That diagnosis is supported by a different symptom: A small volume of repeated SNMP requests causes control-plane slowdown without link saturation. Here the recorded observation is: traffic destined to the router CPU remains unpoliced although a transit-forwarding ACL exists. The applicable cause is: data-plane interface ACL enforcement was mistaken for explicit control-plane policing.

That diagnosis is supported by a different symptom: The CPU becomes saturated because excessive punted packets reach the routing process. Here the recorded observation is: traffic destined to the router CPU remains unpoliced although a transit-forwarding ACL exists.

The applicable cause is: data-plane interface ACL enforcement was mistaken for explicit control-plane policing.

That control reduces a separate risk: Management traffic is processed in the CPU and lacks suitable control-plane rate controls. For the described design, the recurring risk arises from: data-plane interface ACL enforcement was mistaken for explicit control-plane policing. The specific required safeguard is: audit device-destined management and routing packets separately from transit forwarding.

That control reduces a separate risk: The control plane lacks an effective policing policy for the abusive punt class. For the described design, the recurring risk arises from: data-plane interface ACL enforcement was mistaken for explicit control-plane policing. The specific required safeguard is: audit device-destined management and routing packets separately from transit forwarding.

That control reduces a separate risk: A platform-inappropriate policing threshold throttles essential control-plane traffic. For the described design, the recurring risk arises from: data-plane interface ACL enforcement was mistaken for explicit control-plane policing. The specific required safeguard is: audit device-destined management and routing packets separately from transit forwarding.

Correcting the CoPP class and policing rate for authorized OSPF control traffic rather than opening all packets would not address the need for tune control-plane policing rates and traffic classes for real platform traffic levels and route-scale demands.

Rate-limit or classify SNMP management-plane traffic through appropriate CoPP/management controls would not address the need for tune control-plane policing rates and traffic classes for real platform traffic levels and route-scale demands.

Applying supported CoPP or control-plane protection to the punt path in addition to relevant interface ACLs would not address the need for tune control-plane policing rates and traffic classes for real platform traffic levels and route-scale demands.

This test measures a different behavior: Compare CPU load, CoPP counters and authorized monitoring success before and after tuning. It does not establish the target outcome. For the documented fault, the direct acceptance test is: stress-test legitimate BGP update bursts and verify adjacency stability plus CoPP drop counters.

That control reduces a separate risk: Data-plane interface ACL enforcement was mistaken for explicit control-plane policing. For the described design, the recurring risk arises from: a platform-inappropriate policing threshold throttles essential control-plane traffic. The specific required safeguard is: review CoPP against platform defaults and route scale during hardware refresh.

That control reduces a separate risk: Legitimate routing-control packets are mistakenly classified into a low-rate drop class. For the described design, the recurring risk arises from: a platform-inappropriate policing threshold throttles essential control-plane traffic. The specific required safeguard is: review CoPP against platform defaults and route scale during hardware refresh.

That control reduces a separate risk: Management traffic is processed in the CPU and lacks suitable control-plane rate controls. For the described design, the recurring risk arises from: a platform-inappropriate policing threshold throttles essential control-plane traffic. The specific required safeguard is: review CoPP against platform defaults and route scale during hardware refresh.

Enforcing per-resource API authorization/roles and checking the effective action scope for each authenticated principal would not meet the need for hTTPS/TLS with trusted server certificate validation for the management API.

Moving the token to a protected runtime secret store and rotate the exposed credential would not meet the need for hTTPS/TLS with trusted server certificate validation for the management API.

Implementing bounded exponential backoff, honor Retry-After where provided and using idempotent operation handling would not meet the need for hTTPS/TLS with trusted server certificate validation for the management API.

This test measures a different behavior: Simulate HTTP429 responses and verify the script delays retries without duplicate objects. It does not establish the target outcome. For the documented fault, the direct acceptance test is: inspect TLS certificate chain and successful authorized HTTPS session to RESTCONF.

This test measures a different behavior: Test authorized GET and forbidden POST/DELETE using low-privilege credentials. It does not establish the target outcome. For the documented fault, the direct acceptance test is: inspect TLS certificate chain and successful authorized HTTPS session to RESTCONF.

This test measures a different behavior: Verify repository history no longer provides active usable token access and the rotated token works under approved scope. It does not establish the target outcome. For the documented fault, the direct acceptance test is: inspect TLS certificate chain and successful authorized HTTPS session to RESTCONF.

That diagnosis is supported by a different symptom: An unauthorized collaborator reuses the committed token to call management APIs. Here the recorded observation is: a client ignores invalid certificates and sends credentials to an untrusted management endpoint. The applicable cause is: the API client disables TLS peer verification and cannot authenticate the server.

That diagnosis is supported by a different symptom: Bursting retries overwhelm the controller while some POST requests complete twice. Here the recorded observation is: a client ignores invalid certificates and sends credentials to an untrusted management endpoint. The applicable cause is: the API client disables TLS peer verification and cannot authenticate the server.

That diagnosis is supported by a different symptom: A read-only automation identity can invoke configuration-changing HTTP methods. Here the recorded observation is: a client ignores invalid certificates and sends credentials to an untrusted management endpoint. The applicable cause is: the API client disables TLS peer verification and cannot authenticate the server.

That control reduces a separate risk: Authentication succeeds but API authorization does not restrict modifying operations. For the described design, the recurring risk arises from: the API client disables TLS peer verification and cannot authenticate the server. The specific required safeguard is: rotate certificates and pin/validate appropriate CAs without disabling TLS checks.

That control reduces a separate risk: The client treats rate limiting as an immediate failure loop without safe retry/idempotency design. For the described design, the recurring risk arises from: the API client disables TLS peer verification and cannot authenticate the server. The specific required safeguard is: rotate certificates and pin/validate appropriate CAs without disabling TLS checks.

That control reduces a separate risk: The API bearer token was embedded in accessible source code and never revoked. For the described design, the recurring risk arises from: the API client disables TLS peer verification and cannot authenticate the server. The specific required safeguard is: rotate certificates and pin/validate appropriate CAs without disabling TLS checks.

Implementing bounded exponential backoff, honor Retry-After where provided and using idempotent operation handling would not enforce per-resource API authorization/roles and check the effective action scope for each authenticated principal.

The needed correction is to enforce per-resource API authorization/roles and check the effective action scope for each authenticated principal.

Using HTTPS/TLS with trusted server certificate validation for the management API would not enforce per-resource API authorization/roles and check the effective action scope for each authenticated principal.
