SSIGNMENT
The
KEY
attribute(s) for that device can be any of the attributes which are
assigned automatically by Traffix Manager, for example, NL Address and
NL Type. See “Predefined Attributes” on page 40 for a list of attributes
which are automatically assigned by Traffix Manager. If you have other
attribute lookup programs running, you may also use attributes which
have already been assigned by these programs as KEY attribute(s).
Using the dblookup
Program
The
dblookup
program assigns attributes to devices automatically based
upon lookup-tables stored in a database or a spreadsheet which you
provide. The source code for the
dblookup
program is provided in
c:\Transcend Traffix
Manager\TraffixServer\examples\vb\dblookup
while the
program itself is in
<installdir>\Traffix Server
.
Lookup Database
Structure
Access/Excel lookup tables have a common structure. The information
should be stored in tables named as follows, where N is a number
between 1 and 10 which determines how many key attributes the lookup
is based on (this is similar to the KEY: N line in
fileattrs
' configuration
file):
■
lookup_N:general lookup table;
or:
■
ARP_N:lookup table for ARP devices;
■
IP_N:lookup table for IP devices;
■
IPX_N:lookup table for IPX devices;
■
NetBEUI_N:lookup table for NetBEUI devices;
■
other_N:lookup table for other devices.
In each lookup table, the first N columns must be the key columns. In
Access, set the fields order in the table so that key attributes are
presented first. In Excel, the first column(s) are the key columns.
Note that there should be either one lookup_N table, or a set of
network-type lookup tables. If there is a lookup_N table as well as
network-type lookup tables,
dblookup
only looks up attributes from
lookup_N and ignores any other table. Also, there should be at most one
table of a given type: for example, if you create IP_1, IP_3 and IP_4 tables,
then IP_3 and IP_4 is ignored. It is permitted to have a restricted set of
