SR OS routers can be in different management interface configuration modes, which affects the management interfaces that can be used to configure the router. The following interfaces are available for configuration on SR OS:
classic (default)
Configuration via the classic CLI and SNMP, no model-driven interfaces are supported.
model-driven
Configuration via model-driven interfaces: the MD-CLI, NETCONF, and gRPC/gNMI, read-only access via the classic CLI and SNMP.
mixed
Configuration via the classic CLI and model-driven interfaces: the MD-CLI, NETCONF, and gRPC/gNMI, read-only access via SNMP.
Use the configure system management-interface configuration-mode command to enable configuration editing by model-driven interfaces.
Mixed configuration mode is useful for operators to migrate from classic management interfaces to operating in a full model-driven mode. It allows the use of previous classic CLI scripts or other OSS integration for configuration, although with some pre-requisites (see Prerequisites for using model-driven management interfaces) and some limitations (see Table: Management interface configuration mode).
