IPS v Time and the IDSM-2 You can use one of the two following methods to ensure accurate time on the IDSM-2: Allow the IDSM-2 to automatically synchronize its clock with the switchs time. Configure the IDSM-2 to get its time from an NTP time synchronization source.

12 © 2005 Cisco Systems, Inc. All rights reserved. IPS v Installation and Configuration Tasks Task 1: Install the IDSM-2 in the switch. Task 2: Initialize the IDSM-2. Task 3: Configure the switch for command and control access to the IDSM-2. Task 4: Configure the interfaces.

13 © 2005 Cisco Systems, Inc. All rights reserved. IPS v Task 1: Installing the IDSM-2 in the Switch Step1: Read the Regulatory Compliance and Safety Information for the Intrusion Detection System Appliances and Modules and take the necessary safety precautions. Slot 2: Choose a slot for the module. Step 3: Loosen the installation screws that secure the filler plate to the desired slot. Step 4: Remove the filler plate. Step 5: Hold the module with one hand and place your other hand under the module carrier to support it. Step 6: Align the notch on the sides of the module carrier with the groove in the slot. Step 7: Insert the IDSM-2 into the slot until the notches on both ejector levers engage the chassis sides. Step 8: Fully seat the module in the backplane connector. Step 9: Tighten the installation screws.

14 © 2005 Cisco Systems, Inc. All rights reserved. IPS v Task 2: Initializing the IDSM-2 Step1: Access the IDSM-2 using the switch session command. Step 2: Log in at the IDSM-2 login prompt with the username cisco and the default password cisco. Step 3: Execute the setup command to enter the configuration dialog. Step 4: Enter the network communication parameters. Step 5: Reset the IDSM-2.

15 © 2005 Cisco Systems, Inc. All rights reserved. IPS v Task 3: Configuring the Switch for Command and Control Access to the IDSM-2 Step 1: Log in to the switch. Step 2: Enter privileged mode. Step 3: Assign the command and control port to the correct VLAN.

16 © 2005 Cisco Systems, Inc. All rights reserved. IPS v Task 4: Configuring the Interfaces Step 1: Log in to the switch. Step 2: Enter privileged mode. Step 3: Set the native VLAN for the IDSM-2 sensing ports, 7 and 8. Step 4: Clear all VLANs from each IDSM-2 sensing port except the native VLAN on each port. Step 5: Enable BPDU spanning tree filtering on the IDSM-2 sensing ports.

17 © 2005 Cisco Systems, Inc. All rights reserved. IPS v Configuring the IDSM-2 for Inline Operation Step 1: Configure ports 7 and 8 as a port pair. Step 2: Assign the port pair to the default virtual sensor.

22 © 2005 Cisco Systems, Inc. All rights reserved. IPS v Upgrading the IDSM-2 You can use the upgrade command to apply image upgrades, service packs, and signature updates to your IDSM-2. You can use the upgrade command to upgrade from software version 4. x to 5.0. To upgrade from 4. x to 5.0, the IDSM-2 must already be running IDS 4.1(1) or higher. Using the upgrade command to apply the IPS 5.0 major upgrade file retains your configuration, including signature settings. The IPS 5.0 major upgrade file contains the major upgrade identifier maj. Example: IPS-K9-maj S149.rpm.pkg

26 © 2005 Cisco Systems, Inc. All rights reserved. IPS v Summary The IDSM-2 is a line card for the Cisco Catalyst 6500 Series switches. The IDSM-2 runs the same code as the Cisco IPS sensor appliances. The IDSM-2 supports both inline and promiscuous- mode operations. Sensor initialization tasks specific to the IDSM-2 include the following: –Assigning the command and control port to the proper VLAN –(For promiscuous-mode operations only) Configuring the switch to capture traffic for intrusion detection analysis

27 © 2005 Cisco Systems, Inc. All rights reserved. IPS v Summary (Cont.) The IDSM-2 must obtain its time setting from one of the following: –The host switch –An NTP server If the IDSM-2 obtains its time setting from the host switch, it is important to set the time zone and summertime settings on both the switch and the IDSM-2 to ensure that the GMT time settings are correct.

28 © 2005 Cisco Systems, Inc. All rights reserved. IPS v Summary (Cont.) You can use the CLI upgrade command to apply the IPS 5.0 major upgrade file to the IDSM-2 and retain your configuration. The IDSM-2 has an application partition and a maintenance partition. You can recover the application partition image by booting to the maintenance partition and using the upgrade command to install the IDSM-2 system image. When you install the system image, you lose all your configuration settings.
