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
mes-
sage. 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
4
.
When an UDP-Network is set, the validation for UDP queries received 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
Destina-
tions , if a match is found, a response is generated to the UDP destination
5
.
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:
A[AA.AAA.AAA.AAA]/B[B]
Chars Item Format Value Meaning
varies Network’s IP A[A...] Use ’U’ to undefine the UDP-Network (Default)
or enter any IP address that defines the UDP
network.
1-2 Network’s
mask B[B] 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:
>
SXAUN192.168.0.0/16
<
To tell the unit not to use an UDP network validation:
>
SXAUNU
<
On this last example, the UDP-Server port validation will still be done
by the IP-type, UDP-destinations single-match mechanism.

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