That observation verifies aaa source interface mismatch in a different situation, such as when aAA requests leave from an unexpected source IP that the policy server does not recognize as an authorized network device. For the reported aaa accounting records incident at a finance network core in Zurich, the required acceptance evidence is: The accounting server receives attributable start/stop or command records for tested sessions. This other result does not test that condition directly.

That observation verifies radius authentication transport in a different situation, such as when a router's RADIUS server is reachable by ICMP but RADIUS requests time out because authentication and accounting UDP ports are blocked.

This other result does not test that condition directly.

That observation verifies aaa method list not applied in a different situation, such as when the intended named login method list exists but VTY access continues to use another authentication path.

This other result does not test that condition directly.

That approach is relevant to catalyst center network health, such as when an enterprise shows widespread client connectivity failures but analysts inspect only a single switch device's CPU health. That is a different root cause from the catalyst center path trace fault observed at a research institution in Helsinki. Applying that approach alone would not establish the required result: The trace maps the observed path and isolates a failure segment or unsupported visibility boundary.

That approach is relevant to ip sla source interface, such as when an SLA probe reports failure because it leaves from the wrong source address or VRF compared with production application flows.

Applying that approach alone would not establish the required result: The trace maps the observed path and isolates a failure segment or unsupported visibility boundary.

That approach is relevant to catalyst center inventory credentials, such as when catalyst Center discovers a router's IP address but cannot collect configuration and health because management credentials are invalid. That is a different root cause from the catalyst center path trace fault observed at a research institution in Helsinki. Applying that approach alone would not establish the required result: The trace maps the observed path and isolates a failure segment or unsupported visibility boundary.

This other result does not test that condition directly.

That observation verifies dhcpv6 duid identity in a different situation, such as when an administrator assumes DHCPv6 reservations use only a client MAC address and the intended client consistently misses its reserved lease.

Applying that approach alone would not establish the required result: The receiving protocol's external route carries the documented tag for downstream policy.

That approach is relevant to route-map sequence numbering, such as when a new permit route-map entry is added after a broad permit any; its more-specific set action never runs. That is a different root cause from the route-map tag set fault observed at a university backbone in Sydney. Applying that approach alone would not establish the required result: The receiving protocol's external route carries the documented tag for downstream policy.

That observation verifies mutual redistribution metric integrity in a different situation, such as when bGP-origin routes entering EIGRP are given arbitrary seed metrics that make a slow backup path appear better than intended. For the reported route-map tag set incident at a university backbone in Sydney, the required acceptance evidence is: The receiving protocol's external route carries the documented tag for downstream policy. This other result does not test that condition directly.

That observation verifies ospf nssa type-7 translation in a different situation, such as when an NSSA ASBR originates an external route but routers outside the area never see a translated Type-5 LSA. For the reported route-map tag set incident at a university backbone in Sydney, the required acceptance evidence is: The receiving protocol's external route carries the documented tag for downstream policy. This other result does not test that condition directly.

That observation verifies ospf external summarization in a different situation, such as when an ASBR redistributing several adjacent external routes tries to use an ABR area range to summarize them. For the reported route-map tag set incident at a university backbone in Sydney, the required acceptance evidence is: The receiving protocol's external route carries the documented tag for downstream policy. This other result does not test that condition directly.

That approach is relevant to static hub mapping at spoke, such as when a spoke cannot send initial NHRP requests because it has no mapping from the hub's tunnel address to the reachable NBMA address. That is a different root cause from the spoke nhrp registration age fault observed at a remote clinic network in Melbourne. Applying that approach alone would not establish the required result: The hub retains current spoke mappings without expiration-related traffic loss.

That approach is relevant to nhrp cache verification, such as when a direct spoke route exists but its tunnel next hop lacks a corresponding NHRP resolution entry. That is a different root cause from the spoke nhrp registration age fault observed at a remote clinic network in Melbourne. Applying that approach alone would not establish the required result: The hub retains current spoke mappings without expiration-related traffic loss.

That approach is relevant to dmvpn nhs omission, such as when a spoke tunnel comes up but never registers with the hub because no Next Hop Server target is configured.

This other result does not test that condition directly.

That observation verifies flexible netflow exporter target in a different situation, such as when a flow monitor collects records locally but the collector receives nothing because its exporter destination is wrong.

This other result does not test that condition directly.

That approach is relevant to aaa exec authorization, such as when users pass login authentication but never receive authorized EXEC access because the required exec authorization method is missing. That is a different root cause from the aaa source interface mismatch fault observed at a health system WAN in Toronto. Applying that approach alone would not establish the required result: Server logs show the registered network-device source and authentication succeeds.

Applying that approach alone would not establish the required result: Server logs show the registered network-device source and authentication succeeds.

That approach is relevant to aaa server unavailable versus reject, such as when a router is configured TACACS+ then local, but an explicit reject from the active TACACS+ server is expected to trigger local fallback.

This other result does not test that condition directly.

That observation verifies aaa server group order in a different situation, such as when a local database is used first even when the desired policy requires TACACS+ primary authentication with local fallback only on error. For the reported aaa source interface mismatch incident at a health system WAN in Toronto, the required acceptance evidence is: Server logs show the registered network-device source and authentication succeeds. This other result does not test that condition directly.
