DHCP Lease Statuses

The different lease statuses provide visibility into the state of IP address assignments and help you manage the DHCP pool effectively. IP address status designations are as follows:

  • free: The IP address is available in the DHCP pool and has not been assigned to any client. Typically, the Primary DHCP Failover server allocates free leases.

  • backup: The IP address is not assigned to a client by the DHCP Failover peer servers and can be assigned by any DHCP Failover peer server. This occurs during failover scenarios or when the active server is unavailable. Typically, the Secondary DHCP Failover server allocates backup leases.

  • active: The IP address is assigned to a client, and the lease is currently held by the active DHCP server.

  • abandoned: The IP address was previously assigned to a client, but the lease has expired, and the client has not renewed it. The IP address is not immediately available for reuse and may go through a waiting period before being returned to the free pool.

Each DHCP server of a failover pair acts as a backup for the DHCP leases of its peer. For example, the DHCP server of EdgeConnect-1 hands an IP lease to a client 172.23.2.50. This IP address shows as active on both of the EdgeConnect-1 and EdgeConnect-2 DHCP Failover peer servers.
