Configuring the NME IPS
Note All IPS platforms allow ten concurrent CLI sessions.
This chapter describes how to configure the NME IPS and get it ready to receive IPS traffic. After that you are ready to configure intrusion prevention.This chapter contains the following sections:
•NME IPS Configuration Sequence
•Verifying Installation and Finding the Serial Number
•NME IPS Hardware Interfaces
•Setting Up Interfaces on the NME IPS and the Router
•Establishing Sessions
•Opening and Closing a Session
•Displaying the Status of the NME IPS
•Enabling and Disabling Heartbeat Reset
•Rebooting, Resetting, and Shutting Down the NME IPS
•New and Modified Commands
NME IPS Configuration Sequence
Perform the following tasks to configure the NME IPS:
1. Set up the interfaces.
2. Log in to the NME IPS.
3. Initialize the NME IPS. Run the setup command to initialize the NME IPS.
4. Configure the NME IPS to capture traffic for intrusion prevention.
5. Create the service account.
Caution
You should carefully consider whether you want to create a service account. The service account provides shell access to the system, which makes the system vulnerable. However, you can use the service account to create a new password if the administrator password is lost. Analyze your situation to decide if you want a service account existing on the system.
6. Perform the other initial tasks, such as adding users, trusted hosts, and so forth.
7. Configure intrusion prevention.
8. Configure global correlation.
9. Perform administrative tasks to keep your NME IPS running smoothly.
10. Upgrade the IPS software with new signature updates and service packs.
11. Reimage the boot helper and bootloader when needed.

Verifying Installation and Finding the Serial Number
Use the show inventory command in privileged EXEC mode to verify the installation of the NME IPS.
Note You can also use this command to find the serial number of your NME IPS for use in troubleshooting with TAC. The serial number appears in the PID line, for example, SN: FHH1117001R.
To verify the installation of the NME IPS, follow these steps:
Step 1 Log in to the router.
Step 2 Enter privileged EXEC mode on the router.
Step 3 Verify that the NME IPS is part of the router inventory.

Setting Up Interfaces on the NME IPS and the Router
This section describes how to set up interfaces on the NME IPS and the router, contains the following topics:
•The NME IPS Interface Configuration Sequence
•Advantages of NAT
•ARC and NAT
•Configuring the IDS-Sensor Interfaces on the Router
•Configuring Monitoring on the Router Interface
The NME IPS Interface Configuration Sequence
Follow this sequence to set up interfaces on the NME IPS and the router:
1. Configure the IPS command and control interface on the router, and the NME IPS IP address, mask, and gateway.
2. Enable the monitoring interface and specify whether it is promiscuous or inline, assign the ACL to the interface, specify how you want the router to handle traffic if the module fails, and create a monitoring ACL (optional).
3. Save the configuration.
For More Information
•For the procedure for configuring an unnumbered IP address on the IDS-Sensor interface, see Configuring the IDS-Sensor Interfaces on the Router.
•For the procedure for enabling the monitoring interface, see Configuring Monitoring on the Router Interface.
Advantages of NAT
NAT has the following advantages:
•You can use private IP addresses on your inside networks. Private IP addresses are not routable on the Internet.
•NAT hides the local IP addresses from other networks, so attackers cannot learn the real IP address of a host.
•NAT can resolve IP routing problems by supporting overlapping IP addresses.
For More Information
For information on how ARC and NAT operate together, see ARC and NAT.
ARC and NAT
If you use NAT to establish management access to the NME IPS, ARC on the NME IPS does not know the external IP address of the NME IPS. To make sure that management access to the NME IPS is not interrupted by devices that the NME IPS is managing, you must state the NAT address of the NME IPS every time you add a blocking device.
For More Information
•For more information on ARC, see Chapter 14 "Configuring Attack Response Controller for Blocking and Rate Limiting."
•For the procedures for configuring the NME IPS NAT address every time you add a blocking device, see the following procedures:
–Configuring the Sensor to Manage Cisco Routers
–Configuring the Sensor to Manage Catalyst 6500 Series Switches and Cisco 7600 Series Routers
–Configuring the Sensor to Manage Cisco Firewalls
Configuring the IDS-Sensor Interfaces on the Router
To configure the NME IPS interfaces, follow these steps:
Step 1 Log in to the router.
