Required device integration, credentials or telemetry sources for Assurance are incomplete. NETCONF availability does not automatically enable the separate HTTPS RESTCONF service.

The change exists only in the candidate datastore because no supported NETCONF commit has been executed. NETCONF availability does not automatically enable the separate HTTPS RESTCONF service.

The device lacks effective NETCONF service or proper transport/session setup. NETCONF availability does not automatically enable the separate HTTPS RESTCONF service.

This test measures a different behavior: Establish a NETCONF session, inspect hello capabilities and read the intended datastore. It does not establish the target outcome. For the documented fault, the direct acceptance test is: send a GET to the supported RESTCONF data path and inspect JSON/XML and HTTP status.

This test measures a different behavior: Read the advertised :candidate capability, issue the authorized commit and inspect get-config of running to confirm the intended change. It does not establish the target outcome. For the documented fault, the direct acceptance test is: send a GET to the supported RESTCONF data path and inspect JSON/XML and HTTP status.

This test measures a different behavior: Inspect an affected client path/health issue and drill into specific device/interface evidence. It does not establish the target outcome. For the documented fault, the direct acceptance test is: send a GET to the supported RESTCONF data path and inspect JSON/XML and HTTP status.

That diagnosis is supported by a different symptom: An administrator assumes inventory registration alone automatically populates all assurance metrics without telemetry collection. Here the recorded observation is: an HTTPS RESTCONF request receives a service error even though a NETCONF SSH session succeeds. The applicable cause is: nETCONF availability does not automatically enable the separate HTTPS RESTCONF service.

That diagnosis is supported by a different symptom: SSH login works but NETCONF client cannot complete hello/capability negotiation. Here the recorded observation is: an HTTPS RESTCONF request receives a service error even though a NETCONF SSH session succeeds. The applicable cause is: nETCONF availability does not automatically enable the separate HTTPS RESTCONF service.

That diagnosis is supported by a different symptom: The candidate edit is successful, but operational interface configuration remains at its old value. Here the recorded observation is: an HTTPS RESTCONF request receives a service error even though a NETCONF SSH session succeeds. The applicable cause is: nETCONF availability does not automatically enable the separate HTTPS RESTCONF service.

That control reduces a separate risk: The device lacks effective NETCONF service or proper transport/session setup. For the described design, the recurring risk arises from: nETCONF availability does not automatically enable the separate HTTPS RESTCONF service. The specific required safeguard is: monitor management plane HTTPS certificates, ACL and API authorization on RESTCONF endpoints.

For the documented fault, the direct acceptance test is: read the advertised :candidate capability, issue the authorized commit and inspect get-config of running to confirm the intended change.

This test measures a different behavior: Preview intended differences and verify running configuration and compliance on a pilot device. It does not establish the target outcome. For the documented fault, the direct acceptance test is: read the advertised :candidate capability, issue the authorized commit and inspect get-config of running to confirm the intended change.

Setting the required hostname/domain and generating supported SSH host keys would not create local administrator usernames with appropriately protected secrets and make the VTY lines use local login under SSH.

Enabling SSH version 2 with appropriate local/domain keys and restricting VTY transport input to SSH would not create local administrator usernames with appropriately protected secrets and make the VTY lines use local login under SSH.

Configuring supported login security controls such as quiet-mode thresholds and login block-for on the appropriate IOS release would not create local administrator usernames with appropriately protected secrets and make the VTY lines use local login under SSH.

This test measures a different behavior: Attempt Telnet and SSH connections from an approved host and confirm only encrypted SSH is accepted. It does not establish the target outcome. For the documented fault, the direct acceptance test is: inspect VTY authentication settings and verify a named account succeeds while an unknown account is rejected.

This test measures a different behavior: Generate controlled failed logins and confirm a temporary lockout with useful audit events. It does not establish the target outcome. For the documented fault, the direct acceptance test is: inspect VTY authentication settings and verify a named account succeeds while an unknown account is rejected.

This test measures a different behavior: Inspect SSH server version/key status and complete a secure login from an authorized station. It does not establish the target outcome. For the documented fault, the direct acceptance test is: inspect VTY authentication settings and verify a named account succeeds while an unknown account is rejected.

That diagnosis is supported by a different symptom: An external host attempts unlimited SSH passwords without temporary throttling. Here the recorded observation is: an operator logs in with a shared line password without any user-specific accountability. The applicable cause is: the VTY lines use line password login rather than `login local` against named accounts.

That diagnosis is supported by a different symptom: SSH cannot start even though a local account and VTY login method exist. Here the recorded observation is: an operator logs in with a shared line password without any user-specific accountability. The applicable cause is: the VTY lines use line password login rather than `login local` against named accounts.

That diagnosis is supported by a different symptom: The router still accepts plaintext Telnet sessions after the administrator creates an RSA key. Here the recorded observation is: an operator logs in with a shared line password without any user-specific accountability. The applicable cause is: the VTY lines use line password login rather than `login local` against named accounts.

That control reduces a separate risk: VTY transport input still permits Telnet despite SSH being configured. For the described design, the recurring risk arises from: the VTY lines use line password login rather than `login local` against named accounts. The specific required safeguard is: audit named account lifecycle and remove unused break-glass credentials.

That control reduces a separate risk: Login attack mitigation thresholds and enforcement were not configured for the VTY service. For the described design, the recurring risk arises from: the VTY lines use line password login rather than `login local` against named accounts. The specific required safeguard is: audit named account lifecycle and remove unused break-glass credentials.

That control reduces a separate risk: The SSH server lacks required host key material or device identity prerequisites. For the described design, the recurring risk arises from: the VTY lines use line password login rather than `login local` against named accounts. The specific required safeguard is: audit named account lifecycle and remove unused break-glass credentials.

Bind an appropriate standard access-class to VTY management connections from the approved source subnet would not enable SSH version 2 with appropriate local/domain keys and restrict VTY transport input to SSH.

Setting the required hostname/domain and generating supported SSH host keys would not enable SSH version 2 with appropriate local/domain keys and restrict VTY transport input to SSH.

Creating local administrator usernames with appropriately protected secrets and making the VTY lines use local login under SSH would not enable SSH version 2 with appropriate local/domain keys and restrict VTY transport input to SSH.
