Reset MAC & NAS Port

Overview​

These two actions clear a subscriber's device/port binding so they can re-bind on their next connection — used when a customer changes hardware or their line moves to a different port:

  • Reset MAC — clear the bound device MAC address.
  • Reset NAS Port ID — clear the bound port/interface.

Required Permissions​

  • Subscriber → Reset MAC and Reset NAS Port ID respectively.

Subscribers → (open a subscriber) → Reset MAC (header) and Other Actions ▾ → Reset NAS Port ID

Reset MAC​

The Reset MAC button clears the MAC address currently bound to the subscriber, so the next device that connects is learned as the new one. Use it when a customer replaces their router or device. It asks only for a Remark.

Reset NAS Port ID​

Other Actions ▾ → Reset NAS Port ID clears the bound port/interface (used together with NAS Port ID Check on the Technical Info tab). Use it when the customer's line is moved to a different port. It asks only for a Remark.

Important Notes​

  • These are only meaningful when MAC Check / NAS Port ID Check are on — those settings lock the subscriber to a specific device/port (an anti-sharing measure). Resetting temporarily unlocks the binding until the subscriber next connects and a new value is learned.
  • The subscriber may need to reconnect for the new binding to take effect.

Common Mistakes​

  • Resetting the MAC but the customer's device is offline, so nothing new is learned yet.
  • Expecting a reset to change speed or plan — it only affects device/port binding.
