  product_train: API availability is stated per ISE release; Cisco publishes a resource-to-release matrix covering ISE 1.2
    through 3.6 Beta.

deprecation:

  published: true
  sunset_header: false
  deprecation_header: false
  window: A deprecated operation is supported in the release it was deprecated in and in the next release, and is removed
    in the one after. Deprecated in 3.2 means supported in 3.2 and 3.3, removed in 3.4.
  marking: Cisco states deprecated operations are marked in the OpenAPI description itself.
  observed: 'Not in the published documents. Zero of the 1,490 operations across the 103 harvested documents carry deprecated:
    true, even though the changelog records deprecations — Transport Gateway support was deprecated in the Licensing and System
    Settings APIs in ISE 3.3 Patch 2 and again in 3.4 GA. The stated marking convention is not reflected in the artifacts
    Cisco actually serves.'
  reserved_right: Cisco reserves the right to sunset deprecated operations sooner if necessary.

status_page: null
status_page_note: Cisco ISE is an on-premises/self-hosted product — availability is the customer's own appliance, so there
  is no per-service status page for it. status.cisco.com exists but is a Cisco Cloud Status hub for Cisco's SaaS offerings
  and does not carry an ISE component. No StatusPage pointer is emitted; asserting one would credit Cisco with an availability
  surface it does not publish for this product.
sla: null
sla_note: No published uptime SLA — appropriate for a self-hosted product. Cisco sells graduated support SKUs (SVS-ISE-SUP-B/S/E/P)
  instead.
support_lifecycle:
  end_of_life_policy: https://www.cisco.com/c/en/us/products/eos-eol-policy.html
  note: ISE follows Cisco end-of-sale/end-of-life bulletins per release rather than an API-level sunset schedule.
