Loopback Interface Models

Overview

The Loopback Interface models provide structured validation for loopback interface configuration. Loopback interfaces support IPv4 and IPv6 addressing for management and service endpoints.

Models

LoopbackInterfaceCreateModel: For creating new loopback interfaces
LoopbackInterfaceUpdateModel: For updating existing interfaces (includes id)
LoopbackInterfaceResponseModel: Response model from API operations

All models use extra="forbid" to reject undefined fields.

Model Attributes

LoopbackInterfaceBaseModel

Attribute	Type	Required	Default	Description

Usage Examples

Create with IPv4

from scm.models.network import LoopbackInterfaceCreateModel

loopback = LoopbackInterfaceCreateModel(
    name="loopback.1",
    ip=["10.0.0.1/32"],
    interface_management_profile="allow-ping",
    folder="Interfaces"
)
payload = loopback.model_dump(exclude_unset=True)

Create with IPv6

loopback = LoopbackInterfaceCreateModel(
    name="loopback.2",
    ip=["192.168.1.1/32"],
    ipv6={
        "enabled": True,
        "address": [{"name": "2001:db8::1/128"}]
    },
    folder="Interfaces"
)
