Notes
Give certain
VINES traffic
(bridged over
Ethernet)
precedence over
all other traffic
Specify an
Ethernet Type field
of 0xBAD (VINES).
160 bits (sum of all
criteria that precede the
Destination Network field,
or
48+48+16+16+16+8+8)
32 bits Specify a
destination
network number
of 1234 (hex) as
the range value.
On a DLSw
circuit, filter on
NetBIOS Names.
DLS_DATA_START 376 (Destination
NetBIOS Names)
504 (Source NetBIOS
Names)
The offset of 376 only
applies if you want to filter
the beginning of the
NetBIOS name field. If
you want to find a
particular section of the
NetBIOS name, the offset
will increase by X * 8,
where X is the number of
bytes into the name that
you want to filter.
NetBIOS names
are up to 16 bytes
long. How they
are oriented in
the field (right
justified or left
justified) may be
dependent on
application and
should be
checked with an
analyzer before
creating filter
criteria.
To enter NetBIOS
Name ranges,
use the ASCII
equivalent of the
first 15 characters
in the name. For
names with less
than 15
characters, use
0x20 to pad
characters .
