Parameter
Dst Port #
Precedence
Type of Service
If you are not familiar with Lucent packet filters, you can find background information in
Chapter 15, "Defining Static Filters." Standard IP filters use many of the same settings as TOS
filters.
Settings in RADIUS
In RADIUS, a TOS filter entry is a value of the Ascend-Filter attribute. To specify a TOS filter
value, use the following format:
iptos dir [ dstip n.n.n.n/nn ] [ srcip n.n.n.n/nn ][ proto ]
[ destport cmp value ] [ srcport cmp value ][ precedence value ]
[ type-of-service value ]
MAX 6000/3000 Network Configuration Guide
Specifies
Port number that the MAX compares with the destination port in a
packet. See RFC 1700 for a list of port numbers.
Priority level of the data stream. The three most significant bits of the
TOS byte are priority bits used to set precedence for priority queuing.
When TOS is enabled and the packet matches the filter, the bits can be
set to one of the following values (most significant bit first):
•
000—Normal priority
•
001—Priority level 1
•
010—Priority level 2
•
011—Priority level 3
•
100—Priority level 4
•
101—Priority level 5
•
110—Priority level 6
•
111—Priority level 7 (the highest priority)
Type of Service of the data stream. When TOS is enabled and the
packet matches the filter, you can specify one of the following values
in the packet:
•
Normal—Normal service
•
Cost—Minimize monetary cost
•
Reliability—Maximize reliability
•
Throughput—Maximize throughput
•
Latency—Minimize delay
Note: The four bits adjacent to the three most significant bits of the
TOS byte are used to choose a link according to the type of service.
