V7122 GatewayUser Guide
If ARP Manipulation is enabled, the following two commands are available.
Reply Type:
Reply to a BootRequest can be either
Broadcast
or
Unicast
. The default
for the BootP Tool is
Broadcast
. In order for the reply to be set to
Unicast
, ARP
Manipulation must first be enabled. This then enables the BootP Tool to find the MAC
address for the client in the ARP cache so that it can send a message directly to the
requesting device. Normally, this setting can be left at
Broadcast
.
ARP Type:
The type of entry made into the ARP cache on the computer, once
ARP
Manipulation
is enabled, can be either
Dynamic
or
Static
. Dynamic entries expire after
a period of time, keeping the cache clean so that stale entries do not consume computer
resources. The Dynamic setting is the default setting and the setting most often used.
Static entries do not expire.
Number of Timed Replies:
This feature is useful for communicating to VoIP gateways
that are located behind a firewall that would block their BootRequest messages from
getting through to the computer that is running the BootP Tool. You can set this value to
any whole digit. Once set, the BootP Tool can send that number of BootReply messages
to the destination immediately after you send a remote reset to a VoIP gateway at a valid
IP address. This enables the replies to get through to the VoIP gateway even if the
BootRequest is blocked by the firewall. To turn off this feature, set the
Number of Timed
Replies
= 0.
TFTP Preferences
Enabled:
To enable the TFTP functionality of the BootP Tool, select the check box. If
you want to use another TFTP application, other than the one included with the BootP
Tool, unselect the box.
On Interface:
This pull down menu displays all network interfaces currently available on
the computer. Select the interface that you want to use for the TFTP. Normally, there is
only one choice.
Directory:
This option is enabled only when the TFTP is enabled. Use this parameter to
specify the folder that contains the files for the TFTP utility to manage (
cmp
,
ini
, Call
Progress Tones, and the like).
Boot File Mask:
Boot File Mask specifies the file extension used by the TFTP utility for
the boot file that is included in the BootReply message. This is the file that contains VoIP
gateway software and normally appears as
cmp
.
ini
File Mask:
ini
File mask specifies the file extension used by the TFTP utility for the
configuration file that is included in the BootReply message. This is the file that contains
VoIP gateway configuration parameters and normally appears as
ini
.
Timeout:
This specifies the number of seconds that the TFTP utility waits before
retransmitting TFTP messages. This can be left at the default value of 5 (the more
congested your network, the higher the value you should define in these fields).
Maximum Retransmissions:
This specifies the number of times that the TFTP utility
tries to resend messages after timing out. This can be left at the default value of 10 (the
more congested your network, the higher the value you should define in these fields).
