DescriptionField
Enter the number of minutes that a dynamically
assigned IP address can be in use, or leased. After
this time elapses, a client device has to request a
DHCP lease renewal. Use 0 to represent 1 day, 9999
never expire.
Default setting: 0
Client Lease Time
Provides provisioning server address information to
hosts that request this option. Server information can
be defined in one of three ways:
None: The ATA uses its own TFTP server to
source provisioning files, so it returns its own
local IP address to the client.
Remote TFTP Server: The ATA was
configured by using this method, and received
server information through Option 66 on its
WAN interface. In response to client requests,
it provides the remote TFTP server information.
Manual TFTP Server: Allows the manual
configuration of a configuration server address.
This option is used to provide either an IP
address or a fully qualified hostname. But the
ATA also accepts and offers a full URL
including protocol, path, and filename to meet
the requirements of specific clients.
Default setting: None
Option 66
If you chose Manual TFTP Server for Option 66,
enter the IP address, hostname, or URL of the TFTP
server.
Default setting: blank
TFTP Server
Provides a configuration or bootstrap filename to
hosts that request this option. This option is used with
option 66 to allow a client to form an appropriate
TFTP request for the file.
Default setting: blank
Option 67
Provides a configuration URL to clients that request
this option. An option 159 URL defines the protocol
and path information by using an IP address for clients
that cannot use DNS. For example:
https://10.1.1.1:888/configs/bootstrap.cfg
Default setting: blank
