Expert Configuration
Server Leases In case the SpeedTouch™ DHCP server is running this table holds all leases which
are assigned by the DHCP server to (accepted) DHCP clients.
Following lease parameters are shown:
 Client ID:
The MAC address of the DHCP client.
 Address:
The IP address leased by the DHCP client.
 Pool:
The DHCP server address pool the lease IP address is taken from.
 TTL:
The DHCP server lease's Time To Live (in seconds).
For a permanent DHCP lease, TTL displays infinite.
 State:
The DHCP server lease state:
 Free (in case of statically added DHCP leases):
Indicating unused DHCP server leases. No DHCP request from this
particular Client ID has been received by the DHCP server (yet).
 Used:
Indicating assigned DHCP leases. A DHCP lease has been assigned to this
Client ID in the past (actually (Pool lease time)-TTL seconds ago).
As soon as a DHCP request is received, the SpeedTouch™ DHCP server will assign
the IP address matching the DHCP client's identity to this client (e.g. in case of a
renewal, or for static entries). If no pre-configured lease could be found in the table,
a new lease will be created when the client's request is granted.
DHCP leases can be added manually, e.g. for DHCP client devices that need a
"static" IP configuration. You can also remove existing DHCP leases
.
Existing DHCP leases can be made static (i.e. TTL infinite) by selecting the
DHCP lease and clicking Lock.
