Before Installing AIM IPS

Follow these recommendations before installing 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). For AIM IPS, the slot value is 0, and the port number field specifies the physical slot number for 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 the procedure for configuring module interfaces, refer to Setting Up Interfaces on AIM IPS and the Router.

Software and Hardware Requirements

The router and 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.


AIM IPS 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 AIM IPS CLI.


Supported routers:

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

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. AIM IPS

2. NM-CIDS

This means, for example, that if both modules are installed, AIM IPS disables the 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.

Restrictions

The following restrictions apply to AIM IPS:

Do not deploy IOS IPS and AIM IPS at the same time.

When AIM IPS is used with an IOS firewall, make sure SYN flood prevention is done by the IOS firewall.

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 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.


Caution When you reload the router, AIM IPS also reloads. To ensure that there is no loss of data on 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 how the modules operate together, see Interoperability With Other IPS Modules.

For more information about shutting down AIM IPS, refer to Rebooting, Resetting, and Shutting Down AIM IPS.

Hardware Interfaces

Figure 7-1 shows the router and 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 or IDM.

Figure 7-1 AIM IPS and Router Interfaces

1

Router interface to AIM IPS (IDS-Sensor 0/1 or IDS-Sensor0/0, depending on which slot AIM IPS occupies, 0 or 1)
Uses the Cisco OS CLI to configure the IP address of the router interface that connects to AIM IPS. This router IP address is used as the default router IP address when you configure Cisco IPS on AIM IPS.

2

AIM IPS interface to router (GigabitEthernet0/1)
Configure the command and control interface using the IPS CLI or IDM.

3

Router interface to external link.



Note You need two IP addresses to configure AIM IPS. 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 AIM IPS. This IP address belongs to the router itself and is used for routing traffic to the command and control interface of AIM IPS. It is used as the default router IP address when you set up the AIM IPS command and control interface.


For More Information

Perform the following tasks after installing AIM IPS:

1. Verify that AIM IPS is installed properly.

2. After you install AIM IPS, you must initialize it.

3. After you initialize AIM IPS, you should make sure you have the latest IPS software.

4. Configure AIM IPS to receive IPS Traffic.

Verifying Installation

Use the show inventory command in privileged EXEC mode to verify the installation of 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 AIM IPS, follow these steps:


Step 1 Log in to the router.

Step 2 Enter privileged EXEC mode on the router:

router> enable
 
   

Step 3 Verify that AIM IPS is part of the router inventory:

router#show inventory
