-60 with IPS SSP-60
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
Note IDM version 7.1.1 is included within IME 7.1.1. You can use IME 7.1.1 to configure IPS 6.1, 6.2, 7.0, and 7.1 sensors.

Starting the IDM
Note After you upgrade any IPS software on your sensor, you must restart the IDM to see the latest software features.
There are two ways to start the IDM:
•Cross launch from the IME (recommended)
Open the IME and click Configuration. All the IDM functionality is available in the IME.
•Through a browser
Enter the IP address of the target sensor in the address window as follows:https://xx.xx.xx.xx
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://10.1.9.201:1040).
Step 2 Click Yes to accept the security certificate. The Cisco IPS Device Manager Version 7.1 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. 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 Both the default username and password are cisco. You were prompted to change the password during sensor initialization.
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 7.1 window. After you launch the IDM, it is not necessary for this window to remain open.
Installing or Upgrading Cisco IME
This section describes how to install and upgrade the IME, and contains the following topics:
Before Installing or Upgrading the IME
Caution The IME does not automatically uninstall IEV.
IME 7.1.1 detects previous versions of IEV and prompts you to manually remove the older version before installing IME 7.1 or to install the IME on another system. The installation program then stops. IME 7.1.1 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 IME 7.1.1.
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 IME 7.1.1, you can import these files to the new IME system.
Note IME 7.1.1 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 the 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.
Cisco IME Installation and Upgrade Instructions
Cisco IPS Event Viewer and 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.
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.
IME Installation and Upgrade Caveats
•Make sure you close any open instances of IME 7.0.1 before upgrading to IME 7.1.1.
•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.
•Do not install the IME on top of existing installations of CSM. You must uninstall CSM before installing the IME.
Installing or Upgrading to IME 7.1.1
You can install IME 7.1.1 over IME 7.0.1. All alert database and user settings are preserved.
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_1_1.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.
Step 3 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 IME installation.
Step 4 Double-click the executable file. The Cisco IPS Manager Express - InstallShield Wizard appears.
Step 5 Click Next to start IME installation.
Step 6 Accept the license agreement and click Next.
Step 7 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.

Traffic Flow Stopped with Fail-Open Policy on IPS Switchports
Problem Traffic on any port located on the ASA 5585-X IPS SSP (1/x) no longer passes through the adaptive security when the ASA 5585-X IPS SSP is reset or shut down. This affects all traffic through these ports regardless of whether or not the traffic would have been monitored by the IPS. The link on the ports will link down when the ASA 5585-X IPS SSP is reset or shut down.
Possible Cause Using the ports located on the ASA 5585-X IPS SSP (1/x), and resetting or shutting down the ASA 5585-X IPS SSP via any mechanism.
Solution Use the ports on the adaptive security appliance (0/x) instead because those ports do not lose their link when the ASA 5585-X IPS SSP is reset or shut down.
ASA IPS 5585-X and Jumbo Packet Frame Size
Refer to the following URL for information about the jumbo packet frame size for the ASA modules:
Note A jumbo frame is an Ethernet packet that is larger than the standard maximum of 1518 bytes (including Layer 2 header and FCS).
ASA IPS 5585-X and Jumbo Packets
The jumbo packet count in the show interface command output from the lines
Please wait while IDM is loading the current configuration from the sensorand
Total Jumbo Packets Receivedfor 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.
Importing a New SSL Certificate
Import the new SSL certificate for the new sensor to each tool being used to monitor the new sensor.

Restrictions and Limitations
The following restrictions and limitations apply to Cisco IPS 7.1(1)E4 software and the products that run it:
•After you upgrade any IPS software on your sensor, you must restart the IDM to see the latest software features.
•Bypass mode is not supported.
•CDP mode is not supported.
•Alternate TCP resets are not supported.
•The ASA 5585-X IPS SSP is supported in ASA 8.2(4.4) and higher as well as ASA 8.4(2) and higher. It is not supported in ASA 8.3(x).
•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.
•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.
•The ASA 5585-X IPS SSP can support both promiscuous and inline monitoring at the same time on its single physical back plane interface inside the adaptive security appliance. The configuration on the main adaptive security appliance can be used to designate which packets/connections should be monitored by the ASA 5585-X IPS SSP as either promiscuous or inline.
•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 the IDM, they are turned into something unrecognizable and you will not be able to delete or edit the resulting object through the IDM or the CLI.
This is true for any string that is used by 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 cannot respond to any queries. Wait a few minutes after reconfiguration is complete before querying SensorApp for additional information.
•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.
•The IDM and the 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.
