  title: Cisco Expressway Provision DNS Server
  summary: Add a DNS server to an Expressway node and confirm it was applied.
  description: >-
    Adds a new DNS server address to the Cisco Expressway common configuration,
    then re-reads the full DNS server list to confirm the new entry is present,
    and finally reads system information to capture the node identity the change
    was applied to. Every step spells out its request inline so the flow can be
    read and executed without opening the underlying OpenAPI description.
