R1config interface fa01 R1config-if ip ips iosips in Step 8: Verify the IOS IPS signature package location and TFTP server setup a. Verify connectivity between R1 and PC-A, the TFTP server. b. Verify that the PC has the IPS signature package file in a directory on the TFTP server. This file is typically named IOS-Sxxx-CLI.pkg, where xxx is the signature file version. Note: Use the newest signature file available if the router memory can support it. If a signature file is not present, contact your instructor before continuing. c. Start the TFTP server and set the default directory to the one that contains the IPS signature package. Step 9: Copy the signature package from the TFTP server to the router. a. Use the copy tftp command to retrieve the signature file. Be sure to use the idconf keyword at the end of the copy command. Note: Immediately after the signature package is loaded to the router, signature compiling begins. Allow time for this process to complete. It can take several minutes. R1 copy tftp:192.168.1.3IOS-S364-CLI.pkg idconf b. Display the contents of the ipsdir directory created earlier.

Task 11: Configure IPS on R3 Using CCP Chapter 5 Step 1: Optional Install the TFTP server on PC-C. If a TFTP server is not currently installed on PC-C, download Tftpd32 from http:tftpd32.jounin.net and install it on your desktop. If it is already installed, go to Step 2. Step 2: Prepare the router and TFTP server. To configure Cisco IOS IPS 5.x, the IOS IPS signature package file and public crypto key files must be available on PC-C. Check with your instructor if these files are not on the PC. These files can be downloaded from Cisco.com with a valid user account that has proper authorization. a. Verify that the IOS-Sxxx-CLI.pkg signature package file is in a TFTP folder. The xxx is the version number and varies depending on which file was downloaded. Note: Use the newest signature file available if the router memory can support it. If a signature file is not present, contact your instructor before continuing. b. Verify that the realm-cisco.pub.key.txt file is available and note its location on PC-C. This is the public crypto key used by Cisco IOS IPS. c. Verify or create the IPS directory in router flash on R1. From the R1 CLI, display the content of flash memory and check to see if the ipsdir directory exists.
