Question

A network engineer must update the description of an existing VLAN (VLAN 100) on a Cisco IOS XE device using RESTCONF (RFC 8040). The device exposes the ietf-vlan and Cisco-IOS-XE-native YANG models. The engineer wants to modify ONLY the description leaf of VLAN 100 without affecting any other configured attributes of that VLAN or replacing the entire VLAN resource. Which HTTP method and target URI approach should the engineer use?

Accepted Answer

Send a PATCH request to the URI targeting the specific VLAN list entry (.../vlan/vlan-list=100) with a body containing only the description leaf

Answer

Send a PUT request to the URI targeting the entire VLAN container (.../vlan) with a body containing all VLAN definitions

Answer

Send a POST request to the URI targeting the specific VLAN list entry (.../vlan/vlan-list=100) with a body containing only the description leaf

Answer

Send a DELETE request to the description leaf followed by a POST to recreate it with the new value
