An UDP-Network can be set as a validation mechanism for UDP
queries originated to the unit’s UDP-Server Port configured with the
XAUP
message. The UDP-Network validation for the UDP-Server port
is optional as the validation is also done by looking for a match on
the IP-type, UDP
Destinations defined as IP-numbers
15
.
When an UDP-Network is set, the validation for UDP queries re-
ceived on the UDP-Server port starts with it. If a match is found, a
response is sent to the peer. If no UDP-Network match is found or
if an UDP-Network is not defined, a search for a match is done on
the IP-type, UDP-set
Destinations , if a match is found, a response
is generated to the UDP destination
16
. Finally if no match is found,
the query is silently discarded.
The UDP-Network is defined by a network’s IP and a mask. The
network’s IP is any IP address that defines the common IP addresses-
values among the members of the UDP-Network. The mask is defined
as the number of
ones from left to right which define the host-address
portion to validate on a peer’s IP address.
The message has the following format:
AAABBBCCCDDD/EE
Chars Item Format Value Meaning
3 1st number AAA 000-255 First number of the IP number. Use ’U’
to undefine the UDP-Network (Default) or
enter any IP address that defines the UDP
network.
3 2nd number BBB 000-255 Second number of the IP number.
3 3rd number CCC 000-255 Third number of the IP number.
3 4th number DDD 000-255 Fourth number of the IP number.
2 Network’s
mask EE 0-32 Number of set-bits from left to right that
define the mask.
For example, to set the UDP network as 172.29.1.x, use:
>
SXAUN172.29.1.0/24
<
To set the UDP network as 192.168.x.x, use:

UDP-Server port validation can only be done on IP-type destinations defined
as IP numbers but not with addresses defines with names.
