Configuring IDS
Using the CLI to Configure IDS Signatures
Follow these steps to configure IDS signatures using the controller CLI.
Step 1 If desired, create your own custom signature file.
Step 2 Make sure that you have a TFTP server available. See the guidelines for setting up a TFTP server in
Step 2 of the “Using the GUI to Upload or Download IDS Signatures” section on page 5-69.
Step 3 Copy the custom signature file (*.sig) to the default directory on your TFTP server.
Step 4 To specify the download or upload mode, enter transfer {download | upload} mode tftp.
Step 5 To specify the type of file to be downloaded or uploaded, enter transfer {download | upload} datatype
signature.
Step 6 To specify the IP address of the TFTP server, enter transfer {download | upload} serverip
tftp-server-ip-address.
Note Some TFTP servers require only a forward slash (/) as the TFTP server IP address, and the TFTP
server automatically determines the path to the correct directory.
Step 7 To specify the download or upload path, enter transfer {download | upload} path
absolute-tftp-server-path-to-file.
Step 8 To specify the file to be downloaded or uploaded, enter transfer {download | upload} filename
filename.sig.
Note When uploading signatures, the controller uses the filename you specify as a base name and then
adds “_std.sig” and “_custom.sig” to it in order to upload both standard and custom signature
files to the TFTP server. For example, if you upload a signature file called “ids1,” the controller
automatically generates and uploads both ids1_std.sig and ids1_custom.sig to the TFTP server.
If desired, you can then modify ids1_custom.sig on the TFTP server (making sure to set
“Revision = custom”) and download it by itself.
Step 9 Enter transfer {download | upload} start and answer y to the prompt to confirm the current settings
and start the download or upload.
Step 10 To enable or disable IDS signatures, perform one of the following:
To enable or disable an individual IDS signature, enter this command:
config wps signature {standard | custom} state signature_id {enable | disable}
To enable or disable IDS signature processing, which enables or disables the processing of all IDS
signatures, enter this command:
config wps signature {enable | disable}
Note If IDS signature processing is disabled, all signatures are disabled, regardless of the state
configured for individual signatures.
