Configuring Subinterfaces Using Python Client for eAPI

Subinterfaces can be configured on Ethernet and Port-Channel interfaces. To do this in pyeapi simply call create or delete with your subinterface name.

Subinterfaces require that the primary interface be in routed mode.

import pyeapi
node = pyeapi.connect_to('veos01')
node.api('ipinterfaces').create('Ethernet1')

At this point the below should be in your running configuration.

!
interface Ethernet1
   no switchport
!

Next step is to create the subinterface

node.api('interfaces').create('Ethernet1.1')

!
interface Ethernet1
   no switchport
!
interface Ethernet1.1
!

Subinterfaces also require a vlan to be applied to them.

node.api('interfaces').set_encapsulation('Ethernet1.1', 4)

!
interface Ethernet1
   no switchport
!
interface Ethernet1.1
   encapsulation dot1q vlan 4
!

Using delete in the same format as create will remove the subinterface.

For more detailed information about configuring subinterfaces in EOS, reference the user manual for the version of EOS running on your switch.
