Note:
To make this assignment effective, use the SAVE command, and restart before exiting the maintenance com-
mand.
4. Setting ToS of DRS session:
This command is used to set the Quality of Service (QoS) of DRS. DRSTOS Precedence and DRSTOS Value
means IP Precedence and Diffserv respectively. Use one of the QoS and set the value to each parameter.
Note:
The result of data setting is indicated in 1-byte (HEX) format in accordance with the setting dialog followed
by prompt. The meaning of one bite data is as shown below:
STEP1:Determine precedence
Precedence: 0-7 (low-high) (default=6)
STEP2:Determine delay
0/1=Normal (Default)/Low Delay ON
STEP3 Determine throughput:
0/1=Normal (Default)/High Throughput ON
STEP4:Determine reliability:
0/1=Normal (Default)/High Reliability ON
STEP5:Determine cost
0/1=Normal (Default)/Cost Precedence ON
Result is shown
VS-32> SET DRSTOS PRECEDENCE
PRECEDENCE (0-7): 6
DELAY (0/1): 0
THROUGHPUT (0/1): 0
RELIABILITY (0/1): 0
COST (0/1): 0
