Before Installing the AIM IPS
Follow these recommendations before installing the AIM IPS:
•Upgrade or downgrade software when you can take all applications that run on the router out of service or offline.
•Make sure that you have the correct router and software for the module.
•For safety and regulatory information, read Cisco Network Modules and Interface Cards Regulatory Compliance and Safety Information.
•Make a note of the location of the module in the router (slot_number/port_number). The slot value is 0, and the port number field specifies the physical slot number for the AIM IPS (0/IDS-Sensor port).
Note After you install the module, you can get this information by using the show running-config command. You need the module slot number to configure the interfaces on the module.
For More Information
•For the supported routers and software, see Software and Hardware Requirements.
•For more information, refer to Setting Up Interfaces on the AIM IPS and the Router.
Software and Hardware Requirements
The router and the AIM IPS have the following software and hardware requirements:
•The router must be running Cisco IOS release 12.4(15)XY or 12.4(20)T or later.
Note Use the show version command in the router CLI to determine which Cisco IOS release your router is running.
•The module must be running IPS 6.0(3) or later.
Note Use the service-module IDS-Sensor slot/port status command in the IOS CLI to determine which IPS release your sensor is running. Or use the show version command in the module CLI.
–Cisco 1841 and 2801
–Cisco 2800 series (2811, 2821, and 2851)
–Cisco 3800 series (3825 and 3845)
Note The Cisco routers support up to one AIM IPS per platform.
•Supported Cisco IOS Feature Sets:
–Cisco IOS Advanced Security
–Cisco IOS Advanced IP Services
–Cisco IOS Advanced Enterprise Services
Interoperability With Other IPS Modules
You cannot upgrade an NM CIDS to an NME IPS.
The Cisco access routers only support one IDS/IPS module per router. If you have more than one IDS/IPS module installed, the most capable card is enabled. The most capable hierarchy is:
1. NME IPS
2. AIM IPS
3. NM CIDS
This means, for example, that if all modules are installed, the NME IPS disables all other modules. The AIM IPS disables all NM CIDS. If there are multiple modules with the same level of capability, the first one discovered is enabled and all others are disabled.
You cannot bring up, enable, or configure a disabled module. To bring up a less capable module, you must remove the more capable module from the router and reboot. Disabled modules are reported in the show diag command output. The state of the module is reported as present but disabled.
If the most capable module slot and port do not match the interface ids slot/port configuration command, the most capable module is disabled with the following warning:
The module in slot x will be disabled and configuration ignored.
The correct slot/port number are displayed so that you can change the configuration.
For More Information
For more information on NM CIDS, refer to Introducing NM CIDS and Installing NM CIDS.
The following restrictions apply to the AIM IPS:
•Do not deploy IOS IPS and the AIM IPS at the same time.
•When the AIM IPS is used with an IOS firewall, make sure SYN flood prevention is done by the IOS firewall.
The AIM IPS and the IOS firewall complement each other's abilities to create security zones in the network and inspect traffic in those zones. Because the AIM IPS and the IOS firewall operate independently, sometimes they are unaware of the other's activities. In this situation, the IOS firewall is the best defense against a SYN flood attack.
•The Cisco access routers only support one IDS/IPS per router.
•When you reload the router, the AIM IPS also reloads. To ensure that there is no loss of data on the AIM IPS, make sure you shut down the module using the shutdown command before you use the reload command to reboot the router.
For More Information
For more information on which modules work with each other, see Interoperability With Other IPS Modules.
Figure 5-1 shows the router and the AIM IPS interfaces used for internal communication. You can configure the router interfaces through the Cisco IOS CLI and the AIM IPS interfaces through the IPS CLI, IDM, IME, or CSM.
Figure 5-1 AIM IPS and Router Interfaces
Router interface to the AIM IPS (IDS-Sensor 0/1)
Uses the Cisco OS CLI to configure the IP address of the router interface that connects to the AIM IPS. This router IP address is used as the default router IP address when you configure Cisco IPS on the AIM IPS.
The AIM IPS interface to router (GigabitEthernet0/1)
Configure the command and control interface using the IPS CLI, IDM, IME, or CSM.
Router interface to external link.
Note You need two IP addresses to configure the AIM IPS. The AIM IPS has a command and control IP address that you configure through the Cisco IPS CLI. You also assign an IP address to the router for its internal interface (IDS-Sensor 0/x) to the AIM IPS. This IP address belongs to the router itself and is used for routing traffic to the command and control interface of the AIM IPS. It is used as the default router IP address when you set up the AIM IPS command and control interface.

Perform the following tasks after installing the AIM IPS:
1. Verify that the AIM IPS is installed properly.
2. After you install the AIM IPS, you must initialize it.
3. After you initialize the AIM IPS, you should make sure you have the latest IPS software.
4. Configure the AIM IPS to receive IPS Traffic.

Use the show inventory command in privileged EXEC mode to verify the installation of the AIM IPS.
Note You can also use this command to find the serial number of your AIM IPS for use in troubleshooting with TAC. The serial number appears in the PID line, for example, SN: FOC11372M9X.
To verify the installation of the AIM 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 AIM IPS is part of the router inventory.
