Managing network device virtual interface discovery

BMC Atrium Discovery has the ability to discover network device virtual interfaces. By default, this ability is disabled. You can manage network device virtual interface discovery by using the tw_options command.

Use of the tw_options command is strictly restricted to managing network device virtual interface discovery and managing attachments only. Unless explicitly instructed by BMC Support, you must not change any other tw_options options as it may result in unexpected BMC Atrium Discovery behavior.

Enabling network device virtual interface discovery

To enable network device virtual interface discovery:

  1. Log in to the appliance command line as the tideway user.
  2. You must use the system user, or another user belonging to the system or admin group to be able to enable network device virtual interface discovery.
    • If using the system user, enter:

      [tideway@localhost ~]$ tw_options NETWORK_DISCOVERY_VIRTUAL_INTERFACES=True
    • If you are using another user (other than the system user) belonging to the system or admin group, enter:

      tw_options -u <user name> NETWORK_DISCOVERY_VIRTUAL_INTERFACES=True
  3. When prompted, depending on the command you have run in the previous step, enter the system or user's UI password. 

  4. Exit from the command line prompt.

Disabling network device virtual interface discovery

If network device virtual interface discovery has been enabled and you want to disable it, you must: 

  1. Log in to the appliance command line as the tideway user.
  2. You must use the system user, or another user belonging to the system or admin group to be able to disable network device virtual interface discovery.
    • If using the system user, enter:

      [tideway@localhost ~]$ tw_options NETWORK_DISCOVERY_VIRTUAL_INTERFACES=False
    • If you are using another user (other than the system user) belonging to the system or admin group, enter:

      tw_options -u <user name> NETWORK_DISCOVERY_VIRTUAL_INTERFACES=False
  3. When prompted, depending on the command you have run in the previous step, enter the system or user's UI password.

  4. Exit from the command line prompt.
