Interfaces

Module for working with interfaces in EOS

This module provides an API for pragmatically working with EOS interface configurations. Interfaces include any data or management plane interface available in EOS.

param name:

The name of the interface the configuration should be applied to. The interface name is the full interface identifier.

type name:

string

param shutdown:

True if the interface is administratively disabled, and False if the interface is administratively enable. This value does not validate the interfaces operational state.

type shutdown:

boolean

param description:

The interface description string. This value is an arbitrary operator defined value.

type description:

string

param sflow:

True if sFlow is enabled on the interface otherwise False

type sflow:

boolean

param flowcontrol_send:

The flowcontrol send configuration value for the interface. Valid values are on or off

type flowcontrol_send:

string

param flowcontrol_receive:

The flowcontrol receive configuration value for the interface. Valid values are on or off

type flowcontrol_receive:

string

class pyeapi.api.interfaces.BaseInterface(node)

Bases: EntityCollection

create(name)

Creates a new interface on the node

Note

This method will attempt to create the interface regardless if the interface exists or not. If the interface already exists then this method will still return True

Parameters:

name (string) – The full name of the interface.

Returns:

True if the interface could be created otherwise False (see Note)

default(name)

Defaults an interface in the running configuration

Parameters:

name (string) – The full name of the interface

Returns:

True if the command operation succeeds otherwise False

delete(name)

Deletes the interface from the node

Note

This method will attempt to delete the interface from the nodes operational config. If the interface does not exist then this method will not perform any changes but still return True

Parameters:

name (string) – The full name of the interface

Returns:

True if the interface could be deleted otherwise False (see Node)

get(name)

Returns a generic interface as a set of key/value pairs

This class is should normally serve as a base class for building more specific interface resources. The attributes of this resource are common to all interfaces regardless of type in EOS.

The generic interface resource returns the following:

• name (str): The name of the interface

• type (str): Always returns ‘generic’

• shutdown (bool): True if the interface is shutdown

• description (str): The interface description value

Parameters:

name (str) – The interface identifier to retrieve from the running-configuration

Returns:

A Python dictionary object of key/value pairs that represents

the interface configuration. If the specified interface does not exist, then None is returned

set_description(name, value=None, default=False, disable=False)

Configures the interface description

EosVersion:

4.13.7M

Parameters:

• name (string) – The interface identifier. It must be a full interface name (ie Ethernet, not Et)

• value (string) – The value to set the description to.

• default (boolean) – Specifies to default the interface description

• disable (boolean) – Specifies to negate the interface description

Returns:

True if the operation succeeds otherwise False

set_encapsulation(name, vid, default=False, disable=False)

Returns:

True if the operation succeeds otherwise False is returned

set_shutdown(name, default=False, disable=True)

Configures the interface shutdown state

Default configuration for set_shutdown is disable=True, meaning ‘no shutdown’. Setting both default and disable to False will effectively enable shutdown on the interface.

Parameters:

• name (string) – The interface identifier. It must be a full interface name (ie Ethernet, not Et)

• default (boolean) – Specifies to default the interface shutdown

• disable (boolean) – Specifies to disable interface shutdown, i.e. disable=True => no shutdown
