Supported Interface Types

The following table shows the syntax and parameters of supported interface types. Depending on the command, some of these types may not apply.

Table 1. Supported interface types
Interface Type Syntax Parameters



brx: The name of a bridge group. The name ranges from br0 through br999.

Data plane


interface-name: The name of a data plane interface. Following are the supported formats of the interface name:

  • dpxpypz—The name of a data plane interface, where

    dpx specifies the data plane identifier (ID). Currently, only dp0 is supported.

    — py specifies a physical or virtual PCI slot index (for example, p129).

    pz specifies a port index (for example, p1). For example, dp0p1p2, dp0p160p1, and dp0p192p1.

  • dpxemy —The name of a data plane interface on a LAN-on-motherboard (LOM) device that does not have a PCI slot, where emy specifies an embedded network interface number (typically, a small number). For example, dp0em3.
  • dpxsy—The name of a data plane interface in a system in which the BIOS identifies the network interface card to reside in a particular physical or virtual slot y, where y is typically a small number. For example, for the dp0s2 interface, the BIOS identifies slot 2 in the system to contain this interface.
  • dpxPnpypz —The name of a data plane interface on a device that is installed on a secondary PCI bus, where Pn specifies the bus number. You can use this format to name data plane interfaces on large physical devices with multiple PCI buses. For these devices, it is possible to have network interface cards installed on different buses with these cards having the same slot ID. The value of n must be an integer greater than 0. For example, dp0P1p162p1 and dp0P2p162p1.

Data plane vif

dataplane interface-name vif vif-id [vlan vlan-id ]

interface-name: Refer to the preceding description.

vif-id: A virtual interface ID. The ID ranges from 1 through 4094.

vlan-id: The VLAN ID of a virtual interface. The ID ranges from 1 through 4094.


loopback lo


loopback lon

n: The name of a loopback interface, where n ranges from 1 through 99999.



vtunx: The identifier of an OpenVPN interface. The identifier ranges from vtun0 through vtunx, where x is a nonnegative integer.





tunx: The identifier of a tunnel interface you are defining. The identifier ranges from tun0 through tunx, where x is a nonnegative integer.

Virtual tunnel


vtix: The identifier of a virtual tunnel interface you are defining. The identifier ranges from vti0 through vtix, where x is a nonnegative integer.

Note: Before you can configure a vti interface, you must configure a corresponding vpn.

Note: This interface does not support IPv6.


parent-interface vrrpvrrp-groupgroup

parent-interface: The type and identifier of a parent interface; for example, data plane dp0p1p2 or bridge br999.

group: A VRRP group identifier.

The name of a VRRP interface is not specified. The system internally constructs the interface name from the parent interface identifier plus the VRRP group number; for example, dp0p1p2v99. Note that VRRP interfaces support the same feature set as does the parent interface.
