Implementation guide
ISP RADIUS Server and Subscriber AAA
ISP RADIUS is an operating architecture, not just an authentication checkbox. This page frames the commercial and resilience questions; the RADIUS cluster covers protocol-specific implementation topics.
Use the interface and documentation together.
The capture below shows the related ISPbills product area. Follow the linked documentation for current fields and prerequisites, then validate the exact device, provider, software version, failure path and rollback before production use.
Plan the complete path, not one isolated setting.
Evaluate ISP RADIUS for centralized authentication, authorization, accounting, subscriber policy, NAS management and session control. Confirm the exact device, software version, provider contract and failure behavior in a representative environment before production rollout.
Centralize policy
Define the authoritative credential, package and eligibility source for supported access devices.
Design resilience
Document redundant paths, NAS failure behavior, time synchronization and observable error states.
Connect billing safely
Translate verified account state into access policy while retaining exception, session and audit context.
Prove the boundaries before automating them.
Record expected results, failure signals, the person who can approve a change, and the rollback path. Product support depends on the deployed architecture and integration version.

Implementation answers
What does an ISP RADIUS server do?
It evaluates authentication and authorization requests and records compatible accounting events from registered access devices.
Is RADIUS the billing system?
No. RADIUS provides AAA; billing determines charges, balances and commercial eligibility.
Can ISPbills connect RADIUS to MikroTik?
Yes. Supported MikroTik PPPoE and Hotspot services can use centralized FreeRADIUS workflows.
Bring the actual routers, access design, billing rules and failure cases.