Step 2 Enter privileged EXEC mode on the router.
Step 3 Confirm the module slot number in your router.
router# show run | include ids-sensor
Step 4 Enable the CEF switching path.
router> configuration terminal
Step 5 Create a loopback interface.
router(config)# interface loopback 0
Step 6 Assign an IP address and netmask to the loopback interface.
router(config-if)# ip address 10.99.99.99 255.255.255.255
Note You must assign an IP address to the internal interface of the NME IPS to session in to the NME IPS. Choose a network that does not overlap with any networks assigned to the other interfaces in the router.
Step 7 Assign an unnumbered loopback interface to the IDS-Sensor interface. Use slot 1 for this example.
router(config)# interface ids-sensor 1/0
router(config-if)# ip unnumbered Loopback 0
Step 8 Activate the port.
router(config-if)# no shutdown
Step 9 Exit configuration mode.
Step 10 Write the configuration to NVRAM.
You are now ready to initialize the NME IPS and configure intrusion prevention.
For More Information
•For more information on sessioning from the router to the NME IPS and exiting sessions, see Establishing Sessions.
•For the procedure for using the setup command to initialize the NME IPS, see Advanced Setup for the NME IPS.
•For the procedures for configuring intrusion prevention, refer to the following IPS guides:
–Cisco Intrusion Prevention System Device Manager Configuration Guide for IPS 7.0
–Cisco Intrusion Prevention System Manager Express Configuration Guide for IPS 7.0
–Cisco Intrusion Prevention System Sensor CLI Configuration Guide for IPS 7.0
Configuring Monitoring on the Router Interface
To configure the router interface to be monitored, follow these steps:
Step 1 Log in to the router.
Step 2 Enter privileged EXEC mode on the router.
Step 3 (Optional) Configure a monitoring access list on the router.
router(config)# access-list 101 permit tcp any eq www any
You can set up a standard access list and apply it to filter what type of traffic you want to inspect. A matched ACL causes traffic not to be inspected for that ACL. This example bypasses inspection of HTTP traffic only. Refer to your Cisco IOS Command Reference for more information on the options for the access-list command.
Step 4 Enable monitoring on the interface in either inline or promiscuous mode and associate the access list.
router(config)# interface monitored_interface
router(config-if)# ids-service-module monitoring {inline | promiscuous} access-list 101
Note Associating the access list with the interface further controls what traffic is sent to the NME IPS.
Step 5 (For inline mode) Confirm the module slot number in your router.
router# show run | include ids-sensor
Step 6 (For inline mode) Specify how the router handles traffic inspection during a module failure.
router(config)# interface ids-sensor 1/0
router(config-if)# service-module {fail-close | fail-open}
The default is fail-open.
Note The fail-close option means that if the NME IPS fails, then the router does not let traffic pass. The fail-open option means if the NME IPS fails, the router lets traffic pass, but it is not inspected by the IPS.
Step 7 Exit configuration mode.
Step 8 Write the configuration to NVRAM.
For More Information
•For more information on promiscuous mode, see Configuring Promiscuous Mode.
•For more information on inline interface mode, see Configuring Inline Interface Mode.
Establishing Sessions
Because the NME IPS does not have an external console port, console access to the NME IPS is enabled when you issue the service-module ids-sensor slot/port session command on the router, or when you initiate a Telnet connection into the router with the slot number corresponding to the NME IPS port number. The lack of an external console port means that the initial bootup configuration is possible only through the router.
When you issue the service-module ids-sensor slot/port session command, you create a console session with the NME IPS, in which you can issue any IPS configuration commands. After completing work in the session and exiting the IPS CLI, you are returned to the Cisco IOS CLI.
The session command starts a reverse Telnet connection using the IP address of the IDS-Sensor interface. The IDS-Sensor interface is an interface between the NME IPS and the router. You must assign an IP address to the IDS-Sensor interface before invoking the session command. Assigning a routable IP address can make the IDS-Sensor interface itself vulnerable to attacks, because the NME IPS is visible on the network through that routable IP address, meaning you can communicate with the NME IPS outside the router. To counter this vulnerability, assign an unnumbered IP address to the IDS-Sensor interface. Then the NME IPS IP address is only used locally between the router and the NME IPS, and is isolated for the purposes of sessioning in to the NME IPS.
