Helpdesk playbook

Find the lease, release it, or reserve the address. Operator role is enough.

Role operator can create reservations and force-release leases. Other writes 403. readonly can search only.

Fastest lookup: type the IP or MAC in the header search (Search). Open the hit. Use Leases when you need filters or force-release.

Helpdesk leases

“This MAC should get a new address”

  1. Header search, or Leases (/leases) → MAC aa:bb:cc:dd:ee:ff → Search.
  2. Open Detail if you need giaddr, DUID, granted node.
  3. Release → Confirm release. Inventory goes free (or stays reserved if a reservation exists). Outbox deletes A+PTR.
  4. Ask the client to renew. If it still holds the old IP, bounce the interface; DHCP does not unplug the NIC.

“This printer must always be .10”

Subnet page → Reservations. IP + MAC (and hostname). If .10 is already leased to someone else, release that lease first.

“User says they have no IP”

  • No Offer if Discover never answers.
  • NAK if they get a NAK.
  • Check Overview for dhcpd_stale / dhcpd_missing and pool bars.
