Managing network device virtual interface discovery
BMC Discovery has the ability to discover network device virtual interfaces. By default, this ability is disabled as some devices have very many virtual interfaces and their discovery can have a significant performance impact. However, discovering network device virtual interfaces does add the capability of linking network interface nodes to IP address nodes.
You can manage network device virtual interface discovery by using the tw_options
command.
Warning
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 Discovery behavior.
Enabling network device virtual interface discovery
To enable network device virtual interface discovery:
- Log in to the appliance command line as the
tideway
user. - Enable network device virtual interface discovery using either the system user or another user belonging to the system or admin group:
If using the system user:
[tideway@localhost ~]$ tw_options NETWORK_DISCOVERY_VIRTUAL_INTERFACES=True
If using another user (other than the system user) belonging to the system or admin group:
tw_options -u <user name> NETWORK_DISCOVERY_VIRTUAL_INTERFACES=True
When prompted, depending on the command you have run in the previous step, enter the system or user's UI password.
- 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:
- Log in to the appliance command line as the
tideway
user. - Disable network device virtual interface discovery using either system user or another user belonging to the system or admin group:
If using the system user:
[tideway@localhost ~]$ tw_options NETWORK_DISCOVERY_VIRTUAL_INTERFACES=False
If using another user (other than the system user) belonging to the system or admin group:
tw_options -u <user name> NETWORK_DISCOVERY_VIRTUAL_INTERFACES=False
When prompted, depending on the command you have run in the previous step, enter the system or user's UI password.
- Exit from the command line prompt.