Note Before you install your application software or reimage the module, opening a session brings up the bootloader. After you install the software, opening a session brings up the application.
Caution
If you session to the module and perform large console transfers, character traffic may be lost unless the host console interface speed is set to 115200/bps or higher. Use the
show running config command to check that the speed is set to 115200/bps.
For More Information
For the procedure for configuring the IDS-Sensor interfaces, see Configuring the IDS-Sensor Interfaces on the Router.
Opening and Closing a Session
Note You must initialize the NME IPS (run the setup command) from the router. After networking is configured, SSH and Telnet are available.
Use the service-module ids-sensor slot/port session command to establish a session from the NME IPS to the module. Press Ctrl-Shift-6, then x, to return a session prompt to a router prompt, that is, to go from the NME IPS prompt back to the router prompt. Press Enter on a blank line to go back to the session prompt, which is also the router prompt. You should only suspend a session to the router if you will be returning to the session after executing router commands. If you do not plan on returning to the NME IPS session, you should close the session rather than suspend it.
When you close a session, you are logged completely out of the NME IPS CLI and a new session connection requires a username and password to log in. A suspended session leaves you logged in to the CLI. When you connect with the session command, you can go back to the same CLI without having to provide your username and password.
Note Telnet clients vary. In some cases, you may have to press Ctrl-6 + x. The control character is specified as ^^, Ctrl-^, or ASCII value 30 (hex 1E).
Caution
If you use the
disconnect command to leave the session, the session remains running. The open session can be exploited by someone wanting to take advantage of a connection that is still in place.
To open and close sessions to the NME IPS, follow these steps:
Step 1 Log in to the router.
Step 2 Check the status of the NME IPS to make sure it is running.
router# service-module ids-sensor 1/0 status
Service Module is Cisco IDS-Sensor1/0
Service Module supports session via TTY line 130
Service Module is in Steady state
Service Module heartbeat-reset is disabled
Getting status from the Service Module, please wait..
Cisco Systems Intrusion Prevention System Network Module
Software version: 6.2(1)E3
Mgmt IP addr: 10.89.148.195
Step 3 Open a session from the router to the NME IPS.
router# service-module ids-sensor 1/0 session
Trying 10.89.148.195, 2322 ... Open
Step 4 Exit, or suspend and close the module session:
•sensor#
exit
Note If you are in submodes of the IPS CLI, you must exit all submodes. Enter exit until the sensor login prompt appears.
Caution
Failing to close a session properly makes it possible for others to exploit a connection that is still in place. Remember to enter
exit at the
router#
prompt to close the Cisco IOS session completely.
•To suspend and close the session to the NME IPS, press Ctrl-Shift and press 6. Release all keys, and then press x.
Note When you are finished with a session, you need to return to the router to establish the association between a session (the IPS application) and the router interfaces you want to monitor.
Step 5 Disconnect from the router.
Step 6 Press Enter to confirm the disconnection.
router# Closing connection to 10.89.148.196 [confirm] <Enter>
For More Information
For the procedure for initializing the NME IPS, see Advanced Setup for the NME IPS.
Displaying the Status of the NME IPS
Use the service-module ids-sensor slot/port status command in privileged EXEC mode to display the status and statistics of the NME IPS.
To display the status of the NME IPS, follow these steps:
Step 1 Log in to the router.
Step 2 Enter privileged EXEC mode on the router.
Step 3 Display the status of the NME IPS.
router# service-module ids-sensor 1/0 status

Mgmt IP addr: 10.89.148.195
Enabling and Disabling Heartbeat Reset
Use the service-module ids-sensor slot/port heartbeat reset {enable | disable} command in privileged EXEC mode to reset the heartbeat of the NME IPS.
When the NME IPS is booted in failsafe mode or is undergoing an upgrade, you can use the service-module ids heartbeat-reset command to prevent a reboot during the process. If you leave the heartbeat reset enabled during an upgrade, you may lose the NME IPS heartbeat.
