Restrictions and Limitations for Configuring Programmability
• Data model related restrictions:
– Only a subset of the IETF, or common data models are supported.
– Only the Cisco device-specific ned.yang model is supported.
– When using ODM models, you must stop and restart the ODM control process if the crypto keys
are regenerated. See Activating and Deactivating the ODM, page 6-17
• DMI solution related restrictions:
– IPv6 is not supported.
– Switches operating in the VSS mode are not supported.
– It is not ISSU-capable.
• Only up to 4 simultaneous NETCONF sessions are supported. Further, a session that is idle for more
than 180 seconds will timeout.
• Requests coming on an EtherChannel that is part of a Layer 3 Switched Virtual Interface (SVI), and
is sharing its IP with the DMI container, is not supported
• AAA remote authentication is not supported.
Zero-Touch Provisioning Requirements
Zero-Touch Provisioning is achieved by using the PXE boot feature. Ensure that you have completed the
following:
• Set the boot field value. See Boot Field, page 6-6
• Configured the DHCP server and an HTTP or TFTP server. See PXE Boot Requirements
—Configuring the DHCP Server, page 6-6 and PXE Boot Process Flow, page 6-7
• Entered the following global configuration commands in the start-up configuration file. This refers
to the <filename>.config file and is downloaded during the PXE boot process. This is required if you
want NETCONF and RESTCONF to be available for use from Day 0.
– The virtual-service DMI command (The virtual service name must be DMI if one opts for
Zero-Touch Provisioning).
– The activate command
– The ip shared host-interface interface-id command
– The onep command
– The service set vty command
– The username name privilege level password password command
To use NETCONF
– The netconf-yang command
To use RESTCONF
– The restconf command
– The ip http server or the ip http secure-server command
– The ip http authentication local command
