Determining the Security Interface link speed and duplex on a Security Network IPS sensor

Important: When performing administration tasks via ssh or local console, configuration changes made to your IBM appliance by any user other than admin could degrade appliance performance. Installing or activating other services or applications may also impact appliance performance or security. IBM Infrastructure Security Support will not support configuration changes made using the root user account unless specifically directed by a support engineer or IBM documentation. The following DCF Technote content is supported. Any further changes made that are not included in this document will place your product into an unsupported state and IBM product support may require you to reimage your appliance to restore it to a supported state.

This article explains how to determine the link speed and duplex for the protection interfaces on a GX IPS appliance. This information is useful when trying to determine the speed and duplex mode that a link has been assigned through auto-negotiation.

Note: Adapterdump does not work on GX6116 devices. See Technote 1436849: Viewing driver statistics on GX6116 when it does not support the adapterdump command for information on how to obtain driver statistics for the the GX6116.
 

1. Log in to the GX appliance using the root account via the SSH or console connection.
    
2. Enter the following command to change the directory:
   
   cd /etc/iss/drivers/
    
3. The /etc/iss/drivers/ directory contains a script called adapterdump that you must run. Using the -i switch will cause it to grab only the necessary information for determining link and duplex settings. The complete command is as follows:
   
   ./adapterdump -i
    
4. The script output will display the interface settings for each of the protection ports. To interpret the output, use the following guide:
   
   Dev[0] corresponds to port 1A
   Dev[1] corresponds to port 1B
   and so on
