This page displays the currently active leases and their settings defined for FusionLayer DHCP servers. At most 20 leases are shown at once, and if there are more leases to show, browser links for navigating between sheets will be shown at the header of the data table.

The list contains the following items:

• IP Address: the ip address designated for a lease.
• MAC Address: the hardware (MAC) address used by a lease.
• Start: the lease starting time.
• End: the lease ending time.
• State: the lease state, whether it is active or not.
• UID: The uid statement records the client identifier used by the client to acquire the lease. Clients are not required to send client identifiers, and this statement only appears if the client did in fact send one. Client identifiers are normally an ARP type (1 for ethernet) followed by the MAC address.
• Circuit ID: The option agent.circuit-id and option agent.remote-id statements are used to record the circuit ID and remote ID options send by the relay agent, if the relay agent uses the relay agent information option. This allows these options to be used consistently in conditional evaluations even when the client is contacting the server directly rather than through its relay agent. These are also called as "option 82" values".
• Remote ID: The option agent.circuit-id and option agent.remote-id statements are used to record the circuit ID and remote ID options send by the relay agent, if the relay agent uses the relay agent information option. This allows these options to be used consistently in conditional evaluations even when the client is contacting the server directly rather than through its relay agent. These are also called as "option 82" values".
• Hostname: Most DHCP clients will send their hostname in the host-name option. If a client sends its hostname in this way, the hostname is recorded on the lease with a client-hostname statement. This is not required by the protocol, however, so many specialized DHCP clients do not send a host-name option.