When the NME IPS heartbeat is lost, the router applies a fail-open or fail-close configuration option to the NME IPS and stops sending traffic to the NME IPS, and sets the NME IPS to error state. The router performs a hardware reset on the NME IPS and monitors the NME IPS until the heartbeat is reestablished.
Note Disabling the heartbeat reset prevents the router from resetting the module during system image installation if the process takes too long.
To reset the heartbeat of the NME IPS, follow these steps:
Step 1 Log in to the router.
Step 2 Enter privileged EXEC mode on the router.
Step 3 Verify the status of heartbeat reset.
router# service-module ids-sensor 1/0 status
Service Module is Cisco IDS-Sensor 1/0
Service Module supports session via TTY line 194
Service Module heartbeat-reset is enabled
Step 4 To disable the heartbeat on the NME IPS:
router# service-module ids-sensor 1/0 heartbeat-reset disable
Step 5 To reenable the heartbeat on the NME IPS:
router# service-module ids-sensor 1/0 heartbeat-reset enable

Rebooting, Resetting, and Shutting Down the NME IPS
This section describes when and how the NME IPS shuts down. It contains the following topics:
•NME IPS Status Monitoring
•Rebooting, Resetting, and Shutting Down the NME IPS
NME IPS Status Monitoring
The NME IPS uses RBCP to monitor its status. RBCP is monitored by the main application on the NME IPS, not by SensorApp. If the main application on the NME IPS fails, the RBCP heartbeat responses do not return from the NME IPS. When the router determines that the NME IPS has failed, a reload command is issued through RBCP to reboot the Linux kernel on the NME IPS. In the period during the attempt to bring the NME IPS back up, the router works in the mode determined by the failover operation configured.
In some cases, SensorApp may stop processing, but the main application on the NME IPS continues to process RBCP packets. In this case, packets are processed according to the bypass settings set for the NME IPS by the IPS CLI, IDM, or IME.
There are two situations in which the NME IPS shuts down:
•A hardware or software error forces it to fail. The router can detect this through the loss of the RBCP heartbeat.
•Reload or shutdown command.
For More Information
•For more information on SensorApp, see SensorApp.
•For more information on software bypass, see Configuring Inline Bypass Mode.
Rebooting, Resetting, and Shutting Down the NME IPS
Use the service-module ids-sensor slot/port [reload | reset | shutdown] command in privileged EXEC mode to reboot, reset, and shut down the NME IPS.
To reboot, reset, and shut down the NME IPS, follow these steps:
Step 1 Log in to the router.
Step 2 Enter privileged EXEC mode on the router.
Step 3 To gracefully halt and reboot the operating system on the NME IPS:
router# service-module ids-sensor 1/0 reload
Do you want to proceed with the reload? [confirm]
Step 4 To reset the hardware on the NME IPS:
router# service-module ids-sensor 1/0 reset
Use reset only to recover from shutdown or failed state
Warning: May lose data on the hard disc!
Do you want to reset?[confirm]
Note The NME IPS has a compact flash device that functions as a permanent storage device rather than a hard-disk drive.
Caution
Data loss occurs only if you issue the
reset command without first shutting down the NME IPS. You can use the
reset command safely in other situations.
Step 5 To shut down applications running on the NME IPS:
router# service-module ids-sensor 1/0 shutdown
Trying 10.10.10.1, 2129 . . . Open
%SERVICEMODULE-5-SHUTDOWN2:Service module IDS-Sensor1/0 shutdown complete

Usage Guidelines
When the NME IPS is booted in failsafe mode or is undergoing an upgrade, you can use the service-module ids heartbeat-reset command to prevent a reboot during the process. If you leave the heartbeat reset enabled during an upgrade, you may lose the NME IPS heartbeat.
When the NME IPS heartbeat is lost, the router applies a fail-open or fail-close configuration option to the NME IPS and stops sending traffic to the NME IPS, and sets the NME IPS to error state. The router performs a hardware reset on the NME IPS and monitors the NME IPS until the heartbeat is reestablished.
If a confirmation prompt is displayed, press Enter to confirm the action or n to cancel.
Examples
The following example demonstrates how to disable or enable the reset action when the heartbeat is lost on an NME IPS in slot 1, port 0:
