show interfaces
Displays information about system interfaces.
Displays information for all interfaces configured on the system.
- counters
- Displays kernel counter information about all the interfaces available on your system.
- detail
- Displays detailed information about all the interfaces available on your system.
- system
- Displays all the physical interfaces available on your system.
- enabled
- Displays only enabled system interfaces known to the operating system kernel.
Operational mode
Use this command to view configuration information and operational status for interfaces and virtual interfaces.
When used with no option, this command displays information for all interfaces configured on the system. You can see specific information by using other versions of this command.
To see all the physical interfaces known to the operating system kernel, use the system option. This option differs from the other versions of this command; the other versions show interfaces that have been configured on the system, while the system option shows all the physical interfaces available on your system (that is, the physical interfaces known to the operating system kernel).
The physical interfaces available to you determine which interfaces you are able to configure and view because you cannot configure or view an interface that does not physically exist on the system.
The following example shows how to display information for interfaces.
vyatta@R1:~$ show interfaces
Codes: S - State, L - Link, u - Up, D - Down, A - Admin Down
